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

### Other features

 * Add basic keyboard control and screen reader support for page listing re-ordering (Paarth Agarwal, Thomas van der Hoeven)
 * Add `PageQuerySet.private` method as an alias of `not_public` (Mehrdad Moradizadeh)
 * Most images in the admin will now only load once they are visible on screen (Jake Howard)
 * Allow setting default attributes on image tags [](adding_default_attributes_to_images) (Jake Howard)
 * Optimise the performance of the Wagtail userbar to remove duplicated queries, improving page loads when viewing live pages while signed in (Jake Howard)
 * Remove legacy styling classes for buttons and refactor button styles to be more maintainable (Paarth Agarwal, LB (Ben Johnston))
 * Add button variations to the pattern library (Paarth Agarwal)
 * Provide a more accessible page title where the unique information is shown first and the CMS name is shown last (Mehrdad Moradizadeh)
 * Pull out behaviour from `AbstractFormField` to `FormMixin` and `AbstractEmailForm` to `EmailFormMixin` to allow use with subclasses of `Page` [](form_builder_mixins) (Mehrdad Moradizadeh, Kurt Wall)
 * Add a `docs.wagtail.org/.well-known/security.txt` so that the security policy is available as per the specification on [https://securitytxt.org/](https://securitytxt.org/) (Jake Howard)
 * Add unit tests for the `classnames` Wagtail admin template tag (Mehrdad Moradizadeh)
 * Show an inverse locked indicator when the page has been locked by the current user in reports and dashboard listings (Vaibhav Shukla, LB (Ben Johnston))
 * Add clarity to the development documentation that `admonition` should not be used and titles for `note` are not supported, including clean up of some existing incorrect usage (LB (Ben Johnston))
 * Unify the styling of delete/destructive button styles across the admin interface (Paarth Agarwal)

### Bug fixes

 * Prevent `PageQuerySet.not_public` from returning all pages when no page restrictions exist (Mehrdad Moradizadeh)
 * Ensure that duplicate block ids are unique when duplicating stream blocks in the page editor (Joshua Munn)
 * Revise colour usage so that privacy & locked indicators can be seen in Windows High Contrast mode (LB (Ben Johnston))
 * Ensure that disabled buttons have a consistent presentation on hover to indicate no interaction is available (Paarth Agarwal)

## Upgrade considerations

### Button styling class changes

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.

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`
