Thank you to everyone involved!

Highlights of Plone 6 alpha 6

Major changes since 6.0.0a4:

  • Wait, is there no alpha 5? No. We created an alpha 5 of Products.CMFPlone, which is the main package. Before wrapping up a full Plone release, an important problem was fixed, which required a new release of this package. So now we jump from alpha 4 to alpha 6.
  • The versions.cfg file on dist.plone.org now only contains versions needed for core Plone. We used to pin some often used "ecosystem" packages like plone.app.tiles. Those pins are now in versions-ecosystem.cfg. Several other pins, mostly for tools like zest.releaser, are now in versions-extra.cfg.
  • plone.app.caching: Remove unmaintained Split-View profile.

  • plone.app.content:

    • Remove unused container and item modules.
    • Remove unused IReindexOnModify.
  • plone.app.i18n, plone.i18n, plone.app.multilingual: Use SVG Flags in Language Selector, update name of flags, and prepare to use the Icon Resolver.

  • plone.app.upgrade:

    • Removed old code, aliases and dependencies. We only support upgrading from Plone 5.2 Python 3.
    • Upgrade profiles of core Plone modules to specific versions in the upgrade to alpha 5. This way, when later upgrading a site from 5.2 to 6.1, these initial upgrades are done at the end of the alpha phase, instead of completely at the end. This should avoid some surprises.
    • Add image_scales catalog metadata column. Update all brains to get this info. Since this takes long on large sites, you can disable this with an environment variable: export UPDATE_CATALOG_FOR_IMAGE_SCALES=0. In that case, you are advised to add the image_scales column manually to the catalog later.

  • Products.CMFPlone:

    • Remove Archetypes specific code: isIDAutoGenerated, PloneFolder, DublinCore.py.
    • Moved discussion Key to plone.app.discussion.
    • Added customisable batch_size for redirects controlpanel.
    • Add option to use TinyMCE in inline-mode.
    • Add support for images in default search page.
    • Enable auto include of styles to the TinyMCE formats menu. The file has to be named tinymce-formats.css and known by TinyMCE.
    • Add image_scales to catalog metadata.
    • Sort addons by title
    • Show more information of broken relations
    • Show link to the Volto-migration (@@migrate_to_volto) in the view @@plone-upgrade when the option is available.
    • SVG image as default Plone logo.
  • plone.api: In content.get_view and portal.show_message do not require the request parameter to be specified. If not specified, fallback to the global request.
  • plone.app.contentmenu: Reimplement dropout toolbar submenus and collapsed icons.
  • plone.app.querystring: Add negation-query operators plone.app.querystring.operation.string.isNot and plone.app.querystring.operation.selection.none.
  • plone.app.robotframework: Add keywords for making sure an element is visible before clicking: Wait For Element, Wait For Then Click Element, Wait For Then Click Invisible Element.
  • plone.autoinclude: Raise an exception when a module is not found. When environment variable AUTOINCLUDE_ALLOW_MODULE_NOT_FOUND_ERROR=1 is set, we log an error and continue. To accept ModuleNotFoundError only in specific packages, use a comma-separated list of project names, with or without spaces. See issue 19.

  • plone.base:

    • Add image srcset's configuration including JSON schema definition to imaging-controlpanel.
    • Enable images in search results by default.
    • Add inline mode to tinymce config.
    • Move Products.CMFPlone.utils._createObjectByType to here as utils.unrestricted_construct_instance.
    • Add images interface with IImageScalesAdapter and IImageScalesFieldAdapter.
    • ulocalized_time: accept a string argument to long_format.
      For example: ${a} ${d} hello guys ${b} ${Y}.
      Taken over from experimental.ulocalized_time.

  • plone.scale:

    • Pre scale: store non-random uid to prepare space for a scale. You call pre_scale to pre-register the scale with a unique id without actually doing any scaling with Pillow. When you later call the scale method, the scale is generated. You can still call scale directly without first calling pre_scale.
    • Mark AnnotationStorage with safeWrite fromplone.protect.

  • plone.namedfile:

    • Creating a tag no longer generates the actual scale. The scale is only created when a browser really requests it.
    • Add @@images-test page for Editors. This shows various variants from the image field of the current context. It shows a list of stored scales. It allows purging the stored scales.
    • Add picture method to ImageScaling.
    • Removed marking request for disable CSRF protection
    • Add additional infos in scale storage only if missing.
    • Register adapter for image fields to the new image_scales metadata. Use this in the image_scale view to get images from a list of brains.
  • plone.outputfilters: Add image_srcset output filter, to convert IMG tags into PICTURE tags with multiple source definitions as defined in the imaging control panel.

  • plone.staticresources:

    • Integrate bootstrap and jquery bundles with module federation. They now live in the bundle-plone directory.
    • Update toolbar toggler.
    • Update to latest Mockup with module federation.

    • Add @@migrate_to_volto to prepare existing sites for Volto.

Installation

Installation instructions are being added in this documentation pull request. You can see a preview.

If you cannot follow these docs in progress, the following older notes can be useful.

Some documentation about installation:

If you use Docker, we have some images:

  • plone/plone-backend (5.2 and 6.0)
  • plone/plone-frontend (Volto)
  • plone/plone-haproxy

If you don't do Docker, you will have to do the backend by hand.
The links above should give you information on how to install the prerequisites, like Python, also on Windows.
Here, we will focus on Unix-like systems (Linux, Mac OSX), but Windows should work as well.
The steps are:

  • Install the Plone (Classic) backend with buildout or pip.
  • Create the Plone Site in the browser.
  • Install the Plone frontend (Volto) with node.
