Updated Windows and Linux binaries and packages are available.
One notable fix is for the "Crisp" Alpha Cutout Anti-Aliasing setting introduce in 1.2 which has been causing performance issues when near fogs or smoke for some players while resulting in crashes for Windows users with Intel graphics. In this release the performance issues have been fixed and the setting has been disabled for OpenGL drivers experiencing crashes.
Linux Steam users with Mesa graphics drivers may have noticed textures being replaced with solid colors once the Steam overlay loads. We have added a workaround to no longer promise the graphics drivers that we are good API-respecting citizens if we detect the Steam overlay so that its naughtyness can go unseen again.
