You're fine as it is. Do not upgrade.
The latest version adds support for Chromecast but Apple TV users get no additional benefit. And even though you can still use 3.0 unlimited if you're 2.0 user, you still need to get rid of upgrade window that will appear every time you're launching the app, which is very annoying.
