+Notmuch 0.9 (2011-10-01)
+========================
+
+New, general features
+---------------------
+
+Correct handling of interruptions during "notmuch new"
+
+ "notmuch new" now operates as a series of small, self-consistent
+ transactions, so it can correctly resume after an interruption or
+ crash. Previously, interruption could lose existing tags, fail to
+ detect messages on resume, or leave the database in a state
+ temporarily or permanently inconsistent with the mail store.
+
+Library changes
+---------------
+
+New functions
+
+ notmuch_database_begin_atomic and notmuch_database_end_atomic allow
+ multiple database operations to be performed atomically.
+
+ notmuch_database_find_message_by_filename does exactly what it says.
+
+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)
+ - Update for n_d_find_message* API changes (see above).
+
+Ruby bindings changes
+---------------------
+
+ - Wrap new library functions notmuch_database_{begin,end}_atomic.
+ - Add new exception Notmuch::UnbalancedAtomicError.
+ - Rename destroy to destroy! according to Ruby naming conventions.
+ - Update for n_d_find_message* API changes (see above).
+
+Emacs improvements
+------------------
+
+ * Add gpg callback to crypto sigstatus buttons to retrieve/refresh
+ signing key.
+ * Add notmuch-show-refresh-view function (and corresponding binding)
+ to refresh the view of a notmuch-show buffer.
+
+Reply formatting cleanup
+------------------------
+
+ "notmuch reply" no longer includes notification that non-leafnode
+ MIME parts are being suppressed.
