1.50 is a version with not that many "os-related" updates, but it does bring something new: BoredOS! Since BrewOS was already being used for a custom operating system for smart coffee machines, i decided to copy the naming of my github username: BoreddevNL and turned that into, well BoredOS. Anyways this update brings some extra stability and graphical bug fixes, that's about it. Oh yeah also a mouse sensitivity slider in the control panel. Enjoy!
