Wagtail 2.13 release notes

What’s new

StreamField performance and functionality updates

The StreamField editing interface has been rebuilt on a client-side rendering model, powered by the telepath library. This provides better performance, increased customisability and UI enhancements including the ability to duplicate blocks. For further background, see the blog post Telepath - the next evolution of StreamField.

This feature was developed by Matt Westcott and Karl Hobley and sponsored by YouGov, inspired by earlier work on react-streamfield completed by Bertrand Bordage through the Wagtail’s First Hatch crowdfunder.

Simple translation module

In Wagtail 2.12 we shipped the new localisation support, but in order to translate content an external library had to be used, such as wagtail-localize.

In this release, a new contrib app has been introduced called simple_translation. This allows you to create copies of pages and translatable snippets in other languages and translate them as regular Wagtail pages. It does not include any more advanced translation features such as using external services, PO files, or an interface that helps keep translations in sync with the original language.

This module was contributed by Coen van der Kamp.


The page editor now supports leaving comments on fields and StreamField blocks, by entering commenting mode (using the button in the top right of the editor). Inline comments are available in rich text fields using the Draftail editor.

This feature was developed by Jacob Topp-Mugglestone, Karl Hobley and Simon Evans and sponsored by The Motley Fool.

Combined account settings

The “Account settings” section available at the bottom of the admin menu has been updated to include all settings on a single form. This feature was developed by Karl Hobley.

Redirect export

The redirects module now includes support for exporting the list of redirects to XLSX or CSV. This feature was developed by Martin Sandström.

Sphinx Wagtail Theme

The documentation now uses our brand new Sphinx Wagtail Theme, with a search feature powered by Algolia DocSearch.

Feedback and feature requests for the theme may be reported to the sphinx_wagtail_theme issue list, and to Wagtail’s issues for the search.

Thank you to Storm Heg, Tibor Leupold, Thibaud Colas, Coen van der Kamp, Olly Willans, Naomi Morduch Toubman, Scott Cranfill, and Andy Chosak for making this happen!

Upgrade considerations

End of Internet Explorer 11 support

Wagtail 2.13 will be the last Wagtail release to support IE11. Users accessing the admin with IE11 will be shown a warning message advising that support is being phased out.

Updated handling of non-required StreamFields

The rules for determining whether a StreamField is required (i.e. at least one block must be provided) have been simplified and made consistent with other field types. Non-required fields are now indicated by blank=True on the StreamField definition; the default is blank=False (the field is required). In previous versions, to make a field non-required, it was necessary to define a top-level StreamBlock with required=False (which applied the validation rule) as well as setting blank=True (which removed the asterisk from the form field). You should review your use of StreamField to check that blank=True is used on the fields you wish to make optional.

New client-side implementation for custom StreamField blocks

For the majority of cases, the new StreamField implementation in this release will be a like-for-like upgrade, and no code changes will be necessary - this includes projects where custom block types have been defined by extending StructBlock, ListBlock and StreamBlock. However, certain complex customisations may need to be reimplemented to work with the new client-side rendering model:

  • When customising the form template for a StructBlock using the form_template attribute, the HTML of each child block must be enclosed in an element with a data-contentpath attribute equal to the block’s name. This attribute is used by the commenting framework to attach comments to the correct fields. See Custom editing interfaces for StructBlock.
  • If a StructBlock subclass overrides the get_form_context method as part of customising the form template, and that method contains logic that causes the returned context to vary depending on the block value, this will no longer work as intended. This is because get_form_context is now invoked once with the block’s default (blank) value in order to construct a template for the client-side rendering to use; previously it was called for each block in the stream. In the new implementation, any Python-side processing that needs to happen on a per-block-value basis can be performed in the block’s get_form_state method; the data returned from that method will then be available in the client-side render method.
  • If FieldBlock is used to wrap a Django widget with non-standard client-side behaviour - such as requiring a JavaScript function to be called on initialisation, or combining multiple HTML elements such that it is not possible to read or write its data by accessing a single element’s value property - then you will need to supply a JavaScript handler object to define how the widget is rendered and populated, and how to extract data from it.
  • Packages that replace the StreamField interface at a low level, such as wagtail-react-streamfield, are likely to be incompatible (but the new StreamField implementation will generally offer equivalent functionality).

For further details, see How to build custom StreamField blocks.

Switched register_setting, register_settings_menu_item to use SVG icons

Setting menu items now use SVG icons by default. For sites reusing built-in Wagtail icons, no changes should be required. For sites using custom font icons, update the menu items’ definition to use the classnames attribute:

# With register_setting,
# Before:
# After:
@register_setting(icon='', classnames='icon icon-custom-cog')

# Or with register_settings_menu_item,
def register_frank_menu_item():
    # Before:
    return SettingMenuItem(CustomSetting, icon='custom-cog')
    # After:
    return SettingMenuItem(CustomSetting, icon='', classnames='icon icon-custom-cog')


Page.settings_panels now includes CommentPanel, which is used to save and load comments. If you are overriding page settings edit handlers without directly extending Page.settings_panels (ie settings_panels = Page.settings_panels + [ FieldPanel('my_field') ] would need no change here) and want to use the new commenting system, your list of edit handlers should be updated to include CommentPanel. For example:

from django.db import models

from wagtail.core.models import Page
from wagtail.admin.edit_handlers import CommentPanel

class HomePage(Page):
    settings_panels = [
        # My existing panels here


We would love to receive your feedback on this release.
