The ChessBase version is indeed out today. Normally our own release from Komodochess.com would have been out before the ChessBase version, but as it happens we found significant enhancements right after our ChessBase deadline and wanted to include them in our own release since without them the gain from Komodo 10.4 was too small to justify for us (not a problem for ChessBase since they can compare to Komodo 10). Due to family issues Mark couldn't get the improved version ready before the CB release.
So, we plan to release the improved version next week. If ChessBase offers it as a free upgrade we'll follow their lead on the name, if not we'll probably just put it out as Komodo 11.01 or even Komodo 11.1. We recommend that the testing groups NOT rate the ChessBase version but wait for our own release, since the improvements are probably greater than the improvements between Komodo 10.4 and Komodo 11 Chessbase. It's annoying that we found these gains after the CB deadline rather than before, but no one can predict when discoveries will be made. Better late than never.
