MediaWiki 1.20/wmf3

Deployment of MediaWiki 1.20wmf3 to Wikimedia sites edit

The latest version (labeled "1.20wmf3") of MediaWiki, the software that powers Wikipedia and its sister sites, is currently being deployed to all Wikimedia sites in stages.

We started on Monday, May 14 and will continue until Wednesday, May 23 (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.
