Plone 6.0.9 has been soft released today. 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.
- Released: Thursday December 14, 2023
- Check the release schedule.
- Read the upgrade guide, explaining the biggest changes compared to 5.2.
- Canonical place for these release notes and the full packages changelog.
If you want to jump straight in, here are two important links:
- With pip you can use the constraints file at https://dist.plone.org/release/6.0-dev/constraints.txt
- With Buildout you can use the versions file at https://dist.plone.org/release/6.0-dev/versions.cfg, plus optionally
Major changes since 6.0.8:
- Plone 6.0.9 is the first release to officially support Python 3.12!
Zope: Officially support Python 3.12.
- Added preview_image and preview_image_link to the list of smart fields for resolveuid and link integrity.
- Version 6.0.0 supports Python 3.12.
- It also switches "to using
async/awaitdirectly instead of
- That last change sounds like it could potentially have unforeseen side effects, so it would be good to get this more field tested.
(I may be too cautious here.)
- So for Python 3.11 and lower we pin 5.4.1, and on Python 3.12 we pin 6.0.0.
You are encouraged to try out the newer version on all Python versions, and report any problems.
We will likely pin the new version for all Python versions in the next Ploen bugfix release.

Also, existing Plone sites need some or more extensive changes to be upgraded before they can use the Volto Frontend. Please read the guide on migrating from Plone Classic UI to Volto.
Note that Volto 17 is also available, and you can use it on Plone 6.0, but we will keep recommending Volto 16 by default.
The HTML based and server side rendered UI that was present in Plone 5.2 and earlier major Plone releases is still available and has also been updated and improved upon in Plone 6. Our documentation now refers to this frontend as 'Classic UI'. Support for Classic UI is especially relevant for existing Plone sites which for whatever reason or requirements are not yet ready to be upgraded to the Volto frontend.
This release supports Python 3.8, 3.9, 3.10, 3.11, and 3.12.
Plone 6.0.9 is the first release that officially supports Python 3.12. This is made possible by recent changes in
Note that Plone 6.0 is tested on Python 3.8 and 3.11 on every change to core packages. For the other Python versions we run the tests once a week.
In Plone core we use these versions to install Plone:
In general you are free to use whatever versions work for you, but these worked for us.
