Changelog
=========

New in version 3.0.0 (unreleased)
---------------------------------

* Validate integer inputs for ``expire``, ``delay``, ``incr``, ``decr``, and
  ``memlimit`` -- non-integer values now raise ``MemcacheIllegalInputError``

* The serialization API has been reworked. Instead of consuming a serializer
  and deserializer as separate arguments, client objects now expect an argument
  `serde` to be an object which implements `serialize` and `deserialize`
  as methods. (`serialize` and `deserialize` are still supported but considered
  deprecated)

New in version 2.2.2
--------------------
* Fix ``long_description`` string in Python packaging.

New in version 2.2.1
--------------------
* Fix ``flags`` when setting multiple differently-typed values at once.

New in version 2.2.0
--------------------
* Drop official support for Python 3.4.
* Use ``setup.cfg`` metadata instead ``setup.py`` config to generate package.
* Add ``default_noreply`` parameter to ``HashClient``.
* Add ``encoding`` parameter to ``Client`` constructors (defaults to ``ascii``).
* Add ``flags`` parameter to write operation methods.
* Handle unicode key values in ``MockMemcacheClient`` correctly.
* Improve ASCII encoding failure exception.
