Plone 6.0.3 soft released

Plone 6.0.3 has been soft-released. Please give it a try and let me know if there are any critical issues.
For those who haven't run across soft-releases before, this is the last step before the final release. Because things haven't been finalized yet, some packages may change between now and the release. It is not recommended to use soft-releases in production.

Release notes for Plone 6.0.3rc1

For technical wizards who want to jump straight in, here are two important links:


Major changes since 6.0.2:

  • plone.base: Move to .navigationroot.get_navigation_root.
    Move to .navigationroot.get_navigation_root_object.
    Both are essential basic functions in Plone and not layout related at all.
  • Zope: Replace cgi.FieldStorage by multipart avoiding the cgi module deprecated by Python 3.11.
    Mark binary converters with a true binary attribute.
    Fix encoding handling and :bytes converter.
    This affects the way Zope handles request data, but in core Plone no changes were needed, except in a few tests.
  • plone.restapi:
    • Fix missing Decimal field deserializer.
    • Fix translation of the error message for a password that is too short while adding a user.
    • Provide slateTable block serializer/deserializer to properly convert URLs to uids.
  • plone.staticresources: Upgrade Mockup to 5.0.6. This introduces the pat-checklist pattern.
  • Products.CMFPlone: Use the new pat-checklist for groupuser management, and fix userlisting batch/showAll in group membership template.
  • Update translations for pt_BR.
  • Various packages: drop support for older Python, Zope or Plone versions, declare dependencies better, fix deprecation warnings, cleanup code.

Volto frontend

The default frontend for Plone 6 is Volto. Latest release is 16.18.0. See the changelog.
Note that this is a JavaScript frontend that you need to run in a separate process with NodeJS.
The Classic UI is still available when you only run the Python process.

Python compatibility

This release supports Python 3.8, 3.9, 3.10, and 3.11.

pip, buildout, setuptools

In Plone core we use these versions to install Plone:


In general you are free to use whatever versions work for you, especially newer ones, but these worked for us.

Note that setuptools 66 is more strict with what versions it can recognize. If you run pip or buildout and it suddenly cannot find a package with a non-standard version, then this may be the cause. This is why we stayed at version 65 for this release.
This already needed a fix in Products.GenericSetup in the code that ordered upgrade steps.


For installation instructions, see the documentation.


If you find any issues, please report them in the main issue tracker.


In case someone is using dexterity.membrane out there, there's a fix for AuthEncoding==5.0 here which will be merged and released soon.
