This appendix lists the changes in the MySQL source code for version 5.1.0 and later releases. For information about changes in previous versions of the MySQL database software, see the Manual de referencia de MySQL 4.1, which provides coverage of the 3.22, 3.23, 4.0, and 4.1 series of releases.

We are working actively on MySQL 5.0 and 5.1, and provide only critical bugfixes for MySQL 4.1, 4.0, and MySQL 3.23. We update this section as we add new features, so that everybody can follow the development.

Note that we tend to update the manual at the same time we make changes to MySQL. If you find a recent version of MySQL listed here that you can't find on our download page (http://dev.mysql.com/downloads/), it means that the version has not yet been released.

The date mentioned with a release version is the date of the last BitKeeper ChangeSet on which the release was based, not the date when the packages were made available. The binaries are usually made available a few days after the date of the tagged ChangeSet, because building and testing all packages takes some time.
