 This is a variant of `InlinePanel` that improves the editing experience when the main feature of the child panel is a chooser for a `ForeignKey` relation (usually to an image, document, snippet or another page). Rather than the "Add" button inserting a new form to be filled in individually, it immediately opens up the chooser interface for that related object, in a mode that allows multiple items to be selected. The user is then returned to the main edit form with the appropriate number of child panels added and pre-filled.

 ## Enabling workflows for snippets
 
-```{versionadded} 4.2
-The `WorkflowMixin` class was introduced.
-```
-
 If a snippet model inherits from {class}`~wagtail.models.WorkflowMixin`, Wagtail will automatically add the ability to assign a workflow to the model. With a workflow assigned to the snippet model, a "Submit for moderation" and other workflow action menu items will be shown in the editor. The status side panel will also show the information of the current workflow.
 
 Since the `WorkflowMixin` utilises revisions and publishing mechanisms in Wagtail, inheriting from this mixin also requires inheriting from `RevisionMixin` and `DraftStateMixin`. In addition, it is also recommended to enable locking by inheriting from `LockableMixin`, so that the snippet instance can be locked and only editable by reviewers when it is in a workflow. See the above sections for more details.
