Changelog for Patch 2.0.2.87.5828 (added 16 January 2018):

Multiplayer:
- Ranked games points calculation has been changed:
--- First player to leave, before the end of peace time receives a penalty to his score and defeat, even if his team has won the match.
--- Any player who'd leave after the first one, won't receive any penalties.
--- Leaving the game after peace time is over won't net a penalty. Points would be granted according to team's performance during the match.
--- Player, who has got an ally leaver before the peace time was over, won't receive any defeat penalty, but will get victory points, in case he'd win.
- Fixed errors, which prevented player from receiving points after the match is over.
- Changed the mechanism of ranking in multiplayer. It's easier to get promotion to higher ranks now and players are distributed more evenly on ranking scale.
- Matchmaking algorithm for quick games has been improved.
- Fixed a rare error, causing nonmirror matches. Earlier, it was possible to have a Poland+Poland vs Turkey+Turkey matchup, instead of even nation distribution between teams.
- Multiplayer games stability has been improved. Fixed some errors causing the game to 'hang up'.
