OpenXR SDK 1.1.54 (2025-12-02)

This release updates the C++ standards version used by the package, and includes changes to hello_xr to bring it closer in line with the OpenXR-CTS (which come from a shared codebase) and allow optional submission of depth textures where supported, among other changes.

• Improvement: Add description for XR_SPACE_COMPONENT_TYPE_TRIANGLE_MESH_META. (internal MR 4070)
• Schematron: Add validation to ensure bitmasks are non-plural before Flags/FlagBits. (internal MR 2678)
