Notes

• PHP 5 support has been required since MediaWiki 1.7 – if you are using PHP 4, you should upgrade now! It's no longer supported by the PHP group, and has lots of bugs. Many shared hosting providers offer both PHP 4 and PHP 5, running simultaneously. If you cannot upgrade, you should use MediaWiki 1.6.12 (download). Note that this version is no longer supported.
• MySQL 4 support has been required since MediaWiki 1.6 – if you are using an older version of MySQL and cannot upgrade, you should use MediaWiki 1.5.8 (download). Note that this version is no longer supported, but should still support PHP 4 as well.
• MySQL 5 support is required since MediaWiki 1.19 – if you are using an older version of MySQL and cannot upgrade, you should use MediaWiki 1.18.3 (download).
