OpenXR SDK 1.1.36 (2024-04-15)

This is a substantial update to the OpenXR specification. The OpenXR loader in
this release supports both OpenXR 1.0 and 1.1, and sample applications such as
hello_xr continue to only require OpenXR 1.0. The schema associated with the
xr.xml description of OpenXR has received a small but breaking change, so
software that parses it may need an update accordingly. Additionally, the
protocol for the OpenXR loader on Android to communicate with system or
installable runtime brokers has been extended for improvfed backward- and
forward-compatibility; see the changes to the loader design document for more
information.

  • Registry
    • New ratified Khronos extension: XR_KHR_locate_spaces
      (internal MR 2272,
      internal issue 1706)
    • New ratified Khronos extension: XR_KHR_maintenance1
      (internal MR 3053)
    • New ratified OpenXR version: XR_VERSION_1_1 - OpenXR 1.1.
      (internal MR 3053)
    • New multi-vendor extension: XR_EXT_future
      (internal MR 2610)
    • New vendor extension: XR_META_environment_depth
      (internal MR 2771,
      internal MR 3271)
    • Mark XR_OCULUS_android_session_state_enable as deprecated.
      (internal MR 3255)
    • Update the XML schema to change how dependencies are described (replacing
      requiresCore and requires attributes of extension, and feature and
      extension attributes of require, with a new depends attribute.). This is
      a breaking change of the XML schema, though in an infrequently processed
      attribute. This corresponds to the change made in Vulkan 1.3.241.
      (internal MR 3260)
  • SDK
    • API dump layer: Handle opaque futures defined by XR_EXT_future.
      (internal MR 2610)
    • API dump layer: Zero initialize out-param in calls to xrResultToString and
      xrStructureTypeToString.
      (internal MR 3284)
    • Android loader: Build using NDK 23.2.
      (internal MR 2992)
    • Android loader: Allow the loader to check multiple records from the broker, for
      backward- and forward-compatibility
      (internal MR 3269,
      internal issue 2226)
    • Loader: Improve error logging in the case that the Windows registry
      ActiveRuntime path cannot be parsed or found.
      (internal MR 3015,
      internal issue 2125)
    • Loader: Remove path separator parsing from Windows registry ActiveRuntime
      path to fix bug.
      (internal MR 3015)
    • Loader: Fix build issue for ARMv6 architectures, and note architecture naming
      quirk of Raspberry Pi OS in the architecture table in the loader documentation.
      (OpenXR-SDK-Source PR 464,
      OpenXR-SDK-Source issue 463)
    • Reduce duplication of environment variable getters and setters.
      (internal MR 3039)
    • Updates to scripts and software to handle aliases and promoted functionality in
      XR_KHR_maintenance1 and XR_VERSION_1_1
      (internal MR 3053)
    • hello_xr: Fix Windows mirror window acquire, wait, present loop.
      (internal MR 3289)
    • hello_xr and other samples: Update Android compile SDK version (to 33), NDK
      version (to 23.2), and build tools version (to 34.0.0).
      (internal MR 2992)
    • hello_xr and runtime list: Request an OpenXR 1.0 instance by default.
      (internal MR 3320)
    • loader_test: Build fixes to allow loader_test to compile / run on Android.
      (internal MR 3153)

The Android loader can be found on Maven Central, by adding the following line to your Android app's build.gradle dependencies section:

implementation 'org.khronos.openxr:openxr_loader_for_android:1.1.36'

(There may be a delay of a few hours after release before artifacts are accessible on Maven Central.)
