Core One kit issues fixed?

REALLY excited for my 3 different CoreOne Kits to arrive this week and was reading some older posts about issues that needed resolving.

Curious if these have been fixed on the Prusa side or instructions updated at least since the printer has been out so long now.

E.g. apparently the motors weren't grounded so static was building up and shorting/restarting the board, there were certain screws that needed thread lock because the metal to metal was vibrating itself loose, gantry square and y axis conflict issues, etc.

Couldn't find any update threads about this so I figured I'd ask before I'm too far along and find my own mistakes!

Thanks!
