The release is ready to be tagged.
But for the last few hours I have been fighting with updating my developement environment from my current py 3.4 + MingW so I can test the release candidate.
However, so far I was unsuccessful between compiler incompatibilities across MS compiler versions and segfault in the test run.
Here is the sdist of current master, if someone can try it out.
It includes the cython generated C-files and it's what we add on pypi.
The github source archives require cython for building.
