 ## Unreleased
 
+### Deprecations
+
+-   Deprecate bottom margin on the following `BaseControl`-based components. Set the `__nextHasNoMarginBottom` prop to true to start opting into the new styles, which will become the default in a future version ([#64408](https://github.com/WordPress/gutenberg/pull/64408)).
