Release Notes: The project now uses libmemcached. The previous library was causing too many issues, and the new library works quite well. XML row format added, so the engine will now store data in memcached as XML (so the data can be read by both MySQL from memcached and any language that can parse XML). An issue with overwriting keys has been fixed.
Release Notes: Support has been added for packed rows (uses less memory). Support has been fixed for IN() operations. A bug in UPDATE when ORDER BY was given has been fixed.
Release Notes: Table space support was added. The engine can now use multiple memcached servers.
