I had been using FSMOwner.currentStateName prior to 2.6.3. What would be the correct replacement? (not sure is that currentRootStateName, currentDeepStateName, or something else).
It has been replaced with FSMOwner.currentRootStateName to get the state name of the root FSM only, or FSMOwner.currentDeepStateName to get the state name also including the current active SubFSM if any.
The identical to what was there prior to 2.6.3, is the first one, FSMOwner.currentRootStateName.
