OpenXR SDK 1.1.62 (2026-07-31)

This release includes a new vendor extension, an important fix to several vendor
extension added in the previous release, a loader design doc clarification, and
some software fixes and cleanup. For extension authors, there are workflow
improvements: extensions may now be developed in their own "fragment" XML file
and referenced from xr.fragmented.xml. Provided tooling processes this file to
generate the all-inclusive xr.xml previously edited directly. This reduces the
merge conflicts seen during extension development and makes review easier,
without requiring changes to tools expecting the conventional combined XML file.

• SDK
  • Fix: Only include EGL headers in xr_dependencies.h when using EGL or GLES.
    (internal MR 4387)
  • Improvement: Add src/common/platform_exports.h to de-duplicate platform
    specific export flags.
    (internal MR 4323)
  • Improvement: Add additional description of Android API layer support.
    (internal MR 4373)
  • Improvement: Deduplicate .def, .expsym, and .map files used for API
    layers in the SDK.
    (internal MR 4389,
    internal MR 3289)
• Registry
  • Change: XML registry xr.xml is now checked in after being constructed from
    xr.fragmented.xml and multiple per-extension XML file fragments, for reduced
    conflicts during development. The schema of xr.xml has not changed. Be sure
    to run specification/scripts/merge-registry.sh after editing
    xr.fragmented.xml or one of the fragments, as most tooling still uses the
    merged XML registry.
    (internal MR 4161)
  • Chore: Register DXR author ID for The DisplayXR Project.
    (OpenXR-Docs PR 201)
  • Fix: Resolve inconsistency between extension numbers for META vendor extensions
    (XR_META_hand_tracking_wide_motion_mode2,
    XR_META_hand_tracking_frequency_hint,
    XR_META_hand_tracking_unextrapolated_poses).
    (internal MR 4380)
  • Fix: Add XR_ERROR_LIMIT_REACHED as an valid return for
    xrAcquireEnvironmentDepthImageMETA matching API description.
    (internal MR 4414)
  • Improvement: Move XR_ANDROID_trackables to extension fragment XML file.
    (internal MR 4161)
  • Improvement: Add explicit type includes for types that are implicitly included
    to improve generated documentation.
    (internal MR 4406,
    internal MR 4413)
  • New vendor extension: XR_SONY_swapchain_color_space
    (internal MR 4171)
