Long promised by MySQL AB
and long awaited by our users,
MySQL Server 4.0 is now available in production version.
MySQL 4.0 is available for download from http://www.mysql.com/ and from our mirrors. MySQL 4.0 has been tested by a large number of users and is in production use at many large sites.
The major new features of MySQL Server 4.0 are geared toward our existing business and community users, enhancing the MySQL database software as the solution for mission-critical, heavy-load database systems. Other new features target the users of embedded databases.
MySQL Version 4.0.12 was declared stable for production use in March 2003. This means that, in future, only bug fixes will be done for the 4.0 release series and only critical bug fixes will be done for the older 3.23 series. See section 2.5.2 Upgrading From Version 3.23 to 4.0.
New features to the MySQL
software are being added to MySQL 4.1
which is now also available (alpha version).
See section 1.5.2 MySQL 4.1 in a Nutshell.
