Dear MySQL users,

MySQL 5.5.24 is a new version of the 5.5 production release of the
world's most popular open source database. MySQL 5.5.24 is recommended
for use on production systems.

MySQL 5.5 includes several high-impact enhancements to improve the
performance and scalability of the MySQL Database, taking advantage of
the latest multi-CPU and multi-core hardware and operating systems. In
addition, with release 5.5, InnoDB is now the default storage engine for
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 Heart Beat
    - Improved usability, with Improved index and table partitioning,
      SIGNAL/RESIGNAL support and enhanced diagnostics, including a new
      Performance Schema monitoring capability.

Changes in MySQL 5.5.24 (2012-May-7)

Functionality Added or Changed

  * Important Change: Replication: INSERT ON DUPLICATE KEY UPDATE
    is now marked as unsafe for statement-based replication if the
    target table has more than one primary or unique key. For more
    information, see Section, "Determination of Safe and
    Unsafe Statements in Binary Logging."

Bugs Fixed

  * Security Fix: Bug #64884 was fixed.

  * InnoDB: Replication: When binary log statements were replayed
    on the slave, the Com_insert, Com_update, and Com_delete
    counters were incremented by BEGIN statements initiating
    transactions affecting InnoDB tables but not by COMMIT
    statements ending such transactions. This affected these
    statements whether they were replicated or they were run using
    mysqlbinlog. (Bug #12662190)

  * If the --bind-address option was given a host name value and
    the host name resolved to more than one IP address, the server
    failed to start. For example, with --bind-address=localhost,
    if localhost resolved to both and ::1, startup
    failed. Now the server prefers the IPv4 address in such cases.
    (Bug #61713, Bug #12762885)

  * mysql_store_result() and mysql_use_result() are not for use
    with prepared statements and are not intended to be called
    following mysql_stmt_execute(), but failed to return an error
    when invoked that way in libmysqld. (Bug #62136, Bug
    References: See also Bug #47485.

  * On Windows, mysqlslap crashed for attempts to connect using
    shared memory. (Bug #31173, Bug #11747181, Bug #59107, Bug
