Dear MySQL users,

MySQL Server 5.5.44 is a new version of the 5.5 production release
of the world's most popular open source database. MySQL 5.5.44 is
recommended for use on production systems.

MySQL 5.5 includes several high-impact enhancements to improve the

the latest multi-CPU and multi-core hardware and operating systems. In

the MySQL Database, delivering ACID transactions, referential integrity
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.
