This file describes the needed changes when upgrading from 1.0 to 1.1
The bundle now requires Symfony 2.1 and the 2.3 version of the Gedmo extensions (which is the master branch at the time of this writing)
The bundle no longer duplicates the entities provided by the extensions to make the maintenance easier. You need to configure the mapping explicitly for the extensions as DoctrineBundle cannot guess it. See the updated documentation about registering the mapping for the way to register them.
