OpenXR SDK 1.1.60 (2026-05-20)

This release contains support for a new multi-vendor extension, as well as many
fixes and cleanups to the layers and loader.

• SDK
  • API Dump Layer: Fix: Prevent runtime failure when encountering an unknown
    XrStruct.
    (internal MR 4301)
  • API Dump Layer: Fix: Prevent crashes when using extension function pointers
    without the extension enabled.
    (internal MR 4301,
    internal issue 2524)
  • API Dump Layer: Fix: Data race due to map access outside the mutex lock in both
    create and destroy paths for handle dispatch maps.
    (internal MR 4301)
  • API Dump Layer: Fix: Generated code attempting to read uninitialized char*
    buffers.
    (internal MR 4301)
  • Best Practices Layer: Fix: Resolve invalid reference.
    (internal MR 4273,
    internal issue 2683,
    OpenXR-SDK-Source issue 588)
  • Improvement: Loader: Minor code cleanups without functional change.
    (internal MR 4264)
  • Improvement: Enable -Wc++20-extensions.
    (internal MR 4265)
  • Improvement: Enable sanitizers for all CMake projects.
    (internal MR 4296,
    internal MR 2743)
  • Improvement: Add CMake test to run the CTS with the
    XR_APILAYER_LUNARG_api_dump layer and test runtime (when layer and CTS are in
    a single unified repo).
    (internal MR 4301)
  • Improvement: Add CMake test to run the CTS with the
    XR_APILAYER_LUNARG_core_validation layer and test runtime (when layer and CTS
    are in a single unified repo).
    (internal MR 4306)
  • Loader: Improvement: Refactor LoaderXrGetInstanceProcAddr to avoid repeated
    strcmp on names and a hypothetical null dereference.
    (internal MR 3132)
  • Loader: Improvement: Several code cleanups and optimizations.
    (internal MR 4254,
    internal MR 4255,
    internal MR 4257,
    internal MR 4263)
  • Loader: Fix: Use strtoul instead of atoi/strtol for unsigned integer
    parsing in manifest files.
    (internal MR 4258)
  • Loader: Fix: Fix wrong VUID in empty application name error message.
    (internal MR 4262)
  • Loader: Fix: stack-use-after-scope problem in manifest_file.cpp. (included
    in 1.1.59.1 hotfix as well)
    (internal MR 4295,
    internal MR 2743)
  • Validation Layer: Fix: Verify downstream extension function support before
    returning layer wrapper.
    (internal MR 4306)
  • Validation Layer: Fix: Return xrCreateApiLayerInstance errors immediately.
    (internal MR 4306)
  • Validation Layer: Fix: Return warning rather than error for unknown enum values
    so the runtime can return the correct error code.
    (internal MR 4306)
  • Validation Layer: Fix: Skip enum validation for
    xrResultToString/xrStructureTypeToString since these functions accept any
    value by design.
    (internal MR 4306)
  • Validation Layer: Fix: Skip strlen() on non-const output char arrays to avoid
    undefined behavior on uninitialized buffers.
    (internal MR 4306)
  • Validation Layer: Fix: Destroy implicitly-created debug utils messengers during
    instance teardown to prevent handle leaks.
    (internal MR 4306)
• Registry
  • New multi-vendor extension: XR_EXT_haptic_parametric
    (internal MR 3307)
  • Change: Deprecate HoloLens 2 related extensions.
    (internal MR 4133)
  • Change: Mark XR_ANDROID_trackables and its child extensions as deprecated by
    various XR_EXT and XR_ANDROID spatial entity extensions.
    (internal MR 4228)
  • Fix: Add comment for enum value XR_SPACE_COMPONENT_TYPE_ROOM_MESH_META in
    xr.xml.
    (internal MR 4292,
    internal issue 2740)
  • Fix: Add comment for result value
    XR_BOUNDARY_VISIBILITY_SUPPRESSION_NOT_ALLOWED_META in xr.xml.
    (internal MR 4293,
    internal issue 2739)
  • Fix: Mark XrSessionCreateInfoOverlayEXTX::createFlags as optional.
    (internal MR 4302)
  • Fix: Update XrFoveationEyeTrackedProfileCreateInfoMETA to mark flags as
    optional
    (internal MR 4317,
    internal MR 4317)
  • Improvement: Add schematron validation for optional required for empty bit
    flags.
    (internal MR 4317,
    internal issue 2745)
  • Scripts: Handle deprecation expressions referring to multiple extensions.
    (internal MR 4228)
