OpenXR SDK 1.1.49

OpenXR SDK 1.1.49 (2025-06-10)

This release primarily adds new extensions: a collection of ratified
multi-vendor extensions related to "spatial entities", multi-vendor extensions
to work with interaction render models, and a vendor extension.

• SDK
  • Improvement: Fix multiple clang-format formatting issues.
    (internal MR 3845)
  • Validation Layer: Add support for handles created by async operations.
    (internal MR 3030)
• Registry
  • New ratified multi-vendor extension: XR_EXT_spatial_entity
    (internal MR 3030,
    internal MR 3874)
  • New ratified multi-vendor extension: XR_EXT_spatial_anchor
    (internal MR 3286,
    internal MR 3874)

OpenXR SDK 1.1.48

OpenXR SDK 1.1.48 (2025-06-03)

This release makes a switch to 16KB page sizes for Android, to improve
compatibility of the loader binaries, among other build system adjustments. The
"gfxwrapper" utility used by hello_xr (and the CTS) now uses the widely-used
"GLAD2" wrapper to load OpenGL and related functionality, rather than internal
hand-coded wrappers.

• SDK
  • Improvement: Adapt gfxwrapper to use GLAD2 to load OpenGL, OpenGL ES, and EGL functions.
    (internal MR 3125,
    internal MR 3126)
  • Improvement: Minor loader_test debugging improvements.
    (internal MR 3836)
  • Improvement: Correctly detect availability of OpenGL on less common Windows
    platform variants, to fix 32-bit ARM non-UWP builds.
    (internal MR 3838)
  • Improvement: hello_xr: Warning fixes.
    (OpenXR-SDK-Source PR 516)
  • Improvement: Enable 16KB page sizes when building for Android, required for
    targeting Android 15+.
    (OpenXR-SDK-Source PR 548,
    OpenXR-SDK-Source issue 546)
• Registry
  • Change: Increment the revision of XR_BD_spatial_anchor_sharing.
    (internal MR 3855)
  • Chore: Reserve extension numbers.
    (internal MR 3696,
    internal MR 3797,
    internal MR 3815,
    internal MR 3827)
  • Fix: Explicitly list the "x" and "y" thumbstick components on
    "pico_g3_controller" in the XML.
    (internal MR 3851)
  • Increment graphics binding extension revision numbers due to
    rephrase/reorganization.
    (internal MR 3028,
    internal MR 3742)
  • New vendor extension: XR_META_simultaneous_hands_and_controllers
    (internal MR 2755)
  • New vendor extension: XR_META_body_tracking_full_body
    (internal MR 2961)
  • New vendor extension: XR_BD_future_progress
    (internal MR 3724)
