Arasan 12.2 released

[beachknight]

Thank you. For rating calculation, I might combine the games of 12.1
and 12.2 since they have not played sufficient games.

Not sure that makes sense, since what I am saying is, I don't think they are the same strength.

Oooops. I misunderstood.
I wrongly read that 12.2 is about equal 12.1 and stronger than 11.7.
You meant that 12.2 is stronger than both 11.7 and 12.1.
