Upgrading from Kohana

If you were using 3.3.x version, there are 4 breaking changes that may affect you, be aware.

Kohana_Kohana_Exception, all functions that received parameter Exception $e have been replaced to just $e. If you are extending the class verify you have the same.
Kohana_URL, now function site has a new parameter $subdomain = NULL, if you are extending the class and this function add it.
Module encrypt, now encryption works as a module, if you are using new Encrypt or similar you need to enable the module in your bootstrap ex: 'encrypt' => MODPATH.'encrypt',
MySQL driver has been removed. If you are still using it, please install MySQLi driver and then edit your config/database.php and then set as 'type' => 'MySQLi'
