MediaWiki 1.20/wmf12

Deployment of MediaWiki 1.20wmf12 to Wikimedia sites
The latest version (labeled "1.20wmf12 ") of MediaWiki, the software that powers Wikipedia and its sister sites, will soon be deployed to all Wikimedia sites in stages.

Deployment will start on Monday, September 17 and continue until Wednesday, September 26 (see the roadmap).

We will continue to deploy the latest software every two weeks. This is intended to minimize disruption and possible issues, and make it easier to identify the cause of problems, since the possibly problematic code will be much more recent.
