Dear MySQL users,
MySQL Server 5.5.56 is a new version of the 5.5 production release
of the world's most popular open source database. MySQL 5.5.56 is
recommended for use on production systems.
Binary packages for MySQL 5.5.56 are identical to those for MySQL 5.5.55,
except for the version number. The change in 5.5.56 for Bug #25942414 is
applicable only to those who build from source.
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 Heartbeat
- Improved usability, with Improved index and table partitioning,
SIGNAL/RESIGNAL support and enhanced diagnostics, including a new
Performance Schema monitoring capability.

Security Notes
* For the WITH_SSL CMake option, no is no longer a
permitted value or the default value. The default is now
bundled. Consequently, MySQL now is always built with SSL
support. (Bug #25942414)
