The Workflow Initiative was announced just over a month ago and since then I have been working on the first phases full-time. Here’s what I’ve touched:
In Drupal 8.1.x the RevisionLogInterface was introduced, but not used. In 8.2.x the Node entity will use it. Also BlockContent entity will use it.
When we make everything revisionable we’ll need all entities to get their base fields from the base class. So from 8.2.x all content entities inherit their base fields.
To help people make sensible decisions Node revisions will now be enabled by default.
We got into a pretty annoying issue when trying to add revision fields to entities which already had data because the revision field couldn’t be set to NOT NULL. Andrei wrote an awesome patch to allow an initial from field to be set. We therefore set the revision id as the entity id.
When we make everything revisionable we’ll need an upgrade path, to test this the Shortcut entity is being upgraded to revisionable by a new service. This has still not been committed, so reviews are welcome.
We’re trying to get Workbench Moderation into core as Content Moderation. Still lots to do to make this happen, but the patch is there with passing tests.
Initial work has also started to get an archive field into all entities. This will allow us to have CRAP (create, read, archive, purge) workflow, create a trash system, and replicate entity deletion through environments.
