+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.
