1 Notmuch 0.27 (UNRELEASED)
2 =========================
7 Add support for thread:{} queries
9 Queries of the form `thread:{foo} and thread:{bar}` match threads
10 containing (possibly distinct) messages matching foo and bar. See
11 `notmuch-search-terms(7)` for details.
16 As of this release, support for versions of Xapian before 1.4.0 is
17 deprecated, and may disappear in a future release of notmuch.
19 Notmuch 0.26.2 (2018-04-28)
20 ===========================
25 Work around Xapian bug with `get_mset(0,0, x)`.
27 This causes aborts in `_notmuch_query_count_documents` on
28 e.g. Fedora 28. The underlying bug is fixed in Xapian commit
29 f92e2a936c1592, and will be fixed in Xapian 1.4.6.
31 Make thread indexing more robust against reference loops
33 Choose a thread root by date in case of reference loops. Fix a
34 related abort in `notmuch show`.
36 Notmuch 0.26.1 (2018-04-02)
37 ===========================
42 Bump the library minor version. This should have happened in 0.26, but
43 better late than never.
46 Notmuch 0.26 (2018-01-09)
47 =========================
49 Command Line Interface
50 ----------------------
52 Support for re-indexing existing messages
54 There is a new subcommand, `notmuch reindex`, which re-indexes all
55 messages matching supplied search terms. This permits users to
56 change the way specific messages are indexed.
58 Note that for messages with multiple variants in the message
59 archive, the recorded Subject: of may change upon reindexing,
60 depending on the order in which the variants are indexed.
62 Improved error reporting in notmuch new
64 Give more details when reporting certain Xapian exceptions.
66 Support maildir synced tags in `new.tags`
68 Tags `draft`, `flagged`, `passed`, and `replied` are now supported
69 in `new.tags`. The tag `unread` is still special in the presence of
70 maildir syncing, and will be added for files in `new/` regardless of
71 the setting of `new.tags`.
73 Support /regex/ in new.ignore
75 Files and directories may be ignored based on regular expressions.
77 Allow `notmuch insert --folder=""`
79 This inserts into the top level folder.
81 Strip trailing '/' from folder path for notmuch insert
83 This prevents a potential problem with duplicated database records.
85 New option --output=address for notmuch address
87 Make `notmuch show` more robust against deleting duplicate files
89 The option --decrypt now takes an explicit argument
91 The --decrypt option to `notmuch show` and `notmuch reply` now takes
92 an explicit argument. If you were used to invoking `notmuch show
93 --decrypt`, you should switch to `notmuch show --decrypt=true`.
95 Boolean and keyword arguments now take a `--no-` prefix
100 Indexing cleartext of encrypted e-mails
102 It's now possible to include the cleartext of encrypted e-mails in
103 the notmuch index. This makes it possible to search your encrypted
104 e-mails with the same ease as searching cleartext. This can be done
105 on a per-message basis by passing --decrypt=true to indexing
106 commands (new, insert, reindex), or by default by running "notmuch
107 config set index.decrypt true".
109 Encrypted messages whose cleartext is indexed will typically also
110 have their session keys stashed as properties associated with the
111 message. Stashed session keys permit rapid rendering of long
112 encrypted threads, and disposal of expired encryption-capable keys.
113 If for some reason you want cleartext indexing without stashed
114 session keys, use --decrypt=nostash for your indexing commands (or
115 run "notmuch config set index.decrypt nostash"). See `index.decrypt`
116 in notmuch-config(1) for more details.
118 Note that stashed session keys permit reconstruction of the
119 cleartext of the encrypted message itself, and the contents of the
120 index are roughly equivalent to the cleartext as well. DO NOT USE
121 this feature without considering the security of your index.
126 Guard against concurrent searches in notmuch-tree
128 Use make-process when available
130 This allows newer Emacs to separate stdout and stderr from the
131 notmuch command without using temporary files.
136 Indexing files with duplicate message-id
138 Files with duplicate message-id's are now indexed, and searchable
139 via terms and phrases. There are known issues related to
140 presentation of results and regular-expression search, but in
141 principle no mail file should be completely unsearchable now.
143 New functions to count files
145 Two new functions in the libnotmuch API:
146 `notmuch_message_count_files`, and `notmuch_thread_get_total_files`.
148 New function to remove properties
150 A new function was added to the libnotmuch API to make it easier to
151 drop all properties with a common pattern:
152 `notmuch_message_remove_all_properties_with_prefix`
154 Change of return value of `notmuch_thread_get_authors`
156 In certain corner cases, `notmuch_thread_get_authors` previously
157 returned NULL. This has been replaced by an empty string, since the
158 possibility of NULL was not documented.
160 Transition `notmuch_database_add_message` to `notmuch_database_index_file`
162 When indexing an e-mail message, the new
163 `notmuch_database_index_file` function is the preferred form, and
164 the old `notmuch_database_add_message` is deprecated. The new form
165 allows passing a set of options to the indexing engine, which the
166 operator may decide to change from message to message.
173 The test suite now works properly with out-of-tree builds, i.e. with
174 separate source and build directories. The --root option to tests
175 has been dropped. The same can now be achieved more reliably using
181 Python bindings specific Debian packaging is removed
183 The bindings have been build by the top level Debian packaging for a
184 long time, and `bindings/python/debian` has bit-rotted.
186 Open mail files in binary mode when using Python 3
188 This avoids certain encoding related crashes under Python 3.
190 Add python bindings for `notmuch_database_{get,set}_config*`
192 Optional `decrypt_policy` flag is available for notmuch.database().index_file()
197 nmbug's internal version increases to 0.3 in this notmuch release.
198 User-facing changes with this notmuch release:
200 * Accept failures to unset `core.worktree` in `clone`, which allows
201 nmbug to be used with Git 2.11.0 and later.
202 * Auto-checkout in `clone` if it wouldn't clobber existing content,
203 which makes the initial clone more convenient.
204 * Only error for invalid diff lines in `tags/`, which allows for
205 `README`s and similar in nmbug repositories.
210 New man page: notmuch-properties(7)
212 This new page to the manual describes common conventions for how
213 properties are used by libnotmuch, the CLI, and associated programs.
214 External projects that use properties are encouraged to claim their
215 properties and conventions here to avoid collisions.
217 Notmuch 0.25.3 (2017-12-08)
218 ===========================
223 Extend mitigation (disabling handling x-display in text/enriched) for
224 Emacs bug #28350 to Emacs versions before 24.4 (i.e. without
227 Command Line Interface
228 ----------------------
230 Correctly report userid validity. Fix test suite failure for GMime >=
231 3.0.3. This change raises the minimum supported version of GMime 3.x
234 Notmuch 0.25.2 (2017-11-05)
235 ===========================
237 Command Line Interface
238 ----------------------
240 Fix segfault in notmuch-show crypto handling when compiled against
241 GMime 2.6; this was a regression in 0.25.
246 Support for GMime before 3.0 is now deprecated, and will be removed in
249 Notmuch 0.25.1 (2017-09-11)
250 ===========================
255 Disable handling x-display in text/enriched messages. Mitigation for
258 Notmuch 0.25 (2017-07-25)
259 =========================
264 Add regexp searching for mid, paths, and tags.
266 Skip HTML tags when indexing
268 In particular this avoids indexing large inline images.
270 Command Line Interface
271 ----------------------
273 Bash completion is now installed to /usr/share by default.
275 Allow space as separator for keyword arguments.
280 Support for stashing message timestamp in show and tree views
282 Invoking `notmuch-show-stash-date` with a prefix argument
283 stashes the unix timestamp of the current message instead of
286 Don't use 'function' as variable name, workaround emacs bug 26406.
291 Add workaround for date parsing of bad input in older GMime
293 In certain circumstances, older GMime libraries could return
294 negative numbers when parsing syntactically invalid dates.
296 Replace deprecated functions with status returning versions
298 API of notmuch_query_{search,count}_{messages,threads} has
299 changed. notmuch_query_add_tag_exclude now returns a status
302 Add support for building against GMime 3.0.
304 Rename libutil.a to libnotmuch_util.a.
306 libnotmuch SONAME is incremented to libnotmuch.so.5.
308 Notmuch 0.24.2 (2017-06-01)
309 ===========================
311 Command Line Interface
312 ----------------------
314 Fix output from `notmuch dump --include=properties` to not include tags.
319 Fix filename stashing in tree view.
321 Notmuch 0.24.1 (2017-04-01)
322 ===========================
327 Fix regressions in non-regexp search for `from:` and `subject:`
329 The regexp search code in 0.24 introduced a regression in the
330 handling of empty queries and wildcards. These are both corrected in
333 Command Line Interface
334 ----------------------
336 Fix several memory leaks in `notmuch show`
338 Update NEWS for 0.24 to mention schema changes
340 Fix bug in dump header
342 The previous version of the dump header failed to mention the
343 inclusion of tags. This fix bumps the version number of the dump
344 format to 3. There are no other changes to the format.
349 Fix a read-after-free in the library.
351 Notmuch 0.24 (2017-03-12)
352 =========================
357 Regular expression searches supported for `from:` and `subject:`
359 This requires recent Xapian (1.4+) See notmuch-search-terms(7) for
362 Command Line Interface
363 ----------------------
365 Run external `notmuch-` prefixed commands as subcommands
367 You can now add your own `notmuch-` prefixed commands in PATH, and
368 have notmuch run them as if they were notmuch commands. See the
369 `notmuch(1)` man page for details
371 New default output format to 3
373 See devel/schemata for details. Users of the structured output
374 format are reminded of the `--format-version` argument to `notmuch
375 show` and `notmuch search` which can prevent breakage when the
376 default format changes.
381 Postpone and resume messages in `notmuch-message-mode` (composition)
383 Notmuch now has built in support for postponing, saving and resuming
384 messages. The default bindings are C-x C-s to save a draft, C-c C-p
385 to postpone a draft (save and exit compose buffer), and "e" in show
386 or tree view to resume.
388 Draft messages are tagged with `notmuch-draft-tags` (draft by
389 default) so you may wish to add that to the excluded tags list. When
390 saving a previously saved draft message the earlier draft gets
393 Note that attachments added before postponing will be included as
394 they were when you postponed in the final message.
398 It is now possible to save the list of address completions for
399 notmuch's internal completion between runs of emacs. This makes the
400 first calls to address completion much better and faster. For
401 privacy reasons it is disabled by default, to enable set or
402 customize `notmuch-address-save-filename`.
406 It is now possible to configure tagging shortcuts (with an interface
407 like notmuch jump). For example (by default) k u will remove the
408 unread tag, and k s will add a tag "spam" and remove the inbox
409 tag. Pressing k twice will do the reverse operation so, for example,
410 k k s removes the spam tag and adds the inbox tag. See the customize
411 variable `notmuch-tagging-keys` for more information.
415 It is now possible to refresh all notmuch buffers to reflect the
416 current state of the database with a single command, `M-=`.
418 Stop display of `application/*` parts
420 By default gnus displays all `application/*` parts such as
421 application/zip in the message buffer. This has several undesirable
422 effects for notmuch (security, triggering errors etc). Notmuch now
423 overrides this and does not display them by default. If you have
424 customized `mm-inline-override-types` then we assume you know what
425 you want and do not interfere; if you do want to stop the display of
426 `application/*` add `application/*` to your customization. If you want
427 to allow `application/*` then set `mm-inline-override-types` to
430 Small change in the api for notmuch-search-tag
432 When `notmuch-search-tag` is called non-interactively and the region
433 is set, then it only tags the threads in the region. (Previously it
434 only tagged the current thread.)
436 Bugfix for sending messages with very long headers
438 Previously emacs didn't fold very long headers when sending which
439 could cause the MTA to refuse to send the message. This makes sure
440 it does fold any long headers so the message is RFC compliant.
442 `notmuch emacs-mua` command installed with the Emacs interface
444 We've carried a `notmuch-emacs-mua` script in the source tree for
445 quite some time. It can be used to launch the Notmuch Emacs
446 interface from the command line in many different ways. Starting
447 with this release, it will be installed with the Emacs
448 interface. With the new external subcommand support, the script
449 transparently becomes a new notmuch command. See the
450 `notmuch-emacs-mua(1)` man page for details.
452 Notmuch Emacs desktop integration
454 The desktop integration file will now be installed with the Notmuch
455 Emacs interface, adding a Notmuch menu item and configuration to
456 allow the user to set up Notmuch Emacs as the `mailto:` URL handler.
461 `notmuch_query_count_messages` is now non-destructive
463 Internally the implementation of excludes has changed to make this
466 Improved handling of DatabaseModifiedError
468 Previously uncaught exceptions reading message metadata are now
471 Notmuch 0.23.7 (2017-02-28)
472 ===========================
477 Drop use of gpgconf --create-socketdir. Move $GNUPGHOME to /tmp.
479 It turns out the hardcoded use of /run/user in gpg doesn't work out
480 that well in some environments. The more low tech fix is to move all
481 of $GNUPGHOME to somewhere where we can control the length of the
484 Notmuch 0.23.6 (2017-02-27)
485 ===========================
487 Command Line Interface
488 ----------------------
490 Fix read-after-free bug in `notmuch new`.
495 Use gpgconf --create-socketdir if available.
497 GnuPG has a facility to use sockets in /run or /var/run to avoid
498 problems with long socket paths, but this is not enabled by default
499 for GNUPGHOME other than $HOME/.gnupg. Enable it, if possible.
501 Notmuch 0.23.5 (2017-01-09)
502 ===========================
507 Fix quoting bug in configure. This had introduced a RUNPATH into the
508 notmuch binary in cases where it was not not needed.
510 Notmuch 0.23.4 (2016-12-24)
511 ===========================
513 Command Line Interface
514 ----------------------
516 Improve error handling in notmuch insert
518 Database lock errors no longer prevent message file delivery to the
519 filesystem. Certain errors during `notmuch insert` most likely to
520 be temporary return EX_TEMPFAIL.
525 Restore autoload cookie for notmuch-search.
527 Notmuch 0.23.3 (2016-11-27)
528 ===========================
530 Command Line Interface
531 ----------------------
533 Treat disappearing files during notmuch new as non-fatal.
538 Fix incompatibility (related to signature size) with gnupg 2.1.16.
540 Notmuch 0.23.2 (2016-11-20)
541 ===========================
546 Fix notmuch-interesting-buffer and notmuch-cycle-notmuch-buffers.
548 notmuch-tree-mode and notmuch-message-mode buffers are now
549 considered interesting by `notmuch-interesting-buffer` and
550 `notmuch-cycle-notmuch-buffers`.
552 Restore compatibility with Emacs 23.
554 Notmuch support for Emacs 23 is now deprecated.
556 Notmuch 0.23.1 (2016-10-23)
557 ===========================
562 Require Xapian >= 1.2.6
564 The ifdef branch for older Xapian (pre-compact API) had bit-rotted.
569 Fix default colours for unread and flagged messages
571 In 0.23 the default colours for unread and flagged messages in
572 search view were accidentally swapped. This release returns them to
573 the original colours.
575 A related change in 0.23 broke the customize widget for
576 notmuch-search-line-faces. This is now fixed.
578 Fix test failure with Emacs 25.1
580 A previously undiscovered jit-lock related bug was exposed by Emacs
581 25, causing a notmuch-show mode test to fail. This release fixes the
582 bug, and hence the test.
584 Notmuch 0.23 (2016-10-03)
585 =========================
587 General (Xapian 1.4+)
588 ---------------------
590 Compiling against Xapian 1.4 enables several new features.
592 Support for single argument date: queries
594 `date:<expr>` is equivalent to `date:<expr>..<expr>`.
596 Support for blocking opens
598 When opening a database notmuch by default will wait for another
599 process to release a write lock, rather than returning an error.
601 Support for named queries
603 Named queries (also known as 'saved searches') can be defined with a
604 `query:name` format. The expansion of these queries is stored in the
605 database and they can be used from any notmuch client.
612 libnotmuch now supports the attachment of arbitrary key-value pairs
613 to messages. These can be used by various tools to manage their
614 private data without polluting the user tag space. They also support
615 iteration of values with the same key or same key prefix.
617 Bug fix for `notmuch_directory_set_mtime`
619 Update cached mtime to match on-disk mtime.
624 Support for compile time options
626 A group of `built_with` keys is now supported for notmuch
627 config. Initial keys in this group are `compact`, `field_processor`,
630 Dump/Restore support for configuration information and properties
632 Any configuration information stored in the database (initially just
633 named queries) is dumped and restored. Similarly any properties
634 attached to messages are also dumped and restored. Any new
635 information in the dump format is prefixed by '#' to allow existing
636 scripts to ignore it.
641 Make notmuch-message-mode use insert for fcc
643 Notmuch-message-mode now defaults to using notmuch insert for
644 fcc. The old file based fcc behaviour can be restored by setting the
645 defcustom `notmuch-maildir-use-notmuch-insert` to nil.
647 When using notmuch insert, `notmuch-fcc-dirs` must be a subdirectory
648 of the mailstore (absolute paths are not permitted) followed by any
649 tag changes to be applied to the inserted message. The tag changes
650 are applied after the default tagging for new messages. For example
651 setting the header to "sentmail -inbox +sent" would insert the
652 message in the subdirectory sentmail of the mailstore, add the tag
653 "sent", and not add the (normally added) "inbox" tag.
655 Finally, if the insert fails (e.g. if the database is locked) the
656 user is presented with the option to retry, ignore, or edit the
659 Make internal address completion customizable
661 There is a new defcustom `notmuch-address-internal-completion` which
662 controls how the internal completion works: it allows the user to
663 choose whether to match on messages the user sent, or the user
664 received, and to filter the messages used for the match, for example
667 Allow internal address completion on an individual basis
669 There is a new function `notmuch-address-toggle-internal-completion`
670 (by default it has no keybinding) which allows users who normally
671 use an external completion command to use the builtin internal
672 completion for the current buffer.
674 Alternatively, if the user has company-mode enabled, then the user
675 can use company mode commands such as `company-complete` to
676 activate the builtin completion for an individual completion.
680 The function `notmuch-show-resend-message` (bound to `b` in show
681 and tree modes) will (attempt to) send current message to new
682 recipients. The headers of the message won't be altered (e.g. `To:`
683 may point to yourself). New `Resent-To:`, `Resent-From:` and so on
684 will be added instead.
686 Face customization is easier
688 New faces `notmuch-tag-unread`, `notmuch-tag-flagged`,
689 `notmuch-tag-deleted`, `notmuch-tag-added`,
690 `notmuch-search-flagged-face` and `notmuch-search-unread-face` are
691 now used by default. Customize `notmuch-faces` to modify them.
693 Omit User-Agent header by default when sending mail
698 Add support for `notmuch_database_get_all_tags`
703 Go bindings moved to contrib
705 Add support for `notmuch_threads_t` and `notmuch_thread_t`
707 Fixed constant values so they are not all zero anymore
709 Previously, it was impossible to open writable database handles,
710 because `DATABASE_MODE_READ_ONLY` and `DATABASE_MODE_READ_WRITE` were
712 The same issue occurred with sort modes.
714 Notmuch 0.22.2 (2016-09-08)
715 ===========================
722 Have gdb write to a log file instead of stdout, hiding some more
723 (harmless) stderr chatter which causes test failures.
725 Hardcode fingerprint in PGP/MIME tests
727 Make the tests more robust against changing GnuPG output formats.
729 Notmuch 0.22.1 (2016-07-19)
730 ===========================
735 Correct the definition of `LIBNOTMUCH_CHECK_VERSION`.
737 Document the (lack of) operations permitted on a closed database.
742 Fix race condition in dump / restore tests.
747 Use `env` to locate perl.
752 Tell `message-mode` mode that outgoing messages are mail
754 This makes message-mode configuration behave more predictably.
756 Respect charset of MIME parts when reading them
758 Fix previous assumption that everyone uses UTF-8.
760 Notmuch 0.22 (2016-04-26)
761 =========================
768 Notmuch should now build (and the test suite should pass) on recent
769 releases of Xapian 1.3.x. It has been tested with Xapian 1.3.5.
771 Limited support for S/MIME messages
773 Signature verification is supported, but not decryption. S/MIME
774 signature creation and S/MIME encryption are supported via built-in
775 support in Emacs. S/MIME support is not extensively tested at this
780 Fix for threading bug involving deleting and re-adding
781 messages. Fix for case-sensitive content disposition headers. Fix
782 handling of 1 character directory names at top level.
784 Command Line Interface
785 ----------------------
787 `notmuch show` now supports verifying S/MIME signatures
789 This support relies on an appropriately configured `gpgsm`.
794 Drop dependency on "pkg-config emacs".
799 Notmuch replies now include all parts shown in the show view
801 There are two main user visible changes. The first is that rfc822
802 parts are now included in replies.
804 The second change is that part headers are now included in the reply
805 buffer to provide visible separation of the parts. The choice of
806 which part headers to show is customizable via the variable
807 `notmuch-mua-reply-insert-header-p-function`.
809 Filtering or Limiting messages is now bound to `l` in the search view
811 This binding now matches the analogous binding in show view.
813 `F` forwards all open messages in a thread
815 When viewing a thread of messages, the new binding `F` can be used
816 to generate a new outgoing message which forwards all of the open
817 messages in the thread. This is analogous to the `f` binding, which
818 forwards only the current message.
820 Preferred content type can be determined from the message content
822 More flexibility in choosing which sub-part of a
823 multipart/alternative part is initially shown is available by
824 setting `notmuch-multipart/alternative-discouraged` to a function
825 that returns a list of discouraged types. The function so specified
826 is passed the message as an argument and can examine the message
827 content to determine which content types should be discouraged. This
828 is in addition to the current capabilities (i.e. setting
829 `notmuch-multipart/alternative-discouraged` to a list of discouraged
832 When viewing a thread ("show" mode), queries that match no messages no
833 longer generate empty buffers
835 Should an attempt be made to view the thread corresponding to a
836 query that matches no messages, a warning message is now displayed
837 and the terminal bell rung rather than displaying an empty buffer
838 (or, in some cases, displaying an empty buffer and throwing an
839 error). This also affects re-display of the current thread.
841 Handle S/MIME signatures in emacs
843 The emacs interface is now capable making and verifying S/MIME
846 `notmuch-message-address-insinuate` is now a no-op
848 This reduces the amount of interference with non-notmuch uses of
851 Address completion improvements
853 An external script is no longer needed for address completion; if
854 you previously configured one, customize the variable
855 `notmuch-address-command` to try the internal completion. If
856 `company-mode` is available, notmuch uses it by default for
857 interactive address completion.
859 Test and experiment with the emacs MUA available in source tree
861 `./devel/try-emacs-mua` runs emacs and fills the window with
862 information how to try the MUA safely. Emacs is configured to use
863 the notmuch (lisp) files located in `./emacs` directory.
868 New `notmuch-report(1)` and `notmuch-report.json(5)` man pages
869 describe `notmuch-report` and its JSON configuration file. You can
870 build these files by running `make` in the `devel/nmbug/doc`
876 Renamed from `nmbug-status`. This script generates reports based on
877 notmuch queries, and doesn't really have anything to do with nmbug,
878 except for sharing the `NMBGIT` environment variable. The new name
879 focuses on the script's action, instead of its historical association
880 with the nmbug workflow. This should make it more discoverable for
881 users looking for generic notmuch reporting tools.
883 The default configuration file name (extracted from the `config`
884 branch of `NBMGIT` has changed from `status-config.json` to
885 `notmuch-report.json` so it is more obviously associated with the
886 report-generating script. The configuration file also has a new
887 `meta.message-url` setting, which is documented in
888 `notmuch-report.json(5)`.
890 `notmuch-report` now wraps query phrases in parentheses when and-ing
891 them together, to avoid confusion about clause grouping.
893 Notmuch 0.21 (2015-10-29)
894 =========================
899 Notmuch now requires gmime >= 2.6.7. The gmime 2.4 series is no longer
902 Database revision tracking: `lastmod:` queries
904 Each message now has a metadata revision number that increases with
905 every tagging operation. See the discussion of `lastmod:` in
906 `notmuch-search-terms(7)` for more information.
908 Date queries now support `date:<expr>..!` shorthand for
909 `date:<expr>..<expr>`
911 You can use, for example, `date:yesterday..!` to match from the
912 beginning of yesterday to the end of yesterday. For further details,
913 please refer to the `notmuch-search-terms` manual page.
915 Notmuch database upgrade to support `lastmod:` queries
917 The above mentioned `lastmod:` prefix. This will be done
918 automatically, without prompting on the next time `notmuch new` is
919 run after the upgrade. The upgrade is not reversible, and the
920 upgraded database will not be readable by older versions of
921 Notmuch. As a safeguard, a database dump will be created in the
922 `.notmuch` directory before upgrading.
927 The ruby bindings are now built as part of the main notmuch build
928 process. This can be disabled with the `--without-ruby` option to
931 Building the documentation can be disabled with the `--without-docs`
934 Skipped individual tests are no longer considered as failures.
936 Command Line Interface
937 ----------------------
939 Database revision tracking
941 Two new options were added to support revision tracking. A global
942 option "--uuid" (`notmuch(1)`) was added for to detect counter
943 rollover and reinitialization, and `notmuch-count(1)` gained a
944 `--lastmod` option to query database revision tracking data.
946 The `notmuch address` command supports new deduplication schemes
948 `notmuch address` has gained a new `--deduplicate` option to specify
949 how the results should be deduplicated, if at all. The alternatives
950 are `no` (do not deduplicate, useful for processing the results with
951 external tools), `mailbox` (deduplicate based on the full, case
952 sensitive name and email address), and `address` (deduplicate based
953 on the case insensitive address part). See the `notmuch-address`
954 manual page for further information.
959 `notmuch-emacs-version` is used in `User-Agent` header
961 The value of recently introduced variable `notmuch-emacs-version` is
962 now used as a part of `User-Agent` header when sending emails.
964 Removed `notmuch-version` function by renaming it to `notmuch-cli-version`
966 With existing variable `notmuch-emacs-version` the accompanied
967 function which retrieves the version of `notmuch-command` is
968 better named as `notmuch-cli-version`.
970 Query input now supports completion for "is:<tag>"
972 New message composition mode: `notmuch-compose-mode`
974 This is mainly to fix fcc handling, but may be useful for user
975 customization as well.
977 Allow filtering of search results in `notmuch-show`
979 Add function to rerun current tree-view search in search mode
981 Bug fix for replying to encrypted messages in `notmuch-tree` mode
983 Allow saved searched to specify tree view rather than search view
985 Applies to saved searches run from `notmuch-hello`, or by a keyboard
986 shortcut (`notmuch-jump`). Can be set in the customize interface, or
987 by adding :search-type tree to the appropriate saved search plist in
988 `notmuch-saved-searches`.
990 Increase maximum size of rendered text parts
992 The variable `notmuch-show-max-text-part-size` controls the maximum
993 size (in bytes) which is automatically rendered. This may make
994 rendering large threads slower. To get the previous behaviour set
995 this variable to 10000.
1000 The use of absolute paths is now enforced when calling
1001 `notmuch_database_{open, create}`
1003 New function `notmuch_directory_delete` to delete directory documents
1005 Previously there was no way to delete directory documents from the
1006 database, leading to confusing results when the "ghost" directory
1007 document of a renamed or deleted filesystem directory was
1008 encountered every time the parent directory was being scanned by
1009 `notmuch new`. The mtime of the old directory document was also used
1010 if a directory by the same name was added again in the filesystem,
1011 potentially bypassing the scan for the directory. The issues are
1012 fixed by providing a library call to delete directory documents, and
1013 deleting the old documents in `notmuch new` on filesystem directory
1016 Database revision tracking
1018 Revision tracking is supported via a new prefix "lastmod:" in the
1019 query parser and the new function
1020 `notmuch_database_get_revision`. For the latter, see `notmuch(3)`.
1022 New status code returning API for n_query_count_{messages,threads}
1024 Deprecated functions
1026 `notmuch_query_search_threads`, `notmuch_query_search_messages`,
1027 `notmuch_query_count_messages`, and `notmuch_query_count_threads`
1028 are all deprecated as of this release. Clients are encouraged to
1029 transition to the `_st` variants supporting better error reporting.
1034 `nmbug-status` now supports specifying the sort order for each view.
1036 Notmuch 0.20.2 (2015-06-27)
1037 ===========================
1042 Bug fix for marking messages read in `notmuch-tree` mode.
1044 Notmuch 0.20.1 (2015-06-01)
1045 ===========================
1050 Work around apparent gdb bug on arm64.
1052 Notmuch 0.20 (2015-05-31)
1053 =========================
1055 Command-Line Interface
1056 ----------------------
1058 There is a new `mimetype:` search prefix
1060 The new `mimetype:` search prefix allows searching for the
1061 content-type of attachments, which is now indexed. See the
1062 `notmuch-search-terms` manual page for details.
1064 Path to gpg is now configurable
1066 On systems with multiple versions of gpg, you can tell
1067 notmuch which one to use by setting `crypto.gpg_path`
1072 Avoid rendering large text attachments.
1074 Improved rendering of CID references in HTML.
1079 Vim client now respects excluded tags.
1084 Support messages without Message-IDs.
1089 Undeprecate single message mboxes
1091 It seems more trouble to remove this feature than expected, so
1092 `notmuch new` will no longer nag about mboxes with a single message.
1094 New error logging facility
1096 Clients should call `notmuch_database_status_string` to retrieve
1097 output formerly printed to stderr.
1099 Several bug fixes related to stale iterators
1101 New status code returning API for n_query_search_{messages,thread}
1103 Fix for library `install_name` on Mac OS X
1105 Fix for rounding of seconds
1110 Sphinx is now mandatory to build docs
1112 Support for using rst2man in place of sphinx to build the
1113 documentation has been removed.
1115 Improved notmuch-search-terms.7
1117 The man page `notmuch-search-terms(7)` has been extended, merging
1118 some material from the relicensed wiki.
1123 `notmuch-deliver` is removed. As far as we know, all functionality
1124 previously provided by `notmuch-deliver` should now be provided by
1125 `notmuch insert`, provided by the main notmuch binary.
1130 `nmbug-status` now only matches local branches when reading
1131 `status-config.json` from the `config` branch of the `NMBGIT`
1132 repository. To help new users running `nmbug-status`, `nmbug clone`
1133 now creates a local `config` branch tracking `origin/config`. Folks
1134 who use `nmbug-status` with an in-Git config (i.e. you don't use the
1135 `--config` option) who already have `NMBGIT` set up are encouraged to
1138 git checkout config origin/config
1140 in their `NMBGIT` repository (usually `~/.nmbug`).
1142 Notmuch 0.19 (2014-11-14)
1143 =========================
1148 This release improves the reliability of `notmuch dump` and the error
1149 handling for `notmuch insert`. The new `notmuch address` command is
1150 intended to make searching for email addresses more convenient. At the
1151 library level the revised handling of missing messages fixes at least
1152 one bug in threading. The release also includes several interface
1153 improvements to the emacs interface, most notably the ability to bind
1154 keyboard shortcuts to saved searches.
1156 Command-Line Interface
1157 ----------------------
1159 Stopped `notmuch dump` failing if someone writes to the database
1161 The dump command now takes the write lock when running. This
1162 prevents other processes from writing to the database during the
1163 dump which would cause the dump to fail. Note, if another notmuch
1164 process already has the write lock the dump will not start, so
1165 script callers should still check the return value.
1167 `notmuch insert` requires successful message indexing for success status
1169 Previously the `notmuch insert` subcommand indicated success even if
1170 the message indexing failed, as long as the message was delivered to
1171 file system. This could have lead to delivered messages missing
1172 tags, etc. `notmuch insert` is now more strict, also requiring
1173 successful indexing for success status. Use the new `--keep` option
1174 to revert to the old behaviour (keeping the delivered message file
1175 and returning success even if indexing fails).
1177 `notmuch insert` has gained support for `post-insert` hook
1179 The new `post-insert` hook is run after message delivery, similar to
1180 `post-new`. There's also a new option `notmuch insert --no-hooks` to
1181 skip the hook. See the notmuch-hooks(1) man page for details.
1183 `notmuch deliver` is deprecated
1185 With this release we believe that `notmuch insert` has reached
1186 parity with `notmuch deliver`. We recommend that all users of
1187 `notmuch deliver` switch to `notmuch insert` as the former is
1188 currently unmaintained.
1190 `notmuch search` now supports `--duplicate=N` option with `--output=messages`
1192 Complementing the `notmuch search --duplicate=N --output=files`
1193 options, the new `--duplicate=N --output=messages` combination
1194 limits output of message IDs to messages matching search terms that
1195 have at least `N` files associated with them.
1197 Added `notmuch address` subcommand
1199 This new subcommand searches for messages matching the given search
1200 terms, and prints the addresses from them. Duplicate addresses are
1201 filtered out. The `--output` option controls which of the following
1202 information is printed: sender addresses, recipient addresses and
1203 count of duplicate addresses.
1208 Use the `j` key to access saved searches from anywhere in notmuch
1210 `j` is now globally bound to `notmuch-jump`, which provides fast,
1211 interactive keyboard shortcuts to saved searches. For example,
1212 with the default saved searches `j i` from anywhere in notmuch will
1215 Improved handling of the unread tag
1217 Notmuch now marks an open message read (i.e., removes the unread
1218 tag) if point enters the message at any time in a show buffer
1219 regardless of how point got there (mouse click, cursor command, page
1220 up/down, notmuch commands such as n,N etc). This fixes various
1221 anomalies or bugs in the previous handling. Additionally it is
1222 possible to customize the mark read handling by setting
1223 `notmuch-show-mark-read-function` to a custom function.
1225 Expanded default saved search settings
1227 The default saved searches now include several more common searches,
1228 as well as shortcut keys for `notmuch-jump`.
1230 Improved `q` binding in notmuch buffers
1232 `q` will now bury rather than kill a notmuch search, show or tree
1233 buffer if there are multiple windows showing the buffer. If only a
1234 single window is showing the buffer, it is killed.
1236 `notmuch-show-stash-mlarchive-link-alist` now supports functions
1238 Some list archives may use a more complicated scheme for referring
1239 to messages than just concatenated URL and message ID. For example,
1240 patchwork requires a query to translate message ID to a patchwork
1241 patch ID. `notmuch-show-stash-mlarchive-link-alist` now supports
1242 functions to better cover such cases. See the help documentation for
1243 the variable for details.
1248 Introduced database version 3 with support for "database features."
1250 Features are independent aspects of the database schema.
1251 Representing these independently of the database version number will
1252 let us evolve the database format faster and more incrementally,
1253 while maintaining better forwards and backwards compatibility.
1255 Library users are no longer required to call `notmuch_database_upgrade`
1257 Previously, library users were required to call
1258 `notmuch_database_needs_upgrade` and `notmuch_database_upgrade`
1259 before using a writable database. Even the CLI didn't get this
1260 right, and it is no longer required. Now, individual APIs may
1261 return `NOTMUCH_STATUS_UPGRADE_REQUIRED` if the database format is
1262 too out of date for that API.
1264 Library users can now abort an atomic section by closing the database
1266 Previously there was no supported way to abort an atomic section.
1267 Callers can now simply close the database, and any outstanding
1268 atomic section will be aborted.
1270 Add return status to `notmuch_database_close` and
1271 `notmuch_database_destroy`
1273 Bug fixes and performance improvements for thread linking
1275 The database now represents missing-but-referenced messages ("ghost
1276 messages") similarly to how it represents regular messages. This
1277 enables an improved thread linking algorithm that performs better
1278 and fixes a bug that sometimes prevented notmuch from linking
1279 messages into the same thread.
1284 The Perl script has been translated to Python; you'll need Python 2.7
1285 or anything from the 3.x line. Most of the user-facing interface is
1286 the same, but `nmbug help` is now `nmbug --help`, and the following nmbug
1287 commands have slightly different interfaces: `archive`, `commit`,
1288 `fetch`, `log`, `pull`, `push`, and `status`. For details on the
1289 new interface for a given command, run `nmbug COMMAND --help`.
1294 `nmbug-status` can now optionally load header and footer templates
1295 from the config file. Use something like:
1299 "header": "<!DOCTYPE html>\n<html lang="en">\n...",
1300 "footer": "</body></html>",
1309 Add support for `notmuch_query_add_tag_exclude`
1314 The notmuch binaries and libraries are now build with debugging symbols
1315 by default. Users concerned with disk space should change the
1316 defaults when configuring or use the strip(1) command.
1318 Notmuch 0.18.2 (2014-10-25)
1319 ===========================
1324 Translate T380-atomicity to use gdb/python
1326 The new version is compatible with gdb 7.8
1328 Emacs 24.4 related bug fixes
1330 The Messages buffer became read-only, and the generated mime
1331 structure for signatures changed slightly.
1333 Simplify T360-symbol-hiding
1335 Replace the use of `objdump` on the object files with `nm` on the
1338 Notmuch 0.18.1 (2014-06-25)
1339 ===========================
1341 This is a bug fix and portability release.
1346 Add a workaround for systems without zlib.pc
1348 Make emacs install robust against the non-existence of emacs
1350 Put notmuch lib directory first in RPATH
1352 Fix handling of `html_static_path` in sphinx
1354 Both the python bindings and the main docs had spurious settings of
1360 Use --quick when starting emacs
1362 This avoids a hang in the T160-json tests.
1364 Allow pending break points in atomicity script
1366 This allows the atomicity tests to run on several more architectures/OSes.
1368 Command-Line Interface
1369 ----------------------
1371 To improve portability use fsync instead of fdatasync in
1372 `notmuch-dump`. There should be no functional difference.
1377 Resurrect support for single-message mbox files
1379 The removal introduced a bug with previously indexed single-message
1380 mboxes. This support remains deprecated.
1382 Fix for phrase indexing
1384 There were several bugs where words intermingled from different
1385 headers and MIME parts could match a single phrase query. This fix
1386 will affect only newly indexed messages.
1391 Make sure tagging on an empty query is harmless
1393 Previously tagging an empty query could lead to tags being
1394 unintentionally removed.
1396 Notmuch 0.18 (2014-05-06)
1397 =========================
1402 This new release includes some enhancements to searching for messages
1403 by filesystem location (`folder:` and `path:` prefixes under *General*
1404 below). Saved searches in *Emacs* have also been enhanced to allow
1405 distinct search orders for each one. Another enhancement to the
1406 *Emacs* interface is that replies to encrypted messages are now
1407 encrypted, reducing the risk of unintentional information disclosure.
1408 The default dump output format has changed to the more robust
1409 `batch-tag` format. The previously deprecated parsing of single
1410 message mboxes has been removed. For detailed release notes, see
1416 The `folder:` search prefix now requires an exact match
1418 The `folder:` prefix has been changed to search for email messages
1419 by the exact, case sensitive maildir or MH folder name. Wildcard
1420 matching (`folder:foo*`) is no longer supported. The new behaviour
1421 allows for more accurate mail folder based searches, makes it
1422 possible to search for messages in the top-level folder, and should
1423 lead to less surprising results than the old behaviour. Users are
1424 advised to see the `notmuch-search-terms` manual page for details,
1425 and review how the change affects their existing `folder:` searches.
1427 There is a new `path:` search prefix
1429 The new `path:` search prefix complements the `folder:` prefix. The
1430 `path:` prefix searches for email messages that are in particular
1431 directories within the mail store, optionally recursively using a
1432 special syntax. See the `notmuch-search-terms` manual page for
1435 Notmuch database upgrade due to `folder:` and `path:` changes
1437 The above mentioned changes to the `folder:` prefix and the addition
1438 of `path:` prefix require a Notmuch database upgrade. This will be
1439 done automatically, without prompting on the next time `notmuch new`
1440 is run after the upgrade. The upgrade is not reversible, and the
1441 upgraded database will not be readable by older versions of
1442 Notmuch. As a safeguard, a database dump will be created in the
1443 `.notmuch` directory before upgrading.
1448 Notmuch database upgrade
1450 The libnotmuch consumers are reminded to handle database upgrades
1451 properly, either by relying on running `notmuch new`, or checking
1452 `notmuch_database_needs_upgrade()` and calling
1453 `notmuch_database_upgrade()` as necessary. This has always been the
1454 case, but in practise there have been no database upgrades in any
1455 released version of Notmuch before now.
1457 Support for indexing mbox files has been dropped
1459 There has never been proper support for mbox files containing
1460 multiple messages, and the support for single-message mbox files has
1461 been deprecated since Notmuch 0.15. The support has now been
1462 dropped, and all mbox files will be rejected during indexing.
1464 Message header parsing changes
1466 Notmuch previously had an internal parser for message headers. The
1467 parser has now been dropped in favour of letting GMime parse both
1468 the headers and the message MIME structure at the same pass. This is
1469 mostly an internal change, but the GMime parser is stricter in its
1470 interpretation of the headers. This may result in messages with
1471 slightly malformed message headers being now rejected.
1473 Command-Line Interface
1474 ----------------------
1476 `notmuch dump` now defaults to `batch-tag` format
1478 The old format is still available with `--format=sup`.
1480 `notmuch new` has a --quiet option
1482 This option suppresses the progress and summary reports.
1484 `notmuch insert` respects maildir.synchronize_flags config option
1486 Do not synchronize tags to maildir flags in `notmuch insert` if the
1487 user does not want it.
1489 The commands set consistent exit status codes on failures
1491 The cli commands now consistently set exit status of 1 on failures,
1492 except where explicitly otherwise noted. The notable exceptions are
1493 the status codes for format version mismatches for commands that
1494 support formatted output.
1496 Bug fix for checking configured new.tags for invalid tags
1498 `notmuch new` and `notmuch insert` now check the user configured
1499 new.tags for invalid tags, and refuse to apply them, similar to
1500 `notmuch tag`. Invalid tags are currently the empty string and tags
1508 If the file pointed by new variable `notmuch-init-file` (typically
1509 `~/.emacs.d/notmuch-config.el`) exists, it is loaded at the end of
1510 `notmuch.el`. Users can put their personal notmuch emacs lisp based
1511 configuration/customization items there instead of filling
1512 `~/.emacs` with these.
1514 Changed format for saved searches
1516 The format for `notmuch-saved-searches` has changed, but old style
1517 saved searches are still supported. The new style means that a saved
1518 search can store the desired sort order for the search, and it can
1519 store a separate query to use for generating the count notmuch
1522 The variable is fully customizable and any configuration done
1523 through customize should *just work*, with the additional options
1524 mentioned above. For manual customization see the documentation for
1525 `notmuch-saved-searches`.
1527 IMPORTANT: a new style notmuch-saved-searches variable will break
1528 previous versions of notmuch-emacs (even search will not work); to
1529 fix remove the customization for notmuch-saved-searches.
1531 If you have a custom saved search sort function (not unsorted or
1532 alphabetical) then the sort function will need to be
1533 modified. Replacing (car saved-search) by (notmuch-saved-search-get
1534 saved-search :name) and (cdr saved-search) by
1535 (notmuch-saved-search-get saved-search :query) should be sufficient.
1537 The keys of `notmuch-tag-formats` are now regexps
1539 Previously, the keys were literal strings. Customized settings of
1540 `notmuch-tag-formats` will continue to work as before unless tags
1541 contain regexp special characters like `.` or `*`.
1543 Changed tags are now shown in the buffer
1545 Previously tag changes made in a buffer were shown immediately. In
1546 some cases (particularly automatic tag changes like marking read)
1547 this made it hard to see what had happened (e.g., whether the
1548 message had been unread).
1550 The changes are now shown explicitly in the buffer: by default
1551 deleted tags are displayed with red strike-through and added tags
1552 are displayed underlined in green (inverse video is used for deleted
1553 tags if the terminal does not support strike-through).
1555 The variables `notmuch-tag-deleted-formats` and
1556 `notmuch-tag-added-formats`, which have the same syntax as
1557 `notmuch-tag-formats`, allow this to be customized.
1559 Setting `notmuch-tag-deleted-formats` to `'((".*" nil))` and
1560 `notmuch-tag-added-formats` to `'((".*" tag))` will give the old
1561 behavior of hiding deleted tags and showing added tags identically
1562 to tags already present.
1566 The new, build-time generated variable `notmuch-emacs-version` is used
1567 to distinguish between notmuch cli and notmuch emacs versions.
1568 The function `notmuch-hello-versions` (bound to 'v' in notmuch-hello
1569 window) prints both notmuch cli and notmuch emacs versions in case
1570 these differ from each other.
1571 This is especially useful when using notmuch remotely.
1573 Ido-completing-read initialization in Emacs 23
1575 `ido-completing-read` in Emacs 23 versions 1 through 3 freezes unless
1576 it is initialized. Defadvice-based *Ido* initialization is defined
1577 for these Emacs versions.
1579 Bug fix for saved searches with newlines in them
1581 Split lines confuse `notmuch count --batch`, so we remove embedded
1582 newlines before calling notmuch count.
1584 Bug fixes for sender identities
1586 Previously, Emacs would rewrite some sender identities in unexpected
1587 and undesirable ways. Now it will use identities exactly as
1588 configured in `notmuch-identities`.
1590 Replies to encrypted messages will be encrypted by default
1592 In the interest of maintaining confidentiality of communications,
1593 the Notmuch Emacs interface now automatically adds the mml tag to
1594 encrypt replies to encrypted messages. This should make it less
1595 likely to accidentally reply to encrypted messages in plain text.
1597 Reply pushes mark before signature
1599 We push mark and set point on reply so that the user can easily cut
1600 the quoted text. The mark is now pushed before the signature, if
1601 any, instead of end of buffer so the signature is preserved.
1603 Message piping uses the originating buffer's working directory
1605 `notmuch-show-pipe-message` now uses the originating buffer's
1606 current default directory instead of that of the `*notmuch-pipe*`
1612 nmbug adds a `clone` command for setting up the initial repository and
1613 uses `@{upstream}` instead of `FETCH_HEAD` to track upstream changes.
1615 The `@{upstream}` change reduces ambiguity when fetching multiple
1616 branches, but requires existing users update their `NMBGIT`
1617 repository (usually `~/.nmbug`) to distinguish between local and
1618 remote-tracking branches. The easiest way to do this is:
1620 1. If you have any purely local commits (i.e. they aren't in the
1621 nmbug repository on nmbug.tethera.net), push them to a remote
1622 repository. We'll restore them from the backup in step 4.
1623 2. Remove your `NMBGIT` repository (e.g. `mv .nmbug .nmbug.bak`).
1624 3. Use the new `clone` command to create a fresh clone:
1626 nmbug clone https://nmbug.notmuchmail.org/git/nmbug-tags.git
1628 4. If you had local commits in step 1, add a remote for that
1629 repository and fetch them into the new repository.
1631 Notmuch 0.17 (2013-12-30)
1632 =========================
1634 Incompatible change in SHA1 computation
1635 ---------------------------------------
1637 Previously on big endian architectures like sparc and powerpc the
1638 computation of SHA1 hashes was incorrect. This meant that messages
1639 with overlong or missing message-ids were given different computed
1640 message-ids than on more common little endian architectures like i386
1641 and amd64. If you use notmuch on a big endian architecture, you are
1642 strongly advised to make a backup of your tags using `notmuch dump`
1643 before this upgrade. You can locate the affected files using something
1647 awk '/^notmuch-sha1-[0-9a-f]{40} / \
1648 {system("notmuch search --exclude=false --output=files id:" $1)}'
1650 Command-Line Interface
1651 ----------------------
1653 New options to better support handling duplicate messages
1655 If more than one message file is associated with a message-id,
1656 `notmuch search --output=files` will print all of them. A new
1657 `--duplicate=N` option can be used to specify which duplicate to
1658 print for each message.
1660 `notmuch count` now supports `--output=files` option to output the
1661 number of files associated with matching messages. This may be
1662 bigger than the number of matching messages due to duplicates
1663 (i.e. multiple files having the same message-id).
1665 Improved `notmuch new` performance for unchanged folders
1667 `notmuch new` now skips over unchanged folders more efficiently,
1668 which can substantially improve the performance of checking for new
1669 mail in some situations (like NFS-mounted Maildirs).
1671 `notmuch reply --format=text` RFC 2047-encodes headers
1673 Previously, this used a mix of standard MIME encoding for the reply
1674 body and UTF-8 for the headers. Now, the text format reply template
1675 RFC 2047-encodes the headers, making the output a valid RFC 2822
1676 message. The JSON/sexp format is unchanged.
1678 `notmuch compact` command
1680 The new `compact` command exposes Xapian's compaction
1681 functionality through a more convenient interface than
1682 `xapian-compact`. `notmuch compact` will compact the database to a
1683 temporary location, optionally backup the original database, and
1684 move the compacted database into place.
1689 `notmuch-tree` (formerly `notmuch-pick`) has been added to mainline
1691 `notmuch-tree` is a threaded message view for the emacs
1692 interface. Each message is one line in the results and the thread
1693 structure is shown using UTF-8 box drawing characters (similar to
1694 Mutt's threaded view). It comes between search and show in terms of
1695 amount of output and can be useful for viewing both single threads
1696 and multiple threads.
1698 Using `notmuch-tree`
1700 The main key entries to notmuch tree are
1702 'z' enter a query to view using notmuch tree (works in hello,
1703 search, show and tree mode itself)
1705 'Z' view the current query in tree notmuch tree (works from search
1708 Once in tree mode, keybindings are mostly in line with the rest of
1709 notmuch and are all viewable with '?' as usual.
1711 Customising `notmuch-tree`
1713 `notmuch-tree` has several customisation variables. The most
1714 significant is the first notmuch-tree-show-out which determines the
1715 behaviour when selecting a message (with RET) in tree view. By
1716 default tree view uses a split window showing the single message in
1717 the bottom pane. However, if this option is set then it views the
1718 whole thread in the complete window jumping to the selected message
1719 in the thread. In either case command-prefix selects the other option.
1721 Tagging threads in search is now race-free
1723 Previously, adding or removing a tag from a thread in a search
1724 buffer would affect messages that had arrived after the search was
1725 performed, resulting in, for example, archiving messages that were
1726 never seen. Tagging now affects only the messages that were in the
1727 thread when the search was performed.
1729 `notmuch-hello` refreshes when switching to the buffer
1731 The hello buffer now refreshes whenever you switch to the buffer,
1732 regardless of how you get there. You can disable automatic
1733 refreshing by customizing `notmuch-hello-auto-refresh`.
1735 Specific mini-buffer prompts for tagging operations
1737 When entering tags to add or remove, the mini-buffer prompt now
1738 indicates what operation will be performed (e.g., "Tag thread", "Tag
1741 Built-in help improvements
1743 Documentation for many commands has been improved, as displayed by
1744 `notmuch-help` (usually bound to "?"). The bindings listed by
1745 `notmuch-help` also now include descriptions of prefixed commands.
1747 Quote replies as they are displayed in show view
1749 We now render the parts for reply quoting the same way they are
1750 rendered for show. At this time, the notable change is that replies
1751 to text/calendar are now pretty instead of raw vcalendar.
1753 Fixed inconsistent use of configured search order
1755 All ways of interactively invoking search now honor the value of
1756 `notmuch-search-oldest-first`.
1758 Common keymap for notmuch-wide bindings
1760 Several key bindings have been moved from mode-specific keymaps to
1761 the single `notmuch-common-keymap`, which is inherited by each
1762 notmuch mode. If you've customized your key bindings, you may want
1763 to move some of them to the common keymap.
1765 The `notmuch-tag` function now requires a list of tag changes
1767 For users who have scripted the Emacs interface: the `notmuch-tag`
1768 API has changed. Previously, it accepted either a list of tag
1769 changes or a space-separated string of tag changes. The latter is
1770 no longer supported and the function now returns nothing.
1772 Fixed `notmuch-reply` putting reply in primary selection
1774 On emacs 24 notmuch-reply used to put the cited text into the
1775 primary selection (which could lead to inadvertently pasting this
1776 cited text elsewhere). Now the primary-selection is not changed.
1778 Fixed `notmuch-show` invisible part handling
1780 In some obscure cases part buttons and invisibility had strange
1781 interactions: in particular, the default action for some parts gave
1782 the wrong action. This has been fixed.
1784 Fixed `notmuch-show` attachment viewers and stderr
1786 In emacs 24.3+ viewing an attachment could cause spurious text to
1787 appear in the show buffer (any stderr or stdout the viewer
1788 produced). By default this output is now discarded. For debugging,
1789 setting `notmuch-show-attachment-debug` causes notmuch to keep the
1790 viewer's stderr and stdout in a separate buffer.
1792 Fixed `notmuch-mua-reply` point placement when signature involved
1794 By restricting cursor movement to body section for cursor placement
1795 after signature is inserted, the cursor cannot "leak" to header
1796 section anymore. Now inserted citation content will definitely go to
1797 the body part of the message.
1802 It is now possible to compose new messages in the Vim interface, as
1803 opposed reply to existing messages. There is also support for
1804 going straight to a search (bypassing the folders view).
1806 Notmuch 0.16 (2013-08-03)
1807 =========================
1809 Command-Line Interface
1810 ----------------------
1812 Support for delivering messages to Maildir
1814 There is a new command `insert` that adds a message to a Maildir
1815 folder and notmuch index.
1817 `notmuch count --batch` option
1819 `notmuch count` now supports batch operations similar to `notmuch
1820 tag`. This is mostly an optimization for remote notmuch usage.
1822 `notmuch tag` option to remove all tags from matching messages
1824 `notmuch tag --remove-all` option has been added to remove all tags
1825 from matching messages. This can be combined with adding new tags,
1826 resulting in setting (rather than modifying) the tags of the
1829 Decrypting commands explicitly expect a gpg-agent
1831 Decryption in `notmuch show` and `notmuch reply` has only ever
1832 worked with a functioning gpg-agent. This is now made explicit in
1833 code and documentation. The functional change is that it's now
1834 possible to have gpg-agent running, but gpg "use-agent"
1835 configuration option disabled, not forcing the user to use the agent
1838 Configuration file saves follow symbolic links
1840 The notmuch commands that save the configuration file now follow
1841 symbolic links instead of overwrite them.
1843 Top level option to specify configuration file
1845 It's now possible to specify the configuration file to use on the
1846 command line using the `notmuch --config=FILE` option.
1848 Bash command-line completion
1850 The notmuch command-line completion support for the bash shell has
1851 been rewritten. Supported completions include all the notmuch
1852 commands, command-line arguments, values for keyword arguments,
1853 search prefixes (such as "subject:" or "from:") in all commands that
1854 use search terms, tags after + and - in `notmuch tag`, tags after
1855 "tag:" prefix, user's email addresses after "from:" and "to:"
1856 prefixes, and config options (and some config option values) in
1857 `notmuch config`. The new completion support depends on the
1858 bash-completion package.
1860 Deprecated commands "part" and "search-tags" are removed.
1865 New keymap to view/save parts; removed s/v/o/| part button bindings
1867 The commands to view, save, and open MIME parts are now prefixed
1868 with "." (". s" to save, ". v" to view, etc) and can be invoked with
1869 point anywhere in a part, unlike the old commands, which were
1870 restricted to part buttons. The old "s"/"v"/"o"/"|" commands on
1871 part buttons have been removed since they clashed with other
1872 bindings (notably "s" for search!) and could not be invoked when
1873 there was no part button. The new, prefixed bindings appear in
1874 show's help, so you no longer have to memorize them.
1876 Default part save directory is now `mm-default-directory`
1878 Previously, notmuch offered to save parts and attachments to a mix
1879 of `mm-default-directory`, `mailcap-download-directory`, and `~/`.
1880 This has been standardized on `mm-default-directory`.
1882 Key bindings for next/previous thread
1884 Show view has new key bindings M-n and M-p to move to the next and
1885 previous thread in the search results.
1887 Better handling of errors in search buffers
1889 Instead of interleaving errors in search result buffers, search mode
1890 now reports errors in the minibuffer.
1892 Faster search and show
1894 Communication between Emacs and the notmuch CLI is now more
1895 efficient because it uses the CLI's S-expression support. As a
1896 result, search mode should now fill search buffers faster and
1897 threads should show faster.
1901 The Emacs 22 support added late 2010 was sufficient only for a short
1902 period of time. After being incomplete for roughly 2 years the code
1903 in question was now removed from this release.
1908 The vim based front-end has been replaced with a new one that uses the Ruby
1909 bindings. The old font-end is available in the contrib subfolder.
1914 Fix loading of libnotmuch shared library on OS X (Darwin) systems.
1916 Notmuch 0.15.2 (2013-02-17)
1917 ===========================
1922 Update dependencies to avoid problems when building in parallel.
1924 Internal test framework changes
1925 -------------------------------
1927 Adjust Emacs test watchdog mechanism to cope with `process-attributes`
1928 being unimplemented.
1930 Notmuch 0.15.1 (2013-01-24)
1931 ===========================
1933 Internal test framework changes
1934 -------------------------------
1936 Set a default value for TERM when running tests. This fixes certain
1937 build failures in non-interactive environments.
1939 Notmuch 0.15 (2013-01-18)
1940 =========================
1945 Date range search support
1947 The `date:` prefix can now be used in queries to restrict the results
1948 to only messages within a particular time range (based on the Date:
1949 header) with a range syntax of `date:<since>..<until>`. Notmuch
1950 supports a wide variety of expressions in `<since>` and
1951 `<until>`. Please refer to the `notmuch-search-terms(7)` manual page
1954 Empty tag names and tags beginning with "-" are deprecated
1956 Such tags have been a frequent source of confusion and cause
1957 (sometimes unresolvable) conflicts with other syntax. notmuch tag
1958 no longer allows such tags to be added to messages. Removing such
1959 tags continues to be supported to allow cleanup of existing tags,
1960 but may be removed in a future release.
1962 Command-Line Interface
1963 ----------------------
1965 `notmuch new` no longer chokes on mboxes
1967 `notmuch new` now rejects mbox files containing more than one
1968 message, rather than treating the file as one giant message.
1970 Support for single message mboxes is deprecated
1972 For historical reasons, `notmuch new` will index mbox files
1973 containing a single message; however, this behavior is now
1974 officially deprecated.
1976 Fixed `notmuch new` to skip ignored broken symlinks
1978 `notmuch new` now correctly skips symlinks if they are in the
1979 ignored files list. Previously, it would abort when encountering
1980 broken symlink, even if it was ignored.
1982 New dump/restore format and tagging interface
1984 There is a new `batch-tag` format for dump and restore that is more
1985 robust, particularly with respect to tags and message-ids containing
1988 `notmuch tag` now supports the ability to read tag operations and
1989 queries from an input stream, in a format compatible with the new
1990 dump/restore format.
1992 Bcc and Reply-To headers are now available in notmuch show json output
1994 The `notmuch show --format=json` now includes "Bcc" and "Reply-To" headers.
1995 For example notmuch Emacs client can now have these headers visible
1996 when the headers are added to the `notmuch-message-headers` variable.
1998 CLI callers can now request a specific output format version
2000 `notmuch` subcommands that support structured output now support a
2001 `--format-version` argument for requesting a specific version of the
2002 structured output, enabling better compatibility and error handling.
2004 `notmuch search` has gained a null character separated text output format
2006 The new --format=text0 output format for `notmuch search` prints
2007 output separated by null characters rather than newline
2008 characters. This is similar to the find(1) -print0 option, and works
2009 together with the xargs(1) -0 option.
2014 Removal of the deprecated `notmuch-folders` variable
2016 `notmuch-folders` has been deprecated since the introduction of saved
2017 searches and the notmuch hello view in notmuch 0.3. `notmuch-folders`
2018 has now been removed. Any remaining users should migrate to
2019 `notmuch-saved-searches`.
2021 Visibility of MIME parts can be toggled
2023 Each part of a multi-part MIME email can now be shown or hidden
2024 using the button at the top of each part (by pressing RET on it or
2025 by clicking). For emails with multiple alternative formats (e.g.,
2026 plain text and HTML), only the preferred format is shown initially,
2027 but other formats can be shown using their part buttons. To control
2028 the behavior of this, see
2029 `notmuch-multipart/alternative-discouraged` and
2030 `notmuch-show-all-multipart/alternative-parts`.
2032 Note notmuch-show-print-message (bound to '#' by default) will print
2033 all parts of multipart/alternative message regardless of whether
2034 they are currently hidden or shown in the buffer.
2036 Emacs now buttonizes mid: links
2038 mid: links are a standardized way to link to messages by message ID
2039 (see RFC 2392). Emacs now hyperlinks mid: links to the appropriate
2042 Handle errors from bodypart insertions
2044 If displaying the text of a message in show mode causes an error (in
2045 the `notmuch-show-insert-part-*` functions), notmuch no longer cuts
2046 off thread display at the offending message. The error is now
2047 simply displayed in place of the message.
2049 Emacs now detects version mismatches with the notmuch CLI
2051 Emacs now detects and reports when the Emacs interface version and
2052 the notmuch CLI version are incompatible.
2054 Improved text/calendar content handling
2056 Carriage returns in embedded text/calendar content caused insertion
2057 of the calendar content fail. Now CRs are removed before calling icalendar
2058 to extract icalendar data. In case icalendar extraction fails an error
2059 is thrown for the bodypart insertion function to deal with.
2061 Disabled coding conversions when reading in `with-current-notmuch-show-message`
2063 Depending on the user's locale, saving attachments containing 8-bit
2064 data may have performed an unintentional encoding conversion,
2065 corrupting the saved attachment. This has been fixed by making
2066 `with-current-notmuch-show-message` disable coding conversion.
2068 Fixed errors with HTML email containing images in Emacs 24
2070 Emacs 24 ships with a new HTML renderer that produces better output,
2071 but is slightly buggy. We work around a bug that caused it to fail
2072 for HTML email containing images.
2074 Fixed handling of tags with unusual characters in them
2076 Emacs now handles tags containing spaces, quotes, and parenthesis.
2078 Fixed buttonization of id: links without quote characters
2080 Emacs now correctly buttonizes id: links where the message ID is not
2083 `notmuch-hello` refresh point placement improvements
2085 Refreshing the `notmuch-hello` buffer does a better job of keeping
2086 the point where it was.
2088 Automatic tag changes are now unified and customizable
2090 All the automatic tag changes that the Emacs interface makes when
2091 reading, archiving, or replying to messages, can now be
2092 customized. Any number of tag additions and removals is supported
2093 through the `notmuch-show-mark-read`, `notmuch-archive-tags`, and
2094 `notmuch-message-replied-tags` customization variables.
2096 Support for stashing the thread id in show view
2098 Invoking `notmuch-show-stash-message-id` with a prefix argument
2099 stashes the (local and database specific) thread id of the current
2100 thread instead of the message id.
2102 New add-on tool: notmuch-pick
2103 -----------------------------
2105 The new contrib/ tool `notmuch-pick` is an experimental threaded message
2106 view for the emacs interface. Each message is one line in the results
2107 and the thread structure is shown using UTF-8 box drawing characters
2108 (similar to Mutt's threaded view). It comes between search and show in
2109 terms of amount of output and can be useful for viewing both single
2110 threads and multiple threads. See the notmuch-pick README file for
2111 further details and installation.
2116 notmuch now builds on OpenBSD.
2118 Internal test framework changes
2119 -------------------------------
2121 The emacsclient binary is now user-configurable
2123 The test framework now accepts `TEST_EMACSCLIENT` in addition to
2124 `TEST_EMACS` for configuring the emacsclient to use. This is
2125 necessary to avoid using an old emacsclient with a new emacs, which
2126 can result in buggy behavior.
2128 Notmuch 0.14 (2012-08-20)
2129 =========================
2134 Maildir tag synchronization
2136 Maildir flag-to-tag synchronization now applies only to messages in
2137 maildir-like directory structures. Previously, it applied to any
2138 message that had a maildir "info" part, which meant it could
2139 incorrectly synchronize tags for non-maildir messages, while at the
2140 same time failing to synchronize tags for newly received maildir
2141 messages (typically causing new messages to not receive the "unread"
2144 Command-Line Interface
2145 ----------------------
2147 The deprecated positional output file argument to `notmuch dump` has
2148 been replaced with an `--output` option. The input file positional
2149 argument to `notmuch restore` has been replaced with an `--input`
2150 option for consistency with dump. These changes simplify the syntax
2151 of dump/restore options and make them more consistent with other
2157 Search results now get re-colored when tags are updated
2159 The formatting of tags in search results can now be customized
2161 Previously, attempting to change the format of tags in
2162 `notmuch-search-result-format` would usually break tagging from
2163 search-mode. We no longer make assumptions about the format.
2165 Experimental support for multi-line search result formats
2167 It is now possible to embed newlines in
2168 `notmuch-search-result-format` to make individual search results
2169 span multiple lines.
2171 Next/previous in search and show now move by boundaries
2173 All "next" and "previous" commands in the search and show modes now
2174 move to the next/previous result or message boundary. This doesn't
2175 change the behavior of "next", but "previous" commands will first
2176 move to the beginning of the current result or message if point is
2177 inside the result or message.
2179 Search now uses the JSON format internally
2181 This should address problems with unusual characters in authors and
2182 subject lines that could confuse the old text-based search parser.
2184 The date shown in search results is no longer padded before applying
2185 user-specified formatting
2187 Previously, the date in the search results was padded to fixed width
2188 before being formatted with `notmuch-search-result-format`. It is
2189 no longer padded. The default format has been updated, but if
2190 you've customized this variable, you may have to change your date
2191 format from `"%s "` to `"%12s "`.
2193 The thread-id for the `target-thread` argument for `notmuch-search` should
2194 now be supplied without the "thread:" prefix.
2196 Notmuch 0.13.2 (2012-06-02)
2197 ===========================
2202 Update `contrib/notmuch-deliver` for API changes in 0.13. This fixes a
2203 compilation error for this contrib package.
2205 Notmuch 0.13.1 (2012-05-29)
2206 ===========================
2211 Fix inserting of UTF-8 characters from *text/plain* parts in reply
2213 While notmuch gained ability to insert content from other than *text/plain*
2214 parts of email whenever *text/plain* parts are not available (notably
2215 HTML-only emails), replying to mails that do have *text/plain* the
2216 non-ASCII characters were incorrectly decoded. This is now fixed.
2218 `notmuch_database_get_directory` and
2219 `notmuch_database_find_message_by_filename` now work on read-only
2222 Previously, these functions attempted to create directory documents
2223 that didn't exist and would return an error or abort when given a
2224 read-only database. Now they no longer create directory documents
2225 and simply return a `NULL` object if the directory does not exist,
2228 Fix compilation of ruby bindings
2230 Revert to dynamic linking, since the statically linked bindings did
2233 Notmuch 0.13 (2012-05-15)
2234 =========================
2236 Command-Line Interface
2237 ----------------------
2241 `notmuch reply` can now produce JSON output that contains the headers
2242 for a reply message and full information about the original message
2243 begin replied to. This allows MUAs to create replies intelligently.
2244 For example, an MUA that can parse HTML might quote HTML parts.
2246 Calling notmuch reply with `--format=json` imposes the restriction that
2247 only a single message is returned by the search, as replying to
2248 multiple messages does not have a well-defined behavior. The default
2249 retains its current behavior for multiple message replies.
2253 Tags can be automatically excluded from search results by adding them
2254 to the new `search.exclude_tags` option in the Notmuch config file.
2256 This behaviour can be overridden by explicitly including an excluded
2257 tag in your query, for example:
2259 notmuch search $your_query and tag:$excluded_tag
2261 Existing users will probably want to run `notmuch setup` again to add
2262 the new well-commented [search] section to the configuration file.
2264 For new configurations, accepting the default setting will cause the
2265 tags "deleted" and "spam" to be excluded, equivalent to running:
2267 notmuch config set search.exclude_tags deleted spam
2269 Raw show format changes
2271 The output of show `--format=raw` has changed for multipart and
2272 message parts. Previously, the output was a mash of somewhat-parsed
2273 headers and transfer-decoded bodies. Now, such parts are reproduced
2274 faithfully from the original source. Message parts (which includes
2275 part 0) output the full message, including the message headers (but
2276 not the transfer headers). Multipart parts output the part as
2277 encoded in the original message, including the part's headers. Leaf
2278 parts, as before, output the part's transfer-decoded body.
2280 Listing configuration items
2282 The new `config list` command prints out all configuration items and
2288 Changes to tagging interface
2290 The user-facing tagging functions in the Emacs interface have been
2291 normalized across all notmuch modes. The tagging functions are now
2292 notmuch-search-tag in search-mode, and notmuch-show-tag in
2293 show-mode. They accept a string representing a single tag change,
2294 or a list of tag changes. See 'M-x describe-function notmuch-tag'
2295 for more information.
2297 NOTE: This breaks compatibility with old tagging functions, so user
2298 may need to update in custom configurations.
2300 Reply improvement using the JSON format
2302 Emacs now uses the JSON reply format to create replies. It obeys
2303 the customization variables message-citation-line-format and
2304 message-citation-line-function when creating the first line of the
2305 reply body, and it will quote HTML parts if no text/plain parts are
2308 New add-on tool: notmuch-mutt
2309 -----------------------------
2311 The new contrib/ tool `notmuch-mutt` provides Notmuch integration for
2312 the Mutt mail user agent. Using it, Mutt users can perform mail
2313 search, thread reconstruction, and mail tagging/untagging without
2314 leaving Mutt. notmuch-mutt, formerly distributed under the name
2315 `mutt-notmuch` by Stefano Zacchiroli, will be maintained as a notmuch
2316 contrib/ from now on.
2321 The API changes detailed below break binary and source compatibility,
2322 so libnotmuch has been bumped to version 3.0.0.
2324 The function `notmuch_database_close` has been split into
2325 `notmuch_database_close` and `notmuch_database_destroy`
2327 This makes it possible for long running programs to close the xapian
2328 database and thus release the lock associated with it without
2329 destroying the data structures obtained from it.
2331 `notmuch_database_open`, `notmuch_database_create`, and
2332 `notmuch_database_get_directory` now return errors
2334 The type signatures of these functions have changed so that the
2335 functions now return a `notmuch_status_t` and take an out-argument for
2336 returning the new database object or directory object.
2343 The go bindings and the `notmuch-addrlookup` utility are now
2344 compatible with go 1.
2346 Notmuch 0.12 (2012-03-20)
2347 =========================
2349 Command-Line Interface
2350 ----------------------
2354 `notmuch reply` has gained the ability to create a reply template
2355 for replying just to the sender of the message, in addition to reply
2356 to all. The feature is available through the new command line option
2357 `--reply-to=(all|sender)`.
2359 Mail store folder/file ignore
2361 A new configuration option, `new.ignore`, lets users specify a
2362 ;-separated list of file and directory names that will not be
2363 searched for messages by `notmuch new`.
2365 NOTE: *Every* file/directory that goes by one of those names will
2366 be ignored, independent of its depth/location in the mail store.
2368 Unified help and manual pages
2370 The notmuch help command now runs man for the appropriate page. If
2371 you install notmuch somewhere "unusual", you may need to update
2374 Manual page for notmuch configuration options
2376 The notmuch CLI configuration file options are now documented in the
2377 notmuch-config(1) manual page in addition to the configuration file
2385 The Emacs interface has, with the new CLI support, gained the
2386 ability to reply to sender in addition to reply to all. In both show
2387 and search modes, 'r' has been bound to reply to sender, replacing
2388 reply to all, which now has key binding 'R'.
2390 More flexible and consistent tagging operations
2392 All tagging operations ('+', '-', '*') now accept multiple tags with
2393 '+' or '-' prefix, like '*' operation in notmuch-search view before.
2395 '*' operation (`notmuch-show-tag-all`) is now available in
2398 `notmuch-show-{add,remove}-tag` functions no longer accept tag
2399 argument, `notmuch-show-tag-message` should be used instead. Custom
2400 bindings using these functions should be updated, e.g.:
2402 (notmuch-show-remove-tag "unread")
2404 should be changed to:
2406 (notmuch-show-tag-message "-unread")
2408 Refreshing the show view ('=' by default) no longer opens or closes messages
2410 To get the old behavior of putting messages back in their initial
2411 opened/closed state, use a prefix argument, e.g., 'C-u ='.
2413 Attachment buttons can be used to view or save attachments.
2415 When the cursor is on an attachment button the key 's' can be used
2416 to save the attachment, the key 'v' to view the attachment in the
2417 default mailcap application, and the key 'o' prompts the user for an
2418 application to use to open the attachment. By default Enter or mouse
2419 button 1 saves the attachment but this is customisable (option
2420 Notmuch Show Part Button Default Action).
2424 `notmuch-show-stash-mlarchive-link{,-and-go}` allow stashing and
2425 optionally visiting a URI to the current message at one of a number
2426 of Mailing List Archives.
2428 Fix MML tag quoting in replies
2430 The MML tag quoting fix of 0.11.1 unintentionally quoted tags
2431 inserted in `message-setup-hook`. Quoting is now limited to the
2434 Show view archiving key binding changes
2436 The show view archiving key bindings 'a' and 'x' now remove the
2437 "inbox" tag from the current message only (instead of thread), and
2438 move to the next message. At the last message, 'a' proceeds to the
2439 next thread in search results, and 'x' returns to search
2440 results. The thread archiving functions are now available in 'A' and
2443 Support text/calendar MIME type
2445 The text/calendar MIME type is now supported in addition to
2448 Generate inline patch fake attachment file names from message subject
2450 Use the message subject to generate file names for the inline patch
2451 fake attachments. The names are now similar to the ones generated by
2452 'git format-patch' instead of just "inline patch". See "Notmuch Show
2453 Insert Text/Plain Hook" in the notmuch customize interface.
2455 Enable `notmuch-search-line-faces` by default
2457 Make the `notmuch-search-line-faces` functionality more discoverable
2458 for new users by showing "unread" messages bold and "flagged"
2459 messages blue by default in the search view.
2463 notmuch-show mode now has simple printing support, bound to '#' by
2464 default. You can customize the variable notmuch-print-mechanism.
2471 `notmuch_query_add_tag_exclude` supports the new tag exclusion
2474 Python bindings changes
2475 -----------------------
2477 Python 3.2 compatibility
2479 The python bindings are now compatible with both python 2.5+ and 3.2.
2481 Added missing unicode conversions
2483 Python strings have to be encoded to and decoded from utf-8 when
2484 calling libnotmuch functions. Porting the bindings to python 3.2
2485 revealed a few function calls that were missing these conversions.
2490 Compatibility with GMime 2.6
2492 It is now possible to build notmuch against both GMime 2.4 and 2.6.
2493 However, a bug in GMime 2.6 before 2.6.5 causes notmuch not to
2494 report signatures where the signer key is unavailable (GNOME bug
2495 668085). For compatibility with GMime 2.4's tolerance of "From "
2496 headers we require GMime 2.6 >= 2.6.7.
2498 Notmuch 0.11.1 (2012-02-03)
2499 ===========================
2504 Fix error handling in python bindings
2506 The python bindings in 0.11 failed to detect NULL pointers being
2507 returned from libnotmuch functions and thus failed to raise
2508 exceptions to indicate the error condition. Any subsequent calls
2509 into libnotmuch caused segmentation faults.
2511 Quote MML tags in replies
2513 MML tags are text codes that Emacs uses to indicate attachments
2514 (among other things) in messages being composed. The Emacs
2515 interface did not quote MML tags in the quoted text of a reply.
2516 User could be tricked into replying to a maliciously formatted
2517 message and not editing out the MML tags from the quoted text. This
2518 could lead to files from the user's machine being attached to the
2519 outgoing message. The Emacs interface now quotes these tags in
2520 reply text, so that they do not effect outgoing messages.
2522 Notmuch 0.11 (2012-01-13)
2523 =========================
2525 Command-Line Interface
2526 ----------------------
2530 Hooks have been introduced to notmuch. Hooks are scripts that notmuch
2531 invokes before and after certain actions. Initially, `notmuch new`
2532 supports `pre-new` and `post-new` hooks that are run before and after
2533 importing new messages into the database.
2535 `notmuch reply --decrypt bugfix`
2537 The `notmuch reply` command with `--decrypt` argument had a rarely
2538 occurring bug that caused an encrypted message not to be decrypted
2539 sometimes. This is now fixed.
2544 Automatic tag query optimization
2546 `notmuch tag` now automatically optimizes the user's query to
2547 exclude messages whose tags won't change. In the past, we've
2548 suggested that people do this by hand; this is no longer necessary.
2550 Don't sort messages when creating a dump file
2552 This speeds up tag dumps considerably, without any loss of
2553 information. To replicate the old behavior of sorted output (for
2554 example to compare two dump files), one can use e.g. `sort(1)`.
2559 Reduction of memory leaks
2561 Two memory leaks when searching and showing messages were identified
2562 and fixed in this release.
2569 notmuch-show-advance (bound to the spacebar in notmuch-show-mode) had
2570 a bug that caused it to always jump to the next message, even if it
2571 should have scrolled down to show more of the current message instead.
2574 Support `notmuch new` as a notmuch-poll-script
2576 It's now possible to use `notmuch new` as a notmuch-poll-script
2577 directly. This is also the new default. This allows taking better
2578 advantage of the `notmuch new` hooks from emacs without intermediate
2581 Improvements in saved search management
2583 New saved searches are now appended to the list of saved searches,
2584 not inserted in front. It's also possible to define a sort function
2585 for displaying saved searches; alphabetical sort is provided.
2587 Hooks for notmuch-hello
2589 Two new hooks have been added: "notmuch-hello-mode-hook" (called after
2590 entering notmuch-hello-mode) and "notmuch-hello-refresh-hook" (called
2591 after updating a notmuch-hello buffer).
2593 New face for crypto parts headers
2595 Crypto parts used to be displayed with a hardcoded color. A new face
2596 has been introduced to fix this: notmuch-crypto-part-header. It
2597 defaults to the same value as before, but can be customized to match
2600 Use space as default thousands separator
2602 Large numbers in notmuch-hello are now displayed using a space as
2603 thousands separator (e.g. "123 456" instead of "123,456"). This can be
2604 changed by customizing "notmuch-hello-thousands-separator".
2606 Call notmuch-show instead of notmuch-search when clicking on
2607 buttonized id: links
2609 New function notmuch-show-advance
2611 This new function advances through just the current thread, and is
2612 less invasive than notmuch-show-advance-and-archive. It can easily
2613 be bound to SPC with:
2615 (define-key notmuch-show-mode-map " " 'notmuch-show-advance)
2617 Various performance improvements
2622 The tool `contrib/notmuch-deliver` helps with initial delivery and
2623 tagging of mail (replacing running `notmuch new`).
2626 Notmuch 0.10.2 (2011-12-04)
2627 ===========================
2632 Fix crash in python bindings
2634 The python bindings did not call `g_type_init`, which caused crashes
2635 for some, but not all users.
2637 Notmuch 0.10.1 (2011-11-25)
2638 ===========================
2643 Fix `--help` argument
2645 Argument processing changes in 0.10 introduced a bug where
2646 `notmuch --help` crashed while `notmuch help` worked fine.
2647 This is fixed in 0.10.1.
2649 Notmuch 0.10 (2011-11-23)
2650 =========================
2652 New build and testing features
2653 ------------------------------
2655 Emacs tests are now done in `dtach`. This means that dtach is now
2656 needed to run the notmuch test suite, at least until the checking for
2657 prerequisites is improved.
2659 Full test coverage of the stashing feature in Emacs.
2661 New command-line features
2662 -------------------------
2664 Add `notmuch restore --accumulate` option
2666 The `--accumulate` switch causes the union of the existing and new tags to
2667 be applied, instead of replacing each message's tags as they are read in
2670 Add search terms to `notmuch dump`
2672 The dump command now takes an optional search term much like notmuch
2673 search/show/tag. The output file argument of dump is deprecated in
2674 favour of using stdout.
2676 Add `notmuch search` `--offset` and `--limit` options
2678 The search command now takes options `--offset=[-]N` and `--limit=N` to
2679 limit the number of results shown.
2681 Add `notmuch count --output` option
2683 The count command is now capable of counting threads in addition to
2684 messages. This is selected using the new `--output=(threads|messages)`
2687 New emacs UI features
2688 ---------------------
2690 Add tab-completion for `notmuch-search` and `notmuch-search-filter`
2692 These functions now support completion tags for query parts
2693 starting with "tag:".
2695 Turn "id:MSG-ID" links into buttons associated with notmuch searches
2697 Text of the form "id:MSG-ID" in mails is now a clickable button that
2698 opens a notmuch search for the given message id.
2700 Add keybinding ('c I') for stashing Message-ID's without an id: prefix
2702 Reduces manual labor when stashing them for use outside notmuch.
2704 Do not query on `notmuch-search` exit
2706 It is harmless to kill the external notmuch process, so the user
2707 is no longer interrogated when they interrupt a search.
2712 Emacs now constructs large search buffers more efficiently
2714 Search avoids opening and parsing message files
2716 We now store more information in the database so search no longer
2717 has to open every message file to get basic headers. This can
2718 improve search speed by as much as 10X, but taking advantage of this
2719 requires a database rebuild:
2721 notmuch dump > notmuch.dump
2722 # Backup, then remove notmuch database ($MAIL/.notmuch)
2724 notmuch restore notmuch.dump
2726 New collection of add-on tools
2727 ------------------------------
2729 The source directory "contrib" contains tools built on notmuch. These
2730 tools are not part of notmuch, and you should check their individual
2731 licenses. Feel free to report problems with them to the notmuch
2734 nmbug - share tags with a given prefix
2736 nmbug helps maintain a git repo containing all tags with a given
2737 prefix (by default "notmuch::"). Tags can be shared by committing
2738 them to git in one location and restoring in another.
2740 Notmuch 0.9 (2011-10-01)
2741 ========================
2743 New, general features
2744 ---------------------
2746 Correct handling of interruptions during `notmuch new`
2748 `notmuch new` now operates as a series of small, self-consistent
2749 transactions, so it can correctly resume after an interruption or
2750 crash. Previously, interruption could lose existing tags, fail to
2751 detect messages on resume, or leave the database in a state
2752 temporarily or permanently inconsistent with the mail store.
2759 `notmuch_database_begin_atomic` and `notmuch_database_end_atomic`
2760 allow multiple database operations to be performed atomically.
2762 `notmuch_database_find_message_by_filename` does exactly what it says.
2766 `notmuch_database_find_message` (and `n_d_f_m_by_filename`) now return
2767 a status indicator and uses an output parameter for the
2768 message. This change required changing the SONAME of libnotmuch to
2771 Python bindings changes
2772 -----------------------
2774 - Re-encode python unicode objects to utf-8 before passing back to
2776 - Support `Database().begin_atomic()/end_atomic()`
2777 - Support `Database().find_message_by_filename()`
2778 NB! This needs a db opened in READ-WRITE mode currently, or it will crash
2779 the python process. The is a limitation (=bug) of the underlying libnotmuch.
2780 - Fixes where we would not throw NotmuchErrors when we should (Justus Winter)
2781 - Update for `n_d_find_message*` API changes (see above).
2783 Ruby bindings changes
2784 ---------------------
2786 - Wrap new library functions `notmuch_database_{begin,end}_atomic.`
2787 - Add new exception `Notmuch::UnbalancedAtomicError.`
2788 - Rename destroy to destroy! according to Ruby naming conventions.
2789 - Update for `n_d_find_message*` API changes (see above).
2794 * Add gpg callback to crypto sigstatus buttons to retrieve/refresh
2796 * Add `notmuch-show-refresh-view` function (and corresponding binding)
2797 to refresh the view of a notmuch-show buffer.
2799 Reply formatting cleanup
2800 ------------------------
2802 `notmuch reply` no longer includes notification that non-leafnode
2803 MIME parts are being suppressed.
2805 Notmuch 0.8 (2011-09-10)
2806 ========================
2808 Improved handling of message/rfc822 parts
2810 Both in the CLI and the emacs interface. Output of rfc822 parts now
2811 includes the primary headers, as well as the body and all subparts.
2812 Output of the completely raw rfc822-formatted message, including all
2813 headers, is unfortunately not yet supported (but hopefully will be
2816 Improved Build system portability
2818 Certain parts of the shell script generating notmuch.sym were
2819 specific to the GNU versions of sed and nm. The new version should
2820 be more portable to e.g. OpenBSD.
2822 Documentation update for Ruby bindings
2824 Added documentation, typo fixes, and improved support for rdoc.
2826 Unicode, iterator, PEP8 changes for python bindings
2828 - PEP8 (code formatting) changes for python files.
2829 - Remove `Tags.__len__` ; see 0.6 release notes for motivation.
2830 - Decode headers as UTF8, encode (unicode) database paths as UTF8.
2832 Notmuch 0.7 (2011-08-01)
2833 ========================
2835 Vim interface improvements
2836 --------------------------
2838 Jason Woofenden provided a number of bug fixes for the Vim interface
2840 * fix citation/signature fold lengths
2841 * fix cig/cit parsing within multipart/*
2842 * fix on-screen instructions for show-signature
2843 * fix from list reformatting in search view
2844 * fix space key: now archives (did opposite)
2846 Uwe Kleine-König contributed
2848 * use full path for sendmail/doc fix
2849 * fix compose temp file name
2851 Python Bindings changes
2852 -----------------------
2854 Sebastian Spaeth contributed two changes related to unicode and UTF8:
2856 * message tags are now explicitly unicode
2857 * query string is encoded as a UTF8 byte string
2859 Build-System improvements
2860 -------------------------
2862 Generate notmuch.sym after the relevant object files
2864 This fixes a bug in parallel building. Thanks to Thomas Jost for the
2867 Notmuch 0.6.1 (2011-07-17)
2868 ==========================
2873 Re-export Xapian exception typeinfo symbols
2875 It turned out our aggressive symbol hiding caused problems for
2876 people running gcc 4.4.5.
2878 Notmuch 0.6 (2011-07-01)
2879 =======================
2881 New, general features
2882 ---------------------
2884 Folder-based searching
2886 Notmuch queries can now include a search term to match the
2887 directories in which mail files are stored (within the mail
2888 storage). The syntax is as follows:
2892 For example, one might use things such as:
2898 to match any path containing a directory "spam", "work/todo", or
2899 containing a directory starting with "2011-", respectively.
2901 This feature is particularly useful for users of delivery-agent
2902 software (such as procmail or maildrop) that is filtering mail and
2903 delivering it to particular folders, or users of systems such as
2904 Gmail that use filesystem directories to indicate message tags.
2906 NOTE: Only messages that are newly indexed with this version of
2907 notmuch will be searchable with folder: terms. In order to enable
2908 this feature for all mail, the entire notmuch index will need to be
2911 notmuch dump > notmuch.dump
2912 # Backup, then remove notmuch database ($MAIL/.notmuch)
2914 notmuch restore notmuch.dump
2916 Support for PGP/MIME
2918 Both the command-line interface and the emacs-interface have new
2919 support for PGP/MIME, detailed below. Thanks to Daniel Kahn Gillmor
2920 and Jameson Graef Rollins for making this happen.
2922 New, automatic tags: "signed" and "encrypted"
2924 These tags will automatically be applied to messages containing
2925 multipart/signed and multipart/encrypted parts.
2927 NOTE: Only messages that are newly indexed with this version of
2928 notmuch will receive these tags.
2930 New command-line features
2931 -------------------------
2933 Add new "notmuch show --verify" option for signature verification
2935 This option instruct notmuch to verify the signature of
2936 PGP/MIME-signed parts.
2938 Add new "notmuch show --decrypt" and "notmuch reply --decrypt" options
2940 This option instructs notmuch to decrypt PGP/MIME-encrypted parts.
2941 Note that this feature currently requires gpg-agent and a passphrase entry
2942 tool (e.g. pinentry-gtk or pinentry-curses).
2944 Proper nesting of multipart parts in "notmuch show" output
2946 MIME parts are now display with proper nesting to reflect original
2947 MIME hierarchy of a message. This allows clients to correctly
2948 analyze the MIME structure, (such as, for example, determining to
2949 which parts a signature part applies).
2951 Add new "notmuch show --part" option
2953 This is a replacement for the older "notmuch part" command, (which
2954 is now deprecated—it should still work as always, but is no longer
2955 documented). Putting part output under "notmuch show" allows for all
2956 of the "notmuch show" options to be applied when extracting a single
2957 part, (such as --format=json for extracting a message part with JSON
2960 Deprecate "notmuch search-tags" (in favor of "notmuch search --output=tags *")
2962 The "notmuch search-tags" sub-command has been redundant since the
2963 addition of the --output=tags option to "notmuch search". We now
2964 make that more clear by deprecating "notmuch search-tags", (dropping
2965 it from the documentation). We do continue to support the old syntax
2966 by translating it internally to the new call.
2968 Performance improvements
2969 ------------------------
2971 Faster searches (by doing fewer searches to construct threads)
2973 Whenever a user asks for search results as threads, notmuch first
2974 performs a search for messages matching the query, then performs
2975 additional searches to find other messages in the resulting threads.
2977 Removing inefficiencies and redundancies in these secondary searches
2978 results in a measured speedups of 1.5x for a typical search.
2980 Faster searches (by doing fewer passes to gather message data)
2982 Optimizing Xapian data access patterns (using a single pass to get
2983 all message-document data rather than a pass for each data type)
2984 results in a measured speedup of 1.7x for a typical search.
2986 The benefits of this optimization combine with the preceding
2987 optimization. With both in place, Austin Clements measured a speedup
2988 of 2.5x for a search of all messages in his inbox (was 4.5s, now
2989 1.8s). Thanks, Austin!
2991 Faster initial indexing
2993 More efficient indexing of new messages results in a measured
2994 speedup of 1.4x for the initial indexing of 3 GB of mail (1h 14m
2995 rather than 1h 46m). Thanks to Austin Clements and Michal Sojka.
2997 Make "notmuch new" faster for unchanged directories
2999 Optimizing to not do any further examinations of sub-directories
3000 when the filesystem indicates that a directory is unchanged from the
3001 last "notmuch new" results in measured speedups of 8.5 for the "No
3002 new mail" case, (was 0.77s, now 0.09s). Thanks to Karel Zak.
3004 New emacs-interface features
3005 ----------------------------
3007 Support for PGP/MIME (GnuPG)
3009 Automatically indicate validity of signatures for multipart/signed
3010 messages. Automatically display decrypted content for
3011 multipart/encrypted messages. See the emacs variable
3012 notmuch-crypto-process-mime for more information. Note that this
3013 needs gpg-agent and a pinentry tool just as the command-line tools.
3014 Also note there is no support SMIME yet.
3016 Output of pipe command is now displayed if pipe command fails
3018 This is extremely useful in the common use case of piping a patch to
3019 "git am". If git fails to cleanly merge the patch the error messages
3020 from the failed merge are now clearly displayed to the user, (where
3021 previously they were silently hidden from the user).
3023 User-selectable From address
3025 A user can choose which configured email addresses should be used as
3026 the From address whenever composing a new message. To do so, simply
3027 press C-u before the command which will open a new message. Emacs
3028 will prompt for the from address to use.
3030 The user can customize the "Notmuch Identities" setting in the
3031 notmuch customize group in order to use addresses other than those in
3032 the notmuch configuration file if desired.
3034 The user can also choose to always be prompted for the from address
3035 when composing a new message (without having to use C-u) by setting
3036 the "Notmuch Always Prompt For Sender" option in the notmuch
3039 Hiding of repeated subjects in collapsed thread view
3041 In notmuch-show mode, if a collapsed message has the same subject as
3042 its parent, the subject is not shown.
3044 Automatic detection and hiding of original message in top-posted message
3046 When a message contains a line looking something like:
3048 ----- Original Message -----
3050 emacs hides this and all subsequent lines as an "original message",
3051 (allowing the user to click or press enter on the "original message"
3052 button to display it again). This makes the handling of top-posted
3053 citations work much like conventional citations.
3055 New hooks for running code when tags are modified
3057 Some users want to perform additional actions whenever a particular
3058 tag is added/removed from a message. This could be used to, for
3059 example, interface with some external spam-recognition training
3060 tool. To facilitate this, two new hooks are added which can be
3061 modified in the following settings of the notmuch customize group:
3063 Notmuch Before Tag Hook
3064 Notmuch After Tag Hook
3066 New optional support for hiding some multipart/alternative parts
3068 Many emails are sent with redundant content within a
3069 multipart/alternative group (such as a text/plain part as well as a
3070 text/html part). Users can configure the setting:
3072 Notmuch Show All Multipart/Alternative Parts
3074 to "off" in the notmuch customize group to have the interface
3075 automatically hide some part alternatives (such as text/html
3076 parts). This new part hiding is not configured by default yet
3077 because there's not yet a simple way to re-display such a hidden
3078 part if it is not actually redundant with a displayed part.
3080 Better rendering of text/x-vcalendar parts
3082 These parts are now displayed in a format suitable for use with the
3085 Avoid getting confused by Subject and Author fields with newline characters
3087 Replacing all characters with ASCII code less than 32 with a question mark.
3089 Cleaner display of From line in email messages
3091 Remove double quotes, and drop "name" if it's actually just a repeat of
3094 Vim interface improvements
3095 --------------------------
3097 Felipe Contreras provided a number of updates for the vim interface:
3099 * Using sendmail directly rather than mailx,
3100 * Implementing archive in show view
3101 * Add support to mark as read in show and search views
3102 * Add delete commands
3105 Bindings improvements
3106 ---------------------
3108 Ruby bindings are now much more complete
3110 Including `QUERY.sort`, `QUERY.to_s`, `MESSAGE.maildir_flags_to_tags`,
3111 `MESSAGE.tags_to_maildir_flags`, and `MESSAGE.get_filenames`
3113 Python bindings have been updated and extended
3115 (docs online at https://notmuch.readthedocs.io/)
3119 - `Message().get_filenames()`, `Message().tags_to_maildir_flags()`,
3120 `Message().maildir_flags_to_tags()`, `list(Threads())` and
3121 `list(Messages)` works now
3122 - `Message().__cmp__()` and `__hash__()`
3124 These allow, for example:
3126 if msg1 == msg2: ...
3128 As well as set arithmetic on `Messages()`:
3130 s1, s2 = set(msgs1), set(msgs2)
3136 - `len(Messages())` as it exhausted the iterator
3138 Use `len(list(Messages()))` or `Query.count_messages()`
3141 Added initial Go bindings in bindings/go
3143 New build-system features
3144 -------------------------
3146 Added support for building in a directory other than the source directory
3148 This can be used with the widely-supported idiom of simply running
3149 the configure script from some other directory:
3156 Fix to save configure options for future, implicit runs of configure
3158 When a user updates the source (such as with "git pull") calling
3159 "make" may cause an automatic re-run of the configure script. When
3160 this happens, the configure script will automatically be called with
3161 the same options the user originally passed in the most-recent
3162 manual invocation of configure.
3164 New test-suite feature
3165 ----------------------
3167 Binary for bash for running test suite now located via PATH
3169 The notmuch test suite requires a fairly recent version of bash (>=
3170 bash 4). As some systems supply an older version of bash at
3171 /bin/bash, the test suite is now updated to search $PATH to locate
3172 the bash binary. This allows users of systems with old /bin/bash to
3173 simply install bash >= 4 somewhere on $PATH before /bin and then use
3176 Support for testing output with a trailing newline
3178 Previously, some tests would fail to notice a difference in the
3179 presence/absence of a trailing newline in a program output, (which
3180 has led to bugs in the past). Now, carefully-written tests (using
3181 `test_expect_equal_file` rather than `test_expect_equal`) will detect
3182 any change in the presence/absence of a trailing newline. Many tests
3183 are updated to take advantage of this.
3185 Avoiding accessing user's $HOME while running test suite
3187 The test suite now carefully creates its own HOME directory. This
3188 allows the test suite to be run with no existing HOME directory, (as
3189 some build systems apparently do), and avoids test-suite differences
3190 due to configuration files in the users HOME directory.
3196 Output *all* files for "notmuch search --output=files"
3198 For the cases where multiple files have the same Message ID,
3199 previous versions of notmuch would output only one such file. This
3200 command is now fixed to correctly output all files.
3202 Fixed spurious search results from "overlapped" indexing of addresses
3204 This fixed a bug where a search for:
3206 to:user@elsewhere.com
3208 would incorrectly match a message sent:
3210 To: user@example,com, someone@elsewhere.com
3212 Fix --output=json when search has no results
3214 A bug present since notmuch 0.4 had caused searches with no results
3215 to produce an invalid json object. This is now fixed to cleanly
3216 return a valid json object representing an empty array "[]" as
3219 Fix the automatic detection of the From address for "notmuch reply"
3220 from the Received headers in some cases
3222 Fix core dump on DragonFlyBSD due to -1 return value from
3223 `sysconf(_SC_GETPW_R_SIZE_MAX)`
3225 Cleaned up several memory leaks
3227 Eliminated a few, rare segmentation faults and a double-free
3229 Fix libnotmuch library to only export notmuch API functions
3231 Previous release of the notmuch library also exported some Xapian
3232 C++ exception type symbols. These were never part of the library
3233 interface and were never intended to be exported.
3235 Emacs-interface bug fixes
3236 -------------------------
3238 Display any unexpected output or errors from "notmuch search" invocations
3240 Previously any misformatted output or trailing error messages were
3241 silently ignored. This output is now clearly displayed. This fix was
3242 very helpful in identifying and fixing the bug described below.
3244 Fix bug where some threads would be missing from large search results
3246 When a search returned a "large" number of results, the emacs
3247 interface was incorrectly dropping one thread every time the output
3248 of the "notmuch search" process spanned the emacs read-buffer. This
3251 Avoid re-compression of .gz files (and similar) when saving attachment
3253 Emacs was being too clever for its own good and trying to
3254 re-compress pre-compressed .gz files when saving such attachments
3255 (potentially corrupting the attachment). The emacs interface is
3256 fixed to avoid this bug.
3258 Fix hiding of a message when a previously-hidden citation is visible
3260 Previously the citation would remain visible in this case. This is
3261 fixed so that hiding a message hides all parts.
3263 Notmuch 0.5 (2010-11-11)
3264 ========================
3266 New, general features
3267 ---------------------
3269 Maildir-flag synchronization
3271 Notmuch now knows how to synchronize flags in maildir filenames with
3272 tags in the notmuch database. The following flag/tag mappings are
3281 'S' unread (added when 'S' flag is not present)
3283 The synchronization occurs in both directions, (for example, adding
3284 the 'S' flag to a file will cause the "unread" tag to be added, and
3285 adding the "replied" tag to a message will cause the file to be
3286 renamed with an 'R' flag).
3288 This synchronization is enabled by default for users of the
3289 command-line interface, (though only files in directories named
3290 "cur" or "new" will be renamed). It can be disabled by setting the
3291 new `maildir.synchronize_flags` option in the configuration file. For
3294 notmuch config set maildir.synchronize_flags false
3296 Users upgrading may also want to run "notmuch setup" once (just
3297 accept the existing configuration) to get a new, nicely-commented
3298 [maildir] section added to the configuration file.
3300 For users of the notmuch library, the new synchronization
3301 functionality is available with the following two new functions:
3303 notmuch_message_maildir_flags_to_tags
3304 notmuch_message_tags_to_maildir_flags
3306 It is anticipated that future improvements to this support will
3307 allow for safe synchronization of the 'T' flag with the "deleted"
3308 tag, as well as support for custom flag/tag mappings.
3310 New library features
3311 --------------------
3313 Support for querying multiple filenames for a single message
3315 It is common for the mailstore to contain multiple files with the
3316 same message ID. Previously, notmuch would always hide these
3317 duplicate files, (returning a single, arbitrary filename with
3318 `notmuch_message_get_filename`).
3320 With this release, library users can access all filenames for a
3321 message with the new function:
3323 notmuch_message_get_filenames
3325 Together with `notmuch_filenames_valid`, `notmuch_filenames_get`,
3326 and `notmuch_filenames_move_to_next` it is now possible to iterate
3327 over all available filenames for a given message.
3329 New command-line features
3330 -------------------------
3332 New "notmuch show --format=raw" for getting at original email contents
3334 This new feature allows for a fully-functional email client to be
3335 built on top of the notmuch command-line without needing any direct
3336 access to the mail store itself.
3338 For example, it's now possible to run "emacs -f notmuch" on a local
3339 machine with only ssh access to the mail store/notmuch database. To
3340 do this, simply set the notmuch-command variable in emacs to the
3341 name of a script containing:
3343 ssh user@host notmuch "$@"
3345 If the ssh client has enabled connection sharing (ControlMaster
3346 option in OpenSSH), the emacs interface can be quite responsive this
3352 Fix "notmuch search" to print nothing when nothing matches
3354 The 0.4 release had a bug in which:
3356 notmuch search <expression-with-no-matches>
3358 would produce a single blank line of output, (where previous
3359 versions would produce no output. This fix also causes a change in
3360 the --format=json output, (which would previously produce "[]" and
3361 now produces nothing).
3363 Emacs interface improvements
3364 ----------------------------
3366 Fix to allow pipe ('|') command to work when using notmuch over ssh
3368 Fix count of lines in hidden signatures
3370 Omit repeated subject lines in (collapsed) thread display
3372 Display current thread subject in a header line
3374 Provide a "c i" binding to copy a thread ID from the search view
3376 Allow for notmuch-fcc-dirs to have a value of nil
3378 Also, the more complex form of notmuch-fcc-dirs now has a slightly
3379 different format. It no longer has a special first-element, fallback
3380 string. Instead it's now a list of cons cells where the car of each
3381 cell is a regular expression to be matched against the sender
3382 address, and the cdr is the name of a folder to use for an FCC. So
3383 the old fallback behavior can be achieved by including a final cell
3384 of (".*" . "default-fcc-folder").
3386 Vim interface improvements
3387 --------------------------
3389 Felipe Contreras provided a number of updates for the vim interface
3391 These include optimizations, support for newer versions of vim, fixed
3392 support for sending mail on modern systems, new commands, and
3398 Added initial ruby bindings in bindings/ruby
3400 Notmuch 0.4 (2010-11-01)
3401 ========================
3403 New command-line features
3404 -------------------------
3406 `notmuch search --output=(summary|threads|messages|tags|files)`
3408 This new option allows for particular items to be returned from
3409 notmuch searches. The "summary" option is the default and behaves
3410 just as "notmuch search" has historically behaved.
3412 The new option values allow for thread IDs, message IDs, lists of
3413 tags, and lists of filenames to be returned from searches. It is
3414 expected that this new option will be very useful in shell
3415 scripts. For example:
3417 for file in $(notmuch search --output=files <search-terms>); do
3418 <operations-on> "$file"
3421 `notmuch show --format=mbox <search-specification>`
3423 This new option allows for the messages matching a search
3424 specification to be presented as an mbox. Specifically the "mboxrd"
3425 format is used which allows for reversible quoting of lines
3426 beginning with "From ". A reader should remove a single '>' from the
3427 beginning of all lines beginning with one or more '>' characters
3428 followed by the 5 characters "From ".
3430 `notmuch config [get|set] <section>.<item> [value ...]`
3432 The new top-level "config" command allows for any value in the
3433 notmuch configuration file to be queried or set to a new value. Both
3434 single-valued and multi-valued items are supported, as our any
3435 custom items stored in the configuration file.
3437 Avoid setting Bcc header in "notmuch reply"
3439 We decided that this was a bit heavy-handed as the actual mail
3440 user-agent should be responsible for setting any Bcc option. Also,
3441 see below for the notmuch/emacs user-agent now setting an Fcc by
3442 default rather than Bcc.
3444 New library features
3445 --------------------
3447 Add `notmuch_query_get_query_string` and `notmuch_query_get_sort`
3449 These are simply functions for querying properties of a
3450 `notmuch_query_t` object.
3455 Enable Fcc of all sent messages by default (to "sent" directory)
3457 All messages sent from the emacs interface will now be saved to the
3458 notmuch mail store where they will be incorporated to the database
3459 by the next "notmuch new". By default, messages are saved to the
3460 "sent" directory at the top-level of the mail store. This directory
3461 can be customized by means of the "Notmuch Fcc Dirs" option in the
3462 notmuch customize interface.
3464 Ability to all open messages in a thread to a pipe
3466 Historically, the '|' keybinding allows for piping a single message
3467 to an external command. Now, by prefixing this key with a prefix
3468 argument, (for example, by pressing "Control-U |"), all open
3469 messages in the current thread will be sent to the external command.
3471 Optional support for detecting inline patches
3473 This hook is disabled by default but can be enabled with a checkbox
3474 under "Notmuch Show Insert Text/Plain Hook" in the notmuch customize
3475 interface. It allows for inline patches to be detected and treated
3476 as if they were attachments, (with context-sensitive highlighting).
3478 Automatically tag messages as "replied" when sending a reply
3480 Messages replied to within the emacs interface will now be tagged as
3481 "replied". This feature can easily be customized to add or remove
3482 other tags as well. For example, a user might use a tag of
3483 "needs-reply" and can configure this feature to automatically remove
3484 that tag when replying. See "Notmuch Message Mark Replied" in the
3485 notmuch customize interface.
3487 Allow search-result color specifications to overlay each other
3489 For example, one tag can specify the background color of matching
3490 lines, while another can specify the foreground. With this change,
3491 both settings will now be visible simultaneously, (which was not the
3492 case in previous releases). See "Notmuch Search Line Faces" in the
3493 notmuch customize interface.
3495 Make hidden author names still available for incremental search
3497 When there is insufficient space to display all authors of a thread
3498 in search results, the names of hidden authors are now still made
3499 available to emacs' incremental search commands. As the user
3500 searches, matching lines will temporarily expand to show the hidden
3503 New binding of Control-TAB (works like TAB in reverse)
3505 Many notmuch nodes already use TAB to navigate forward through
3506 various items allowing actions, (message headers, email attachments,
3507 etc.). The new Control-TAB binding operates similarly but in the
3510 New build-system features
3511 -------------------------
3513 Various portability fixes have been applied
3515 These include fixes for build failures on at least Solaris, FreeBSD,
3516 and Fedora systems. We're hopeful that the notmuch code base is now
3517 more portable than ever before.
3519 Arrange for libnotmuch to be found automatically after make install
3521 The notmuch build system is now careful to help the user avoid
3522 errors of the form "libnotmuch.so could not be found" immediately
3523 after installing. This support takes two forms:
3525 1. If the library is installed to a system directory,
3526 (configured in /etc/ld.so.conf), then "make install" will
3527 automatically run ldconfig.
3529 2. If the library is installed to a non-system directory, the
3530 build system adds a `DR_RUNPATH` entry to the final binary
3531 pointing to the directory to which the library is installed.
3533 When this support works, the user should be able to run notmuch
3534 immediately after "make install", without any errors trying to find
3535 the notmuch library, and without having to manually set environment
3536 variables such as `LD_LIBRARY_PATH`.
3538 Check compiler/linker options before using them
3540 The configure script now carefully checks that any desired
3541 compilation options, (whether for enabling compiler warnings, or for
3542 embedding rpath, etc.), are supported. Only supported options are
3543 used in the resulting Makefile.
3545 New test-suite features
3546 -----------------------
3548 New modularization of test suite
3550 Thanks to a gracious relicensing of the test-suite infrastructure
3551 from the git project, notmuch now has a modular test suite. This
3552 provides the ability to run individual sections of the test suite
3553 rather than the whole things. It also provides better summary of
3554 test results, with support for tests that are expected to fail
3555 (BROKEN and FIXED) in addition to PASS and FAIL. Finally, it makes
3556 it easy to run the test suite within valgrind (pass --valgrind to
3557 notmuch-test or to any sub-script) which has been very useful.
3559 New testing of emacs interface
3561 The test suite has been augmented to allow automated testing of the
3562 emacs interfaces. So far, this includes basic searches, display of
3563 threads, and tag manipulation. This also includes a test that a new
3564 message can successfully be sent out through a (dummy) SMTP server
3565 and that said message is successfully integrated into the notmuch
3566 database via the FCC setting.
3571 Fix potential corruption of database when "notmuch new" is interrupted
3573 Previously, an interruption of "notmuch new" would (rarely) result
3574 in a corrupt database. The corruption would manifest itself by a
3575 persistent error of the form:
3577 document ID of 1234 has no thread ID
3579 The message-adding code has been carefully audited and reworked to
3580 avoid this sort of corruption regardless of when it is interrupted.
3582 Fix failure with extremely long message ID headers
3584 Previously, a message with an extremely long message ID, (say, more
3585 than 300 characters), would fail to be added to notmuch, (triggering
3586 Xapian exceptions). This has now been fixed.
3588 Fix for messages with "charset=unknown-8bit"
3590 Previously, messages with this charset would cause notmuch to emit a
3591 GMime warning, (which would then trip up emacs or other interfaces
3592 parsing the notmuch results).
3594 Fix `notmuch_query_search_threads` function to return NULL on any exception
3596 Fix "notmuch search" to return non-zero if `notmuch_query_search_threads`
3599 Previously, this command could confusingly report a Xapian
3600 exception, yet still return an error code of 0. It now correctly
3601 returns a failing error code of 1 in this case.
3606 Fix to handle a message with a subject containing, for example "[1234]"
3608 Previously, a message subject containing a sequence of digits within
3609 square brackets would cause the emacs interface to mis-parse the
3610 output of "notmuch search". This would result in the message being
3611 mis-displayed and prevent the user from manipulating the message in
3612 the emacs interface.
3614 Fix to correctly handle message IDs containing ".."
3616 The emacs interface now properly quotes message IDs to avoid a
3617 Xapian bug in which the ".." within a message ID would be
3618 misinterpreted as a numeric range specification.
3620 Python-binding fixes
3621 --------------------
3623 The python bindings for notmuch have been updated to work with python3.
3625 Debian-specific fixes
3626 ---------------------
3628 Fix emacs initialization so "M-x notmuch" works for users by default
3630 Now, a new Debian user can immediately run "emacs -f notmuch" after
3631 "apt-get install notmuch". Previously, the user would have had to
3632 edit the ~/.emacs file to add "(require 'notmuch)" before this would
3635 Notmuch 0.3.1 (2010-04-27)
3636 ==========================
3641 Fix an infinite loop in "notmuch reply"
3643 This bug could be triggered by replying to a message where the
3644 user's primary email address did not appear in the To: header and
3645 the user had not configured any secondary email addresses. The bug
3646 was a simple re-use of the same iterator variable in nested loops.
3648 Fix a potential SEGV in "notmuch search"
3650 This bug could be triggered by an author name ending in a ','.
3651 Admittedly - that's almost certainly a spam email, but we never
3652 want notmuch to crash.
3657 Fix calculations for line wrapping in the primary "notmuch" view
3659 Fix Fcc support to prompt to create a directory if the specified Fcc
3660 directory does not exist
3665 Fix build on OpenSolaris (at least) due to missing 'extern "C"' block
3667 Without this, the C++ sources could not find strcasestr and the
3668 final linking of notmuch would fail.
3670 Notmuch 0.3 (2010-04-27)
3671 ========================
3673 New command-line features
3674 -------------------------
3676 User-configurable tags for new messages
3678 A new "new.tags" option is available in the configuration file to
3679 determine which tags are applied to new messages. Run "notmuch
3680 setup" to generate new documentation within ~/.notmuch-config on how
3681 to specify this value.
3683 Threads search results named based on subjects that match search
3685 This means that when new mails arrived to a thread you've previously
3686 read, and the new mails have a new subject, you will see that
3687 subject in the search results rather than the old subject.
3689 Faster operation of "notmuch tag" (avoid unneeded sorting)
3691 Since the user just wants to tag all matching messages, we can make
3692 things perform a bit faster by avoiding the sort.
3694 Even Better guessing of From: header for "notmuch reply"
3696 Notmuch now looks at a number of headers when trying to figure out
3697 the best From: header to use in a reply. This is helpful if you have
3698 several configured email addresses, and you also subscribe to various
3699 mailing lists with different addresses, (so that mails you are
3700 replying to won't always include your subscribed address in the To:
3703 Indication of author names that match a search
3705 When notmuch displays threads as the result of a search, it now
3706 lists the authors that match the search before listing the other
3707 authors in the thread. It inserts a pipe '|' symbol between the last
3708 matching and first non-matching author. This is especially useful in
3709 a search that includes tag:unread. Now the authors of the unread
3710 messages in the thread are listed first.
3712 New: Python bindings
3713 --------------------
3715 Sebastian Spaeth has contributed his python bindings for the notmuch
3716 library to the central repository. These bindings were previously
3717 known as "cnotmuch" within python but have now been renamed to be
3718 accessible with a simple, and more official-looking "import notmuch".
3720 The bindings have already proven very useful as people proficient in
3721 python have been able to easily develop programs to do notmuch-based
3722 searches for email-address completion, maildir-flag synchronization,
3725 These bindings are available within the bindings/python directory, but
3726 are not yet integrated into the top-level Makefiles, nor the top-level
3727 package-building scripts. Improvements are welcome.
3729 Emacs interface improvements
3730 ----------------------------
3732 An entirely new initial view for notmuch, (friendly yet powerful)
3734 Some of us call the new view "notmuch hello" but you can get at it
3735 by simply calling "emacs -f notmuch". The new view provides a search
3736 bar where new searches can be performed. It also displays a list of
3737 recent searches, along with a button to save any of these, giving it
3738 a new name as a "saved search". Many people find these "saved
3739 searches" one of the most convenient ways of organizing their mail,
3740 (providing all of the features of "folders" in other mail clients,
3741 but without any of the disadvantages).
3743 Finally, this view can also optionally display all of the tags that
3744 exist in the database, along with a count for each tag, and a custom
3745 search of messages with that tag that's simply a click (or keypress)
3748 NOTE: For users that liked the original mode of "emacs -f notmuch"
3749 immediately displaying a particular search result, we recommend
3750 instead running something like:
3752 emacs --eval '(notmuch search "tag:inbox" t)'
3754 The "t" means to sort the messages in an "oldest first" order,
3755 (as notmuch would do previously by default). You can also
3756 leave that off to have your search results in "newest first"
3759 Full-featured "customize" support for configuring notmuch
3761 Notmuch now plugs in well to the emacs "customize" mode to make it
3762 much simpler to find things about the notmuch interface that can be
3763 tweaked by the user.
3765 You can get to this mode by starting at the main "Customize" menu in
3766 emacs, then browsing through "Applications", "Mail", and
3767 "Notmuch". Or you can go straight to "M-x customize-group"
3770 Once you're at the customize screen, you'll see a list of documented
3771 options that can be manipulated along with checkboxes, drop-down
3772 selectors, and text-entry boxes for configuring the various
3775 Support for doing tab-completion of email addresses
3777 This support currently relies on an external program,
3778 (notmuch-addresses), that is not yet shipped with notmuch
3779 itself. But multiple, suitable implementations of this program have
3780 already been written that generate address completions by doing
3781 notmuch searches of your email collection. For example, providing
3782 first those addresses that you have composed messages to in the
3785 One such program (implemented in python with the python bindings to
3786 notmuch) is available via:
3788 git clone http://jkr.acm.jhu.edu/git/notmuch_addresses.git
3790 Install that program as notmuch-addresses on your PATH, and then
3791 hitting TAB on a partial email address or name within the To: or Cc:
3792 line of an email message will provide matching completions.
3794 Support for file-based (Fcc) delivery of sent messages to mail store
3796 This isn't yet enabled by default. To enable this, one will have to
3797 set the "Notmuch Fcc Dirs" setting within the notmuch customize
3798 screen, (see its documentation there for details). We anticipate
3799 making this automatic in a future release.
3801 New 'G' key binding to trigger mail refresh (G == "Get new mail")
3803 The 'G' key works wherever '=' works. Before refreshing the screen
3804 it calls an external program that can be used to poll email servers,
3805 run notmuch new and set up specific tags for the new emails. The
3806 script to be called should be configured with the "Notmuch Poll
3807 Script" setting in the customize interface. This script will
3808 typically invoke "notmuch new" and then perhaps several "notmuch
3811 Implement emacs message display with the JSON output from notmuch
3813 This is much more robust than the previous implementation, (where
3814 some HTML mails and mail quoting the notmuch code with the delimiter
3815 characters in it would cause the parser to fall over).
3817 Better handling of HTML messages and MIME attachments (inline images!)
3819 Allow for any MIME parts that emacs can display to be displayed
3820 inline. This includes inline viewing of image attachments, (provided
3821 the window is large enough to fit the image at its natural size).
3823 Much more robust handling of HTML messages. Currently both text/plain
3824 and text/html alternates will be rendered next to each other. In a
3825 future release, users will be able to decide to see only one or the
3826 other representation.
3828 Each attachment now has its own button so that attachments can be
3829 saved individually (the 'w' key is still available to save all
3832 Customizable support for tidying of text/plain message content
3834 Many new functions are available for tidying up message
3835 content. These include options such as wrapping long lines,
3836 compressing duplicate blank lines, etc.
3838 Most of these are disabled by default, but can easily be enabled by
3839 clicking the available check boxes under the "Notmuch Show Insert
3840 Text/Plain Hook" within the notmuch customize screen.
3842 New support for searchable citations (even when hidden)
3844 When portions of overly-long citations are hidden, the contents of
3845 these citations will still be available for emacs' standard
3846 "incremental search" functions. When the search matches any portion
3847 of a hidden citation, the citation will become visible temporarily
3848 to display the search result.
3850 More flexible handling of header visibility
3852 As an answer to complaints from many users, the To, Cc, and Date
3853 headers of messages are no longer hidden by default. For those users
3854 that liked that these were hidden, a new "Notmuch Messages Headers
3855 Visible" option in the customize interface can be set to nil. The
3856 visibility of headers can still be toggled on a per-message basis
3857 with the 'h' keybinding.
3859 For users that don't want to see some subset of those headers, the
3860 new "Notmuch Message Headers" variable can be customized to list
3861 only those headers that should be present in the display of a message.
3863 The Return key now toggles message visibility anywhere
3865 Previously this worked only on the first summary-line of a message.
3867 Customizable formatting of search results
3869 The user can easily customize the order, width, and formatting of
3870 the various fields in a "notmuch search" buffer. See the "Notmuch
3871 Search Result Format" section of the customize interface.
3873 Generate nicer names for search buffers when using a saved search
3875 Add a notmuch User-Agent header when sending mail from notmuch/emacs
3877 New keybinding (M-Ret) to open all collapsed messages in a thread
3882 Provide a new `NOTMUCH_SORT_UNSORTED` value for queries
3884 This can be somewhat faster when sorting simply isn't desired. For
3885 example when collecting a set of messages that will all be
3886 manipulated identically, (adding a tag, removing a tag, deleting the
3887 messages), then there's no advantage to sorting the messages by
3893 Fix to compile against GMime 2.6
3895 Previously notmuch insisted on being able to find GMime 2.4, (even
3896 though GMime 2.6 would have worked all along).
3898 Fix configure script to accept (and ignore) various standard options
3900 For example, those that the Gentoo build scripts expect configure to
3901 accept are now all accepted.
3906 A large number of new tests for the many new features
3908 Better display of output from failed tests
3910 Now shows failures with diff rather than forcing the user to gaze at
3911 complete actual and expected output looking for deviation.
3913 Notmuch 0.2 (2010-04-16)
3914 ========================
3916 This is the second release of the notmuch mail system, with actual
3917 detailed release notes this time!
3919 This release consists of a number of minor new features that make
3920 notmuch more pleasant to use, and a few fairly major bug fixes.
3922 We didn't quite hit our release target of "about a week" from the 0.1
3923 release, (0.2 is happening 11 days after 0.1), but we hope to do
3924 better for next week. Look forward to some major features coming to
3925 notmuch in subsequent releases.
3932 Better guessing of From: header
3934 Notmuch now tries harder to guess which configured address should be
3935 used as the From: line in a "notmuch reply". It will examine the
3936 Received: headers if it fails to find any configured address in To:
3937 or Cc:. This allows it to often choose the correct address even when
3938 replying to a message sent to a mailing list, and not directly to a
3941 Make "notmuch count" with no arguments count all messages
3943 Previously, it was hard to construct a search term that was
3944 guaranteed to match all messages.
3946 Provide a new special-case search term of "*" to match all messages
3948 This can be used in any command accepting a search term, such as
3949 "notmuch search '*'". Note that you'll want to take care that the
3950 shell doesn't expand * against the current files. And note that the
3951 support for "*" is a special case. It's only meaningful as a single
3952 search term and loses its special meaning when combined with any
3955 Automatically detect thread connections even when a parent message is
3958 Previously, if two or more message were received with a common
3959 parent, but that parent was not received, then these messages would
3960 not be recognized as belonging to the same thread. This is now fixed
3961 so that such messages are properly connected in a thread.
3966 Fix potential data loss in "notmuch new" with SIGINT
3968 One code path in "notmuch new" was not properly handling
3969 SIGINT. Previously, this could lead to messages being removed from
3970 the database (and their tags being lost) if the user pressed
3971 Control-C while "notmuch new" was working.
3973 Fix segfault when a message includes a MIME part that is empty
3975 Fix handling of non-ASCII characters with --format=json
3977 Previously, characters outside the range of 7-bit ASCII were
3978 silently dropped from the JSON output. This led to corrupted display
3979 of utf-8 content in the upcoming notmuch web-based frontends.
3981 Fix headers to be properly decoded in "notmuch reply"
3983 Previously, the user might see:
3985 Subject: Re: =?iso-8859-2?q?Rozlu=E8ka?=
3989 Subject: Re: Rozlučka
3991 The former text is properly encoded to be RFC-compliant SMTP, will
3992 be sent correctly, and will be properly decoded by the
3993 recipient. But the user trying to edit the reply would likely be
3994 unable to read or edit that field in its encoded form.
3996 Emacs client features
3997 ---------------------
3999 Show the last few lines of citations as well as the first few lines
4001 It's often the case that the last sentence of a citation is what is
4002 being replied to directly, so the last few lines are often much more
4003 important. The number of lines shown at the beginning and end of any
4004 citation can be configured, (notmuch-show-citation-lines-prefix and
4005 notmuch-show-citation-lines-suffix).
4007 The '+' and '-' commands in the search view can now add and remove
4010 Selective bulk tagging is now possible by selecting a region of
4011 threads and then using either the '+' or '-' keybindings. Bulk
4012 tagging is still available for all threads matching the current
4013 search with the '*' binding.
4015 More meaningful buffer names for thread-view buffers
4017 Notmuch now uses the Subject of the thread as the buffer
4018 name. Previously it was using the thread ID, which is a meaningless
4021 Provide for customized colors of threads in search view based on tags
4023 See the documentation of notmuch-search-line-faces, (or us "M-x
4024 customize" and browse to the "notmuch" group within "Applications"
4025 and "Mail"), for details on how to configure this colorization.
4027 Build-system features
4028 ---------------------
4030 Add support to properly build libnotmuch on Darwin systems (OS X)
4032 Add support to configure for many standard options
4034 We include actual support for:
4036 --includedir --mandir --sysconfdir
4038 And accept and silently ignore several more:
4040 --build --infodir --libexecdir --localstatedir
4041 --disable-maintainer-mode --disable-dependency-tracking
4043 Install emacs client in "make install" rather than requiring a
4044 separate "make install-emacs"
4046 Automatically compute versions numbers between releases
4048 This support uses the git-describe notation, so a version such as
4049 0.1-144-g43cbbfc indicates a version that is 144 commits since the
4050 0.1 release and is available as git commit "43cbbfc".
4052 Add a new "make test" target to run the test suite and actually
4055 Notmuch 0.1 (2010-04-05)
4056 ========================
4058 This is the first release of the notmuch mail system.
4060 It includes the libnotmuch library, the notmuch command-line
4061 interface, and an emacs-based interface to notmuch.
4063 Note: Notmuch will work best with Xapian 1.0.18 (or later) or Xapian
4064 1.1.4 (or later). Previous versions of Xapian (whether 1.0 or 1.1) had
4065 a performance bug that made notmuch very slow when modifying
4066 tags. This would cause distracting pauses when reading mail while
4067 notmuch would wait for Xapian when removing the "inbox" and "unread"
4068 tags from messages in a thread.
4075 indent-tabs-mode: nil
