 +- Issue #23715: :func:`signal.sigwaitinfo` and :func:`signal.sigtimedwait` are
 +  now retried when interrupted by a signal not in the *sigset* parameter, if
 +  the signal handler does not raise an exception. signal.sigtimedwait()
 +  recomputes the timeout with a monotonic clock when it is retried.
 +
 +- Issue #23001: Few functions in modules mmap, ossaudiodev, socket, ssl, and
 +  codecs, that accepted only read-only bytes-like object now accept writable
 +  bytes-like object too.
 +
 +- Issue #23646: If time.sleep() is interrupted by a signal, the sleep is now
 +  retried with the recomputed delay, except if the signal handler raises an
 +  exception (PEP 475).
 +
  - Issue #23136: _strptime now uniformly handles all days in week 0, including
    Dec 30 of previous year.  Based on patch by Jim Carroll.
