On behalf of Zope developer community I am pleased to announce the release of Zope 5.0! This release - drops support for Python 2.7 and 3.5 - drops support for `ZServer` - adds support for the newly released Python 3.9 Although this release is a major one, it should be possible to use it without any changes if the following preconditions are met: - Your project runs on the latest Zope 4 release on Python 3.6+ and does not use ZServer. - Neither your tests nor running your Zope instance shows DeprecationWarnings. Additionally this release contains some minor features and bug fixes which have been backported to Zope 4 where possible. As Zope 5 is now released, Zope 4 is put into bugfix mode until 2021-12-31.
