 ## Unreleased
 
+### Enhancements
+
+-   Widgets: carry a widget's declarative `actions` from `widget.json` into
+    the generated PHP registry ([#80363](https://github.com/WordPress/gutenberg/pull/80363)).
+
+### Bug Fixes
+
+-   Pass the current `$hook_suffix` to the `admin_footer` action in the generated single-page admin template instead of an empty string ([#75985](https://github.com/WordPress/gutenberg/pull/75985)).
+
