Antares 0.8.0 has been released. This release runs on Mac OS X 10.9+ and, for the first time, Linux. For the time being, Linux users will need to build from source.
Aside from the addition of Linux support, Mac users with Retina displays will notice some graphical improvements (limited for the time being to windowed mode).
Note: there is a known issue in this release relating to dual-GPU MacBooks. For reasons that are still under investigation, performance is very bad when using the dedicated Nvidia GPU. You can use a program such as gfxCardStatus to run on integrated graphics instead.
