RadioButton and RadioGroup usage remains fully backward compatible.

Improvements:

• Event propagation from user interactions will now be canceled even if widgets are disabled. Previously, some relevant event propagation was not properly canceled.

• RadioButton now emits a ValueChange<bool> entity event when checked, even when checked via a RadioGroup. Consistent with other Checkable widgets. As a RadioButton cannot be unchecked through direct user interaction with this widget, a ValueChange event with value false can not be triggered for RadioButton.

• If a RadioButton is focusable, a value change event can be triggered using the Space or Enter keys when focused.

• RadioGroup is now optional and can be replaced with a custom implementation.
