-- Fixed the [`GetHapticCapabilitiesCommand`](xref:UnityEngine.InputSystem.XR.Haptics.GetHapticCapabilitiesCommand) always failing to execute due to a mismatch in the size in bytes of the payload and the size expected by XR devices. Changed [`HapticCapabilities`](xref:UnityEngine.InputSystem.XR.Haptics.HapticCapabilities) to include all properties returned by the XR input subsystem.

 - **The system no longer supports processing input in __BOTH__ fixed and dynamic updates**. Instead, a choice has to be made whether to process input before each `FixedUpdate()` or before each `Update()`.
   * Rationale: the existing code that supported having both updates receive input independently still had several holes and became increasingly complex and brittle. Our solution was based on not actually processing input twice but on channeling input concurrently into both the state of both updates. Together with the fact that specific inputs have to reset (and possibly accumulate) correctly with respect to their update time slices, this became increasingly hard to do right. This, together with the fact that we've come to increasingly question the value of this feature, led us to removing the capability while preserving the ability to determine where input is processed.
-  * NOTE: Timeslicing is NOT affected by this. You can still switch to `ProcessEventInFixedUpdates` and get events timesliced to individual `FixedUpdate` periods according to their timestamps.

 For most common scenarios, you do not need to use more than one Input Action Asset. It is usually simpler to configure your project-wide action definition in the Project Settings window.

 ### Using Action Assets with `PlayerInput`
 
-The [Player Input](PlayerInput.md) component provides a convenient way to handle input for one or multiple players. You can assign your Action Asset to the Player Input component so that it can then automatically handle activating Action Maps and selecting Control Schemes for you.

 ### Modifying Input Action Assets at runtime
-There are several ways to modify an Input Action Asset at runtime. Any modifications that you make during Play mode to an Input Action Asset do not persist in the Input Action Asset after you exit Play mode. This means you can test your application in a realistic manner in the Editor without having to worry about inadvertently modifying the asset. For examples on how to modify an Input Action Asset, see the documentation on [Creating Actions in code](Actions.md#creating-actions-in-code) and [Changing Bindings](ActionBindings.md#changing-bindings).

 ### The Default Actions Asset
 
-An asset called `DefaultInputActions.inputactions` containing a default setup of Actions comes with the Input System Package. You can reference this asset directly in your projects like any other Unity asset. However, the asset is also available in code form through the [`DefaultInputActions`](../api/UnityEngine.InputSystem.DefaultInputActions.html) class.
