Future-proofing: HTML5 and IPv6: 1.20wmf12, the 12th release to Wikimedia wikis from the 1.20 branch, was deployed to its first wikis on September 17; if things go well, it will be deployed to all wikis by September 26. Its 200 or so changes – 111 to WMF-deployed extensions plus 98 to core MediaWiki code – include support for links with mixed-case protocols (e.g. Http://example.com) and the removal of the "No higher resolution available" message on the file description pages of SVG images.
