Wagtail 4.1 is designated a Long Term Support (LTS) release. Long Term Support releases will continue to receive maintenance updates as necessary to address security and data-loss related issues, up until the next LTS release (typically a period of 12 months).

What's new

"What's New" dashboard banner and "Help" menu

To help with onboarding new users, Wagtail now displays a banner on the dashboard, pointing users to our Editor Guide. The sidebar also contains a new "Help" menu item with a prominent indicator to call attention to the new content: a "What’s new" page showcasing new features, and a link to the Editor Guide.

Users can dismiss the new banner and the sidebar items’ indicators by interacting with the corresponding UI element. We store the state in the user’s profile so we only call attention to the content once.

To turn off the new banner, set WAGTAIL_ENABLE_WHATS_NEW_BANNER to False in your settings. The new menu items can be removed and customized with the following hooks:

• register_help_menu_item – to add new items to the "Help" menu
• construct_help_menu – to change or remove existing items from the "Help" menu
• construct_main_menu – to remove the new "Help" menu altogether

Page editor minimap

When navigating long page editing interfaces, it can be tedious to pinpoint a specific section, or find all validation errors. To help with those tasks, the page editor now has a new "minimap" side panel, with a table of contents of all sections on the form. Clicking a section’s label scrolls straight to this part of the page, and an indicator bar represents which sections are currently visible on the page. When validation errors are present, each section shows a count of the number of errors. This feature was implemented by Thibaud Colas based on a prototype by LB (Ben) Johnston.

New UI for scheduled publishing

Scheduled publishing settings can now be found within the Status side panel of the page editing view. This change aims to improve clarity over who can set schedules, and when they take effect. This feature was developed by Sage Abdullah.

Customizable snippet admin views

The register_snippet function now accepts a SnippetViewSet class, allowing various aspects of the snippet's admin views to be customized. See . This feature was developed by Sage Abdullah.

Scheduled publishing for snippets

Snippet models that inherit from DraftStateMixin can now be assigned go-live and expiry dates. This feature was developed by Sage Abdullah.

Object usage reporting

Images, documents and snippets now provide a usage report, listing the places where references to those objects appear. This report is powered by a new ReferenceIndex model which records cross-references between objects whenever those objects to save; this allows it to work more efficiently than the old report available through the WAGTAIL_USAGE_COUNT_ENABLED setting, as well as handling references within StreamField and rich text fields.

Note that on first upgrading to Wagtail 4.1, you will need to run the rebuild_references_index management command to populate the references table and ensure that reference counts are displayed accurately. By default, references are tracked for all models in the project, including ones not managed through Wagtail - to disable this for specific models, see .

This feature was developed by Karl Hobley and Matt Westcott.

Upgrade considerations

rebuild_references_index management command

After upgrading, you will need to run ./manage.py rebuild_references_index to populate the references table and ensure that usage counts for images, documents and snippets are displayed accurately. By default, references are tracked for all models in the project, including ones not managed through Wagtail - to disable this for specific models, see .

Recommend WagtailPageTestCase in place of WagtailPageTests

• WagtailPageTestCase is the base testing class and is now recommended over using WagtailPageTests .
• WagtailPageTests will continue to work and does log in the user on test setUp but may be deprecated in the future.

# class MyPageTests(WagtailPageTests): # old
class MyPageTests(WagtailPageTestCase): # new
    def setUp(self):
        # WagtailPageTestCase will not log in during setUp - so add if needed
        super().setUp()
        self.login()

    def test_can_create_a_page(self):
      # ...

Button styling class changes

The button-secondary class is no longer compatible with either the .serious or .no classes, this partially worked previously but is no longer officially supported.

When adding custom buttons using the ModelAdmin ButtonHelper class, custom buttons will no longer include the button-secondary class by default in index listings.

If using the hook register_user_listing_buttons to register buttons along with the undocumented UserListingButton class, the button-secondary class will no longer be included by default.

Avoid using disabled as a class on button elements, instead use the disabled attribute as support for this as a class may be removed in a future version of Wagtail and is not accessible.

If using custom expanding-formset the add button will no longer support the disabled class but instead must require the disabled attribute to be set.

The following button classes have been removed, none of which were being used within the admin but may have been used by custom code or packages:

• button-neutral
• button-strokeonhover
• hover-no
• unbutton
• yes

Dropped support for importing .xls Spreadsheet files into Redirects

• .xls legacy Microsoft Excel 97-2003 spreadsheets will no longer be supported for importing into the contrib Redirects listing.
• .xlsx, .csv, .tsv formats are still supported.
