MySQL 5.0.0 has been released
December 26, 2003[From MySQL AB]
MySQL 5.0.0, a new version of the popular Open Source/Free Software Database Management System, has been released. It is now available in source and binary form for a number of platforms from our download pages at http://www.mysql.com/downloads/ and mirror sites.
This is the first Alpha development release of the 5.0 tree, adding many new features. As this code is currently labeled "Alpha", we do not recommend that this version be used in production environments yet! It does however pass our test suite on all our build platforms and all old features should be resonable stable.
