- New function: Engine::track_vetoed_activities() to interrupt run()
when an activity fails to start, and to keep track of such activities.
Please see the corresponding example for more info.
+ - Introduce on_X_cb() functions for all signals, to attach a new
+ callback to the signal X. The signal variables are now hidden and
+ only these functions should be used.
+ Rational: this enables the usual deprecation schema where functions
+ remain for 4 releases when we need to modify the signals, while the
+ current code with the signal variables directly visible prevent any
+ smooth transition.
