    Appendix D: Core Revisions (Informative)

    New minor versions of the Vulkan API are defined periodically by the Khronos Vulkan Working Group. These consist of some amount of additional functionality added to the core API, potentially including both new functionality and functionality promoted from extensions.

    It is possible to build the specification for earlier versions, but to aid readability of the latest versions, this appendix gives an overview of the changes as compared to earlier versions.

    Version 1.3

    Vulkan Version 1.3 promoted a number of key extensions into the core API:

    All differences in behavior between these extensions and the corresponding Vulkan 1.3 functionality are summarized below.

    Differences relative to VK_EXT_4444_formats

    If the VK_EXT_4444_formats extension is not supported, support for all formats defined by it are optional in Vulkan 1.3. There are no members in the VkPhysicalDeviceVulkan13Features structure corresponding to the VkPhysicalDevice4444FormatsFeaturesEXT structure.

    Differences relative to VK_EXT_extended_dynamic_state

    All dynamic state enumerants and entry points defined by VK_EXT_extended_dynamic_state are required in Vulkan 1.3. There are no members in the VkPhysicalDeviceVulkan13Features structure corresponding to the VkPhysicalDeviceExtendedDynamicStateFeaturesEXT structure.

    Differences relative to VK_EXT_extended_dynamic_state2

    The optional dynamic state enumerants and entry points defined by VK_EXT_extended_dynamic_state2 for patch control points and logic op are not promoted in Vulkan 1.3. There are no members in the VkPhysicalDeviceVulkan13Features structure corresponding to the VkPhysicalDeviceExtendedDynamicState2FeaturesEXT structure.

    Differences relative to VK_EXT_texel_buffer_alignment

    The more specific alignment requirements defined by VkPhysicalDeviceTexelBufferAlignmentProperties are required in Vulkan 1.3. There are no members in the VkPhysicalDeviceVulkan13Features structure corresponding to the VkPhysicalDeviceTexelBufferAlignmentFeaturesEXT structure. The texelBufferAlignment feature is enabled if using a Vulkan 1.3 instance.

    Differences relative to VK_EXT_texture_compression_astc_hdr

    If the VK_EXT_texture_compression_astc_hdr extension is not supported, support for all formats defined by it are optional in Vulkan 1.3. The textureCompressionASTC_HDR member of VkPhysicalDeviceVulkan13Features indicates whether a Vulkan 1.3 implementation supports these formats.

    Differences relative to VK_EXT_ycbcr_2plane_444_formats

    If the VK_EXT_ycbcr_2plane_444_formats extension is not supported, support for all formats defined by it are optional in Vulkan 1.3. There are no members in the VkPhysicalDeviceVulkan13Features structure corresponding to the VkPhysicalDeviceYcbcr2Plane444FormatsFeaturesEXT structure.
