I've just released version 0.2.5 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: * Changed regular expressions to be compatible with 3.6 as regards escape sequences. * Closed some resource leaks related to XML-RPC proxies. * Changed wheel processing to look for metadata in metadata.json as well as pydist.json. * Updated requirement and marker parsing to be compatible with PEP 508. * Made downloadability a factor in scoring URLs for preferences. * Removed Python 2.6 from the support list. 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!
