As mentioned before, MAC and Linux version only on major updates. (Previous was 0.15, and next is 0.20 that is soon, this was an unexpected hotfix)
As proven in this minor version, that has taken 3-4 weeks for people to find important bugs to hotfix in Windows, with more than 5000 players, I can only take all the development time to make the compatibility with Linux and Mac when a version is very stable... and the only way I have enough testers to test that stability in a short period of time before start working on the next major update is only when I release a major update, as I run down after those MAC testers....there is a total of less than 2-3 people that appear some time (by sometime I mean every 3-4 months top) that even test and tell me if the Mac and Linux version works so... that's a problem.
I need to be able to know if those versions work before I can get back to work on next update.
In four months I think only one MAC user and one Linux user have confirmed that previous major update even works, so....
So... that. xD
