• 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.

License

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 7.0.0+ and either MySQL 5.5.8+, MariaDB, or one of the other three possible stores. For more information, please read the pages on system requirements and compatibility.

Other downloads

• GPG security signatures to verify your download with GNU Privacy Guard:
  • MediaWiki 1.31.1 - stable LTS
  • MediaWiki 1.30.1 - legacy
  • MediaWiki 1.27.5 - legacy LTS
• GPG keys
• MediaWiki 1.31.1 changes not including i18n (unified diff)

Download from Git instead

Active MediaWiki developers should instead download from Git to get the latest version of the MediaWiki software. The git repository has earlier versions of the software, so it is possible to switch to ("check out") a particular release.

Notes

Support for PHP's register_globals directive has been removed since MediaWiki 1.24 . If you have PHP 5.4 or later installed on your server, you do not need to worry about this. If you have PHP 5.3 or earlier, make sure that this directive has been turned off. If you cannot turn register_globals off on your system, you can use MediaWiki 1.23.9 (download).

MySQL/MariaDB 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.

Alternatives to manual installation

Some users may prefer to skip manual installation by using a pre-integrated MediaWiki software appliance or hosting services; repositories of some distros also increasingly offer packages for MediaWiki, with different degrees of frequency and extensions coverage (e.g. Debian, Ubuntu, Fedora, Gentoo).

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 and up to three years for the legacy long term support release.

Development releases

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

From Git you can either download the complete repository (about 528 MiB)

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

or the latest revision only (about 85 MiB; this is often called a shallow clone: less time and smaller downloads).

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

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

Old releases

You can find tarballs (with extension *.tar.gz) of all versions of MediaWiki back to March 2005 (the earliest being MediaWiki 1.3.11) in the MediaWiki download archives.

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