Nope this is not the final version. This is an RC (Release Candidate), which means its in the final stages of beta. There could be a couple of more RC's before the final version is finally released. Sadly still not here

Whyyyyyyyyyyyy. I hate this tethered crappp....ok answer me this how many RC versions come out before the final release??? I have a funny feeling tha the final release will be any day now!!!!! hopefully

There is not set number of RC's, however they don't typically exceed 7 (but they can).
