TL;DR: UPDATE NOW

Hey, drivers! Long time, no see!

A few hours ago, Unity (the game engine Jeepney Simulator 2 uses) officials gave a notice regarding a vulnerability within Unity versions 2017.1 and higher. This vulnerability makes it so attackers can harm your pc. The Jeepney Simulator 2 v1.1.2 update uses the patch that Unity has provided, which fixes this vulnerability. Please update to this version as soon as possible in order to avoid any potential risks. Thank you!
