Updates the requirements on cachetools to permit the latest version.

Changelog

v5.1.0 (2022-05-15)

Add cache decorator parameters as wrapper function attributes.

v5.0.0 (2021-12-21)

Require Python 3.7 or later (breaking change).

Remove deprecated submodules (breaking change).

The cache, fifo, lfu, lru, mru, rr and ttl submodules have been deleted. Therefore, statements like

from cachetools.ttl import TTLCache

will no longer work. Use

from cachetools import TTLCache

instead.

Pass self to @cachedmethod key function (breaking change).

The key function passed to the @cachedmethod decorator is now called as key(self, *args, **kwargs).

The default key function has been changed to ignore its first argument, so this should only affect applications using custom key functions with the @cachedmethod decorator.

Change exact time of expiration in TTLCache (breaking change).

TTLCache items now get expired if their expiration time is less than or equal to timer(). For applications using the default timer(), this should be barely noticable, but it may affect the use of custom timers with larger tick intervals. Note that this also implies that a TTLCache with ttl=0 can no longer hold any items, since they will expire immediately.

Change Cache.__repr__() format (breaking change).

String representations of cache instances now use a more compact and efficient format, e.g.

LRUCache({1: 1, 2: 2}, maxsize=10, currsize=2)

Add TLRU cache implementation.
