and crash recovery by default.

MySQL 5.5 also provides a number of additional enhancements including:

   - Significantly improved performance on Windows, with various
     Windows specific features and improvements
   - Higher availability, with new semi-synchronous replication and
     Replication Heartbeat
   - Improved usability, with Improved index and table partitioning,
     SIGNAL/RESIGNAL support and enhanced diagnostics, including a new
     Performance Schema monitoring capability.

        column of the INFORMATION_SCHEMA.PARTITIONS table now shows the
        correct partition creation time for a partition of partitioned
        InnoDB tables.  The UPDATE_TIME column of the
        INFORMATION_SCHEMA.TABLES table now shows when a partitioned
        InnoDB table was last updated by an INSERT, DELETE, or UPDATE.
