Vulkan Specification 1.2 released

Almost entirely developer focused. So us gamers won't see much of a difference. BUT its easier for developers, better optimization, visual quality, and since it's easier to use, LESS BUGS!
Perfect time for a new API update. As mentioned in the article, Windows 7 is now EOL. Windows 8 is similar to 10(less platform-specific code). Next-Gen consoles are shipping soon, which means API development will be at a very high level as programmers need to acclimate with the market changes.
I do wonder if PS will use a custom Vulkan instead of their own proprietary API. It could really ease the load on Devs, make games cheaper, etc.
Main reason to get excited though, Kronos Group have fully implemented NATIVE SUPPORT for HLSL from MS's D3D. It compiles it down to SPIR-V, which lets it work with Vulkan.
AKA this means expect more Linux Support. Since Developers now have native access they can have a much (x100) easier time porting and getting Windows games on Linux. Wine Windows Compatibility, Valve's Proton tool and DXVK are supported.
