+API changes
+
+ notmuch_database_find_message (and n_d_f_m_by_filename) now return
+ a status indicator and uses an output parameter for the
+ message. This change required changing the SONAME of libnotmuch to
+ libnotmuch.so.2
+
+Python bindings changes
+-----------------------
+
+ - Re-encode python unicode objects to utf-8 before passing back to
+ libnotmuch.
+ - Support Database().begin_atomic()/end_atomic()
+ - Support Database().find_message_by_filename()
+ NB! This needs a db opened in READ-WRITE mode currently, or it will crash
+ the python process. The is a limitation (=bug) of the underlying libnotmuch.
+ - Fixes where we would not throw NotmuchErrors when we should (Justus Winter)
