This section provides a snapshot of the MySQL development roadmap, including major features implemented in or planned for various MySQL releases. The following sections provide information for each release series.
The current production release series is MySQL 5.0, which was declared stable for production use as of MySQL 5.0.15, released in October 2005. The previous production release series was MySQL 4.1, which was declared stable for production use as of MySQL 4.1.7, released in October 2004. “Production status” means that future 5.0 and 4.1 development is limited only to bugfixes. For the older MySQL 4.0 and 3.23 series, only critical bugfixes are made.
Active MySQL development currently is taking place in the MySQL 5.0 and 5.1 release series; and new features are being added only to the latter.
Before upgrading from one release series to the next, please see the notes in Section 2.11, “Upgrading MySQL”.
