* If there is no match for the third party applications; activate the "core" applications needed, enable the Approved/Experiments Experimental applications as needed. Please remember Approved/Experiments Experimental applications that do not work will take time for the authors to update for the new release version.* Enable required "core" and Approved/Experiments Experimental applications "one-at-a-time", testing each application. Stop at any behaviour that is not the same, this usually happens with Approved/Experiments Experimental applications (there maybe new versions that have to be installed).
