-Notmuch 0.22 (UNRELEASED)
+Notmuch 0.23 (UNRELEASED)
+=========================
+
+General (Xapian 1.4+)
+---------------------
+
+Compiling against Xapian 1.4 enables several new features.
+
+Support for single argument date: queries
+
+ `date:<expr>` is equivalent to `date:<expr>..<expr>`.
+
+Support for blocking opens
+
+ When opening a database notmuch by default will wait for another
+ process to release a write lock, rather than returning an error.
+
+Support for named queries
+
+ Named queries (also known as 'saved searches') can be defined with a
+ `query:name` format. The expansion of these queries is stored in the
+ database and they can be used from any notmuch client.
+
+Library
+-------
+
+Message property API
+
+ libnotmuch now supports the attachment of arbitrary key-value pairs
+ to messages. These can be used by various tools to manage their
+ private data without polluting the user tag space. They also support
+ iteration of values with the same key or same key prefix.
+
+Bug fix for `notmuch_directory_set_mtime`
+
+ Update cached mtime to match on-disk mtime.
+
+CLI
+---
+
+Support for compile time options
+
+ A group of `built_with` keys is now supported for notmuch
+ config. Initial keys in this group are `compact`, `field_processor`,
+ and `retry_lock`.
+
+Dump/Restore support for configuration information and properties
+
+ Any configuration information stored in the database (initially just
+ named queries) is dumped and restored. Similarly any properties
+ attached to messages are also dumped and restored. Any new
+ information in the dump format is prefixed by '#' to allow existing
+ scripts to ignore it.
+
+Emacs
+-----
+
+Resend messages
+
+ The function `notmuch-show-resend-message` (bound to `b` in show
+ and tree modes) will (attempt to) send current message to new
+ recipients. The headers of the message won't be altered (e.g. `To:`
+ may point to yourself). New `Resent-To:`, `Resent-From:` and so on
+ will be added instead.
+
+Face customization is easier
+
+ New faces `notmuch-tag-unread`, `notmuch-tag-flagged`,
+ `notmuch-tag-deleted`, `notmuch-tag-added`,
+ `notmuch-search-flagged-face` and `notmuch-search-unread-face` are
+ now used by default. Customize `notmuch-faces` to modify them.
+
+Omit User-Agent header by default when sending mail
+
+Ruby Bindings
+-------------
+
+Add support for `notmuch_database_get_all_tags`
+
+Go Bindings
+-----------
+
+Go bindings moved to contrib
+
+Add support for `notmuch_threads_t` and `notmuch_thread_t`
+
+Fixed constant values so they are not all zero anymore
+
+ Previously, it was impossible to open writable database handles,
+ because `DATABASE_MODE_READ_ONLY` and `DATABASE_MODE_READ_WRITE` were
+ both set to zero.
+ The same issue occured with sort modes.
+
+Notmuch 0.22.2 (2016-09-08)
+===========================
+
+Test Suite
+----------
+
+Silence gdb more
+
+ Have gdb write to a log file instead of stdout, hiding some more
+ (harmless) stderr chatter which causes test failures.
+
+Hardcode fingerprint in PGP/MIME tests
+
+ Make the tests more robust against changing GnuPG output formats.
+
+Notmuch 0.22.1 (2016-07-19)
+===========================
+
+Library
+-------
+
+Correct the definition of `LIBNOTMUCH_CHECK_VERSION`.
+
+Document the (lack of) operations permitted on a closed database.
+
+Test Suite
+----------
+
+Fix race condition in dump / restore tests.
+
+Notmuch-Mutt
+------------
+
+Use `env` to locate perl.
+
+Emacs
+-----
+
+Tell `message-mode` mode that outgoing messages are mail
+
+ This makes message-mode configuration behave more predictably.
+
+Respect charset of MIME parts when reading them
+
+ Fix previous assumption that everyone uses UTF-8.
+
+Notmuch 0.22 (2016-04-26)
=========================
General
Notmuch should now build (and the test suite should pass) on recent
releases of Xapian 1.3.x. It has been tested with Xapian 1.3.5.
+Limited support for S/MIME messages
+
+ Signature verification is supported, but not decryption. S/MIME
+ signature creation and S/MIME encryption are supported via built-in
+ support in Emacs. S/MIME support is not extensively tested at this
+ time.
+
+Bug Fixes
+
+ Fix for threading bug involving deleting and re-adding
+ messages. Fix for case-sensitive content disposition headers. Fix
+ handling of 1 character directory names at top level.
+
+Command Line Interface
+----------------------
+
+`notmuch show` now supports verifying S/MIME signatures
+
+ This support relies on an appropriately configured `gpgsm`.
+
Build System
------------
(or, in some cases, displaying an empty buffer and throwing an
error). This also affects re-display of the current thread.
+Handle S/MIME signatures in emacs
+
+ The emacs interface is now capable making and verifying S/MIME
+ signatures.
+
`notmuch-message-address-insinuate` is now a no-op
This reduces the amount of interference with non-notmuch uses of
message-mode.
+Address completion improvements
+
+ An external script is no longer needed for address completion; if
+ you previously configured one, customize the variable
+ `notmuch-address-command` to try the internal completion. If
+ `company-mode` is available, notmuch uses it by default for
+ interactive address completion.
+
+Test and experiment with the emacs MUA available in source tree
+
+ `./devel/try-emacs-mua` runs emacs and fills the window with
+ information how to try the MUA safely. Emacs is configured to use
+ the notmuch (lisp) files located in `./emacs` directory.
+
Documentation
-------------
process already has the write lock the dump will not start, so
script callers should still check the return value.
-`notmuch insert` requires succesful message indexing for success status
+`notmuch insert` requires successful message indexing for success status
Previously the `notmuch insert` subcommand indicated success even if
the message indexing failed, as long as the message was delivered to
file system. This could have lead to delivered messages missing
tags, etc. `notmuch insert` is now more strict, also requiring
- succesful indexing for success status. Use the new `--keep` option
+ successful indexing for success status. Use the new `--keep` option
to revert to the old behaviour (keeping the delivered message file
and returning success even if indexing fails).
