On behalf of Zope developer community I am pleased to announce the release of Zope 4.2.1
This is a bugfix release for an unexplained Python 2 compatibility issue that crept into Zope 4.2, despite sufficient unit test coverage that should have discovered the problem.
The release also contains some small fixes and improvements for the WebDAV functionality. For the full list of changes see the change log at https://zope.readthedocs.io/en/4.x/changes.html#id1
Installation instructions can be found at https://zope.readthedocs.io/en/4.x/INSTALL.html
