1 Notmuch 0.12 (2012-xx-xx)
2 =========================
9 "notmuch reply" has gained the ability to create a reply template
10 for replying just to the sender of the message, in addition to reply
11 to all. The feature is available through the new command line option
12 --reply-to=(all|sender).
16 Tags can be automatically excluded from search results by adding them
17 to the new 'search.exclude_tags' option in the Notmuch config file.
19 This behaviour can be overridden by explicitly including an excluded
20 tag in your query, for example:
22 notmuch search $your_query and tag:$excluded_tag
24 Existing users will probably want to run "notmuch setup" again to add
25 the new well-commented [search] section to the configuration file.
27 For new configurations, accepting the default setting will cause the
28 tags "deleted" and "spam" to be excluded, equivalent to running:
30 notmuch config set search.exclude_tags deleted spam
32 Mail store folder/file ignore
34 A new configuration option, `new.ignore`, lets users specify a
35 ;-separated list of file and directory names that will not be
36 searched for messages by "notmuch new".
43 The Emacs interface has, with the new CLI support, gained the
44 ability to reply to sender in addition to reply to all. In both show
45 and search modes, 'r' has been bound to reply to sender, replacing
46 reply to all, which now has key binding 'R'.
48 More flexible and consistent tagging operations
50 All tagging operations ("+", "-", "*") now accept multiple tags with
51 "+" or "-" prefix, like "*" operation in notmuch-search view before.
53 "*" operation (`notmuch-show-tag-all') is now available in
56 `Notmuch-show-{add,remove}-tag' functions no longer accept tag
57 argument, `notmuch-show-tag-message' should be used instead. Custom
58 bindings using these functions should be updated, e.g.:
60 (notmuch-show-remove-tag "unread")
64 (notmuch-show-tag-message "-unread")
71 notmuch_query_add_tag_exclude supports the new tag exclusion
74 Python bindings changes
75 -----------------------
77 Python 3.2 compatibility
79 The python bindings are now compatible with both python 2.5+ and 3.2.
81 Added missing unicode conversions
83 Python strings have to be encoded to and decoded from utf-8 when
84 calling libnotmuch functions. Porting the bindings to python 3.2
85 revealed a few function calls that were missing these conversions.
90 Compatibility with GMime 2.6
92 It is now possible to build notmuch against both GMime 2.4 and 2.6.
93 However, a bug in current GMime 2.6 causes notmuch not to report
94 signatures where the signer key is unavailable (GNOME bug 668085).
96 Notmuch 0.11.1 (2012-02-03)
97 ===========================
102 Fix error handling in python bindings.
104 The python bindings in 0.11 failed to detect NULL pointers being
105 returned from libnotmuch functions and thus failed to raise
106 exceptions to indicate the error condition. Any subsequent calls
107 into libnotmuch caused segmentation faults.
109 Quote MML tags in replies
111 MML tags are text codes that Emacs uses to indicate attachments
112 (among other things) in messages being composed. The Emacs
113 interface did not quote MML tags in the quoted text of a reply.
114 User could be tricked into replying to a maliciously formatted
115 message and not editing out the MML tags from the quoted text. This
116 could lead to files from the user's machine being attached to the
117 outgoing message. The Emacs interface now quotes these tags in
118 reply text, so that they do not effect outgoing messages.
120 Notmuch 0.11 (2012-01-13)
121 =========================
123 Command-Line Interface
124 ----------------------
128 Hooks have been introduced to notmuch. Hooks are scripts that notmuch
129 invokes before and after certain actions. Initially, "notmuch new"
130 supports "pre-new" and "post-new" hooks that are run before and after
131 importing new messages into the database.
133 notmuch reply --decrypt bugfix
135 The "notmuch reply" command with --decrypt argument had a rarely
136 occurring bug that caused an encrypted message not to be decrypted
137 sometimes. This is now fixed.
142 Automatic tag query optimization
144 "notmuch tag" now automatically optimizes the user's query to
145 exclude messages whose tags won't change. In the past, we've
146 suggested that people do this by hand; this is no longer necessary.
148 Don't sort messages when creating a dump file
150 This speeds up tag dumps considerably, without any loss of
151 information. To replicate the old behavior of sorted output (for
152 example to compare two dump files), one can use e.g. sort(1).
157 Reduction of memory leaks
159 Two memory leaks when searching and showing messages were identified
160 and fixed in this release.
167 notmuch-show-advance (bound to the spacebar in notmuch-show-mode) had
168 a bug that caused it to always jump to the next message, even if it
169 should have scrolled down to show more of the current message instead.
172 Support "notmuch new" as a notmuch-poll-script
174 It's now possible to use "notmuch new" as a notmuch-poll-script
175 directly. This is also the new default. This allows taking better
176 advantage of the "notmuch new" hooks from emacs without intermediate
179 Improvements in saved search management
181 New saved searches are now appended to the list of saved searches,
182 not inserted in front. It's also possible to define a sort function
183 for displaying saved searches; alphabetical sort is provided.
185 Hooks for notmuch-hello
187 Two new hooks have been added: "notmuch-hello-mode-hook" (called after
188 entering notmuch-hello-mode) and "notmuch-hello-refresh-hook" (called
189 after updating a notmuch-hello buffer).
191 New face for crypto parts headers
193 Crypto parts used to be displayed with a hardcoded color. A new face
194 has been introduced to fix this: notmuch-crypto-part-header. It
195 defaults to the same value as before, but can be customized to match
198 Use space as default thousands separator
200 Large numbers in notmuch-hello are now displayed using a space as
201 thousands separator (e.g. "123 456" instead of "123,456"). This can be
202 changed by customizing "notmuch-hello-thousands-separator".
204 Call notmuch-show instead of notmuch-search when clicking on
205 buttonized id: links.
207 New function notmuch-show-advance
209 This new function advances through just the current thread, and is
210 less invasive than notmuch-show-advance-and-archive. It can easily
211 be bound to SPC with:
213 (define-key notmuch-show-mode-map " " 'notmuch-show-advance)
215 Various performance improvements.
220 The tool contrib/notmuch-deliver helps with initial delivery and
221 tagging of mail (replacing running notmuch new).
224 Notmuch 0.10.2 (2011-12-04)
225 ===========================
230 Fix crash in python bindings.
232 The python bindings did not call g_type_init, which caused crashes
233 for some, but not all users.
235 Notmuch 0.10.1 (2011-11-25)
236 ===========================
243 Argument processing changes in 0.10 introduced a bug where "notmuch
244 --help" crashed while "notmuch help" worked fine. This is fixed in
247 Notmuch 0.10 (2011-11-23)
248 =========================
250 New build and testing features
251 ------------------------------
253 Emacs tests are now done in dtach. This means that dtach is now
254 needed to run the notmuch test suite, at least until the checking for
255 prerequisites is improved.
257 Full test coverage of the stashing feature in Emacs.
259 New command-line features
260 -------------------------
262 Add "notmuch restore --accumulate" option
264 The --accumulate switch causes the union of the existing and new tags to be
265 applied, instead of replacing each message's tags as they are read in from
268 Add search terms to "notmuch dump"
270 The dump command now takes an optional search term much like notmuch
271 search/show/tag. The output file argument of dump is deprecated in
272 favour of using stdout.
274 Add "notmuch search" --offset and --limit options
276 The search command now takes options --offset=[-]N and --limit=N to limit
277 the number of results shown.
279 Add "notmuch count --output" option
281 The count command is now capable of counting threads in addition to
282 messages. This is selected using the new --output=(threads|messages) option.
284 New emacs UI features
285 ---------------------
287 Add tab-completion for notmuch-search and notmuch-search-filter
289 These functions now support completion tags for query parts
290 starting with "tag:".
292 Turn "id:MSG-ID" links into buttons associated with notmuch searches
294 Text of the form "id:MSG-ID" in mails is now a clickable button that
295 opens a notmuch search for the given message id.
297 Add keybinding ('c I') for stashing Message-ID's without an id: prefix
299 Reduces manual labour when stashing them for use outside notmuch.
301 Do not query on notmuch-search exit
303 It is harmless to kill the external notmuch process, so the user
304 is no longer interrogated when they interrupt a search.
309 Emacs now constructs large search buffers more efficiently
311 Search avoids opening and parsing message files
313 We now store more information in the database so search no longer
314 has to open every message file to get basic headers. This can
315 improve search speed by as much as 10X, but taking advantage of this
316 requires a database rebuild:
318 notmuch dump > notmuch.dump
319 # Backup, then remove notmuch database ($MAIL/.notmuch)
321 notmuch restore notmuch.dump
323 New collection of add-on tools
324 ------------------------------
326 The source directory "contrib" contains tools built on notmuch. These
327 tools are not part of notmuch, and you should check their individual
328 licenses. Feel free to report problems with them to the notmuch
331 nmbug - share tags with a given prefix
333 nmbug helps maintain a git repo containing all tags with a given
334 prefix (by default "notmuch::"). Tags can be shared by commiting
335 them to git in one location and restoring in another.
337 Notmuch 0.9 (2011-10-01)
338 ========================
340 New, general features
341 ---------------------
343 Correct handling of interruptions during "notmuch new"
345 "notmuch new" now operates as a series of small, self-consistent
346 transactions, so it can correctly resume after an interruption or
347 crash. Previously, interruption could lose existing tags, fail to
348 detect messages on resume, or leave the database in a state
349 temporarily or permanently inconsistent with the mail store.
356 notmuch_database_begin_atomic and notmuch_database_end_atomic allow
357 multiple database operations to be performed atomically.
359 notmuch_database_find_message_by_filename does exactly what it says.
363 notmuch_database_find_message (and n_d_f_m_by_filename) now return
364 a status indicator and uses an output parameter for the
365 message. This change required changing the SONAME of libnotmuch to
368 Python bindings changes
369 -----------------------
371 - Re-encode python unicode objects to utf-8 before passing back to
373 - Support Database().begin_atomic()/end_atomic()
374 - Support Database().find_message_by_filename()
375 NB! This needs a db opened in READ-WRITE mode currently, or it will crash
376 the python process. The is a limitation (=bug) of the underlying libnotmuch.
377 - Fixes where we would not throw NotmuchErrors when we should (Justus Winter)
378 - Update for n_d_find_message* API changes (see above).
380 Ruby bindings changes
381 ---------------------
383 - Wrap new library functions notmuch_database_{begin,end}_atomic.
384 - Add new exception Notmuch::UnbalancedAtomicError.
385 - Rename destroy to destroy! according to Ruby naming conventions.
386 - Update for n_d_find_message* API changes (see above).
391 * Add gpg callback to crypto sigstatus buttons to retrieve/refresh
393 * Add notmuch-show-refresh-view function (and corresponding binding)
394 to refresh the view of a notmuch-show buffer.
396 Reply formatting cleanup
397 ------------------------
399 "notmuch reply" no longer includes notification that non-leafnode
400 MIME parts are being suppressed.
402 Notmuch 0.8 (2011-09-10)
403 ========================
405 Improved handling of message/rfc822 parts
407 Both in the CLI and the emacs interface. Output of rfc822 parts now
408 includes the primary headers, as well as the body and all subparts.
409 Output of the completely raw rfc822-formatted message, including all
410 headers, is unfortunately not yet supported (but hopefully will be
413 Improved Build system portability
415 Certain parts of the shell script generating notmuch.sym were
416 specific to the GNU versions of sed and nm. The new version should
417 be more portable to e.g. OpenBSD.
419 Documentation update for Ruby bindings
421 Added documentation, typo fixes, and improved support for rdoc.
423 Unicode, iterator, PEP8 changes for python bindings
425 - PEP8 (code formatting) changes for python files.
426 - Remove Tags.__len__ ; see 0.6 release notes for motivation.
427 - Decode headers as UTF8, encode (unicode) database paths as UTF8.
429 Notmuch 0.7 (2011-08-01)
430 ========================
432 Vim interface improvements
433 --------------------------
435 Jason Woofenden provided a number of bug fixes for the Vim interface
437 * fix citation/signature fold lengths
438 * fix cig/cit parsing within multipart/*
439 * fix on-screen instructions for show-signature
440 * fix from list reformatting in search view
441 * fix space key: now archives (did opposite)
443 Uwe Kleine-König contributed
445 * use full path for sendmail/doc fix
446 * fix compose temp file name
448 Python Bindings changes
449 -----------------------
451 Sebastian Spaeth contributed two changes related to unicode and UTF8:
453 * message tags are now explicitly unicode
454 * query string is encoded as a UTF8 byte string
456 Build-System improvements
457 ------------------------
459 Generate notmuch.sym after the relevant object files
461 This fixes a bug in parallel building. Thanks to Thomas Jost for the
464 Notmuch 0.6.1 (2011-07-17)
465 ==========================
470 Re-export Xapian exception typeinfo symbols.
472 It turned out our aggressive symbol hiding caused problems for
473 people running gcc 4.4.5.
475 Notmuch 0.6 (2011-07-01)
476 =======================
477 New, general features
478 ---------------------
479 Folder-based searching
481 Notmuch queries can now include a search term to match the
482 directories in which mail files are stored (within the mail
483 storage). The syntax is as follows:
487 For example, one might use things such as:
493 to match any path containing a directory "spam", "work/todo", or
494 containing a directory starting with "2011-", respectively.
496 This feature is particularly useful for users of delivery-agent
497 software (such as procmail or maildrop) that is filtering mail and
498 delivering it to particular folders, or users of systems such as
499 Gmail that use filesystem directories to indicate message tags.
501 NOTE: Only messages that are newly indexed with this version of
502 notmuch will be searchable with folder: terms. In order to enable
503 this feature for all mail, the entire notmuch index will need to be
506 notmuch dump > notmuch.dump
507 # Backup, then remove notmuch database ($MAIL/.notmuch)
509 notmuch restore notmuch.dump
513 Both the command line interface and the emacs-interface have new
514 support for PGP/MIME, detailed below. Thanks to Daniel Kahn Gillmor
515 and Jameson Graef Rollins for making this happen.
517 New, automatic tags: "signed" and "encrypted"
519 These tags will automatically be applied to messages containing
520 multipart/signed and multipart/encrypted parts.
522 NOTE: Only messages that are newly indexed with this version of
523 notmuch will receive these tags.
525 New command-line features
526 -------------------------
527 Add new "notmuch show --verify" option for signature verification
529 This option instruct notmuch to verify the signature of
530 PGP/MIME-signed parts.
532 Add new "notmuch show --decrypt" and "notmuch reply --decrypt" options
534 This option instructs notmuch to decrypt PGP/MIME-encrypted parts.
535 Note that this feature currently requires gpg-agent and a passphrase entry
536 tool (e.g. pinentry-gtk or pinentry-curses).
538 Proper nesting of multipart parts in "notmuch show" output
540 MIME parts are now display with proper nesting to reflect original
541 MIME hierarchy of a message. This allows clients to correctly
542 analyze the MIME structure, (such as, for example, determining to
543 which parts a signature part applies).
545 Add new "notmuch show --part" option
547 This is a replacement for the older "notmuch part" command, (which
548 is now deprecated—it should still work as always, but is no longer
549 documented). Putting part output under "notmuch show" allows for all
550 of the "notmuch show" options to be applied when extracting a single
551 part, (such as --format=json for extracting a message part with JSON
554 Deprecate "notmuch search-tags", (in favor of "notmuch search --output=tags *")
556 The "notmuch search-tags" sub-command has been redundant since the
557 addition of the --output=tags option to "notmuch search". We now
558 make that more clear by deprecating "notmuch search-tags", (dropping
559 it from the documentation). We do continue to support the old syntax
560 by translating it internally to the new call.
562 Performance improvements
563 ------------------------
564 Faster searches (by doing fewer searches to construct threads)
566 Whenever a user asks for search results as threads, notmuch first
567 performs a search for messages matching the query, then performs
568 additional searches to find other messages in the resulting threads.
570 Removing inefficiencies and redundancies in these secondary searches
571 results in a measured speedups of 1.5x for a typical search.
573 Faster searches (by doing fewer passes to gather message data)
575 Optimizing Xapian data access patterns (using a single pass to get
576 all message-document data rather than a pass for each data type)
577 results in a measured speedup of 1.7x for a typical search.
579 The benefits of this optimization combine with the preceding
580 optimization. With both in place, Austin Clements measured a speedup
581 of 2.5x for a search of all messages in his inbox (was 4.5s, now
582 1.8s). Thanks, Austin!
584 Faster initial indexing
586 More efficient indexing of new messages results in a measured
587 speedup of 1.4x for the initial indexing of 3 GB of mail (1h 14m
588 rather than 1h 46m). Thanks to Austin Clements and Michal Sojka.
590 Make "notmuch new" faster for unchanged directories
592 Optimizing to not do any further examinations of sub-directories
593 when the filesystem indicates that a directory is unchanged from the
594 last "notmuch new" results in measured speedups of 8.5 for the "No
595 new mail" case, (was 0.77s, now 0.09s). Thanks to Karel Zak.
597 New emacs-interface features
598 ----------------------------
600 Support for PGP/MIME (GnuPG)
602 Automatically indicate validity of signatures for multipart/signed
603 messages. Automatically display decrypted content for
604 multipart/encrypted messages. See the emacs variable
605 notmuch-crypto-process-mime for more information. Note that this
606 needs gpg-agent and a pinentry tool just as the command line tools.
607 Also note there is no support SMIME yet.
609 Output of pipe command is now displayed if pipe command fails
611 This is extremely useful in the common use case of piping a patch to
612 "git am". If git fails to cleanly merge the patch the error messages
613 from the failed merge are now clearly displayed to the user, (where
614 previously they were silently hidden from the user).
616 User-selectable From address
618 A user can choose which configured email addresses should be used as
619 the From address whenever composing a new message. To do so, simply
620 press C-u before the command which will open a new message. Emacs
621 will prompt for the from address to use.
623 The user can customize the "Notmuch Identities" setting in the
624 notmuch customize group in order to use addresses other than those in
625 the notmuch configuration file if desired.
627 The user can also choose to always be prompted for the from address
628 when composing a new message (without having to use C-u) by setting
629 the "Notmuch Always Prompt For Sender" option in the notmuch
632 Hiding of repeated subjects in collapsed thread view
634 In notmuch-show mode, if a collapsed message has the same subject as
635 its parent, the subject is not shown.
637 Automatic detection and hiding of original message in top-posted message
639 When a message contains a line looking something like:
641 ----- Original Message -----
643 emacs hides this and all subsequent lines as an "original message",
644 (allowing the user to click or press enter on the "original message"
645 button to display it again). This makes the handling of top-posted
646 citations work much like conventional citations.
648 New hooks for running code when tags are modified
650 Some users want to perform additional actions whenever a particular
651 tag is added/removed from a message. This could be used to, for
652 example, interface with some external spam-recognition training
653 tool. To facilitate this, two new hooks are added which can be
654 modified in the following settings of the notmuch customize group:
656 Notmuch Before Tag Hook
657 Notmuch After Tag Hook
659 New optional support for hiding some multipart/alternative parts
661 Many emails are sent with redundant content within a
662 multipart/alternative group (such as a text/plain part as well as a
663 text/html part). Users can configure the setting:
665 Notmuch Show All Multipart/Alternative Parts
667 to "off" in the notmuch customize group to have the interface
668 automatically hide some part alternatives (such as text/html
669 parts). This new part hiding is not configured by default yet
670 because there's not yet a simple way to re-display such a hidden
671 part if it is not actually redundant with a displayed part.
673 Better rendering of text/x-vcalendar parts
675 These parts are now displayed in a format suitable for use with the
678 Avoid getting confused by Subject and Author fields with newline characters
680 Replacing all characters with ASCII code less than 32 with a question mark.
682 Cleaner display of From line in email messages (remove double quotes,
683 and drop "name" if it's actually just a repeat of the email address).
685 Vim interface improvements
686 --------------------------
687 Felipe Contreras provided a number of updates for the vim interface:
689 * Using sendmail directly rather than mailx,
690 * Implementing archive in show view
691 * Add support to mark as read in show and search views
692 * Add delete commands
695 Bindings improvements
696 ---------------------
697 Ruby bindings are now much more complete
699 Including QUERY.sort, QUERY.to_s, MESSAGE.maildir_flags_to_tags,
700 MESSAGE.tags_to_maildir_flags, and MESSAGE.get_filenames
702 * Python bindings have been updated and extended
703 (docs online at http://packages.python.org/notmuch/)
706 - Message().get_filenames(),
707 - Message().tags_to_maildir_flags(),Message().maildir_flags_to_tags()
708 - list(Threads()) and list(Messages) works now
710 - Message().__cmp__() and __hash__()
711 These allow, for example:
714 As well as set arithmetic on Messages():
716 s1, s2= set(msgs1), set(msgs2)
721 - len(Messages()) as it exhausted the iterator.
722 Use len(list(Messages())) or
723 Query.count_messages() to get the length.
725 Added initial Go bindings in bindings/go
727 New build-system features
728 -------------------------
729 Added support for building in a directory other than the source directory
731 This can be used with the widely-supported idiom of simply running
732 the configure script from some other directory:
739 Fix to save configure options for future, implicit runs of configure
741 When a user updates the source (such as with "git pull") calling
742 "make" may cause an automatic re-run of the configure script. When
743 this happens, the configure script will automatically be called with
744 the same options the user originally passed in the most-recent
745 manual invocation of configure.
747 New test-suite feature
748 ----------------------
749 Binary for bash for running test suite now located via PATH.
751 The notmuch test suite requires a fairly recent version of bash (>=
752 bash 4). As some systems supply an older version of bash at
753 /bin/bash, the test suite is now updated to search $PATH to locate
754 the bash binary. This allows users of systems with old /bin/bash to
755 simply install bash >= 4 somewhere on $PATH before /bin and then use
758 Support for testing output with a trailing newline.
760 Previously, some tests would fail to notice a difference in the
761 presence/absence of a trailing newline in a program output, (which
762 has led to bugs in the past). Now, carefully-written tests (using
763 test_expect_equal_file rather than test_expect_equal) will detect
764 any change in the presence/absence of a trailing newline. Many tests
765 are updated to take advantage of this.
767 Avoiding accessing user's $HOME while running test suite
769 The test suite now carefully creates its own HOME directory. This
770 allows the test suite to be run with no existing HOME directory, (as
771 some build systems apparently do), and avoids test-suite differences
772 due to configuration files in the users HOME directory.
777 Output *all* files for "notmuch search --output=files"
779 For the cases where multiple files have the same Message ID,
780 previous versions of notmuch would output only one such file. This
781 command is now fixed to correctly output all files.
783 Fixed spurious search results from "overlapped" indexing of addresses
785 This fixed a bug where a search for:
787 to:user@elsewhere.com
789 would incorrectly match a message sent:
791 To: user@example,com, someone@elsewhere.com
793 Fix --output=json when search has no results
795 A bug present since notmuch 0.4 had caused searches with no results
796 to produce an invalid json object. This is now fixed to cleanly
797 return a valid json object representing an empty array "[]" as
800 fix the automatic detection of the From address for "notmuch reply"
801 from the Received headers in some cases.
803 Fix core dump on DragonFlyBSD due to -1 return value from
804 sysconf(_SC_GETPW_R_SIZE_MAX).
806 Cleaned up several memory leaks
808 Eliminated a few, rare segmentation faults and a double-free.
810 Fix libnotmuch library to only export notmuch API functions
812 Previous release of the notmuch library also exported some Xapian
813 C++ exception type symbols. These were never part of the library
814 interface and were never intended to be exported.
816 Emacs-interface bug fixes
817 -------------------------
818 Display any unexpected output or errors from "notmuch search" invocations
820 Previously any misformatted output or trailing error messages were
821 silently ignored. This output is now clearly displayed. This fix was
822 very helpful in identifying and fixing the bug described below.
824 Fix bug where some threads would be missing from large search results
826 When a search returned a "large" number of results, the emacs
827 interface was incorrectly dropping one thread every time the output
828 of the "notmuch search" process spanned the emacs read-buffer. This
831 Avoid re-compression of .gz files (and similar) when saving attachment
833 Emacs was being too clever for its own good and trying to
834 re-compress pre-compressed .gz files when saving such attachments
835 (potentially corrupting the attachment). The emacs interface is
836 fixed to avoid this bug.
838 Fix hiding of a message when a previously-hidden citation is visible
840 Previously the citation would remain visible in this case. This is
841 fixed so that hiding a message hides all parts.
843 Notmuch 0.5 (2010-11-11)
844 ========================
845 New, general features
846 ---------------------
847 Maildir-flag synchronization
849 Notmuch now knows how to synchronize flags in maildir filenames with
850 tags in the notmuch database. The following flag/tag mappings are
859 'S' unread (added when 'S' flag is not present)
861 The synchronization occurs in both directions, (for example, adding
862 the 'S' flag to a file will cause the "unread" tag to be added, and
863 adding the "replied" tag to a message will cause the file to be
864 renamed with an 'R' flag).
866 This synchronization is enabled by default for users of the
867 command-line interface, (though only files in directories named
868 "cur" or "new" will be renamed). It can be disabled by setting the
869 new maildir.synchronize_flags option in the configuration file. For
872 notmuch config set maildir.synchronize_flags false
874 Users upgrading may also want to run "notmuch setup" once (just
875 accept the existing configuration) to get a new, nicely-commented
876 [maildir] section added to the configuration file.
878 For users of the notmuch library, the new synchronization
879 functionality is available with the following two new functions:
881 notmuch_message_maildir_flags_to_tags
882 notmuch_message_tags_to_maildir_flags
884 It is anticipated that future improvements to this support will
885 allow for safe synchronization of the 'T' flag with the "deleted"
886 tag, as well as support for custom flag/tag mappings.
890 Support for querying multiple filenames for a single message
892 It is common for the mailstore to contain multiple files with the
893 same message ID. Previously, notmuch would always hide these
894 duplicate files, (returning a single, arbitrary filename with
895 notmuch_message_get_filename).
897 With this release, library users can access all filenames for a
898 message with the new function:
900 notmuch_message_get_filenames
902 Together with notmuch_filenames_valid, notmuch_filenames_get, and
903 notmuch_filenames_move_to_next it is now possible to iterate over
904 all available filenames for a given message.
906 New command-line features
907 -------------------------
908 New "notmuch show --format=raw" for getting at original email contents
910 This new feature allows for a fully-functional email client to be
911 built on top of the notmuch command-line without needing any direct
912 access to the mail store itself.
914 For example, it's now possible to run "emacs -f notmuch" on a local
915 machine with only ssh access to the mail store/notmuch database. To
916 do this, simply set the notmuch-command variable in emacs to the
917 name of a script containing:
919 ssh user@host notmuch "$@"
921 If the ssh client has enabled connection sharing (ControlMaster
922 option in OpenSSH), the emacs interface can be quite responsive this
927 Fix "notmuch search" to print nothing when nothing matches
929 The 0.4 release had a bug in which:
931 notmuch search <expression-with-no-matches>
933 would produce a single blank line of output, (where previous
934 versions would produce no output. This fix also causes a change in
935 the --format=json output, (which would previously produce "[]" and
936 now produces nothing).
938 Emacs interface improvements
939 ----------------------------
940 Fix to allow pipe ('|') command to work when using notmuch over ssh
942 Fix count of lines in hidden signatures.
944 Omit repeated subject lines in (collapsed) thread display.
946 Display current thread subject in a header line.
948 Provide a "c i" binding to copy a thread ID from the search view.
950 Allow for notmuch-fcc-dirs to have a value of nil.
952 Also, the more complex form of notmuch-fcc-dirs now has a slightly
953 different format. It no longer has a special first-element, fallback
954 string. Instead it's now a list of cons cells where the car of each
955 cell is a regular expression to be matched against the sender
956 address, and the cdr is the name of a folder to use for an FCC. So
957 the old fallback behavior can be achieved by including a final cell
958 of (".*" . "default-fcc-folder").
960 Vim interface improvements
961 --------------------------
962 Felipe Contreras provided a number of updates for the vim interface.
964 These include optimizations, support for newer versions of vim, fixed
965 support for sending mail on modern systems, new commands, and
970 Added initial ruby bindings in bindings/ruby
972 Notmuch 0.4 (2010-11-01)
973 ========================
974 New command-line features
975 -------------------------
976 notmuch search --output=(summary|threads|messages|tags|files)
978 This new option allows for particular items to be returned from
979 notmuch searches. The "summary" option is the default and behaves
980 just as "notmuch search" has historically behaved.
982 The new option values allow for thread IDs, message IDs, lists of
983 tags, and lists of filenames to be returned from searches. It is
984 expected that this new option will be very useful in shell
985 scripts. For example:
987 for file in $(notmuch search --output=files <search-terms>); do
988 <operations-on> "$file"
991 notmuch show --format=mbox <search-specification>
993 This new option allows for the messages matching a search
994 specification to be presented as an mbox. Specifically the "mboxrd"
995 format is used which allows for reversible quoting of lines
996 beginning with "From ". A reader should remove a single '>' from the
997 beginning of all lines beginning with one or more '>' characters
998 followed by the 5 characters "From ".
1000 notmuch config [get|set] <section>.<item> [value ...]
1002 The new top-level "config" command allows for any value in the
1003 notmuch configuration file to be queried or set to a new value. Both
1004 single-valued and multi-valued items are supported, as our any
1005 custom items stored in the configuration file.
1007 Avoid setting Bcc header in "notmuch reply"
1009 We decided that this was a bit heavy-handed as the actual mail
1010 user-agent should be responsible for setting any Bcc option. Also,
1011 see below for the notmuch/emacs user-agent now setting an Fcc by
1012 default rather than Bcc.
1014 New library features
1015 --------------------
1016 Add notmuch_query_get_query_string and notmuch_query_get_sort
1018 These are simply functions for querying properties of a
1019 notmuch_query_t object.
1023 Enable Fcc of all sent messages by default (to "sent" directory)
1025 All messages sent from the emacs interface will now be saved to the
1026 notmuch mail store where they will be incorporated to the database
1027 by the next "notmuch new". By default, messages are saved to the
1028 "sent" directory at the top-level of the mail store. This directory
1029 can be customized by means of the "Notmuch Fcc Dirs" option in the
1030 notmuch customize interface.
1032 Ability to all open messages in a thread to a pipe
1034 Historically, the '|' keybinding allows for piping a single message
1035 to an external command. Now, by prefixing this key with a prefix
1036 argument, (for example, by pressing "Control-U |"), all open
1037 messages in the current thread will be sent to the external command.
1039 Optional support for detecting inline patches
1041 This hook is disabled by default but can be enabled with a checkbox
1042 under "Notmuch Show Insert Text/Plain Hook" in the notmuch customize
1043 interface. It allows for inline patches to be detected and treated
1044 as if they were attachments, (with context-sensitive highlighting).
1046 Automatically tag messages as "replied" when sending a reply
1048 Messages replied to within the emacs interface will now be tagged as
1049 "replied". This feature can easily be customized to add or remove
1050 other tags as well. For example, a user might use a tag of
1051 "needs-reply" and can configure this feature to automatically remove
1052 that tag when replying. See "Notmuch Message Mark Replied" in the
1053 notmuch customize interface.
1055 Allow search-result color specifications to overlay each other
1057 For example, one tag can specify the background color of matching
1058 lines, while another can specify the foreground. With this change,
1059 both settings will now be visible simultaneously, (which was not the
1060 case in previous releases). See "Notmuch Search Line Faces" in the
1061 notmuch customize interface.
1063 Make hidden author names still available for incremental search.
1065 When there is insufficient space to display all authors of a thread
1066 in search results, the names of hidden authors are now still made
1067 available to emacs' incremental search commands. As the user
1068 searches, matching lines will temporarily expand to show the hidden
1071 New binding of Control-TAB (works like TAB in reverse)
1073 Many notmuch nodes already use TAB to navigate forward through
1074 various items allowing actions, (message headers, email attachments,
1075 etc.). The new Control-TAB binding operates similarly but in the
1078 New build-system features
1079 -------------------------
1080 Various portability fixes have been applied
1082 These include fixes for build failures on at least Solaris, FreeBSD,
1083 and Fedora systems. We're hopeful that the notmuch code base is now
1084 more portable than ever before.
1086 Arrange for libnotmuch to be found automatically after make install
1088 The notmuch build system is now careful to help the user avoid
1089 errors of the form "libnotmuch.so could not be found" immediately
1090 after installing. This support takes two forms:
1092 1. If the library is installed to a system directory,
1093 (configured in /etc/ld.so.conf), then "make install" will
1094 automatically run ldconfig.
1096 2. If the library is installed to a non-system directory, the
1097 build system adds a DR_RUNPATH entry to the final binary
1098 pointing to the directory to which the library is installed.
1100 When this support works, the user should be able to run notmuch
1101 immediately after "make install", without any errors trying to find
1102 the notmuch library, and without having to manually set environment
1103 variables such as LD_LIBRARY_PATH.
1105 Check compiler/linker options before using them
1107 The configure script now carefully checks that any desired
1108 compilation options, (whether for enabling compiler warnings, or for
1109 embedding rpath, etc.), are supported. Only supported options are
1110 used in the resulting Makefile.
1112 New test-suite features
1113 -----------------------
1114 New modularization of test suite.
1116 Thanks to a gracious relicensing of the test-suite infrastructure
1117 from the git project, notmuch now has a modular test suite. This
1118 provides the ability to run individual sections of the test suite
1119 rather than the whole things. It also provides better summary of
1120 test results, with support for tests that are expected to fail
1121 (BROKEN and FIXED) in addition to PASS and FAIL. Finally, it makes
1122 it easy to run the test suite within valgrind (pass --valgrind to
1123 notmuch-test or to any sub-script) which has been very useful.
1125 New testing of emacs interface.
1127 The test suite has been augmented to allow automated testing of the
1128 emacs interfaces. So far, this includes basic searches, display of
1129 threads, and tag manipulation. This also includes a test that a new
1130 message can successfully be sent out through a (dummy) SMTP server
1131 and that said message is successfully integrated into the notmuch
1132 database via the FCC setting.
1136 Fix potential corruption of database when "notmuch new " is interrupted.
1138 Previously, an interruption of "notmuch new" would (rarely) result
1139 in a corrupt database. The corruption would manifest itself by a
1140 persistent error of the form:
1142 document ID of 1234 has no thread ID
1144 The message-adding code has been carefully audited and reworked to
1145 avoid this sort of corruption regardless of when it is interrupted.
1147 Fix failure with extremely long message ID headers.
1149 Previously, a message with an extremely long message ID, (say, more
1150 than 300 characters), would fail to be added to notmuch, (triggering
1151 Xapian exceptions). This has now been fixed.
1153 Fix for messages with "charset=unknown-8bit"
1155 Previously, messages with this charset would cause notmuch to emit a
1156 GMime warning, (which would then trip up emacs or other interfaces
1157 parsing the notmuch results).
1159 Fix notmuch_query_search_threads function to return NULL on any exception
1161 Fix "notmuch search" to return non-zero if notmuch_query_search_threads fails
1163 Previously, this command could confusingly report a Xapian
1164 exception, yet still return an error code of 0. It now correctly
1165 returns a failing error code of 1 in this case.
1169 Fix to handle a message with a subject containing, for example "[1234]"
1171 Previously, a message subject containing a sequence of digits within
1172 square brackets would cause the emacs interface to mis-parse the
1173 output of "notmuch search". This would result in the message being
1174 mis-displayed and prevent the user from manipulating the message in
1175 the emacs interface.
1177 Fix to correctly handle message IDs containing ".."
1179 The emacs interface now properly quotes message IDs to avoid a
1180 Xapian bug in which the ".." within a message ID would be
1181 misinterpreted as a numeric range specification.
1183 Python-binding fixes
1184 --------------------
1185 The python bindings for notmuch have been updated to work with python3.
1187 Debian-specific fixes
1188 ---------------------
1189 Fix emacs initialization so "M-x notmuch" works for users by default.
1191 Now, a new Debian user can immediately run "emacs -f notmuch" after
1192 "apt-get install notmuch". Previously, the user would have had to
1193 edit the ~/.emacs file to add "(require 'notmuch)" before this would
1196 Notmuch 0.3.1 (2010-04-27)
1197 ==========================
1200 Fix an infinite loop in "notmuch reply"
1202 This bug could be triggered by replying to a message where the
1203 user's primary email address did not appear in the To: header and
1204 the user had not configured any secondary email addresses. The bug
1205 was a simple re-use of the same iterator variable in nested loops.
1207 Fix a potential SEGV in "notmuch search"
1209 This bug could be triggered by an author name ending in a ','.
1210 Admittedly - that's almost certainly a spam email, but we never
1211 want notmuch to crash.
1215 Fix calculations for line wrapping in the primary "notmuch" view.
1217 Fix Fcc support to prompt to create a directory if the specified Fcc
1218 directory does not exist.
1222 Fix build on OpenSolaris (at least) due to missing 'extern "C"' block.
1224 Without this, the C++ sources could not find strcasestr and the
1225 final linking of notmuch would fail.
1227 Notmuch 0.3 (2010-04-27)
1228 ========================
1229 New command-line features
1230 -------------------------
1231 User-configurable tags for new messages
1233 A new "new.tags" option is available in the configuration file to
1234 determine which tags are applied to new messages. Run "notmuch
1235 setup" to generate new documentation within ~/.notmuch-config on how
1236 to specify this value.
1238 Threads search results named based on subjects that match search
1240 This means that when new mails arrived to a thread you've previously
1241 read, and the new mails have a new subject, you will see that
1242 subject in the search results rather than the old subject.
1244 Faster operation of "notmuch tag" (avoid unneeded sorting)
1246 Since the user just wants to tag all matching messages, we can make
1247 things perform a bit faster by avoiding the sort.
1249 Even Better guessing of From: header for "notmuch reply"
1251 Notmuch now looks at a number of headers when trying to figure out
1252 the best From: header to use in a reply. This is helpful if you have
1253 several configured email addresses, and you also subscribe to various
1254 mailing lists with different addresses, (so that mails you are
1255 replying to won't always include your subscribed address in the To:
1258 Indication of author names that match a search
1260 When notmuch displays threads as the result of a search, it now
1261 lists the authors that match the search before listing the other
1262 authors in the thread. It inserts a pipe '|' symbol between the last
1263 matching and first non-matching author. This is especially useful in
1264 a search that includes tag:unread. Now the authors of the unread
1265 messages in the thread are listed first.
1267 New: Python bindings
1268 --------------------
1269 Sebastian Spaeth has contributed his python bindings for the notmuch
1270 library to the central repository. These bindings were previously
1271 known as "cnotmuch" within python but have now been renamed to be
1272 accessible with a simple, and more official-looking "import notmuch".
1274 The bindings have already proven very useful as people proficient in
1275 python have been able to easily develop programs to do notmuch-based
1276 searches for email-address completion, maildir-flag synchronization,
1279 These bindings are available within the bindings/python directory, but
1280 are not yet integrated into the top-level Makefiles, nor the top-level
1281 package-building scripts. Improvements are welcome.
1283 Emacs interface improvements
1284 ----------------------------
1285 An entirely new initial view for notmuch, (friendly yet powerful)
1287 Some of us call the new view "notmuch hello" but you can get at it
1288 by simply calling "emacs -f notmuch". The new view provides a search
1289 bar where new searches can be performed. It also displays a list of
1290 recent searches, along with a button to save any of these, giving it
1291 a new name as a "saved search". Many people find these "saved
1292 searches" one of the most convenient ways of organizing their mail,
1293 (providing all of the features of "folders" in other mail clients,
1294 but without any of the disadvantages).
1296 Finally, this view can also optionally display all of the tags that
1297 exist in the database, along with a count for each tag, and a custom
1298 search of messages with that tag that's simply a click (or keypress)
1301 Note: For users that liked the original mode of "emacs -f notmuch"
1302 immediately displaying a particular search result, we
1303 recommend instead running something like:
1305 emacs --eval '(notmuch search "tag:inbox" t)'
1307 The "t" means to sort the messages in an "oldest first" order,
1308 (as notmuch would do previously by default). You can also
1309 leave that off to have your search results in "newest first"
1312 Full-featured "customize" support for configuring notmuch
1314 Notmuch now plugs in well to the emacs "customize" mode to make it
1315 much simpler to find things about the notmuch interface that can be
1316 tweaked by the user.
1318 You can get to this mode by starting at the main "Customize" menu in
1319 emacs, then browsing through "Applications", "Mail", and
1320 "Notmuch". Or you can go straight to "M-x customize-group"
1323 Once you're at the customize screen, you'll see a list of documented
1324 options that can be manipulated along with checkboxes, drop-down
1325 selectors, and text-entry boxes for configuring the various
1328 Support for doing tab-completion of email addresses
1330 This support currently relies on an external program,
1331 (notmuch-addresses), that is not yet shipped with notmuch
1332 itself. But multiple, suitable implementations of this program have
1333 already been written that generate address completions by doing
1334 notmuch searches of your email collection. For example, providing
1335 first those addresses that you have composed messages to in the
1338 One such program (implemented in python with the python bindings to
1339 notmuch) is available via:
1341 git clone http://jkr.acm.jhu.edu/git/notmuch_addresses.git
1343 Install that program as notmuch-addresses on your PATH, and then
1344 hitting TAB on a partial email address or name within the To: or Cc:
1345 line of an email message will provide matching completions.
1347 Support for file-based (Fcc) delivery of sent messages to mail store
1349 This isn't yet enabled by default. To enable this, one will have to
1350 set the "Notmuch Fcc Dirs" setting within the notmuch customize
1351 screen, (see its documentation there for details). We anticipate
1352 making this automatic in a future release.
1354 New 'G' key binding to trigger mail refresh (G == "Get new mail")
1356 The 'G' key works wherever '=' works. Before refreshing the screen
1357 it calls an external program that can be used to poll email servers,
1358 run notmuch new and setup specific tags for the new emails. The
1359 script to be called should be configured with the "Notmuch Poll
1360 Script" setting in the customize interface. This script will
1361 typically invoke "notmuch new" and then perhaps several "notmuch
1364 Implement emacs message display with the JSON output from notmuch.
1366 This is much more robust than the previous implementation, (where
1367 some HTML mails and mail quoting the notmuch code with the delimiter
1368 characters in it would cause the parser to fall over).
1370 Better handling of HTML messages and MIME attachments (inline images!)
1372 Allow for any MIME parts that emacs can display to be displayed
1373 inline. This includes inline viewing of image attachments, (provided
1374 the window is large enough to fit the image at its natural size).
1376 Much more robust handling of HTML messages. Currently both text/plain
1377 and text/html alternates will be rendered next to each other. In a
1378 future release, users will be able to decide to see only one or the
1379 other representation.
1381 Each attachment now has its own button so that attachments can be
1382 saved individually (the 'w' key is still available to save all
1385 Customizable support for tidying of text/plain message content
1387 Many new functions are available for tidying up message
1388 content. These include options such as wrapping long lines,
1389 compressing duplicate blank lines, etc.
1391 Most of these are disabled by default, but can easily be enabled by
1392 clicking the available check boxes under the "Notmuch Show Insert
1393 Text/Plain Hook" within the notmuch customize screen.
1395 New support for searchable citations (even when hidden)
1397 When portions of overly-long citations are hidden, the contents of
1398 these citations will still be available for emacs' standard
1399 "incremental search" functions. When the search matches any portion
1400 of a hidden citation, the citation will become visible temporarily
1401 to display the search result.
1403 More flexible handling of header visibility
1405 As an answer to complaints from many users, the To, Cc, and Date
1406 headers of messages are no longer hidden by default. For those users
1407 that liked that these were hidden, a new "Notmuch Messages Headers
1408 Visible" option in the customize interface can be set to nil. The
1409 visibility of headers can still be toggled on a per-message basis
1410 with the 'h' keybinding.
1412 For users that don't want to see some subset of those headers, the
1413 new "Notmuch Message Headers" variable can be customized to list
1414 only those headers that should be present in the display of a message.
1416 The Return key now toggles message visibility anywhere
1418 Previously this worked only on the first summary-line of a message.
1420 Customizable formatting of search results
1422 The user can easily customize the order, width, and formatting of
1423 the various fields in a "notmuch search" buffer. See the "Notmuch
1424 Search Result Format" section of the customize interface.
1426 Generate nicer names for search buffers when using a saved search.
1428 Add a notmuch User-Agent header when sending mail from notmuch/emacs.
1430 New keybinding (M-Ret) to open all collapsed messages in a thread.
1434 Provide a new NOTMUCH_SORT_UNSORTED value for queries
1436 This can be somewhat faster when sorting simply isn't desired. For
1437 example when collecting a set of messages that will all be
1438 manipulated identically, (adding a tag, removing a tag, deleting the
1439 messages), then there's no advantage to sorting the messages by
1444 Fix to compile against GMime 2.6
1446 Previously notmuch insisted on being able to find GMime 2.4, (even
1447 though GMime 2.6 would have worked all along).
1449 Fix configure script to accept (and ignore) various standard options.
1451 For example, those that the Gentoo build scripts expect configure to
1452 accept are now all accepted.
1456 A large number of new tests for the many new features.
1458 Better display of output from failed tests.
1460 Now shows failures with diff rather than forcing the user to gaze at
1461 complete actual and expected output looking for deviation.
1463 Notmuch 0.2 (2010-04-16)
1464 ========================
1465 This is the second release of the notmuch mail system, with actual
1466 detailed release notes this time!
1468 This release consists of a number of minor new features that make
1469 notmuch more pleasant to use, and a few fairly major bug fixes.
1471 We didn't quite hit our release target of "about a week" from the 0.1
1472 release, (0.2 is happening 11 days after 0.1), but we hope to do
1473 better for next week. Look forward to some major features coming to
1474 notmuch in subsequent releases.
1480 Better guessing of From: header.
1482 Notmuch now tries harder to guess which configured address should be
1483 used as the From: line in a "notmuch reply". It will examine the
1484 Received: headers if it fails to find any configured address in To:
1485 or Cc:. This allows it to often choose the correct address even when
1486 replying to a message sent to a mailing list, and not directly to a
1489 Make "notmuch count" with no arguments count all messages
1491 Previously, it was hard to construct a search term that was
1492 guaranteed to match all messages.
1494 Provide a new special-case search term of "*" to match all messages.
1496 This can be used in any command accepting a search term, such as
1497 "notmuch search '*'". Note that you'll want to take care that the
1498 shell doesn't expand * against the current files. And note that the
1499 support for "*" is a special case. It's only meaningful as a single
1500 search term and loses its special meaning when combined with any
1503 Automatically detect thread connections even when a parent message is
1506 Previously, if two or more message were received with a common
1507 parent, but that parent was not received, then these messages would
1508 not be recognized as belonging to the same thread. This is now fixed
1509 so that such messages are properly connected in a thread.
1513 Fix potential data loss in "notmuch new" with SIGINT
1515 One code path in "notmuch new" was not properly handling
1516 SIGINT. Previously, this could lead to messages being removed from
1517 the database (and their tags being lost) if the user pressed
1518 Control-C while "notmuch new" was working.
1520 Fix segfault when a message includes a MIME part that is empty.
1522 Fix handling of non-ASCII characters with --format=json
1524 Previously, characters outside the range of 7-bit ASCII were
1525 silently dropped from the JSON output. This led to corrupted display
1526 of utf-8 content in the upcoming notmuch web-based frontends.
1528 Fix headers to be properly decoded in "notmuch reply"
1530 Previously, the user might see:
1532 Subject: Re: =?iso-8859-2?q?Rozlu=E8ka?=
1536 Subject: Re: Rozlučka
1538 The former text is properly encoded to be RFC-compliant SMTP, will
1539 be sent correctly, and will be properly decoded by the
1540 recipient. But the user trying to edit the reply would likely be
1541 unable to read or edit that field in its encoded form.
1543 Emacs client features
1544 ---------------------
1545 Show the last few lines of citations as well as the first few lines.
1547 It's often the case that the last sentence of a citation is what is
1548 being replied to directly, so the last few lines are often much more
1549 important. The number of lines shown at the beginning and end of any
1550 citation can be configured, (notmuch-show-citation-lines-prefix and
1551 notmuch-show-citation-lines-suffix).
1553 The '+' and '-' commands in the search view can now add and remove
1556 Selective bulk tagging is now possible by selecting a region of
1557 threads and then using either the '+' or '-' keybindings. Bulk
1558 tagging is still available for all threads matching the current
1559 search with the '*' binding.
1561 More meaningful buffer names for thread-view buffers.
1563 Notmuch now uses the Subject of the thread as the buffer
1564 name. Previously it was using the thread ID, which is a meaningless
1567 Provide for customized colors of threads in search view based on tags.
1569 See the documentation of notmuch-search-line-faces, (or us "M-x
1570 customize" and browse to the "notmuch" group within "Applications"
1571 and "Mail"), for details on how to configure this colorization.
1573 Build-system features
1574 ---------------------
1575 Add support to properly build libnotmuch on Darwin systems (OS X).
1577 Add support to configure for many standard options.
1579 We include actual support for:
1581 --includedir --mandir --sysconfdir
1583 And accept and silently ignore several more:
1585 --build --infodir --libexecdir --localstatedir
1586 --disable-maintainer-mode --disable-dependency-tracking
1588 Install emacs client in "make install" rather than requiring a
1589 separate "make install-emacs".
1591 Automatically compute versions numbers between releases.
1593 This support uses the git-describe notation, so a version such as
1594 0.1-144-g43cbbfc indicates a version that is 144 commits since the
1595 0.1 release and is available as git commit "43cbbfc".
1597 Add a new "make test" target to run the test suite and actually verify
1600 Notmuch 0.1 (2010-04-05)
1601 ========================
1602 This is the first release of the notmuch mail system.
1604 It includes the libnotmuch library, the notmuch command-line
1605 interface, and an emacs-based interface to notmuch.
1607 Note: Notmuch will work best with Xapian 1.0.18 (or later) or Xapian
1608 1.1.4 (or later). Previous versions of Xapian (whether 1.0 or 1.1) had
1609 a performance bug that made notmuch very slow when modifying
1610 tags. This would cause distracting pauses when reading mail while
1611 notmuch would wait for Xapian when removing the "inbox" and "unread"
1612 tags from messages in a thread.
