About MySQL
The world’s most popular open source database. Its architecture makes it extremely fast and easy to customize. Extensive reuse of code within the software and a minimalistic approach to producing functionally-rich features has resulted in a database management system unmatched in speed, compactness, stability, and ease of deployment.

The unique separation of the core server from the storage engine makes it possible to run with strict transaction control or with ultra-fast transactionless disk access, whichever is most appropriate for the situation.

What’s New in this Version
- Important Change: Replication: RESET MASTER and RESET SLAVE now reset the values shown for Last_IO_Error, Last_IO_Errno, Last_SQL_Error, and Last_SQL_Errno in the output of SHOW SLAVE STATUS.
- The libedit library was upgraded to version 2.11.
- Security Fix: Using an XPath expression employing a scalar expression as a FilterExpr with ExtractValue() or UpdateXML() caused the server to crash. Such expressions now cause an error instead.
- Many more enhancements.
