Vulkan SDK 1.0.46 Release Notes

This SDK supports Vulkan API revision 1.0.46. The prior SDK supported Vulkan API revision 1.0.42.
Drivers: LunarG recommends that you update your Vulkan-capable hardware drivers to the latest recommended version from your hardware vendor. A list of Known Driver Issues appears at the end of this document with more information.
SDK Libraries have moved -- As of the 1.0.42 SDK, the SDK library files were moved out of /bin into /lib for 64-bit libraries and /lib32 for 32-bit libraries. This will require you to update your project files to point to the proper location if you are updating from an older SDK. The change was performed to avoid 32-bit compatibility issues.
Overview of new features in SDK 1.0.46

Update loader and docs to Vulkan version 1.0.46.
Extensions introduced since the 1.0.42 SDK include:
- VK_GOOGLE_display_timing (added in the Vulkan 1.0.43 spec)
- VK_EXT_hdr_metadata (added in the Vulkan 1.0.43 spec)
- VK_EXT_swapchain_colorspace (added in the Vulkan 1.0.45 spec)
- VK_KHR_incremental_present (added in the Vulkan 1.0.46 spec)
Vulkan Layers have changed:
- In this release, the validation layers have been updated to operate correctly with all non-experimental extensions up to and including those newly added to the 1.0.46 header.
- Image layout and other image-related validation has been streamlined and coverage has been increased.
- Layers have improved device feature and limit validation coverage
VkTrace/VkReplay additions:
- vktraceviewer included in both the Windows and Linux SDKs and is an alpha release.
- vktrace trim feature is now available and has been improved. Trim can be used to specify a frame interval to capture - all other frames are removed from the trace file, resulting in a smaller trace file.
- vktrace has been improved to increase portability of generated trace files across display driver versions.
Scores of bugfixes, validation coverage and accuracy improvements, and many feature additions

Important Note About Experimental Extensions The KHX and NVX identifiers in the name indicate that the extension is experimental, and is being considered for future standardization. In the case of a KHX extension, this extension is being considered as either a KHR extension or core Vulkan API functionality. NVX extensions are being considered for either a final NV or a more general (EXT, KHR) extension.
As experimental extensions:

Developers are encouraged to experiment with them and provide feedback, but should not use them as the basis for production applications.
These experimental extensions are expected to be supported for a limited time only.
They may change their interfaces and behavior in significant ways as a result of feedback
They may be withdrawn or replaced with a different stable (KHR, EXT, ...) extension or core functionality at any time.
Implementations of these extensions receive limited or no testing when submitted to the Khronos conformance process.
Using experimental extensions with the validation layers may produce inaccurate validation results.
