Server-side adjustment has been applied to the European game-server earlier today (July 5th). The adjustment has been connected with team killing and team damaging. One will get team killer statuses quicker now (the amount of credits subtracted as penalty has not been changed, but one can get banned for TK more easily). Penalty rates for "splash" damage remain the same.
The update was server-side. Your game client doesn't require any updating.
