OpenXR SDK 1.1.40 (2024-08-22)

This release features a new ratified graphics API binding extension,

OpenXR SDK 1.1.38

OpenXR SDK 1.1.38 (2024-06-09)

This is a fairly small release, with one new extension and a handful of fixes.

      "structextends" (in the next chain). Bump extension revision.

OpenXR SDK 1.1.37 (2024-05-23)

This release primarily adds new defines for easier use of both OpenXR 1.0 and
1.1 with up-to-date headers, some documentation improvements, and improvements
for Android, including support for using the "API Dump" and "Validation" API
layers in your own APK during the development process.

OpenXR SDK 1.1.36

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)

OpenXR SDK 1.0.33

OpenXR SDK 1.0.33 (2024-01-03)

This release primarily adds new ratified functionality describing the loader
interaction with runtimes and API layers. Corresponding definitions are now in
the official openxr_loader_negotiation.h generated header, rather than the
loader_interfaces.h header previously shipped only with the OpenXR-SDK-Source
repository. This change only affects vendors of runtimes and API layers as well
as contributors to the OpenXR loader: applications do not directly use this API,
the loader uses it on their behalf. A number of other small fixes are also
included.

  • Registry
    • Extension reservation: Update author ID and reserve extensions for Varjo.
      (internal MR 3083)
    • Extension reservation: Reserve 10 extension ids each for ANDROIDX &
      ANDROIDSYS.
      (internal MR 3086)
    • Khronos ratified addition: Specify the existing loader negotiation functions
      (without modification) in the XML, moving from loader_interfaces.h to a new
      generated header openxr_loader_negotiation.h.
      (internal MR 2807,
      internal issue 1953)
    • XR_KHR_android_thread_settings: Fix the description of
      XrAndroidThreadTypeKHR enum values - they were swapped relative to their
      implicit meaning from their name.
      (internal MR 3077)
    • XR_MNDX_egl_enable: Update version to 2 to reflect function pointer type
      change released in 1.0.29.
      (OpenXR-Docs PR 159)
  • SDK
    • Loader: Fix loader build on Universal Windows Platform: build-system-only
      change. (Included in SDK hotfix 1.0.32.1.)
      (internal MR 3071)
    • Loader: Correctly destroy the LoaderInstance when loader is done.
      (internal MR 3041)
    • Remove obsolete loader_interfaces.h header, migrating uses (in loader and
      layers) to use the newly specified and ratified openxr_loader_negotiation.h,
      and adjust scripts for the addition of the loader negotiation APIs.
      (internal MR 2807,
      internal issue 1953,
      internal MR 3122)
  • Misc
    • Update/correct names.
    • Ship a .mailmap file in the public repositories, maintained separately
      from the larger one used in the private monorepo, to correct names/emails
      and unify contributor identities.
    • Update Khronos Group copyright dates.

OpenXR SDK 1.0.32

OpenXR SDK 1.0.32 (2023-11-29)

This release contains a number of vendor extensions, plus a new ratified
revision to the XR_KHR_loader_init extension that specifies forwarding the
init calls to API layers. Vendors of API layers, primarily on Android, must
verify they can handle being passed XR_NULL_HANDLE for the instance parameter
of xrGetInstanceProcAddr, to avoid bugs when using the updated loader. This
release also contains a number of build system cleanups and fixes. Users of the
Android Gradle Plugin and our official loader AAR file can now use the
OpenXR::headers target just like on desktop: there is now metadata for the
"prefab" tool to generate for CMake both this header/include-only target and the
normal OpenXR::openxr_loader imported library target. The shipped AAR is much
smaller due to stripping debug data from the binaries, which helps in case
application build systems do not automatically strip native binaries. A bug in
the loader Android manifest as shipped in 1.0.31 has also been fixed.
