[zope] Zope 5.7.3 released with a bugfix

On behalf of Zope developer community I am pleased to announce the release of Zope 5.7.3. This release fixes more rendering issues with some ZMI pages introduced in release 5.7.1. For the full list of changes see the change logs at https://zope.readthedocs.io/en/latest/changes.html#id1 PLEASE NOTE: The next feature release, 5.8, will drop support for Python 3.6. It has been in end-of-life status for a while and supporting it is becoming harder and harder as the infrastructure and software we use for CI is dropping support for it. Installation instructions can be found at https://zope.readthedocs.io/en/latest/INSTALL.html. Jens Vagelpohl
