## Upgrade considerations

### 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](https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/disabled) 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`
