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

- mysql_upgrade now displays a message indicating the connection parameters it uses when invoking mysqlcheck.
- The mysqltest program now has a move_file from_file to_file command for renaming files.
- Many more enhancements.
