Licence

MediaWiki is free software licensed under version 2 of the GNU General Public License. Because MediaWiki is licensed free of charge, there is no warranty, to the extent permitted by applicable law. Read the full text of the GNU GPL version 2 for details.

System Requirements

MediaWiki requires PHP 5.2.3+ and either MySQL 4+, PostgreSQL, or SQLite. For more information, please read the system requirements.

Note: To get a suitable version of PHP on CentOS 5.6, install the php53 package instead of php.

Other downloads

• MediaWiki 1.18.0 GPG security signature to verify your download with GNU Privacy Guard
• GPG keys
• MediaWiki 1.18.0 changes not including i18n (unified diff)
• MediaWiki 1.18.0 i18n changes (unified diff)

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, your provider might do this. 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.
