Plone 6.0.7 soft released

mauritsvanrees · September 14, 2023, 6:27pm

Plone 6.0.7 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 6.0.7rc1

Last updated: Thursday September 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 versions-extra.cfg and versions-ecosystem.cfg.

Highlights

Major changes since 6.0.6:

Zope: Security fixes in AccessControl and RestrictedPython. See community announcement.
plone.namedfile:
- Add internal modification timestamp with fallback to _p_mtime.
- Use new internal modification timestamp as part of the hash key for scales.
plone.dexterity: Fix a memory leak. For details see issue 3829.
plone.app.widgets: Make this package deprecated. It still works, and is included in Plone 6.0, but Plone 6.1 will not ship with it.
Widget base classes have been moved to plone.app.z3cform.widgets.patterns.
Also see plone.app.widgets.utils for information about moving utility methods to their new location.
plone.app.robotframework: Add support for playwright-based tests via robotframework-browser.
plone.app.z3cform: Introduce new Email-Widget which is used for plone.schema.email.IEmail fields. It uses the input type email.
plone.volto: Add block_types index to zcatalog. By default it is only added for new Plone sites.
To add it to an existing site, run plone.volto.upgrades.add_block_types_index manually.
plone.app.multilingual: Fixes for Indonesian in a multilingual site. Fix set_recursive_language to actually find child objects.
plone.app.querystring: Fix the `currentUser`` operation when the current user's username is different from their user id.
plone.namedfile: Fixed issue with SVG images that contain extensive metadata.
plone.staticresources: update to Mockup 5.1.4:
- pat structure: Fix popover-structure-columns, use 2-column layout. (9fb499e)
- pat structure: Fix sticky position when toolbar is on top.
- pat tinymce: Fix image modal with selected image.
plonetheme.barceloneta: Update Bootstrap to 5.3.1
Products.CMFCore:
- Improve handling of PortalFolder filter input.
- Provide a way to not publish items that are acquired.
plone.restapi:
- Allow passing additional parameters to the delete users endpoint to request not to delete local roles and memberareas.
- When serializing blocks, image_scales is now added to blocks that contain a resolveuid-based url.
- When deserializing blocks, image_scales is removed.
- Add visit_blocks util for finding all nested blocks.
plone.app.locales: Updates to nl translations.

Volto frontend

The default frontend for new Plone 6 sites is Volto. Latest release is 16.24.0. See the changelog.
Note that this is a JavaScript frontend that you need to run in a separate process with NodeJS.

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.

Classic UI

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.

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:

pip==23.2
setuptools==68.0.0
wheel==0.40.0
zc.buildout==3.0.1

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

Note that setuptools 66 or higher 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.
And setuptools 68.1.0 until at least 68.1.2 may give problems with namespace packages, especially when they have multiple levels, like plone.app.*, and are installed in editable mode. And pinning a specific version of setuptools in your virtual environment may not even be enough for this case. See ModuleNotFoundError when running tests on Python 3.11 · Issue #172 · plone/meta · GitHub

Installation

For installation instructions, see the documentation.

Upgrade from 6.0.6 to 6.0.7 raise an error. Looks like a problem between yafowil.plone and plone.app.widgets. I will investigate the Problem.

    ImportError: cannot import name 'get_ajaxselect_options' from 'plone.app.widgets.utils' (unknown location)

petschki · September 15, 2023, 6:00am

Yes, same here with yafowil.plone. It's because plone.app.widgets==5.0 removed plone.app.widgets.utils.get_ajaxselect_options as stated in the deprecation warning in branch 4.x ... I'm upgrading the imports in yafowil.plone now, but one could argue, that it should not break for this minor version update... downgrading plone.app.widgets==4.0.1 works also. I think it would be most convenient if we reimplement the deprecation warning in plone.app.widgets==5.0.1 and simply remove the whole package in Plone==6.1 ...

petschki · September 15, 2023, 6:29am

Update: plone.app.widgets.utils.get_ajaxselect_options got deprecated since version 3.0.0 (see get_ajaxselect_options is no longer used in plone.app.z3cform by jensens · Pull Request #194 · plone/plone.app.widgets · GitHub) so yafowil.plone should really get rid of that.

As this method is stale code in plone.app.widgets since 3.0.0 I'm now against reimplementing it in 5.0.1

yurj · September 15, 2023, 6:43am

No news on the dexterity Provides fix?

mauritsvanrees · September 15, 2023, 7:41am

Yes, this fix is included in the release, with plone.dexterity 3.0.3.
I see the automated changelog generation missed this, and so I missed this when writing release notes. I will update the release notes on dist.plone.org and in my original comment here. Thanks for mentioning it!

For reference, it is this change.

Fix a memory leak as reported in Plone/ZCA memory leak? · Issue #3829 · plone/Products.CMFPlone · GitHub, changing interface declaration type as suggested by @d-maurer in `content.FTIAwareSpecification.__get__` uses the wrong interface declaration type · Issue #186 · plone/plone.dexterity · GitHub [mamico] (#187)

petschki · September 15, 2023, 8:31am

yafowil.plone is fixed here WIP: Bootstrap plone6 by rnixx · Pull Request #29 · bluedynamics/yafowil.plone · GitHub ... hopefully released as 5.0.0a1 soon.

1letter · September 15, 2023, 12:35pm

Thanks, the error is gone!

petschki · September 19, 2023, 11:53am

I tried to upgrade a Plone 5.2.x to 6.0.7rc1 and got the following traceback: problem with plone.base.interfaces.syndication.ISiteSyndicationSettings when upgrading from 5.x to 6 · Issue #315 · plone/plone.app.upgrade · GitHub

I think the upgrade step fix_syndication_settings needs to check if the keys plone.base.interfaces.syndication.ISiteSyndicationSettings do exist.

/cc @1letter any thoughts?

mauritsvanrees · September 19, 2023, 2:11pm

Confirmed, and looks like a blocker. I have fixes here now:

mauritsvanrees · September 20, 2023, 7:38pm

I have released plone.app.upgrade 3.0.8 with the fix, and added it to the versions on dist.plone.org.

Some last-minute changes are being considered, so I am holding off on making the release final for the moment.

mauritsvanrees · September 21, 2023, 4:55pm

Plone 6.0.7 final is out.
