I’m pleased to announce a fix for improved Cython support per Setuptools #288 (https://bitbucket.org/pypa/setuptools/issue/288). I’ve published a beta release 18.0b1 in the Setuptools project downloads (https://bitbucket.org/pypa/setuptools/downloads/setuptools-18.0b1.zip) for pre-release testing. Release notes are here (https://bitbucket.org/pypa/setuptools/src/4249669040239bff20196b17ccd4d73870d37343/CHANGES.txt#cl-10).

Please, if you use any projects with Cython modules, give this install a trial run and report any issues in the Setuptools bug tracker. I hope to release 18.0 in the next few weeks if there aren’t any emergent blockers.

Thanks!

Jason
