In reply to Devin.

That's a useful figure to know, thanks for checking! I wonder if you looked again in 6 months, if we'd have gone up by any significant amount. TGMPA hasn't really changed since March 2014, so it's been dormant. I'd love to see the 2.50 release reach 7%, and the 3.0.0 release reach 10% of WPORG themes.
Then there's WPORG plugins, GitHub-only themes and plugins, Theme Forest, Code Canyon etc. :-)
