+New add-on tool: notmuch-mutt
+-----------------------------
+
+The new contrib/ tool `notmuch-mutt` provides Notmuch integration for
+the Mutt mail user agent. Using it, Mutt users can perform mail
+search, thread reconstruction, and mail tagging/untagging without
+leaving Mutt. notmuch-mutt, formerly distributed under the name
+`mutt-notmuch` by Stefano Zacchiroli, will be maintained as a notmuch
+contrib/ from now on.
+
+Library changes
+---------------
+
+The API changes detailed below break binary and source compatibility,
+so libnotmuch has been bumped to version 3.0.0.
+
+The function `notmuch_database_close` has been split into
+`notmuch_database_close` and `notmuch_database_destroy`
+
+ This makes it possible for long running programs to close the xapian
+ database and thus release the lock associated with it without
+ destroying the data structures obtained from it.
+
+`notmuch_database_open`, `notmuch_database_create`, and
+`notmuch_database_get_directory` now return errors
+
+ The type signatures of these functions have changed so that the
+ functions now return a `notmuch_status_t` and take an out-argument for
+ returning the new database object or directory object.
+
+Go bindings changes
+-------------------
+
+Go 1 compatibility
+
+ The go bindings and the `notmuch-addrlookup` utility are now
+ compatible with go 1.
