 ### `Page.get_static_site_paths` method removed
 
 The undocumented `Page.get_static_site_paths` method (which returns a generator of URL paths for use by static site generator packages) has been removed. Packages relying on this functionality should provide their own fallback implementation.
+
+### Progress button (`button-longrunning`) now implemented with Stimulus
+
+The `button-longrunning` class usage has been updated to use the newly adopted Stimulus approach, the previous data attributes will be deprecated in a future release.
+
+If using the old approach, ensure any HTML templates are updated to the new approach before the next major release.
+
+### Old syntax
+
+```html+django
+<button type="submit" class="button action-save button-longrunning" data-clicked-text="{% trans 'Creating…' %}">
+  {% icon name="spinner" %}
+  <em>{% trans 'Create' %}</em>
+</button>
+```
+
+### New syntax
+
+Minimum required attributes are `data-controller` and a `data-action`.
+
+```html+django
+<button type="submit" class="button action-save button-longrunning" data-controller="w-progress" data-action="w-progress#activate" data-w-progress-active-value="{% trans 'Creating…' %}">
+  {% icon name="spinner" %}
+  <em data-w-progress-target="label">{% trans 'Create' %}</em>
+</button>
+```
+
+### Examples of additional capabilities
+
+Stimulus [targets](https://stimulus.hotwired.dev/reference/targets) and [actions](https://stimulus.hotwired.dev/reference/actions) can be leveraged to revise the behaviour via data attributes.
+
+* `<button ... data-w-progress-duration-value="500" ...>` - custom duration can be declared on the element
+* `<button ... class="custom-button" data-w-progress-active-class="custom-button--busy" ...>` - custom 'active' class to replace the default `button-longrunning-active` (must be a single string without spaces)
+* `<button ... ><strong data-w-progress-target="label">{% trans 'Create' %}</strong></button>` - any element can be the button label (not just `em`)
+* `<button ... data-action="w-progress#activate focus->w-progress#activate" ...>` - any event can be used to trigger the in progress behaviour
+* `<button ... data-action="w-progress#activate:once" ...>` - only trigger the progress behaviour once
+* `<button ... data-action="readystatechange@document->w-progress#activate:once" data-w-progress-duration-value="5000" disabled ...>` - disabled on load (once JS starts) and becomes enabled after 5s duration
