+Notmuch 0.16 (2013-08-03)
+=========================
+
+Command-Line Interface
+----------------------
+
+### Support for delivering messages to Maildir
+
+There is a new command `insert` that adds a message to a Maildir
+folder and notmuch index.
+
+### `notmuch count --batch` option
+
+`notmuch count` now supports batch operations similar to `notmuch
+tag`. This is mostly an optimization for remote notmuch usage.
+
+### `notmuch tag` option to remove all tags from matching messages
+
+`notmuch tag --remove-all` option has been added to remove all tags
+from matching messages. This can be combined with adding new tags,
+resulting in setting (rather than modifying) the tags of the
+messages.
+
+### Decrypting commands explicitly expect a gpg-agent
+
+Decryption in `notmuch show` and `notmuch reply` has only ever
+worked with a functioning gpg-agent. This is now made explicit in
+code and documentation. The functional change is that it's now
+possible to have gpg-agent running, but gpg "use-agent"
+configuration option disabled, not forcing the user to use the agent
+everywhere.
+
+### Configuration file saves follow symbolic links
+
+The notmuch commands that save the configuration file now follow
+symbolic links instead of overwrite them.
+
+### Top level option to specify configuration file
+
+It's now possible to specify the configuration file to use on the
+command line using the `notmuch --config=FILE` option.
+
+### Bash command-line completion
+
+The notmuch command-line completion support for the bash shell has
+been rewritten. Supported completions include all the notmuch
+commands, command-line arguments, values for keyword arguments,
+search prefixes (such as "subject:" or "from:") in all commands that
+use search terms, tags after + and - in `notmuch tag`, tags after
+"tag:" prefix, user's email addresses after "from:" and "to:"
+prefixes, and config options (and some config option values) in
+`notmuch config`. The new completion support depends on the
+bash-completion package.
+
+Deprecated commands "part" and "search-tags" are removed.
+
+Emacs Interface
+---------------
+
+### New keymap to view/save parts; removed s/v/o/| part button bindings
+
+The commands to view, save, and open MIME parts are now prefixed
+with "." (". s" to save, ". v" to view, etc) and can be invoked with
+point anywhere in a part, unlike the old commands, which were
+restricted to part buttons. The old "s"/"v"/"o"/"|" commands on
+part buttons have been removed since they clashed with other
+bindings (notably "s" for search!) and could not be invoked when
+there was no part button. The new, prefixed bindings appear in
+show's help, so you no longer have to memorize them.
+
+### Default part save directory is now `mm-default-directory`
+
+Previously, notmuch offered to save parts and attachments to a mix
+of `mm-default-directory`, `mailcap-download-directory`, and `~/`.
+This has been standardized on `mm-default-directory`.
+
+### Key bindings for next/previous thread
+
+Show view has new key bindings M-n and M-p to move to the next and
+previous thread in the search results.
+
+### Better handling of errors in search buffers
+
+Instead of interleaving errors in search result buffers, search mode
+now reports errors in the minibuffer.
+
+### Faster search and show
+
+Communication between Emacs and the notmuch CLI is now more
+efficient because it uses the CLI's S-expression support. As a
+result, search mode should now fill search buffers faster and
+threads should show faster.
+
+### No Emacs 22 support
+
+The Emacs 22 support added late 2010 was sufficient only for a short
+period of time. After being incomplete for roughly 2 years the code
+in question was now removed from this release.
+
+Vim Front-End
+-------------
+
+The vim based front-end has been replaced with a new one that uses the Ruby
+bindings. The old font-end is available in the contrib subfolder.
+
+Python Bindings
+---------------
+
+Fix loading of libnotmuch shared library on OS X (Darwin) systems.
