None really. Lots of packages have gotten a final release, losing their alpha, beta or release candidate markers.
We are in a bugfix-only mode. An upgrade from rc1 to rc2 should be painless and is recommended for everyone.
Volto frontend
The default frontend for Plone 6 is Volto. Latest release is 16.3.0. See the changelog.
Note that this is a JavaScript frontend that you need to run in a separate process with NodeJS.
The ClassicUI 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.
Installation
For installation instructions, see the documentation.
This documentation is under development, but this should get you up and running. No worries.
We expect to switch https://docs.plone.org to show the Plone 6 documentation sometime this week.
Final release date: December 12, 2022
Unless blocking issues are found that require more work, we expect to release Plone 6.0.0 final one week from now:
December 12, 2022.
If you find any issues, blocking or not, please report them in the main issue tracker.
According to the byline code this works as follows:
Show the publication date only if "Show the publication date" setting is enabled.
Regardless that setting the modification date is shown either:
When there is no publication date yet (ex: the item is private)
The modification date is later than the publication date
Weird? Could be. Perhaps we can improve that in some other way. But I see it working.
Regarding the REST API, the REST API doesn't handle those settings like "Show the publication date", "Hide the author", etc. The REST API just exposes all the information.
The setting is called display_publication_date_in_byline so I would assume that the date is only shown when I published the document and I activated this setting ...
The logic for the byline viewlet has changed between 5.2 and 6.0, and the current code is not completely logical, to me anyway. I have created an issue: Inconsistency in document byline · Issue #330 · plone/plone.app.layout · GitHub
But no blocker, let's see if we can fix this in 6.0.1. For now you can experiment with different combinations of the two settings I mention there, and see which combination works best for you.
