Wagtail 1.12 release notes

Wagtail 1.12 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 8 months). Please note that Wagtail 1.12 will be the last LTS release to support Python 2.

What’s new

Configurable rich text features

The feature set provided by the rich text editor can now be configured on a per-field basis, by passing a features keyword argument; for example, a field can be configured to allow bold / italic formatting and links, but not headings or embedded images or media. For further information, see Limiting features in a rich text field. This feature was developed by Matt Westcott.

Improved embed configuration

New configuration options for embedded media have been added, to give greater control over how media URLs are converted to embeds, and to make it possible to specify additional media providers beyond the ones built in to Wagtail. For further information, see Embedded content. This feature was developed by Karl Hobley.

Upgrade considerations

StreamField now defaults to blank=False

StreamField now respects the blank field setting; when this is false, at least one block must be supplied for the field to pass validation. To match the behaviour of other model fields, blank defaults to False; if you wish to allow a StreamField to be left empty, you must now add blank=True to the field.

Old configuration settings for embeds are deprecated

The configuration settings WAGTAILEMBEDS_EMBED_FINDER and WAGTAILEMBEDS_EMBEDLY_KEY have been deprecated in favour of the new WAGTAILEMBEDS_FINDERS setting. Please see Configuring embed “finders” for the new configuration to use.

Registering custom hallo.js plugins directly is deprecated

The ability to enable / disable hallo.js plugins by calling registerHalloPlugin or modifying the halloPlugins list has been deprecated, and will be removed in Wagtail 1.14. The recommended way of customising the hallo.js editor is now through rich text features. For details of how to define a hallo.js plugin as a rich text feature, see Extending the WYSIWYG Editor (hallo.js).

Custom get_admin_display_title methods should use draft_title

This release introduces a new draft_title field on page models, so that page titles as used across the admin interface will correctly reflect any changes that exist in draft. If any of your page models override the get_admin_display_title method, to customise the display of page titles in the admin, it is recommended that you now update these to base their output on draft_title rather than title. Alternatively, to preserve backwards compatibility, you can invoke super on the method, for example:

def get_admin_display_title(self):
    return "%(title)s (%(lang)s)" % {
        'title': super(TranslatablePage, self).get_admin_display_title(),
        'lang': self.language_code,
    }

Fixtures for loading pages should include draft_title

In most situations, the new draft_title field on page models will automatically be populated from the page title. However, this is not the case for pages that are created from fixtures. Projects that use fixtures to load initial data should therefore ensure that a draft_title field is specified.

RoutablePageMixin now has a default index route

If you’ve used RoutablePageMixin on a Page model, you may have had to manually define an index route to serve the page at its main URL (r'^$') so it behaves like a normal page. Wagtail now defines a default index route so this is no longer required.
