Edit File: CHANGELOG.rst

v5.5.1 (2025-01-21)
===================

- Add documentation regarding caching of exceptions.

- Officially support Python 3.13.

- Update CI environment.

v5.5.0 (2024-08-18)
===================

- ``TTLCache.expire()`` returns iterable of expired ``(key, value)``
  pairs.

- ``TLRUCache.expire()`` returns iterable of expired ``(key, value)``
  pairs.

- Documentation improvements.

- Update CI environment.

v5.4.0 (2024-07-15)
===================

- Add the ``keys.typedmethodkey`` decorator.

- Deprecate ``MRUCache`` class.

- Deprecate ``@func.mru_cache`` decorator.

- Update CI environment.

v5.3.3 (2024-02-26)
===================

- Documentation improvements.

- Update CI environment.

v5.3.2 (2023-10-24)
===================

- Add support for Python 3.12.

- Various documentation improvements.

v5.3.1 (2023-05-27)
===================

- Depend on Python >= 3.7.

v5.3.0 (2023-01-22)
===================

- Add ``cache_info()`` function to ``@cached`` decorator.

v5.2.1 (2023-01-08)
===================

- Add support for Python 3.11.

- Correct version information in RTD documentation.

- ``badges/shields``: Change to GitHub workflow badge routes.

v5.2.0 (2022-05-29)
===================

- Add ``cachetools.keys.methodkey()``.

- Add ``cache_clear()`` function to decorators.

- Add ``src`` directory to ``sys.path`` for Sphinx autodoc.

- Modernize ``func`` wrappers.

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 noticeable, 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.

- Documentation improvements.

v4.2.4 (2021-09-30)
===================

- Add submodule shims for backward compatibility.
