 ### Recent changes (possibly BC breaking)
 
+* 2014-01 Changed Garbige to Garbage in method names.
+* 2014-02 Qlogin now uses Token model instead of deprecated CodeKey per default.
+* 2014-07 Packagist package name has been renamed to "cakephp-tools".
 * 2014-11 All translations now use the `tools` domain; development messages are not translated anymore
 * 2014-12 Some model validations have also been transformed from generic `validation` into `tools` domain.
-* 2014-12 All `tools` domain translations need to exist in `APP/Locale` due to a core issue in `CakePHP <= 2.5` when trying to overwrite them in the application.
-* 2015-01 With CakePHP2.6 support now we can re-add the Locale files again. Use `App.preferApp` Configure key to overwrite the plugin's locale files.

+## Useful Features
+
+### Debugging
+Use `Configure::write('App.monitorHeader', true);` to assert, that all controller actions don't (accidently) sent any headers prior
+to the actual response->send() call. It will throw an exception in debug mode, and trigger an error in productive mode.
+
+Make sure your AppController extends the Tools plugin MyController.
