+Notmuch 0.29 (UNRELEASED)
+=========================
+
+Command Line Interface
+----------------------
+
+`notmuch show` now supports --body=false and --include-html with
+--format=text
+
+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.
