Sorry for interfering, but this tournament wasn't originally planned for the new version. And this tournament features the top players who play what they know and what they're good at, just like any other top players. The guitarist of Metallica wouldn't try out a "Ural" guitar before a concert, and a top athlete wouldn't wear equipment from an unproven brand. The same applies here: what prevents launching a test tournament on version 1.5, and holding this one on a well-tested version?
