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.
deprecations:
- |
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 function.
