Well, I reluctantly registered for the tournament just for the blitz mode, despite the hotkeys. But then it turned out that I still need to figure things out myself in the hotkeys, because the developers didn't bother to create a manual. I could just give up and withdraw after the first round...
There is a clear general manual and detailed descriptions of the new features in each version.
A regular and extended list of changes:

P.S. It takes a maximum of 30 seconds to find it yourself (more than the time it took to write the post about "not bothering to create a manual").
