 -  Partially fixed a bug (#261) - UTF-8 class method ``clean_string()`` generating log messages and/or not producing the desired result due to an upstream bug in iconv.
 -  Fixed a bug where ``CI_Xmlrpcs::parseRequest()`` could fail if ``$HTTP_RAW_POST_DATA`` is not populated.
 -  Fixed a bug in :doc:`Zip Library <libraries/zip>` internal method ``_get_mod_time()`` where it was not parsing result returned by ``filemtime()``.
+-  Fixed a bug (#3161) - :doc:`Cache Library <libraries/cache>` methods `increment()`, `decrement()` didn't auto-create non-existent items when using redis and/or file storage.
