Upgrade considerations - changes affecting Wagtail customisations

ModelViewSet automatically registers the model to the reference index

Models that are registered with a ModelViewSet now have reference index tracking enabled by default. This means that you no longer need to call ReferenceIndex.register_model() in your app's ready() method for such models. If this is undesired, you can disable it by setting {attr}~wagtail.admin.viewsets.model.ModelViewSet.add_to_reference_index to False on the ModelViewSet subclass. For more details, see [](managing_the_reference_index).

Groups IndexView.results_template_name renamed from results.html to index_results.html

The IndexView's results_template_name attribute in the GroupViewSet has been renamed from wagtailusers/groups/results.html to wagtailusers/groups/index_results.html for consistency with the other viewsets. If you have customised or extended the template, e.g. for [](customising_group_views), you will need to rename it to match the new name.

Breadcrumbs class name has changed

If using custom styling for the breadcrumbs, this class has changed from singular to plural for a more intuitive class.

Old	New
'w-breadcrumb'	'w-breadcrumbs'

Breadcrumbs now use different data attributes and events

The undocumented JavaScript implementation for the header breadcrumbs component has been migrated to a Stimulus controller and now uses different data attributes.

This may impact custom header implementations that relied on the previous approach, custom breadcrumbs that did not use breadcrumbs and require the expand/collapse behaviour may be impacted.

Events

Old	New
'wagtail:breadcrumbs-expand'	'w-breadcrumbs:opened'
'wagtail:breadcrumbs-collapse'	'w-breadcrumbs:closed'

Data attributes

Old	New
data-breadcrumb-next	data-controller="w-breadcrumbs"
data-toggle-breadcrumbs	data-w-breadcrumbs-target="toggle" data-action="w-breadcrumbs#toggle mouseenter->w-breadcrumbs#peek"
data-breadcrumb-item	data-w-breadcrumbs-target="content"

Note that the root DOM element also includes a set of additional data attributes to function as the breadcrumbs:

data-controller="w-breadcrumbs"
data-action="keyup.esc@document->w-breadcrumbs#close w-breadcrumbs:open@document->w-breadcrumbs#open w-breadcrumbs:close@document->w-breadcrumbs#close"
data-w-breadcrumbs-close-icon-class="icon-cross"
data-w-breadcrumbs-closed-value="true"
data-w-breadcrumbs-open-icon-class="icon-breadcrumb-expand"
data-w-breadcrumbs-opened-content-class="w-max-w-4xl"
data-w-breadcrumbs-peek-target-value="header"
