Feel free to try MSS on a system we had not tested, and let report us by creating an issue.

Python GNU/Linux MacOS X Windows
3.7-dev True True True
3.6 True True True
3.5 True True True
3.4 True True True
3.3 True True True
2.7 True True True


  • Support ReactOS and other systems on OS stability or available hardware.
  • Any idea?


Tested succesfully on Pypy 5.1.0 on Windows, but speed is terrible.


  • Support for Python 2.6 was dropped on 2016-10-08: too old and introduced optimizations broke it.
  • Support for Python 3.0, 3.1, and 3.2 was dropped on 2016-10-08: there is no more tests facilities.

By the way, if you find the force, give it a try and tell us if you managed to make one of these versions working (a patch should be quite easy).
