• Note: the last stable release doesn't contain all bug fixes to the stable branch: you can try its last snapshot, but almost surely not all the fixes for the known bugs in the stable release have yet been included in such snapshot.

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 5.3.2+ and either MySQL 5.0.2+, PostgreSQL, or SQLite. For more information, please read the system requirements and compatibility.

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

Alternatives to manual installation

Some users may prefer to skip manual installation by using a pre-integrated MediaWiki software appliance or hosting services with 1-click installation and wiki farms.

Other downloads

• MediaWiki 1.21.0 GPG security signature to verify your download with GNU Privacy Guard
• GPG keys
• MediaWiki 1.21.0 changes not including i18n (unified diff)

Download through Git/command line

For downloading MediaWiki from Git or from the command line, see Download from Git.

Notes

• PHP 5 support has been required since MediaWiki 1.7 – if you are using PHP 4, you should upgrade now! PHP 4 is no longer supported by the PHP group and has many bugs and vulnerabilities. Many shared hosting providers offer both PHP 4 and PHP 5, running simultaneously. If you cannot upgrade, you can use MediaWiki 1.6.12 (download). Note that this version is no longer supported.
• MySQL 5 support is required since MediaWiki 1.19 – if you are using an older version of MySQL and cannot upgrade, you can use MediaWiki 1.18.6 (download). Note that this version is no longer supported.

Legacy releases

If your MediaWiki installation is heavily modified, it may be difficult to incorporate the latest official changes/updates to MediaWiki. To support such users, we maintain old branches of our code for up to a year for the legacy release (1.20.6) and up to three years for the legacy long term support release (1.19.7).

• Download legacy release MediaWiki (1.20.6)
• Download legacy lts release MediaWiki (1.19.7)

Development releases

If you want to run on the latest development (i.e. alpha) version, you either download Nightlies, or download from Git.

From Git you can either download the complete repository (about 375 MB)

git clone https://gerrit.wikimedia.org/r/p/mediawiki/core.git

or the latest revision from the repository only (this is often called a shallow clone: less time and smaller downloads).

git clone --depth 1 https://gerrit.wikimedia.org/r/p/mediawiki/core.git

You can also view the latest source code in your browser.

Old releases

You can find tar balls (*.tar.gz) of all versions of MediaWiki back to February 2007 in the MediaWiki download archives

To browse, including even older versions, see the tags, of the Git repository.
