Bernhard blogged over at http://ocklin.blogspot.com/2010/02/mysql-cluster-711-is-there.html that MySQL Cluster 7.1.1 Beta has been released. The big feature (from my point of view) is the SQL interface on top of NDB$INFO. This means there is now full infrastructure from the NDB data nodes right out to SQL in the MySQL Server for adding monitoring to any bit of the internals of the data nodes.
