Don't be so bothered by official stuff, it's just a simple changelog anyway. And Graviteam is not a lawyer-loving corporate schmucks like some big companies!
You are wrong about my English. It's half- Google-babble, and a third- boring dictionary lookup. I'm trying to improve, but so slowly. I wish learning foreign languages was a lot easier (yes, lazy ruskie).
Quizing? Yeah, Russians, Belorussians, Ukrainians (don't know about other ex-USSR-ians) like booze and talks about ultimate questions of life, the universe, and everything when drunk.
So, they got a mental boost to understand you!
I don't know about 5.81. Currently, only Gravi-team knows what works, and what's not. I'm sure you saw F5E screen at sukhoi.ru, nothing new so far. But I'm pretty sure they could even include your Sally APC, if you ask Andrey (and wish to do that, of course).
