Hey Kim,
We haven't released TurboActivate 3.3 yet. It goes into its second round of beta testing by a select group of customers later today, then early next week the final version will be released.
If so, is there some documentation of this?
There will be ample documentation when it's released.
Also, is it available for all price plans?
Yes. All plans get the same latest version of TurboActivate.
