4.2.0
-----
* added support for connecting to Redis clusters via DSN
* added support for configuring multiple Memcached servers via DSN
* added `MarshallerInterface` and `DefaultMarshaller` to allow changing the serializer and provide one that automatically uses igbinary when available

* now FilesystemAdapter, PhpFilesAdapter, FilesystemCache, PhpFilesCache, PdoAdapter, PdoCache, ChainAdapter, and
ChainCache implement PruneableInterface and support manual stale cache pruning
