- Introduced IScreenReaderNavigationPolicy. This is an interface class that helps the screen reader navigate to the appropriate target accessible widget.
- Introduced FScreenReaderDefaultNavigationPolicy. This is a policy that all FScreenReaderUsers have by default. It helps the screen reader user find target accessible widgets that are enabled and can be focused on.
- Introduced focus navigation functions to FScreenReaderUser. This is the means clients can control and shift accessible focus for FScreenReaderUsers.
- IAccessibleWidget can now retrieve the logical next and previous widget in the accessible widget hierarchy. This functionality is similar to that of mobile screen readers like Voiceover and Android Talkback which allow users to navigate around the UI hierarchy with left and right swipes.
- IAccessibleWidget can now search for a target widget from a source widget based on a search criteria. This is useful for searching for widgets by characteristics (such as enabled state, widget type etc).
- Fixed a small bug in accessible focus where an accessible widget with application focus cannot receive accessible focus again and have its contents announced to the end user.

- Moved FAccessibleEventArgs out of FGenericAccessibleMessageHandler to avoid the need to include GenericAccessibleInterfaces.h in header files where all
they really need is a forward declaration of the struct.
- Removed instances of FGenericAccessibleMessageHandler::FAccessibleEventArgs to FAccessibleEventArgs.
- Updated API for IAccessibleWidget and IAccessibleWindow that deal with getting and setting focus to also take a user index parameter. This facilitates multiple accessible users for the same application.
-Updated platform files that leverage the old IAccessibleWidget and IAccessibleWindow focus API
- Introduced FGenericAccessibleUser and FGenericAccessibleUserRegistry to GenericAccessibleInterfaces.h. An FGenericAccessibleUser is meant to be analogous to FSlateUser that keeps track of hardware users' focus. An FGenericAccessibleUserRegistry is a registry of FGenericAccessibleUsers. These interfaces are meant to insulate FGenericAccessibleMessageHandler from storing and tracking
focus etc when that should be an implementation detail by other modules.
- Refactored how FSlateCoreAccessibleWidgets set focus in the application. Accessible focus is now unified to a single code path that starts from FSlateAccessibleMessageHandler. Requests to shift accessible focus should be done by raising a Slate accessible event or through IAccessibleWidget::SetUserFocus()
- Introduced finer grain querying of focus capabilities for an IAccessibleWidget. Users can now check if an AccessibleWidget supports regular focus (keyboard/gamepad), if it supports accessible focus and if the widget can currently accept regular or accessible focus.
-Updated platforms to use the new FGenericAccessibleUser and FGenericAccessibleUserRegistry ApI to update and retrieve user focus.

-Adds support for getting velocity and accelleration through GetControllerTransformForTime.
-Adds mechanism for using openxr chain structs which are defined in and consumed by an extension plugin.
-Support for defining a swapchain and renderbridge in an extension plugin.
-Some OpenXR fixes related to runtimes not supplying tracking data of various types. Basically if the data isn't being provided we should not copy it out because it might be full of nonsense. Also we would generally rather preserve our last cached position than overwrite with zero/identity.
-Moving OpenXRPlatformRHI.h OpenXRHMD_RenderBridge.h and _Swapchain.h back to private folder.
-Previously one could not run the same haptic effect on two devices simultaneously and have it behave correctly because most of the per-effect-play data for each effect was shared by all controllers. This refactors so that the necessary runtime data is per controller and the constant bulk data is shared by all controllers.
-Adding infrastructure for playing haptics on a VR HMD.
-Refactored haptic data resampling into the oculus plugin because that is plugin specific.
