+- **REMOVED**: `SC.Actions.ActionExecutor.execute_onexit_actions/2` function clause that accepted `%Document{}` as second parameter
 - **BREAKING**: These functions now only accept `%StateChart{}` as the second parameter for proper event queue integration
 - **Migration**: Replace `ActionExecutor.execute_*_actions(states, document)` with `ActionExecutor.execute_*_actions(states, state_chart)`
 - **Benefit**: Action execution now properly integrates with the StateChart event queue system, enabling raised events to be processed correctly
