Released 2019-03-06

- The ``delete_many`` function is now able to ignore any errors and continue
deleting the cache. However, in order to preserve backwards compatibility,
the default mode is to abort the deletion process. In order to use the new
deletion mode, one has to flip the config setting ``CACHE_IGNORE_ERRORS`` to
``True``. This was and still is only relevant for the **filesystem** and
**simple** cache backends.
:pr:`94`
- Re-added the ``gaememcached`` CACHE_TYPE for improved backwards compatibility.
