## From V2.21 to V2.22 (Boost 1.48)

- eUML: added easier event reprocessing: `process(event_)` and `reprocess()`

- Rewrite of internal transition tables. There were a few bugs (failing recursivity in internal transition tables of sub-sub machines) and a missing feature (unused internal transition table of the main state machine).

- Bugfixes

  - Reverted favor_compile_time policy to Boost 1.46 state

  - `none` event now is convertible from any other event

  - eUML and pseudo exit states

  - Fixed not working Flag_AND

  - Fixed rare bugs causing multiple processing of the same event in a submachine whose transition table contains this event and a base event of it.

  - gcc warnings about unused variables

- Breaking change: the new internal transition table feature causes a minor breaking change. In a submachine, the "Fsm" template parameter for guards / actions of an internal table declared using `internal_transition_table` now is the submachine, not the higher-level state machine. Internal transitions declared using internal rows in the higher-level state machine keep their behavior (the "Fsm" parameter is the higher-level state machine). To sum up, the internal transition "Fsm" parameter is the closest state machine containing this transition.
