I suspect that it is not yet available
Quote: "Half way through March we realised we had added so many commands that a March release would have risked stability, so we have given ourselves April to refine the commands, bolster the documentation and test the new command set."
So they are adding a lot of commands, and of course this require a lot of additional time for testing and regression.
Anyway, as soon as the 107 shall be released, I suppose that it shall be available for download under "Your products" in your TGC account, if you have bought the community edition (as I did).
I agree that it is an already very cool product with version 1065, but now with the new commands, the product MUST become a top seller. Lee, Paul and others are really smart guys, and their products deserve a lot of success.
