• Require Python 3.9 or later (breaking change).

• RemoveMRUCache and the@func.mru_cache decorator (breakingchange).

• Add an optionalcondition parameter to the@cached and@cachedmethod decorators, which, when used with athreading.Condition instance, should improvecache stampede <https://en.wikipedia.org/wiki/Cache_stampede>_ issues in massivelyparallel environments. Note that this will inflict some performancepenalty, and therefore has to be enabled explicitly.

• Convert thecachetools.func decorators to use athreading.Condition instance to deal withcache stampede <https://en.wikipedia.org/wiki/Cache_stampede>_ issues. Note thatthismay result in a noticable performance degradation, dependingon your actual use case.
