========================
* Fix bug with cache_key length calculation.
* Fix bug with how path was set so that its restored properly and propagated.
* Fix bug with CacheMiddleware clobbering enabled setting.
* Update option for ``cookie_expires`` so that it can now handle an integer
which will be used as the seconds till the cookie expires.
* Merge fix for Issue 31, can now handle unicode cache keys.
* Add ``key_length`` option for cache regions, and for keyword args passed
into the cache system. Cache keys longer than this will be SHA'd.
* added runtime beaker.__version__
* Add ``webtest_varname`` option to configuration to optionally include
the session value in the environ vars when using Beaker with WebTest.
* Defer running of pkg_resources to look for external cache modules
until requested. 66
* memcached backend uses pylibmc.ThreadMappedPool to ensure thread-local
usage of pylibmc when that library is in use. (60)
* memcached backend also has ``memcache_module`` string argument, allows
direct specification of the name of which memcache backend to use.
* Basic container/file-based Session support working in Py3K. (72)
* Further Python 3 fixes
* Added an optimization to the FileNamespaceContainer when used with
Session, such that the pickled contents of the file are not
read a second time when session.save() is called. (64)
* Fixed bug whereby CacheManager.invalidate wouldn't work for a function
decorated by cache.cache(). (61)
* cache decorators cache.cache(), cache_region() won't include first
argument named 'self' or 'cls' as part of the cache key. This allows
reasonably safe usage for methods as well as functions. (55)
* file backend no longer squashes unpickling errors. This was inconsistent
behavior versus all the other backends.
* invalidate_corrupt flag on Session now emits a warning. (52)
* cache.remove_value() removes the value even if it's already marked
'expired' (42)
