Seems like a very misleading title. Surly it should be "MySQL now supports the memcache protocol for simple NoSQL-style access on InnoDB tables".

As far as I can make out, the memcached server software itself is not included in MySQL right?

SELF CORRECTION:

No, it does seem to include memcached as well for write through caching. Interesting. http://dev.mysql.com/doc/refman/5.6/en/innodb-memcached-bene...
