+* After $this->response() is called the controller will stop processing.

+### 2.2
+
+* Added config options to set table names for keys, limits and logs.
+* FALSE values were coming out as empty strings in xml or rawxml mode, now they will be 0/1.
+* key => FALSE can now be used to override the keys_enabled option for a specific method, and level is now optional. If no level is set it will assume the method has a level of 0.
+* Fixed issue where calls to ->get('foo') would error is foo was not set. Reported by  Paul Barto.
