 ## Features

-- change the default behaviour of the hardware button to act immediately on press down. Previously it has been acting on button release.
+- Add custom handlers on top of the standard modes as well. Previously this was only possible for mode == "custom".
+  - The goal here is to make it possible to move all input handling inside `setUI` where today some apps add on extra handlers outside of `setUI` calls.
+- Change the default behaviour of the hardware button to act immediately on press down. Previously it has been acting on button release.
+  - This makes the interaction slightly snappier.
+  - In addition to the existing `btn` key a new `btnRelease` key can now be specified. `btnRelease` will let you listen to the rising edge of the hardware button.
