Default port for ndb_mgmd was changed to 1186 (from 2200) as this port number was officially assigned to MySQL Cluster by IANA.

New command in ndb_mgm, PURGE STALE SESSIONS, as a workaround for cases where nodes fail to allocate a node id even if it is free to use.

New command in ndb_mgm, CONNECT.

The ndb executables have been changed to make use of the regular MySQL command line option parsing features. See Section 16.5.5, « Options des commandes pour le cluster MySQL » for notes on changes.

As bonus of the above you can now specify all command line options in my.cnf using the executable names as sections, i.e. [ndbd], [ndb_mgmd], [ndb_mgm], [ndb_restore] etc.

      [ndbd]
      ndb-connectstring=myhost.domain.com:1234
      [ndb_mgm]
      ndb-connectstring=myhost.domain.com:1234

Added use of section [mysql_cluster] in my.cnf. All cluster executables, including mysqld, parse this section. Convenient place to put e.g. ndb-connectstring so that it only needs to be specified once.

Added cluster log info events on allocation and deallocation of nodeid's.

Added cluster log info events on connection refuse as a result of version mismatch.

Extended connectstring syntax to allow for leaving the port number out. E.g. ndb-connectstring|connect-string=myhost1,myhost2,myhost3 is a valid connectstring and connect occurs on default port 1186.

Clear text ndb error messages provided also for error codes that are mapped to corresponding mysql error codes, by executing SHOW WARNINGS after an error has occured which relates to the ndb storage engine.

Significant performance improvements done for read performance, especially for blobs.

Added some variables for performance tuning, ndb_force_send and ndb_use_exact_count. Do show variables like 'ndb%'; in mysql client for listing. Use set command to alter variables.

Added variables to set some options, ndb_use_transactions and ndb_autoincrement_prefetch_sz.
