1.6. MySQL Development Roadmap
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 is currently 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 2.10, “Upgrading MySQL”.
The most requested features and the versions in which they were
implemented or are scheduled for implementation are summarized in
the following table:
||3.23 (for the
InnoDB storage engine)
||4.1 (for the
MyISAM storage engine)
||5.2 (implemented in 3.23 for
||5.0 and 5.1
