Changelog

v0.16.0 (2023-12-22)

  • Add Cache.on_get callback hook. Thanks uncle-lv!
  • Add Cache.on_set callback hook. Thanks uncle-lv!

v0.15.0 (2023-11-03)

  • Add cache statistics. Thanks uncle-lv!
  • Add Cache.get_ttl. Thanks uncle-lv!
  • Add Cache.on_delete callback hook. Thanks uncle-lv!
  • Add support for Python 3.11 and 3.12.

v0.14.1 (2022-08-16)

  • Set minimum Python version to 3.7 in setup.cfg.

v0.14.0 (2022-08-16)

  • Add support for Python 3.10.
  • Drop support for Python 3.6. Minimum supported version is 3.7.
  • Clarify docs around TTL to make it explicit what time units it uses by default.

v0.13.1 (2021-04-28)

  • Minor optimization in Cache.get_many|delete_many.

v0.13.0 (2021-04-27)

  • Add cache_key attribute to memoized functions that can be used to generate the cache key used for a given set of function arguments. Thanks johnbergvall!
  • Fix bug in Cache.full that would result in an exception if cache created with maxsize=None like Cache(maxsize=None). Thanks AllinolCP!
  • Fix bug in Cache.get_many that resulted in RuntimeError: OrderedDict mutated during iteration when cache keys expire during the get_many call.
  • Remove default argument from Cache.get_many. A default value on missing cache key was only ever returned if a list of keys was passed in and those keys happened to expire during the get_many call. breaking change

v0.12.1 (2021-04-19)

  • Fix regression in 0.12.0 that resulted in missing docstrings for some methods of LFUCache and LRUCache.

v0.12.0 (2021-04-19)

  • Fix bug in Cache.__contains__ where it would return True for an expired key.
  • Add type annotations.
  • Add official support for Python 3.8 and 3.9.
  • Drop support for Python 3.4 and 3.5.

  • Fix bug in LFUCache that would result cache growing beyond maxsize limit.

v0.11.1 (2019-01-09)

  • Fix issue with asyncio support in memoization decorators that caused a RuntimeError: await wasn't used with future when certain types of async functions were used inside the memoized function.

v0.11.0 (2018-10-19)

  • Add asyncio support to memoization decorators so they can decorate coroutines.

v0.10.3 (2018-08-01)

  • Support Python 3.7.

v0.10.0 (2018-04-03)

  • Add default argument to Cache() that can be used to override the value for default in Cache.get().

v0.9.0 (2018-03-31)
