+version 0.7.1 - localization
+------------------------------------------
+
+Support for localization has been turned on and much improved. Since you
+probably don't want to enable all the available languages, make sure to set
+`default_locale` and `available_locales` in your configuration file.
+
+When deploying via the LEAP platform, these are controlled via
+`default_locale` and `languages` in provider.json.
+
+version 0.7 - rotating DBs
+------------------------------------------
+
+CouchDB is not designed to handle ephemeral data, like sessions, because
+documents are never really deleted (a tombstone document is always kept to
+record the deletion). To overcome this limitation, we now rotate the
+`sessions` and `tokens` databases monthly. The new database names are
+`tokens_XXX` and `sessions_XXX` where XXX is a counter since the epoch that
+increments every month (not a calendar month, but a month's worth of seconds).
+Additionally, nagios checks and `leap test run` now will create and destroy
+test users in the `tmp_users` database, which will get periodically deleted
+and recreated.
