After a bit of probing, it appears the somewhat critical patch may be due to a ball trajectory cheat which was starting to make the rounds within the game. If players are able to see precisely where the ball is heading then this would obviously give them a huge advantage over non-cheating players.

Rocket League has been a huge success story for Psyonix, a company previously only really known for their minor contributions to franchises like Mass Effect, XCOM, Gears of War and Unreal Tournament. Rocket League itself has earnt critical acclaim and has a huge player base, yet at its core is a fairly simplistic pick-up-and-play title, albeit hard to master.

The surprise Rocket League update went live across all three platforms earlier today, and is approximately 1.7 GB on consoles. We’ll update this post when we get confirmation from Psyonix regarding any other information about the patch.

Edit: We just got official patch notes sent through, and there is nothing mentioning the ball trajectory exploit, but there are a few bug fixes:
