+Library changes
+---------------
+
+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 and notmuch_database_create now return errors
+
+ The type signatures of notmuch_database_open and
+ notmuch_database_create have changed so that the functions now
+ return a notmuch_status_t and take an out-argument for returning the
+ new database object.
