MediaWiki 1.20

This is the latest released version of MediaWiki.

Starting in April 2012, the Wikimedia Foundation started deploying MediaWiki to its projects more often (and almost directly from the master branch) through incremental "wmf"-branches within the 1.20 release cycle. The 1.20.0 stable tarball came out 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.


 * 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]
 * New special page Special:MostInterwikis.
 * New magic word   which gives the current page ID.
 * The info action has been reimplemented.
 * Minimum PHP version is now 5.3.2.

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

Other:
 * No new extensions bundles have been done for this release.
