## What's new

### Alt text accessibility check

The [built-in accessibility checker](authoring_accessible_content) now enforces a new `alt-text-quality` rule, which tests alt text for the presence of known bad patterns such as file extensions and underscores. This rule is enabled by default, but can be disabled if necessary.

This feature was implemented by Albina Starykova, with support from the Wagtail accessibility team.

### Word count and reading time metrics

The page editor’s Checks panel now displays two content metrics: word count, and reading time.
They are calculated based on the contents of the page preview.

This feature was developed by Albina Starykova and sponsored by The Motley Fool.

### Concurrent editing notifications

When multiple users concurrently work on the same content, Wagtail now displays notifications to inform them of potential editing conflicts. When a user saves their work, other users are informed and presented with options: they can refresh the page to view the latest changes, or proceed with their own changes, overwriting the other user's work.

Concurrent editing notifications are available for pages, and snippets. Specific messaging about conflicting versions is only available for pages and snippets with [support for saving revisions](wagtailsnippets_saving_revisions_of_snippets). To configure how often notifications are updated, use [`WAGTAIL_EDITING_SESSION_PING_INTERVAL`](wagtail_editing_session_ping_interval).

This feature was implemented by Matt Westcott and Sage Abdullah.

## Upgrade considerations - changes affecting all projects

### Specifying a dict of distribution IDs for CloudFront cache invalidation is deprecated

Previous versions allowed passing a dict for `DISTRIBUTION_ID` within the `WAGTAILFRONTENDCACHE` configuration for a CloudFront backend, to allow specifying different distribution IDs for different hostnames. This is now deprecated; instead, multiple distribution IDs should be defined as [multiple backends](frontendcache_multiple_backends), with a `HOSTNAMES` parameter to define the hostnames associated with each one. For example, a configuration such as:

```python
WAGTAILFRONTENDCACHE = {
    'cloudfront': {
        'BACKEND': 'wagtail.contrib.frontend_cache.backends.CloudfrontBackend',
        'DISTRIBUTION_ID': {
            'www.wagtail.org': 'your-distribution-id',
            'www.madewithwagtail.org': 'other-distribution-id',
        },
    },
}
```

should now be rewritten as:

```python
WAGTAILFRONTENDCACHE = {
    'mainsite': {
        'BACKEND': 'wagtail.contrib.frontend_cache.backends.CloudfrontBackend',
        'DISTRIBUTION_ID': 'your-distribution-id',
        'HOSTNAMES': ['www.wagtail.org'],
    },
    'madewithwagtail': {
        'BACKEND': 'wagtail.contrib.frontend_cache.backends.CloudfrontBackend',
        'DISTRIBUTION_ID': 'other-distribution-id',
        'HOSTNAMES': ['www.madewithwagtail.org'],
    },
}
```

### Changes to permissions registration for models with `ModelViewSet` and `SnippetViewSet`

Models registered with a `ModelViewSet` will now automatically have their {class}`~django.contrib.auth.models.Permission` objects registered in the Groups administration area. Previously, you need to use the [`register_permissions`](register_permissions) hook to register them.

If you have a model registered with a `ModelViewSet` and you registered the model's permissions using the `register_permissions` hook, you can now safely remove the hook.

If the viewset has {attr}`~wagtail.admin.viewsets.model.ModelViewSet.inspect_view_enabled` set to `True`, all permissions for the model are registered. Otherwise, the "view" permission is excluded from the registration.

To customize which permissions get registered for the model, you can override the {meth}`~wagtail.admin.viewsets.model.ModelViewSet.get_permissions_to_register` method.

This behavior now applies to snippets as well. Previously, the "view" permission for snippets is always registered regardless of `inspect_view_enabled`. If you wish to register the "view" permission, you can enable the inspect view:

```py
class FooViewSet(SnippetViewSet):
    ...
    inspect_view_enabled = True
```

Alternatively, if you wish to register the "view" permission without enabling the inspect view (i.e. the previous behavior), you can override `get_permissions_to_register` like the following:

```py
from django.contrib.auth.models import Permission
from django.contrib.contenttypes.models import ContentType

class FooViewSet(SnippetViewSet):
    def get_permissions_to_register(self):
        content_type = ContentType.objects.get_for_model(self.model)
        return Permission.objects.filter(content_type=content_type)
```

### Deprecation of `WAGTAIL_USER_EDIT_FORM`, `WAGTAIL_USER_CREATION_FORM`, and `WAGTAIL_USER_CUSTOM_FIELDS` settings

This release introduces a customizable `UserViewSet` class, which can be used to customize various aspects of Wagtail's admin views for managing users, including the form classes for creating and editing users. As a result, the [`WAGTAIL_USER_EDIT_FORM`, `WAGTAIL_USER_CREATION_FORM`, and `WAGTAIL_USER_CUSTOM_FIELDS` settings](user_form_settings) have been deprecated in favor of customizing the form classes via `UserViewSet.get_form_class()`.

If you use the aforementioned settings, you can migrate your code by making the following changes.

#### Before

Given the following custom user model:

```py
class User(AbstractUser):
    country = models.CharField(verbose_name='country', max_length=255)
    status = models.ForeignKey(MembershipStatus, on_delete=models.SET_NULL, null=True, default=1)
```

The following custom forms:

```py
class CustomUserEditForm(UserEditForm):
    status = forms.ModelChoiceField(queryset=MembershipStatus.objects, required=True, label=_("Status"))


class CustomUserCreationForm(UserCreationForm):
    status = forms.ModelChoiceField(queryset=MembershipStatus.objects, required=True, label=_("Status"))
```

And the following settings:

```py
WAGTAIL_USER_EDIT_FORM = "myapp.forms.CustomUserEditForm"
WAGTAIL_USER_CREATION_FORM = "myapp.forms.CustomUserCreationForm"
WAGTAIL_USER_CUSTOM_FIELDS = ["country"]
```

#### After

Change the custom forms to the following:

```py
class CustomUserEditForm(UserEditForm):
    status = forms.ModelChoiceField(queryset=MembershipStatus.objects, required=True, label=_("Status"))

    # Use ModelForm's automatic form fields generation for the model's `country` field.
    # Alternatively, you can also define a `country` form field directly on
    # `CustomUserEditForm` along with any desired options for the field, and skip
    # the following custom Meta subclass.
    class Meta(UserEditForm.Meta):
        fields = UserEditForm.Meta.fields | {"country"}

class CustomUserCreationForm(UserCreationForm):
    status = forms.ModelChoiceField(queryset=MembershipStatus.objects, required=True, label=_("Status"))

    # Use ModelForm's automatic form fields generation for the model's `country` field.
    # Alternatively, you can also define a `country` form field directly on
    # `CustomUserCreationForm` along with any desired options for the field, and skip
    # the following custom Meta subclass.
    class Meta(UserCreationForm.Meta):
        fields = UserEditForm.Meta.fields | {"country"}
```

Create a custom `UserViewSet` subclass in e.g. `myapp/viewsets.py`:

```py
# myapp/viewsets.py
from wagtail.users.views.users import UserViewSet as WagtailUserViewSet

from .forms import CustomUserCreationForm, CustomUserEditForm


class UserViewSet(WagtailUserViewSet):
    def get_form_class(self, for_update=False):
        if for_update:
            return CustomUserEditForm
        return CustomUserCreationForm
```

Create a custom `WagtailUsersAppConfig` subclass in e.g. `myapp/apps.py` (or reuse the same class if you have a custom `GroupViewSet` as described in [](customizing_group_views)). Then, set a `user_viewset` attribute pointing to the custom `UserViewSet` subclass:

```py
# myapp/apps.py
from wagtail.users.apps import WagtailUsersAppConfig


class CustomUsersAppConfig(WagtailUsersAppConfig):
    user_viewset = "myapp.viewsets.UserViewSet"
    # If you have customized the GroupViewSet before
    group_viewset = "myapp.viewsets.GroupViewSet"
```

Replace `wagtail.users` in `settings.INSTALLED_APPS` with the path to `CustomUsersAppConfig`:

```python
INSTALLED_APPS = [
    ...,
    "myapp.apps.CustomUsersAppConfig",
    # "wagtail.users",
    ...,
]
```

For more details, see [](custom_userviewset).

## Upgrade considerations - changes affecting Wagtail customisations

### Changes to report views with the new Universal Listings UI

The report views have been reimplemented to use the new Universal Listings UI, which introduces AJAX-based filtering and support for the `wagtail.admin.ui.tables` framework.
As a result, a number of changes have been made to the `ReportView` and `PageReportView` classes, as well as their templates.

If you have custom report views as documented in [](adding_reports), you will need to make the following changes.

#### Change `title` to `page_title`

The `title` attribute on the view class should be renamed to `page_title`:

```diff
 class UnpublishedChangesReportView(PageReportView):
-    title = "Pages with unpublished changes"
+    page_title = "Pages with unpublished changes"
```

#### Set up the results-only view

Set the `index_url_name` and `index_results_url_name` attributes on the view class:

```diff
 class UnpublishedChangesReportView(PageReportView):
+    index_url_name = "unpublished_changes_report"
+    index_results_url_name = "unpublished_changes_report_results"
```

and register the results-only view:

```diff
 @hooks.register("register_admin_urls")
 def register_unpublished_changes_report_url():
     return [
         path("reports/unpublished-changes/", UnpublishedChangesReportView.as_view(), name="unpublished_changes_report"),
+        # Add a results-only view to add support for AJAX-based filtering
+        path("reports/unpublished-changes/results/", UnpublishedChangesReportView.as_view(results_only=True), name="unpublished_changes_report_results"),
     ]
```

#### Adjust the templates

If you are only extending the templates to add your own markup for the listing table (and not other parts of the view template), you need to change the `template_name` into `results_template_name` on the view class.

For a page report, the following changes are needed:

- Change `template_name` to `results_template_name`, and optionally rename the template (e.g. `reports/unpublished_changes_report.html` to `reports/unpublished_changes_report_results.html`).
- The template should extend from `wagtailadmin/reports/base_page_report_results.html`.
- The `listing` and `no_results` blocks should be renamed to `results` and `no_results_message`, respectively.

```diff
 class UnpublishedChangesReportView(PageReportView):
-    template_name = "reports/unpublished_changes_report.html"
+    results_template_name = "reports/unpublished_changes_report_results.html"
```

```diff
 {# <project>/templates/reports/unpublished_changes_report_results.html #}

-{% extends "wagtailadmin/reports/base_page_report.html" %}
+{% extends "wagtailadmin/reports/base_page_report_results.html" %}

-{% block listing %}
+{% block results %}
     {% include "reports/include/_list_unpublished_changes.html" %}
 {% endblock %}
-{% block no_results %}
+{% block no_results_message %}
     <p>No pages with unpublished changes.</p>
 {% endblock %}
```

For a non-page report, the following changes are needed:

- Change `template_name` to `results_template_name`, and optionally rename the template (e.g. `reports/custom_non_page_report.html` to `reports/custom_non_page_report_results.html`).
- The template should extend from `wagtailadmin/reports/base_report_results.html`.
- Existing templates will typically define a `results` block containing both the results listing and the "no results" message; these should now become separate blocks named `results` and `no_results_message`.

**Before:**

```py
class CustomNonPageReportView(ReportView):
    template_name = "reports/custom_non_page_report.html"
```

```html+django
{# <project>/templates/reports/custom_non_page_report.html #}
{% extends "wagtailadmin/reports/base_report.html" %}

{% block results %}
    {% if object_list %}
        <table class="listing">
            <!-- Table markup goes here -->
        </table>
    {% else %}
        <p>No results found.</p>
    {% endif %}
{% endblock %}
```

**After:**

```py
class CustomNonPageReportView(ReportView):
    results_template_name = "reports/custom_non_page_report_results.html"
```

```html+django
{# <project>/templates/reports/custom_non_page_report_results.html #}
{% extends "wagtailadmin/reports/base_report_results.html" %}

{% block results %}
    <table class="listing">
        <!-- Table markup goes here -->
    </table>
{% endblock %}

{% block no_results_message %}
    <p>No results found.</p>
{% endblock %}
```


If you need to completely customize the view's template, you can still override the `template_name` attribute on the view class. Note that both `ReportView` and `PageReportView` now use the `wagtailadmin/reports/base_report.html` template, which now extends the `wagtailadmin/generic/listing.html` template. The `wagtailadmin/reports/base_page_report.html` template is now unused and should be replaced with `wagtailadmin/reports/base_report.html`.

If you override `template_name`, it is still necessary to set `results_template_name` to a template that extends `wagtailadmin/reports/base_report_results.html` (or `wagtailadmin/reports/base_page_report_results.html` for page reports), so the view can correctly update the listing and show the active filters as you apply or remove any filters.

## Upgrade considerations - changes to undocumented internals

### Deprecation of `window.ActivateWorkflowActionsForDashboard` and `window.ActivateWorkflowActionsForEditView`

The undocumented usage of the JavaScript `window.ActivateWorkflowActionsForDashboard` and `window.ActivateWorkflowActionsForEditView` functions will be removed in a future release.

These functions are only used by Wagtail to initialize event listeners to workflow action buttons via inline scripts and are never intended to be used in custom code. The inline scripts have been removed in favour of initializing the event listeners directly in the included `workflow-action.js` script. As a result, the functions no longer need to be globally-accessible.

Any custom workflow actions should be done using the [documented approach for customising the behavior of custom task types](custom_tasks_behavior), such as by overriding `Task.get_actions()`.
