Zope 5.14.2 released
by Jens Vagelpohl 07 Mar '26

07 Mar '26

On behalf of Zope developer community I am pleased to announce the release of Zope 5.14.2. This release fixes namespace package-related issues under certain conditions by requiring the latest zc.buildout release 4.2.0. Developers, administrators and package maintainers please note: The Zope 5 release series is not compatible with PEP 420-style namespace packages for at least the Products namespace, and installing it requires zc.buildout<5, which is pre-PEP 420 as well. That means the zc namespace packages must also be pre-PEP 420. Make sure to prepare your sandboxes with these versions: $ bin/pip install -U 'setuptools>=78.1.1,<80' 'zc.buildout>=4.2.0,<5' Links to more information: - full change log: https://zope.readthedocs.io/en/5.x/changes.html - installation instructions: https://zope.readthedocs.io/en/5.x/INSTALL.html - documentation: https://zope.readthedocs.io/ - source code: https://github.com/zopefoundation/Zope Jens Vagelpohl

Zope 6.0 released
by Jens Vagelpohl 04 Mar '26

04 Mar '26

On behalf of Zope developer community I am pleased to announce the release of Zope 6.0. It does not bring added features compared to the 5.x release series, but switches namespace package declarations from the old "pkg_resources"-style to PEP 420 implicit namespaces. The switchover may be a breaking change under some limited circumstances, thus the new major release version. See https://zope.readthedocs.io/en/latest/migrations/zope6.html for migration information. If you want to stay on Zope 5 check out the recent release of version 5.14.1 at https://pypi.org/project/Zope/5.14.1/.

On behalf of Zope developer community I am pleased to announce the release of Zope 5.14.1. This comes hot on the heels of Zope 5.14 and fixes an issue with generating the Zope console scripts.
