F MySQL change history

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

Note that we tend to update the manual at the same time we make changes to MySQL. If you find a version listed below that you can't find on the MySQL download page, this means that the version has not yet been released!

F.1 Changes in release 4.0.x (Development; Alpha)

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

Our TODO section contains what we plan to have in 4.0. See section 1.6.1 Things that should be in 4.0.

F.1.1 Changes in release 4.0.0

F.2 Changes in release 3.23.x (Stable)

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.
BerkeleyDB or BDB
Uses the Berkeley DB library from Sleepycat Software to implement transaction-safe tables.
InnoDB
A transaction-safe table handler that supports row level locking, and many Oracle-like features.

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 4.0 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.

F.3 Changes in release 3.22.x (Older; Still supported)

The 3.22 version has faster and safer connect code than version 3.21, as well as a lot of new nice enhancements. The reason for not including these changes As there aren't really any MAJOR changes, upgrading from 3.21 to 3.22 should be very easy and painless.
