Vulkan 1.1.94 was released today. According to Phoronix, this latest release of the graphics and compute API includes two new extensions: VK_KHR_swapchain_mutable_format, which allows the windowing system to use different formats of swap chain images, and VK_EXT_fragment_density_map, which lets you specify areas of the render target where the shader can be invoked few times, so you can reduce rendering quality in areas of the screen that are less important. For more details, see Vulkan-Docs.

Linux 4.20-rc4 is out. Of this week's release, Linus says "Nothing looks particularly odd or scary, although we do have some known stuff still pending. For example, the STIBP fixes are still being discussed and fine-tuned and haven't been merged yet. And there's a few mm fixes being talked about. Nothing that should keep people from testing the 4.20 rc's, though, so go out and test."
