The new features are as follows: * A limit on the maximum number of descriptors that are supported in a single descriptor set layout. Some implementations have a limit on the total size of descriptors in a set, which cannot be expressed in terms of the limits in Vulkan 1.0. * A limit on the maximum size of a single memory allocation. Some platforms have kernel interfaces that limit the maximum size of an allocation. === New Object Types None. === New Enum Constants * Extending elink:VkStructureType: ** ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_MAINTENANCE_3_PROPERTIES_KHR ** ename:VK_STRUCTURE_TYPE_DESCRIPTOR_SET_LAYOUT_SUPPORT_KHR === New Enums None. === New Structures * slink:VkPhysicalDeviceMaintenance3PropertiesKHR * slink:VkDescriptorSetLayoutSupportKHR === New Functions * flink:vkGetDescriptorSetLayoutSupportKHR === Promotion to Vulkan 1.1 All functionality in this extension is included in core Vulkan 1.1, with the KHR suffix omitted. The original type, enum and command names are still available as aliases of the core functionality. === Issues None. === Version History * Revision 1, 2017-08-22
