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 2.6.3, « Passer de la version 3.23 à la version 4.0 ».
The 3.23 release has several major features that are not present in previous versions. We have added three new table types:
A new ISAM library which is tuned for SQL and supports large files.
A transaction-safe storage engine that supports row level locking, and many Oracle-like features.
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
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.
