Adobe AIR for TV in 2014?

Hello, I've been using Adobe AIR in the latest years to build mobile apps, but I've never used it for TV apps. The info I've seen about AIR for TV is mostly talking about very old versions of AIR (2.5). Is that still supported? What TVs are compatible with Adobe AIR? Is there any testing environment I can install in a PC to test TV apps?

Thank you!
