Buying ToonBoom Question

I am currently trying the trail version of Studio. Deciding if it’s the one I want to buy, or Animate. Just a couple of questions. What is the latest version of Studio? Is it 6? Are there any YouTube Tuts on the latest version for nubes? Are there any PDF’s or Text downloads that are available for the latest version? How about community support that really want to help people getting started with Toon Boom software?
