 - Fixed the compilation warnings when used with Unity 6.4 (ISX-2349).
 - Fixed an issue where `InputSystemUIInputModule.localMultiPlayerRoot` could not be set to `null` when using `MultiplayerEventSystem`. [ISXB-1610](https://issuetracker.unity3d.com/product/unity/issues/guid/ISXB-1610)
 - Fixed an issue in `Keyboard` where the sub-script operator would return a `null` key control for the deprecated key `Key.IMESelected`. Now, an aliased `KeyControl`mapping to the IMESelected bit is returned for compability reasons. It is still strongly advised to not rely on this key since `IMESelected` bit isn't strictly a key and will be removed from the `Key` enumeration type in a future major revision. [ISXB-1541](https://issuetracker.unity3d.com/product/unity/issues/guid/ISXB-1541).
+- Fixed an issue where the onAnyButtonPress callback would be triggered multiple times during unrelated events when a button is held down. See [ISXB-1005](https://issuetracker.unity3d.com/product/unity/issues/guid/ISXB-1005).
