 - **Breaking:** The `driver_image` parameter of `boot::connect_controller` is
   now a `None`-terminated slice. Callers that previously passed `None` for this
   argument should pass in `&[]` instead.
+- **Breaking:** Corrected function signature of `boot::exit` to enable handling
+  errors during exit.
