I've recently released version 0.3.2 of distlib on PyPI [1]. For newcomers, distlib is a library of packaging functionality which is intended to be usable as the basis for third-party packaging tools. The main changes in this release are as follows: * Fixed #139: improved handling of errors related to the test PyPI server. * Fixed #140: allowed "Obsoletes" in more scenarios, to better handle faulty   metadata already on PyPI. * Fixed #141: removed unused regular expression. * Fixed #143: removed normcase() to avoid some problems on Windows. * Fixed #146: added entry for SourcelessFileLoader to the finder registry. * Fixed #147: permission bits are now preserved on POSIX when installing from a wheel. * Made the generation of scripts more configurable. * Added support for manylinux wheel tags. A more detailed change log is available at [2]. Please try it out, and if you find any problems or have any suggestions for improvements, please give some feedback using the issue tracker!
