Release Notes

tkem/cachetools (cachetools)

v6.2.1

Compare Source

===================

• Add support for Python 3.14.

• Improve documentation.

• Update CI environment.

v6.2.0

Compare Source

===================

• Improve general RRCache performance by storing cache keys in an
  additional sequence container. Note that this will increase memory
  consumption.

• Add more unit tests.

v6.1.0

Compare Source

===================

• Improve LFUCache insertion performance by switching to an
  implementation based on the cacheing <https://pypi.org/project/cacheing/>_ library.

• Update CI environment.

v6.0.0

Compare Source

===================

• Require Python 3.9 or later (breaking change).

• Remove MRUCache and the @func.mru_cache decorator (breaking
  change).

• Add an optional condition parameter to the @cached and
  @cachedmethod decorators, which, when used with a
  threading.Condition instance, should improve cache stampede <https://en.wikipedia.org/wiki/Cache_stampede>_ issues in massively
  parallel environments. Note that this will inflict some performance
  penalty, and therefore has to be enabled explicitly.

• Convert the cachetools.func decorators to use a
  threading.Condition instance to deal with cache stampede <https://en.wikipedia.org/wiki/Cache_stampede>_ issues. Note that
  this may result in a noticable performance degradation, depending
  on your actual use case.

• Deprecate support for cache(self) returning None to suppress
  caching with the @cachedmethod decorator.

• Improve documentation.

• Update CI environment.

Hey folks! I just ran into a blocker due to this dependency being out of date and came here to see it it could be updated and found there is already a recent renovate PR for exactly that! If this can be merged and a release pushed it would be a huge help. Thanks!
