+Notmuch replies now include all parts shown in the show view
+
+ There are two main user visible changes. The first is that rfc822
+ parts are now included in replies.
+
+ The second change is that part headers are now included in the reply
+ buffer to provide visible separation of the parts. The choice of
+ which part headers to show is customizable via the variable
+ `notmuch-mua-reply-insert-header-p-function`.
+
+Filtering or Limiting messages is now bound to `l` in the search view
+
+ This binding now matches the analogous binding in show view.

+Notmuch 0.21 (2015-10-29)
+=========================
+
+General
+-------
+
+Notmuch now requires gmime >= 2.6.7. The gmime 2.4 series is no longer
+supported.
+
+Database revision tracking: `lastmod:` queries
+
+ Each message now has a metadata revision number that increases with
+ every tagging operation. See the discussion of `lastmod:` in
+ `notmuch-search-terms(7)` for more information.
+
+Date queries now support `date:<expr>..!` shorthand for
+`date:<expr>..<expr>`
+
+ You can use, for example, `date:yesterday..!` to match from the
+ beginning of yesterday to the end of yesterday. For further details,
+ please refer to the `notmuch-search-terms` manual page.
+
+Notmuch database upgrade to support `lastmod:` queries
+
+ The above mentioned `lastmod:` prefix. This will be done
+ automatically, without prompting on the next time `notmuch new` is
+ run after the upgrade. The upgrade is not reversible, and the
+ upgraded database will not be readable by older versions of
+ Notmuch. As a safeguard, a database dump will be created in the
+ `.notmuch` directory before upgrading.
+
+Build System
+------------
+
+The ruby bindings are now built as part of the main notmuch build
+process. This can be disabled with the `--without-ruby` option to
+configure.
+
+Building the documentation can be disabled with the `--without-docs`
+option to configure.
+
+Skipped individual tests are no longer considered as failures.
+
+Command Line Interface
+----------------------
+
+Database revision tracking
+
+ Two new options were added to support revision tracking. A global
+ option "--uuid" (`notmuch(1)`) was added for to detect counter
+ rollover and reinitialization, and `notmuch-count(1)` gained a
+ `--lastmod` option to query database revision tracking data.
+
+The `notmuch address` command supports new deduplication schemes
+
+ `notmuch address` has gained a new `--deduplicate` option to specify
+ how the results should be deduplicated, if at all. The alternatives
+ are `no` (do not deduplicate, useful for processing the results with
+ external tools), `mailbox` (deduplicate based on the full, case
+ sensitive name and email address), and `address` (deduplicate based
+ on the case insensitive address part). See the `notmuch-address`
+ manual page for further information.

+Emacs Interface
