+* Fix: RowScanner errors are fatal to Rows
+* Fix: Enable failover efforts when pg_hba.conf disallows non-ssl connections (Brandon Kauffman)
+* Hstore text codec internal improvements (Evan Jones)
+* Fix: Stop timers for background reader when not in use. Fixes memory leak when closing connections (Adrian-Stefan Mares)
+* Fix: Stop background reader as soon as possible.
+* Add PgConn.SyncConn(). This combined with the above fix makes it safe to directly use the underlying net.Conn.
