OpenXR Specification 1.1.61 (2026-07-02)

This release primarily features a number of new vendor extensions, plus one
vendor extension fix, clarifications for spatial entities, and additional sample
code cleanup. A small addition to the reflection headers is also included.

• Specification
  • Fix: Typos in enum value names for XrTrackingOptimizationSettingsHintQCOM.
    (internal MR 4186)
  • Fix: Miscellaneous non-normative fixes to the XR_EXT_spatial_entity spec
    language.
    (internal MR 4355)
  • Improvement: Improve consistency of struct initialization patterns in adoc
    sample code, using designated initializers for clarity in additional sample
    code not converted in the last release.
    (internal MR 4248,
    internal MR 4247,
    internal MR 4246,
    internal MR 4374)
  • New vendor extension specification: XR_ANDROID_spatial_discovery_bounds to
    enable limiting discovery of spatial entities to within a sphere, box, or
    frustum.
    (internal MR 3520)
  • New vendor extension specification: XR_BD_body_tracking_auxiliary_metrics
    provides additional data about body tracking state and the ability to trigger
    the runtime to begin its calibration process.
    (internal MR 3756)
  • New vendor extension specification: XR_META_hand_tracking_frequency_hint
    providing a way for applications to inform the runtime they would prefer higher
    frequency, lower latency tracking with tradeoffs.
    (internal MR 4110)
  • New vendor extension specification:
    XR_META_hand_tracking_unextrapolated_poses for use by specialized
    applications that may have additional context for hand tracking extrapolation
    not available to the runtime.
    (internal MR 4113)
  • New vendor extension specification: XR_META_hand_tracking_wide_motion_mode2
    adding another hand tracking data source that performs wider-range tracking
    even outside of the view of the cameras.
    (internal MR 4114)
  • New vendor extension specification: XR_ANDROID_google_cloud_auth to give a
    way for apps to send their Google Cloud auth info to the runtime.
    (internal MR 4200)
  • New vendor extension specification: XR_ANDROID_geospatial to convert a WGS84
    GeoPose to an XrPosef and vice-versa using vendor cloud services.
    (internal MR 4201)
  • New vendor extension specification: XR_ANDROID_geospatial_anchor to provide
    geospatial & surface anchors.
    (internal MR 4214)
  • New vendor extension specifications: XR_BD_dynamic_object_tracking vendor
    spatial sensing related extension, with related XR_BD_dynamic_object_keyboard
    (for tracking a computer keyboard) and XR_BD_dynamic_object_mouse (for
    tracking a computer mouse) extensions.
    (internal MR 3944)
• Registry
  • Fix: Typos in enum value names for XrTrackingOptimizationSettingsHintQCOM.
    Original names left as aliases for source compatibility.
    (internal MR 4186)
  • Improvement: XR_LIST_FUNCTIONS_ macros in the reflection header are now
    generated for all features, even those lacking functions.
    (internal MR 4329)
  • New vendor extension: XR_ANDROID_spatial_discovery_bounds
    (internal MR 3520)

    (internal MR 3944)
  • New vendor extension: XR_BD_dynamic_object_keyboard
    (internal MR 3944)

    (internal MR 4214)
  • Schematron: Add exception for the comments of a behavior-only
    XrSpatialComponentTypeEXT.
