         - Make front page cache time configurable.
         - Better working of /fakemapit/ under https.
         - Improve Open311 error output on failing GET requests.
+        - Optionally log failed geocoder searches.
     - Backwards incompatible changes:
         - If you wish the default for the showname checkbox to be checked,
