+Removed deprecated APIs:
+
+- **`CascadeController`** and **`@cascades`** decorator are removed.
+  Use [`@lit/context`](https://lit.dev/docs/data/context/) instead for
+  sharing data between parent and child elements.
+- **`SlotController.anonymous`** is removed. Use `SlotController.default` instead.
+- **`pf-popover`**: the `close-label` attribute and `closeButtonLabel` property
+  are removed. Use `accessible-close-label` instead.
