I'm pleased to announce the release of six 1.4.0. This release sees
some nice improvements, most significantly a much-requested
compatibility layer for the Py3 urllib package. I'd like to thank Marc
Abramowitz for contributing that as well as Jason R. Coombs for
several other helpful pull requests. See the appended changelog for a
complete picture of the changes in this release.
