OpenXR Specification 1.0.33

OpenXR Specification 1.0.33 (2024-01-03)

This release primarily adds new ratified functionality to the specification
describing the loader interaction with runtimes and API layers. This
functionality was previously described in non-normative text in the loader
design document, but was universally adopted for compatibility. It is now part
of the normative, ratified core specification. This change only affects vendors
of runtimes and API layers as well as contributors to the OpenXR loader:
applications do not directly use this API, the loader uses it on their behalf. A
number of other small fixes are also included.

• Registry
  • Extension reservation: Update author ID and reserve extensions for Varjo.
    (internal MR 3083)
  • Extension reservation: Reserve 10 extension ids each for ANDROIDX &
    ANDROIDSYS.
    (internal MR 3086)
  • Khronos ratified addition: Specify the existing loader negotiation functions
    (without modification) in the XML, moving from loader_interfaces.h to a new
    generated header openxr_loader_negotiation.h.
    (internal MR 2807,
    internal issue 1953)
  • XR_KHR_android_thread_settings: Fix the description of
    XrAndroidThreadTypeKHR enum values - they were swapped relative to their
    implicit meaning from their name.
    (internal MR 3077)
  • XR_MNDX_egl_enable: Update version to 2 to reflect function pointer type
    change released in 1.0.29.
    (OpenXR-Docs PR 159)
• Specification
  • Khronos ratified specification addition: move loader negotiation functions into
    the specification proper (from the loader design doc), moving corresponding
    functions from loader_interfaces.h to openxr_loader_negotiation.h. (The
    exact ratified core specification text is 1.0.29 with these changes added,
    available internally. Non-substantive core specification updates/fixes have
    occurred since then.)
    (internal MR 2807,
    internal issue 1953,
    internal MR 3101)
  • Scripts: Adjust Makefile so we now error on any checkSpecLinks warning when
    running that target.
    (internal MR 3072)
  • XR_HTC_anchor: Fix parameter name error in prose description.
    (internal MR 3072)
  • XR_KHR_android_thread_settings: Fix the description of
    XrAndroidThreadTypeKHR enum values - they were swapped relative to their
    implicit meaning from their name.
    (internal MR 3077)
  • XR_MNDX_egl_enable: Update revision info and version to 2 to reflect function
    pointer type change released in 1.0.29.
    (OpenXR-Docs PR 159)
  • loader design doc: Fix minor typos.
    (internal MR 3065,
    internal MR 3103)
• Misc
  • Update/correct names.
  • Ship a .mailmap file in the public repositories, maintained separately
    from the larger one used in the private monorepo, to correct names/emails
    and unify contributor identities.
  • Update Khronos Group copyright dates.

OpenXR Specification 1.0.32

OpenXR Specification 1.0.32 (2023-11-29)

This release contains a number of vendor extensions, plus a new ratified
revision to the XR_KHR_loader_init extension that specifies forwarding the
init calls to API layers. Vendors of API layers, primarily on Android, must
verify they can handle being passed XR_NULL_HANDLE for the instance parameter
of xrGetInstanceProcAddr, to avoid bugs when using the updated loader. This
release also features the remaining "checkSpecLinks" consistency warning fixes
in the manually-written specification text in extensions.

• Registry
  • XR_KHR_loader_init: New Khronos ratified revision, adds support for
    forwarding loader init calls to API layers
    (internal MR 2703)

• Specification
  • XR_KHR_loader_init: New Khronos ratified revision, now additionally specifies
    forwarding loader init calls to API layers
    (internal MR 2703)
  • Fix "checkSpecLinks" warnings about member and parameter references in
    extensions to the specification. This has changed the documentation of a number
    of structures and functions across several extensions, although the C
    prototypes/definitions in the spec as well as the header file contents have
    stayed constant.

OpenXR Specification 1.0.31

OpenXR Specification 1.0.31 (2023-10-18)

This release features two new vendor extensions, some XML revisions to other
vendor extensions, and a substantial amount of fixes to the prose of the core
specification and some extensions. All specially-formatted mentions of a
parameter or field name (that is, names marked up with the pname macro in the
AsciiDoctor source) are now being checked by a script to be sure they are known.
With the fixes in this release, nearly all such name mentions now either (1)
match the function or structure in whose description they are mentioned, or (2)
have been qualified with the function or structure to which they do belong.
Misspellings, missing fields/parameters, and extraneous parameters have been
fixed as well. (Some fixes of this type to vendor extensions are still pending
and will be in an upcoming patch release.) While this has changed the prose, it
has not resulted in substantive changes to the XML, and therefore the code
snippets in the specification as well as the header files remain accurate and
unaffected by these fixes.
