D. MySQL Change History

This appendix lists the changes from version to version in the MySQL source code.

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

Our TODO section contains what further plans we have for 4.1 & 5.0. See section MySQL and The Future (The TODO).

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

The date mentioned with a release version is the date of the last BitKeeper ChangeSet that this particular release has been based on, not the date when the packages have been made available. The binaries are usually made available a few days after the date of the tagged ChangeSet - building and testing all packages takes some time.


D.1 Changes in release 5.0.0 (Development)

For the time being, version 5.0 is only available in source code. See section Installing from the Development Source Tree.

D.3.17 Changes in release 4.0.0 (Oct 2001: Alpha)


D.4 Changes in release 3.23.x (Recent; still supported)

Please note that since release 4.0 is now production level, only critical fixes are done in the 3.23 release series. You are recommended to upgrade when possible, to take advantage of all speed and feature improvements in 4.0. See section Upgrading From Version 3.23 to 4.0.

The 3.23 release has several major features that are not present in previous versions. We have added three new table types:

MyISAM

A new ISAM library which is tuned for SQL and supports large files.

InnoDB

A transaction-safe storage engine that supports row level locking, and many Oracle-like features.

BerkeleyDB or BDB

Uses the Berkeley DB library from Sleepycat Software to implement transaction-safe tables.

Note that only MyISAM is available in the standard binary distribution.

The 3.23 release also includes support for database replication between a master and many slaves, full-text indexing, and much more.

All new features are being developed in the 4.x version. Only bug fixes and minor enhancements to existing features will be added to 3.23.

The replication code and BerkeleyDB code is still not as tested and as the rest of the code, so we will probably need to do a couple of future releases of 3.23 with small fixes for this part of the code. As long as you don't use these features, you should be quite safe with MySQL 3.23!

Note that the above doesn't mean that replication or Berkeley DB don't work. We have done a lot of testing of all code, including replication and BDB without finding any problems. It only means that not as many users use this code as the rest of the code and because of this we are not yet 100% confident in this code.
