The MediaWiki language extension bundle (MLEB) is a curated set of MediaWiki extensions offering multilingual features. It attempts to provide an easy way to bring comprehensive language support to a MediaWiki.
The current version of MLEB contains the following extensions:[1]
MLEB is released semi-annually after the new MediaWiki release and will only support the latest MediaWiki version. The bundle is tested against recent MediaWiki release versions, so you can avoid most of the temporary breaks that would happen if you were using the latest development versions of each extension.
MotivationThe Universal Language Selector is a must have, because it provides an essential functionality for any user regardless of the number of languages they speak: language selection, font support for displaying scripts badly supported by common operating systems, and input methods for typing languages that don't use the Latin alphabet. It includes freely-licensed fonts, which cover most of the major languages of America, Europe, Middle East, India and South East Asia.
Maintaining multilingual content in a wiki is a mess without the Translate extension, which is used by Wikimedia Foundation, KDE, translatewiki.net and other sites.
The CleanChanges extension keeps your recent changes page uncluttered from translation activity and other clutter.
Don't miss the chance to practice your rusty language skills: Use the Babel extension to mark the languages you speak and find other speakers of the same language in your wiki. And, finally, the CLDR extension is a database of language and country translations.

Add/update your LocalSettings.phpNear the end of LocalSettings.php, you have to place this configuration:
wfLoadExtension( 'Babel' ); wfLoadExtension( 'cldr' ); wfLoadExtension( 'CleanChanges' ); $wgCCTrailerFilter = true; $wgCCUserFilter = false; $wgDefaultUserOptions['usenewrc'] = 1; wfLoadExtension( 'Translate' ); $wgGroupPermissions['user']['translate'] = true; $wgGroupPermissions['user']['translate-messagereview'] = true; $wgGroupPermissions['user']['translate-groupreview'] = true; $wgGroupPermissions['user']['translate-import'] = true; $wgGroupPermissions['sysop']['pagetranslation'] = true; $wgGroupPermissions['sysop']['translate-manage'] = true; $wgTranslateDocumentationLanguageCode = 'qqq'; $wgExtraLanguageNames['qqq'] = 'Message documentation'; # No linguistic content.

php maintenance/run.php updateWeb browser
Go to example.com/mediawiki/mw-config/ (see Manual:Upgrading#Web browser) by using your domain and path and rerun install.
Configuring and using extensionsSee the respective extension documentation pages.
MLEB does not use version-specific branches of extensions. It's a snapshot from master which is verified to be working with the latest MediaWiki releases at the time MLEB is released.
MLEB releases are created with a tool called Melange. If you are interested in that code (e.g. you want to change its code), see the Melange repository in Git. We may drop support for EOL versions of PHP, but will have at least one compatible version for each MediaWiki version we support.
