"Dear Leaguers,
Today we are applying security messure to try to get rid of the hacks in S4 League!
Like before we can't go into specifics of exactly what's in this patch for obvious reasons, but this is what was implemented:
Improved In-game system checking. We will continue to fight against the hackers and hopefully, together with GameOn we will have a fix for the rest soon!"
