Just a couple weeks ago we reported that Google will soon support Schema version 3.1 with their structured data testing tool. Well, it seems as of yesterday, Google now supports it.
Brad Brewer posted on Google+ with a screen shot of it working on a site that uses schema v3.1.
He said "Webmasters can now validate schema.org 3.1 markup using the Google Structured Data Testing Tool."
Here is the Google tool and here is an example of a site using Schema 3.1 that works in the tool.
So go at it schema nuts!
