MySQL 5.0.12-beta released.

A new version of MySQL Community Edition 5.0.12-beta Open Source database management system has been released. This version now includes support for Stored Procedures, Triggers, Views and many other features. It is now available in source and binary form for a number of platforms from our download pages at http://dev.mysql.com/downloads/ and mirror sites.

Note that not all mirror sites may be up-to-date at this point. If you cannot find this version on a particular mirror, please try again later or choose another download site.

This is the eighth Beta release in the 5.0 series. All attention will continue to be focused on fixing bugs and stabilizing 5.0 for later production release.

NOTE: This Beta release, as any other pre-production release, should not be installed on ``production'' level systems or systems with critical data. It is good practice to back up your data before installing any new version of software. Although MySQL has done its best to ensure a high level of quality, protect your data by making a backup as you would for any software beta release.

Please refer to the bug database at http://bugs.mysql.com/ for more details about the individual open and resolved bugs in this version.

Changes in release 5.0.12:

Functionality added or changed:

  • Recursive triggers are detected and disallowed.
  • Natural joins and joins with USING, including outer join variants, now are processed according to the SQL:2003 standard.
  • SHOW OPEN TABLES now supports FROM and LIKE clauses.
  • SHOW TABLE STATUS FROM INFORMATION_SCHEMA now sorts output by table name the same as it does for other databases.
  • Added the SLEEP() function, which pauses for the number of seconds given by its argument.
  • The stability of cursors when used with InnoDB tables was greatly improved.
  • It is no longer possible to issue FLUSH commands from within stored functions or triggers.
  • An optimizer estimate of zero rows for a non-empty InnoDB table used in a left or right join could cause incomplete rollback for the table.

And many more...
