MediaWiki 1.20

MediaWiki 1.20 is the latest release of MediaWiki. This is a summary of the major changes of interest to users. You can consult the RELEASE-NOTES file for the full list of changes. It was deployed to Wikimedia wikis through incremental "wmf"-branches starting April 2012. Final version was released on November 7th 2012, see Download.

What's new?
MediaWiki 1.20 includes all changes released in the smaller bi-weekly "1.20wmfX" updates for Wikimedia sites. An overview of their changes is available only for 1.20wmf1.

Diff
New diff view, greatly improved in clarity especially when viewing at small changes to pages (including whitespace changes) and colour-blind users. This fixes at last a major deficiency in MediaWiki's accessibility, already noted by Sunir Shah in 2001.[//meta.wikimedia.org/w/index.php?title=User:Magnus_Manske&diff=377&oldid=180]
 * With the latest version, spotting changes is much easier. It's speeded up workflow considerably: the kdenlive manual has many pages where small updates have been made, it would have taken me ages with the old diffs. — Anne Wilson

New features

 * New special page Special:MostInterwikis.
 * New magic word   which gives the current page ID.
 * The info action has been reimplemented.

Internationalization

 * New languages supported: Emilian (egl), Tornedalen Finnish (fit), Mizo (lus), Santali (sat), Turoyo (tru)
 * New Cyrillic-Latin language converter for Uzbek (uz)

Heads-up for MediaWiki administrators

 * Minimum PHP version is now 5.3.2.
