Abstract

Move plone.app.multilingual above Products.CMFPlone in the dependency chain.

Motivation

• There is a circular dependency between plone.app.multilingual and Products.CMFPlone. See Circular dependency between p.a.multilingual and Products.CMFPlone #3859 and p.a.multilingual depends on CMFPlone #3763
• Most Plone sites do not need multilingual support.

Proposal & Implementation

• Remove plone.app.multilingual from the install_requires of Products.CMFPlone.
• Add it to the dependencies of Plone.
• Have a maintenance branch of plone.app.multilingual for Plone 6.0.

Deliverables

• See We need to remove the plone.app.multilingual dependency #3779 for implementation details.
• Add to upgrade guide

Status:

All done, is included since Plone 6.1.0a1.
