+Command-Line Interface
+----------------------
+
+There is a new `mimetype:` search prefix
+
+ The new `mimetype:` search prefix allows searching for the
+ content-type of attachments, which is now indexed. See the
+ `notmuch-search-terms` manual page for details.
+
+Documentation
+-------------
+
+Support for using rst2man in place of sphinx to build the
+docmumentation has been removed.
+
+Contrib
+-------
+
+`notmuch-deliver` is removed. As far as we know, all functionality
+previously provided by `notmuch-deliver` should now be provided by
+`notmuch insert`, provided by the main notmuch binary.
+
+nmbug-status
+------------
+
+`nmbug-status` now only matches local branches when reading
+`status-config.json` from the `config` branch of the `NMBGIT`
+repository. To help new users running `nmbug-status`, `nmbug clone`
+now creates a local `config` branch tracking `origin/config`. Folks
+who use `nmbug-status` with an in-Git config (i.e. you don't use the
+`--config` option) who already have `NMBGIT` set up are encouraged to
+run:
+
+ git checkout config origin/config
+
+in their `NMBGIT` repository (usually `~/.nmbug`).
+
+Notmuch 0.19 (2014-11-14)
+=========================
+
+Overview
+--------
+
+This release improves the reliability of `notmuch dump` and the error
+handling for `notmuch insert`. The new `notmuch address` command is
+intended to make searching for email addresses more convenient. At the
+library level the revised handling of missing messages fixes at least
+one bug in threading. The release also includes several interface
+improvements to the emacs interface, most notably the ability to bind
+keyboard shortcuts to saved searches.
+
+Command-Line Interface
+----------------------
+
+Stopped `notmuch dump` failing if someone writes to the database
+
+ The dump command now takes the write lock when running. This
+ prevents other processes from writing to the database during the
+ dump which would cause the dump to fail. Note, if another notmuch
+ 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
+
+ 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
+ to revert to the old behaviour (keeping the delivered message file
+ and returning success even if indexing fails).
+
+`notmuch insert` has gained support for `post-insert` hook
+
+ The new `post-insert` hook is run after message delivery, similar to
+ `post-new`. There's also a new option `notmuch insert --no-hooks` to
+ skip the hook. See the notmuch-hooks(1) man page for details.
+
+`notmuch deliver` is deprecated
+
+ With this release we believe that `notmuch insert` has reached
+ parity with `notmuch deliver`. We recommend that all users of
+ `notmuch deliver` switch to `notmuch insert` as the former is
+ currently unmaintained.
+
+`notmuch search` now supports `--duplicate=N` option with `--output=messages`
+
+ Complementing the `notmuch search --duplicate=N --output=files`
+ options, the new `--duplicate=N --output=messages` combination
+ limits output of message IDs to messages matching search terms that
+ have at least `N` files associated with them.
+
+Added `notmuch address` subcommand
+
+ This new subcommand searches for messages matching the given search
+ terms, and prints the addresses from them. Duplicate addresses are
+ filtered out. The `--output` option controls which of the following
+ information is printed: sender addresses, recipient addresses and
+ count of duplicate addresses.
