[zope-annce] Zope 5.7 released

On behalf of Zope developer community I am pleased to announce the release of Zope 5.7. This feature release adds full support for Python 3.11 and a ZPublisher encoder for inputting JSON data. It also cleans up several smaller issues and will be the base for the first Plone 6 release candidate. For the full list of changes see the change log at https://zope.readthedocs.io/en/latest/changes.html#id1. Installation instructions can be found at https://zope.readthedocs.io/en/latest/INSTALL.html. Jens Vagelpohl
