What is the most recent edition of Chessmaster?


Chessmaster Grandmaster Edition (aka Chessmaster 11).
I don't think it's much better than CM 10th, except it has Waitzkin's "The Art of Learning" tutorial (which I haven't looked at).

The only potential problem with all of the Chessmaster programs is that they're getting really dated, and I don't know how compatible they'll be with Windows 10.
