Vulkan SDK 1.4.363.0 Release Notes
Version 1.4.363.0 for Windows
September 29, 2026
Overview of new features in SDK 1.4.363.0
This SDK supports Vulkan API revision 1.4.363.
Deprecation Notices
- SDK Version Lifetime. Vulkan SDK's older than 2 years are removed from the Vulkan SDK download site and won't be available once removed. All SDK's are backwards compatible and using the latest or newer SDK is recommended due to ongoing bug fixes and enhancements in the SDK content.
Overview of new features in SDK 1.4.363.0
The Vulkan headers now include the following new extensions. Note that extensions are optional and may not be implemented by the underlying driver/ICD. Applications can now query for the presence of these new features.
- VK_INTEL_device_info
- VK_KHR_pipeline_library_group_handles
- VK_VALVE_buffer_device_address_allocation_alignment
- VK_NV_private_data_base_handle
- VK_EXT_cooperative_matrix_maintenance1
- VK_EXT_image_tiling_control
A new vkprofiles executable is integrated in the SDK. This executable is a command line tool to process Vulkan profiles files, generate code and documentation.
- In the next SDK, the gen_profiles scripts will be removed because the vkprofiles executable provides all the necessary functionality and supersedes them.
Improved validation coverage. VUID validation coverage documentation (validation_usage_todo.html) has been updated to represent the validation layer VUID coverage status.
Drivers: It is recommended you update Vulkan-capable hardware drivers to the latest recommended version from the hardware vendor. A list of Known Issues appears at the end of this document with more information.

Submitting Issues
If while using the tools and layers included in the SDK you find a defect in that tool or layer, the most expedient way to get a resolution is to submit to its corresponding repository. For example, if you believe you have found a defect in the Validation Layers, submit an issue at the repository for Validation Layers. The only exception to this is for the shader tool chain (glslang, SPIRV-Cross, SPIRV-Tools, shaderc). For these repositories you can submit issues against the SDK at vulkan.lunarg.com.
Known Issues
No Warning with Profiles Use: When using Vulkan Profiles requiring Profiles with the Vulkan Profiles layer, no warning is emitted when trying to override a device capability to a value that is not supported by the device.
Vulkan Configurator known issues are documented in the Vulkan Configurator Change Log
