Wikipedia:HTML5

The development of HTML5 is now so far advanced that it was incorporated into the MediaWiki software and has been the default on Wikimedia wikis since September 2012.

This project serves to help editors organize the adaptation of articles and other Wikipedia pages to HTML5. The fifty or so prepared searches reveal the obsolete tags. The edits range from simple to complex, and the numbers from a few fixes anyone can enjoy updating manually, up to many thousands for a run with a Wikipedia:AutoWikiBrowser bot script.
