Changelog for OpenXR-SDK-Source and OpenXR-SDK Repo

Update log for the OpenXR-SDK-Source and OpenXR-SDK repo on GitHub. Updates are in reverse chronological order starting with the latest public release.

Note that only changes relating to the loader and some of the build changes will affect the OpenXR-SDK repository.

This summarizes the periodic public updates, not individual commits. Updates on GitHub are generally done as single large patches at the release point, collecting together the resolution of many Khronos internal issues, along with any public pull requests that have been accepted. In this repository in particular, since it is primarily software, pull requests may be integrated as they are accepted even between periodic updates.

OpenXR SDK 1.0.22 (2022-01-12)

This release features a number of new extensions, as well as some software updates and fixes, especially for Android. If you are using the bundled jsoncpp, this is also a security release as the bundled jsoncpp was upgraded to incorporate security improvements from upstream.

OpenXR SDK 1.0.21 (2022-01-10)

This release was withdrawn due to a typo noticed after initial publication. All changes are now listed under 1.0.22.

OpenXR SDK 1.0.20 (2021-10-04)

This release includes a proposed cross-vendor OpenXR loader for Android, Android build system for hello_xr, and a number of new vendor extensions.

OpenXR SDK 1.0.19 (2021-08-24)

This release features a number of new or updated vendor extensions, as well as some minor cleanups and bug fixes in the SDK.

OpenXR SDK 1.0.18 (2021-07-30)

This release mostly adds new extensions. It also includes some fixes to the included layers, as well as text in the loader documentation describing how runtimes can register themselves for manual selection. This is not used by the loader itself and does not require any changes to the loader, but it may be useful to developer-focused supporting software.

  • Registry
    • Add ratified XR_KHR_swapchain_usage_input_attachment_bit Khronos extension. (Promotion of XR_MND_swapchain_usage_input_attachment_bit, which is now deprecated.) (internal MR 2045)
    • Add new XR_FB_foveation, XR_FB_foveation_configuration, and XR_FB_foveation_vulkan vendor extensions. (internal MR 2050)
    • Add additional extension dependencies to XR_FB_swapchain_update_state. (internal MR 2072, internal issue 1572)
    • Add new XR_FB_composition_layer_secure_content vendor extension. (internal MR 2075)
    • Add new XR_FB_composition_layer_alpha_blend vendor extension. (internal MR 2078)
    • Add new XR_FB_composition_layer_image_layout vendor extension. (internal MR 2090)
    • Add new XR_MSFT_spatial_anchor_persistence vendor extension. (internal MR 2093)
    • Add some simple Schematron rules and a script to check the XML registry against them. (internal MR 2103)
    • Register author ID and Reserve vendor extensions for Unity. (internal MR 2105)
    • Reserve extension ID range 187-196 for LIV Inc. (internal MR 2102)
  • SDK
    • Describe how runtimes may register themselves at installation time for manual selection. (internal MR 2081, internal MR 2109, internal issue 1574)
    • Include sRGB in list of supported swapchain texture formats for the HelloXR OpenGLES plugin. (internal MR 2066)
    • layers: Refactor generated xrGetInstanceProcAddr implementations to avoid deeply-nested if ... else blocks. (Some compilers have limits we were nearing or hitting.) (internal MR 2050)
    • validation layer: Set default logging mode to stdout ("text") instead of none. (OpenXR-SDK-Source PR 262)
    • validation layer: Fix invalid struct type error message to show the expected type instead of the actual type. (OpenXR-SDK-Source PR 263)

OpenXR SDK 1.0.17 (2021-06-08)

This release features an important fix to the loader for an invalid-iterator bug introduced in 1.0.16. All developers shipping the loader are strongly encouraged to upgrade. It also includes a variety of new vendor extensions.

OpenXR SDK 1.0.16 (2021-05-11)

This release contains an update to define a new error code, XR_ERROR_RUNTIME_UNAVAILABLE, now returned by the loader at xrCreateInstance and xrEnumerateInstanceProperties when it cannot find or load a runtime for some reason. This should be more clear for developers when encountering it, as well as helpful when troubleshooting errors hit by users. (The previously-returned error was typically XR_ERROR_INSTANCE_LOST, which is confusing when returned when trying to create an instance.) This release also includes a new multi-vendor extension, a new vendor extension, and improved concurrency handling in the loader, among smaller fixes.

OpenXR SDK 1.0.15 (2021-04-13)

The main SDK change in this release is that the OpenXR headers no longer expose extension function prototypes because extension functions are not exported by the loader. This should prevent some confusion during development without affecting code that correctly compiles and links with older SDKs. Code that was compiled but not linked (for instance, the automated tests of example source in the specification) and that would not have successfully linked may have their defects highlighted by this change, however. If you need those prototypes still available, there is a preprocessor define that can re-enable them. The function pointer definitions are always available.

In addition to that header change, this release contains three new vendor extensions plus an assortment of SDK fixes.

OpenXR SDK 1.0.14 (2021-01-27)

This release contains a collection of fixes and improvements, including one new vendor extension. Notably, we have relicensed all files that become part of the loader, so the loader may be "Apache-2.0 OR MIT" for downstream license compatibility.

OpenXR SDK 1.0.13 (2020-11-24)

The SDK in this release features some fixes to the loader's layer parsing: upgrading is recommended. The hello_xr example has also been improved. The registry for this release features a new ratified Khronos extension which will serve as the basis of other extensions, as well as a number of new vendor extensions.

OpenXR SDK 1.0.12 (2020-09-25)

This release features a number of new ratified KHR extensions, as well as a new vendor extension.

OpenXR SDK 1.0.11 (2020-08-14)

This release is mainly for SDK improvements, with only small changes to the docs. A new error code is provided for xrCreateSession for developers convenience.

  • Registry
  • SDK
    • Improve language usage in code and comments to be more respectful. (internal MR 1881)
    • Loader: Correct type of "extension_version" in API layer manifest files to string, while maintaining backwards compatibility. Remove undocumented and unused "device_extensions" and "entrypoints" keys. (internal MR 1867, internal issue 1411)
    • Replace usage of std::filesystem::canonical with PathCchCanonicalize on Windows platform to work around bug on UWP platforms. This also replaces PathCanonicalize with PathCchCanonicalize and adds the appropriate library for linking in. (OpenXR-SDK-Source/#198)
    • Support for building more projects when targeting UWP, and support for all architectures when targeting Win32. (OpenXR-SDK-Source/#199)
    • hello_xr: fix Vulkan image layout transitions. (internal MR 1876)
    • validation: Enable three additional checks (on optional arrays with non- optional counts) that were missing because of a script error. (internal MR 1881)

OpenXR SDK 1.0.10 (2020-07-28)

Note the relicensing of the registry XML file and some include files provided by or generated by this repository (first item in each changelog section). Each file's header, or an adjacent file with .license appended to the filename, is the best reference for its license terms. We are currently working on ensuring all files have an SPDX license identifier tag either in them or in an adjacent file. This is still in progress but mostly complete.

  • Registry
    • Relicense registry XML from MIT-like "Khronos Free Use License for Software and Documentation" to, at your option, either the Apache License, Version 2.0, found at, or the MIT License, found at, for broader license compatibility with downstream projects.

    • scripts: Teach xml-consistency to handle bitmask values defined in extensions. (internal MR 1865)
  • SDK
    • Relicense generated headers openxr.h, openxr_platform.h, openxr_reflection.h, and static header openxr_platform_defines.h from the Apache License, version 2.0, to, at your option, either the Apache License, Version 2.0, found at, or the MIT License, found at, for broader license compatibility with downstream projects.

OpenXR SDK 1.0.9 (2020-05-29)

OpenXR SDK 1.0.8 (2020-03-27)

Patch release for the 1.0 series.

  • Registry
  • SDK
    • Add SPDX license identifier tags to nearly all (code) files, including generated files. (internal MR 1686)
    • Fix build system behavior with MSVC building in Release mode: only attempt to copy PDB files if they exist. (internal MR 1701)

OpenXR SDK 1.0.7 (2020-03-20)

Patch release for the 1.0 series.

Note: Changelogs are now being assembled with the help of the Proclamation tool, so the format has changed somewhat.

  • Registry
    • Introduce XR_MSFT_hand_interaction extension for hand interaction profile. (internal MR 1601)
    • Introduce XR_EPIC_view_configuration_fov extension for system field-of-view queries. (internal MR 1170)

OpenXR 1.0.6 release (24-January-2020)

Patch release for the 1.0 series.

This release contains, among other things, a substantial simplification and cleanup of the loader, which should fix a number of issues and also make it forward compatible with extensions newer than the loader itself. As a part of this change, the loader itself now only supports a single XrInstance active at a time per process. If you attempt to create a new instance while an existing one remains (such as in the case of application code leaking an XrInstance handle), the loader will now return XR_ERROR_LIMIT_REACHED.
