VULKAN --
The Khronos Group is ending out March by releasing Vulkan 1.0.46.

The Vulkan 1.0.46 change-log is pretty boring in just mentioning a handful of fixes. But there is a new Vulkan extension that was quietly added: VK_KHR_incremental_present.

Explained by the new documentation about VK_KHR_incremental_present, "This device extension extends slink:vkQueuePresentKHR, from the VK_KHR_swapchain extension, allowing an application to specify a list of rectangular, modified regions of each image to present. This should be used in situations where an application is only changing a small portion of the presentable images within a swapchain, since it enables the presentation engine to avoid wasting time presenting parts of the surface that haven't changed."

Basically if an application is doing damage tracking with most of the image being unchanged, VK_KHR_incremental_present is an efficient way to only update portions of the screen. Work on VK_KHR_incremental_present was led by Google.

Vulkan 1.0.46 can be fetched from the Git repository.
