-Notmuch 0.27 (UNRELEASED)
+Notmuch 0.30 (2020-06-01)
=========================
+S/MIME
+------
+
+Handle S/MIME (PKCS#7) messages -- one-part signed messages, encrypted
+messages, and multilayer messages. Treat them symmetrically to
+OpenPGP messages. This includes handling protected headers
+gracefully.
+
+If you're using Notmuch with S/MIME, you currently need to configure
+gpgsm appropriately.
+
+Mixed-up MIME Repair
+--------------------
+
+Detect and automatically repair a common form of message mangling
+created by Microsoft Exchange (see index.repaired=mixedup in
+notmuch-properties(7)).
+
+Protected Headers
+-----------------
+
+Avoid indexing the legacy-display part of an encrypted message that
+has protected headers (see
+index.repaired=skip-protected-headers-legacy-display in
+notmuch-properties(7)).
+
+Python
+------
+
+Drop support for python2, focus on python3.
+
+Introduce new CFFI-based python bindings in the python module named
+"notmuch2". Officially deprecate (but still support) the older
+"notmuch" module.
+
+Dependencies
+------------
+
+Support for Xapian 1.2 is removed. The minimum supported version of
+Xapian is now 1.4.0.
+
+Notmuch 0.29.3 (2019-11-27)
+===========================
+
+General
+-------
+
+Fix for use-after-free in notmuch_config_list_{key,val}.
+
+Fix for double close of file in notmuch-dump.
+
+Debian
+------
+
+Drop python2 support from shipped debian packaging.
+
+Notmuch 0.29.2 (2019-10-19)
+===========================
+
+General
+-------
+
+Fix for file descriptor leak when opening gzipped mail files. Thanks
+to James Troup for the bug report and the fix.
+
+Notmuch 0.29.1 (2019-06-11)
+===========================
+
+Build
+-----
+
+Fix for installation failure with `configure --without-emacs`.
+
+Notmuch 0.29 (2019-06-07)
+=========================
+
+General
+-------
+
+Add "body:" field to allow searching for terms that occur only in the
+message body. Users will need to reindex their mail to take advantage
+of this feature.
+
+Add support for indexing user specified headers (e.g. List-Id). See
+notmuch-config(1) for details. This requires reindexing after changing
+the set of headers to be indexed.
+
+Fix bug for searching in some headers for Xapian keywords in quoted
+strings.
+
+Add support for gzip compressed mail messages (/not/ multi-message
+mboxes); e.g. `gzip -9 $MAIL/archive/giant-message && notmuch new`
+should work. Note that maildir flag syncing for gzipped messages is
+currently untested.
+
+Notmuch is now capable of indexing, searching and rendering
+cryptographically-protected Subject: headers of the form produced by
+Enigmail and K-9 mail in encrypted messages.
+
+Command Line Interface
+----------------------
+
+`notmuch show` now supports --body=false and --include-html with
+--format=text
+
+Fix several performance problems with `notmuch reindex`.
+
+`notmuch show` and `notmuch reply` now emit per-message cryptographic
+status in their json and sexp output formats. See devel/schemata for
+more details about what is included there. This status includes
+information about cryptographic protections for the Subject header.
+
+Emacs
+-----
+
+Optionally check for missing attachements in outgoing messages (see
+function `notmuch-mua-attachment-check`).
+
+Bind `B` to browse URLs in current message.
+
+Bind `g` to refresh the current notmuch buffer.
+
+Editing a message as new now includes an FCC header.
+
+Forwarded messages are now tagged as +forwarded (customizable).
+
+Add references header to link forwarded message to thread of original
+message.
+
+The minimum supported major version of Emacs is now 24.
+
+Support for GNU Emacs older than 25.1 is deprecated with this release,
+and may be removed in a future release.
+
+Notmuch-emacs documentation is somewhat expanded. More contributions
+are very welcome.
+
+Build System
+------------
+
+Notmuch release tarballs are now compressed with `xz`.
+
+We now provide conventional detached signatures of the release
+tarballs in addition to the signed `sha256sum` files.
+
+Dependencies
+------------
+
+Support for GMime 2.6 is removed. The minimum supported version of
+GMime is now 3.0.3. GMime also needs to have been compiled with
+cryptography support.
+
+Test Suite
+----------
+
+If either GNU parallel or moreutils parallel is installed, the tests
+in the test suite will now be run in parallel (one per available
+core). This can be disabled with NOTMUCH_TEST_SERIALIZE=1.
+
+Notmuch 0.28.4 (2019-05-05)
+===========================
+
+Command line interface
+----------------------
+
+Fix a spurious error when using `notmuch show --raw` on messages whose
+size is a multiple of the internal buffer size.
+
+Notmuch 0.28.3 (2019-03-05)
+===========================
+
+Library
+-------
+
+Fix a bug with the internal data structure _notmuch_string_map_t used
+by message properties.
+
+Build System
+------------
+
+Serialize calls to sphinx-build to avoid race condition.
+
+Notmuch 0.28.2 (2019-02-17)
+===========================
+
+Emacs
+-----
+
+Invoke gpg with --batch and --no-tty.
+
+Python Bindings
+---------------
+
+Fix documentation build with Python 3.7. Note that Python >= 3.3 is
+now needed to build this documentation.
+
+Notmuch 0.28.1 (2019-02-01)
+===========================
+
+Build System
+------------
+
+`configure` no longer uses the special variable BASH, as this causes
+problems on systems where /bin/sh is bash.
+
+Notmuch 0.28 (2018-10-12)
+=========================
+
+General
+-------
+
+Improve threading
+
+ The threading algorithm has been updated to consider all references,
+ not just the heuristically chosen parent (e.g. when that parent is
+ not in the database). The heuristic for choosing a parent message
+ has also been updated to again consider the In-Reply-To header, if
+ it looks sensible. Re-indexing might be needed to take advantage of
+ the latter change.
+
+Handle mislabelled Windows-1252 parts
+
+ Messages that contain Windows-1252 are apparently frequently
+ mislabelled as ISO 8859-1. Use GMime functionality to apply the
+ correct encoding for such messages.
+
+Command Line Interface
+----------------------
+
+Support relative database paths
+
+ Database paths (i.e. parameters to `notmuch config set
+ database.path`) without a leading `/` are now interpreted relative
+ to $HOME of the invoking user.
+
+Emacs
+-----
+
+Improve stderr handling
+
+ Add a real sentinel process to clean up stderr buffer. This is
+ needed on e.g. macOS.
+
+Call `notmuch-mua-send-hook` hooks when sending a message
+
+ This hook was documented, but not functional for a very long time.
+
+Completion
+----------
+
+The zsh completion has been updated to cover most of the notmuch
+CLI. Internally it uses regexp searching, so needs at least Notmuch
+0.24.
+
+Build System
+------------
+
+The build system now installs notmuch-mutt and notmuch-emacs-mua with
+absolute shebangs, following the conventions of most Linux
+distributions.
+
+Test Suite
+----------
+
+Fix certain tests that were failing with GMime 2.6. Users are reminded
+that support for versions of GMime before 3.0.3 has been deprecated
+since Notmuch 0.25.
+
+Notmuch 0.27 (2018-06-13)
+=========================
+
+General
+-------
+
+Add support for thread:{} queries
+
+ Queries of the form `thread:{foo} and thread:{bar}` match threads
+ containing (possibly distinct) messages matching foo and bar. See
+ `notmuch-search-terms(7)` for details.
+
+Command Line Interface
+----------------------
+
+Add the --full-scan option to `notmuch new`
+
+ This option disables mtime based optimization of scanning for new mail.
+
+Add new --decrypt=stash option for `notmuch show`
+
+ This facilitates a workflow for encrypted messages where message
+ cleartext are indexed on first read, but the user's decryption key
+ does not have to be available during message receipt.
+
+Documentation
+-------------
+
+An initial manual for `notmuch-emacs` is now installed by default (in
+`info` format).
+
+Dependencies
+------------
+
+As of this release, support for versions of Xapian before 1.4.0 is
+deprecated, and may disappear in a future release of notmuch.
+
Notmuch 0.26.2 (2018-04-28)
===========================
Library Changes
---------------
-Work around Xapian bug with `get_mset(0,0, x)`.
+Work around Xapian bug with `get_mset(0,0, x)`
This causes aborts in `_notmuch_query_count_documents` on
e.g. Fedora 28. The underlying bug is fixed in Xapian commit
Transition `notmuch_database_add_message` to `notmuch_database_index_file`
- When indexing an e-mail message, the new
- `notmuch_database_index_file` function is the preferred form, and
- the old `notmuch_database_add_message` is deprecated. The new form
- allows passing a set of options to the indexing engine, which the
- operator may decide to change from message to message.
