On behalf of Zope developer community I am pleased to announce the release of the first alpha release of the Zope 5 series: 5.0a1 Zope 5 drops support for * Python 2.7, it supports Python 3.5 up to 3.8 * ZServer, it is now WSGI only To migrate to Zope 5: first migrate to the lastest Zope 4 release. If your code runs on the WSGI stack without showing deprecations warnings it should also be able to run on Zope 5, too, without changes. All other changes (besides these non-backwards compatible ones) have been back ported to Zope 4.x. (We will keep doing so until the final Zope 5 release.) For details of the changes see https://zope.readthedocs.io/en/latest/changes.html#a1-2020-02-28 To install the new version see https://zope.readthedocs.io/en/latest/INSTALL.html -- Mit freundlichen Grüßen Michael Howitz
