VULKAN --
The Khronos Group has done a Friday evening update to the Vulkan 1.0 API specification.

Vulkan 1.0.43 includes a number of GitHub and internal-Khronos issues around document clarifications and other minor behavior differences.

Arguably most exciting about Vulkan 1.0.43 are two new extensions and they include VK_EXT_hdr_metadata and VK_GOOGLE_display_timing.

VK_EXT_hdr_metadata is largely the renaming of the existing VK_EXT_SMPTE2086_metadata extension. As a reminder, this extension is about supporting SMPTE 2086 meta-data in the swap chain. This new VK_EXT_hdr_metadata extension further advances the SMPTE meta-data to also include the CTA (Consumer Technology Association) 861.3 meta-data support too. This is all about improving Vulkan's HDR support although for most users it won't mean much until HDR displays are more common and for Linux users when High Dynamic Range is better supported by the Linux desktop.

VK_GOOGLE_display_timing is a new extension to allow applications making use of VK_KHR_swapchain to obtain information about the presentation engine's display, such as timing information.

The latest Vulkan specifications are available from the Khronos.org registry.
