+ `notmuch count` now supports batch operations similar to `notmuch
+ tag`. This is mostly an optimization for remote notmuch usage.
+
+Configuration file saves follow symbolic links
+
+ The notmuch commands that save the configuration file now follow
+ symbolic links instead of overwrite them.
+
+`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.
+
+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.
+
+Top level option to redirect writes to stderr
+
+ With `notmuch --stderr=FILE` all writes to stderr are redirected to
+ the specified file. If FILE is '-', stderr is redirected to stdout.
+
+Deprecated commands "part" and "search-tags" are removed.
+
+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.
+
+Vim Front-End
+-------------
+
+The vim based front end to notmuch is deprecated and moved to contrib.
+We haven't been able to support this as well as we would like, and it
+has accumulated bugs and gaps in functionality. We recommend that
+people packaging notmuch no longer provide binary packages for
+notmuch-vim, but of course that is their decision.
+
+Emacs Interface
+---------------
+
+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.

+
+Notmuch 0.15 (2013-01-18)
+=========================
+
+General
+-------
+
+Date range search support
+
+ The `date:` prefix can now be used in queries to restrict the results
+ to only messages within a particular time range (based on the Date:
+ header) with a range syntax of `date:<since>..<until>`. Notmuch
+ supports a wide variety of expressions in `<since>` and
+ `<until>`. Please refer to the `notmuch-search-terms(7)` manual page
+ for details.
