OpenXR SDK 1.1.65 (2026-10-16)

This release adds an alternate mode to the Hello XR sample app that demonstrates
the use of the recent XR_EXT_spatial_containers functionality. It also
includes a loader robustness fix, some API layers fixes, and some correctness
and compatibility fixes, in addition to the registry updates for the new
extensions that allow the supplied layers to generate code handling those
extensions.

• SDK
  • API dump layer: Fix: Treat jobject as an external handle.
    (internal MR 4477,
    internal MR 4435)
  • Documentation: Update build documentation for the switch to C++17: correct the
    minimum Visual Studio version in the OpenXR-SDK readme to VS 2017, and remove
    description of C++17 and its filesystem library as not yet released in the
    loader design document.
    (internal MR 4519)
  • Fix: Re-add tests for invalid runtime json files in loader_test.
    (internal MR 4430)
  • Fix: Make requirement for OpenGLES 3.1 more consistent.
    (internal MR 4455)
  • Fix: Avoid assuming uint32_t is unsigned int in sscanf writes in manifest
    version parsing in the loader.
    (internal MR 4458)
  • Fix: Avoid leaking component extension availability into interaction profile
    availability in interaction_profile_processor.py.
    (internal MR 4515)
  • Improvement: Remove pre-C++17 filesystem code from the SDK.
    (internal MR 4429,
    internal issue 2682)
  • Improvement: Remove XrResult enum length check.
    (internal MR 4462,
    internal MR 4435)
  • Loader: Fix API layer enumeration on Windows when encountering invalid registry
    key.
    (internal MR 4440)
  • Validation Layer: Fix: Guard handles defined in platform-specific extensions in
    the generated code.
    (internal MR 4552)
  • hello_xr: Add example code and Android manifest entries for spatial containers.
    A new command line option, --program, or adb shell setprop debug.xr.program, allows choosing between the existing example code and the
    new spatial container example code.
    (internal MR 4412,
    internal MR 4566)
  • hello_xr: Improvement: Remove some unused code.
    (internal MR 4562)
  • hello_xr: Fix: format string size mismatch
    (OpenXR-SDK-Source PR 616)
• Registry
  • Change: Mark XR_ANDROID_trackables_image deprecated by
    XR_EXT_spatial_image_tracking and XR_ANDROID_unbounded_reference_space
    deprecated by XR_EXT_stationary_reference_space.
    (internal MR 4488)
  • Chore: Reserve extensions.
    (internal MR 4512,
    internal MR 4561)
  • Fix: Fix formatting and markup issues in XML enum comments.
    (internal MR 4523)
  • Fix: Remove listing of XR_EXT_uuid as a dependency for extensions as it is
    not required to be enabled.
    (internal MR 4563)
  • Improvement: Swap enum alias for XR_SWAPCHAIN_USAGE_INPUT_ATTACHMENT_BIT_KHR
    and XR_SWAPCHAIN_USAGE_INPUT_ATTACHMENT_BIT_MND. No functional change to
    header users, only affects consumers of the XML registry.
    (internal MR 4506,
    internal issue 2228,
    OpenXR-Docs issue 166)
  • New ratified multi-vendor extension: XR_EXT_spatial_object_tracking
    (internal MR 3877)
  • New ratified multi-vendor extension: XR_EXT_aosp_hand_tracking_permission
    (internal MR 3908,
    internal issue 2040,
    internal MR 3766,
    internal MR 3866,
    internal MR 4003)
  • New ratified multi-vendor extension: XR_EXT_spatial_mesh_tracking
    (internal MR 3929)
  • New ratified multi-vendor extension: XR_EXT_spatial_entity_archetypes
    (internal MR 4061)
  • New ratified multi-vendor extension: XR_EXT_spatial_plane_semantic_label2
    (internal MR 4129)
  • New ratified multi-vendor extensions: XR_EXT_app_consumed_swapchain and
    XR_EXT_enumerate_swapchain_formats2
    (internal MR 3852)
  • New vendor extension: XR_BD_motion_tracker
    (internal MR 4148)
  • Schematron: Validate that an XrObjectType enum exists for every handle.
    (internal MR 4395)
  • Schematron: Add validation that vendor / author ID on flag bits matches
    extension.
    (internal MR 4463)
  • Schematron: Add rules to catch partially-documented enums, which will have
    undocumented elements omitted from documentation.
    (internal MR 4464,
    internal issue 2783)
  • Schematron: Add rules to catch duplicate enums in the registry.
    (internal MR 4467,
    internal issue 2783)
  • Schematron: Validate that all commands and types are required by a feature.
    (internal MR 4485)
  • Schematron: Add validation that XR_ERROR_ prefixed XrResult values have are
    negative.
    (internal MR 4500)
  • Schematron: Add assertion IDs, and document this pattern.
    (internal MR 4503)
  • Schematron: Enforce that negative schema self-test cases only fail at most one
    assertion (unless explicitly annotated with expected failures), prevent
    cascading assertion failures in Schematron rules, and standardize test
    assertion IDs.
    (internal MR 4504,
    internal MR 4526)
  • Schematron: Apply PrettyRegistryXml.OpenXR to the Schematron test files.
    (internal MR 4516,
    internal MR 4554)
  • Schematron: Disallow empty comments on enumerants.
    (internal MR 4523)
  • Scripts: Allow generating reserved extension stubs from stubs="true"
    placeholders in xr.fragmented.xml at merge time, and update Schematron
    validation for stub placeholders. (The complete, merged XML file has not
    changed its schema.)
    (internal MR 4482)
  • Scripts: Ignore hidden files when scanning for per-extension XML files.
    (internal MR 4492)
  • Scripts: Create pretty_all.py to format all XML registry files and registry
    fragment files in this repository.
    (internal MR 4516,
    internal MR 4554)
