New Features

* The ThreadGroup class has new add_timer_args() and
  add_dynamic_timer_args() methods to create timers passing the
  positional and keyword arguments to the callback as a sequence and a
  mapping. This API provides more flexibility for the addition of
  timer control options in the future.

* The ThreadGroup add_timer_args() and add_dynamic_timer_args()
  methods now support passing a stop_on_exception=False argument to
  allow the timer to keep running even when an exception is raised by
  the callback function.

Deprecation Notes

* The "ThreadGroup.cancel()" method is deprecated and will be
  removed in a future major release.

* The API of the ThreadGroup add_timer() and add_dynamic_timer()
  methods has been identified as error-prone when passing arguments
  intended for the callback function. Passing callback arguments in
  this way is now deprecated. Callers should use the new
  add_timer_args() or add_dynamic_timer_args() methods (respectively)
  instead when it is necessary to pass arguments to the timer callback
