Change log for September 19, 2018 Vulkan 1.1.85 spec update: * Update release number to 85. Public Issues: * Add self-dependency ename:VK_DEPENDENCY_BY_REGION_BIT valid usage statements for slink:VkSubpassDependency(public pull request 778). * Apply fix from pull request 742 to slink:VkSubpassDependency and slink:VkSubpassDependency2 (public pull request 779). * Specify the units of slink:VkBufferImageCopy::pname:bufferRowLength and pname:bufferImageHeight as texels (public pull request 781). * Better specify promoted parameter mapping in the `<<VK_KHR_create_renderpass2>>` appendix (public pull request 782). Internal Issues: * Only include the <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>> section in Vulkan 1.1 or later (internal issue 1381). Other Issues: * Clean up redundant valid usage language for the `VK_ANDROID_external_memory_android_hardware_buffer` extension interaction with slink:VkImageCreateInfo. * Fix error in a flag name within valid usage statements for slink:VkMemoryAllocateInfo. * Clarify that memory types are not totally ordered in slink:VkPhysicalDeviceMemoryProperties. * For slink:VkWriteDescriptorSetInlineUniformBlockEXT, set structextends="VkWriteDescriptorSet" in `vk.xml`, and make slink:VkDescriptorSetLayoutBindingFlagsCreateInfoEXT::pname:pBindingFlags optional. * Add documentation of 'provisional' XML attribute to registry.txt. New Extensions: * `VK_NV_compute_shader_derivatives` * `VK_NV_corner_sampled_image` * `VK_NV_fragment_shader_barycentric` * `VK_NV_mesh_shader` * `VK_NV_representative_fragment_test` * `VK_NV_scissor_exclusive` * `VK_NV_shader_image_footprint` * `VK_NV_shading_rate_image` * `VK_NVX_raytracing`

Change log for November 4, 2018 Vulkan 1.1.91 spec update: * Update release number to 91. Public Issues: * Update Ubuntu subsystem build instructions in `BUILD.adoc` (public pull request 624). * Delete the `VK_KHR_mir_surface` extension from the Specification and XML, due to EOL of the only driver known to have supported it, and near-EOL of Mir itself (public issue 814). * Fix options for some figures that were using old ones (public pull request 841). * Fix various accidentally repeated words (public pull request 843). * Use `time.process_time()`, introduced in Python 3.3, in the scripts instead of `time.clock()`, which will be removed in Python 3.8 (public pull request 844). Internal Issues: * Update valid usage statements for `VK_ANDROID_external_memory_android_hardware_buffer` in slink:VkMemoryAllocateInfo, slink:VkImportAndroidHardwareBufferInfoANDROID, and flink:vkGetAndroidHardwareBufferPropertiesANDROID to actually be verifiable (internal issue 1419). * Update valid usage statements for `VK_ANDROID_external_memory_android_hardware_buffer` in slink:VkMemoryAllocateInfo, slink:VkImageCreateInfo, and slink:VkImageViewCreateInfo to move valid usage statements in doubly-nested bullet points up one level, accomodating limitations of the valid usage extraction script that creates `validusage.json` (internal issue 1434). * Fix typo etext:VK_ACCESS_SHADING_RATE_IMAGE_BIT_NV to the correct ename:VK_ACCESS_SHADING_RATE_IMAGE_READ_BIT_NV. * Add missing etext:VK_STRUCTURE_TYPE_* tokens to appendices for extensions missing them. New Extensions: * `VK_AMD_memory_overallocation_behavior` * `VK_NV_ray_tracing`, replacing `VK_NVX_raytracing`

Change log for April 16, 2019 Vulkan 1.1.107 spec update: * Update release number to 107. Public Issues: * Fix revision date for the `<<VK_AMD_gpu_shader_half_float>>` appendix (public issue 617). * Make <<synchronization-pipeline-barriers-subpass-self-dependencies, subpass self-dependencies>> less restrictive (public issue 777). * Fix the `<<VK_EXT_full_screen_exclusive>>` dependency on `<<VK_KHR_win32_surface>>` in `vk.xml` (public pull request 849). * Remove single-page (`apispec.html`) refpage sub-targets from the Makefile `allman` target and the build instructions. The target is still present in the Makefile, but we have not been actively maintaining the single-page document and do not promise it will work. The full Specification and the individual API reference pages are what we support and publish at present (public issue 949). Internal Issues: * De-duplicate common valid usage statements shared by multiple commands or structures by using asciidoctor includes and dynamically assigning part of the valid usage ID based on which command or structure they're being applied to (internal issue 779). * Add reference pages for constructs not part of the formal API, such as platform calling convention macros, and script changes supporting them This required suppressing some check_spec_links warning classes in order to pass CI, until a more sophisticated fix can be done (internal issue 888). * Change math notation for the elink:VkPrimitiveTopology descriptions to use short forms `v` and `p` instead of `vertex` and `primitive`, increasing legibility (internal issue 1611). * Rewrite generated file includes relative to a globally specified path, fixing some issues with refpage generation (internal issue 1630). * Update contributor list for `<<VK_EXT_calibrated_timestamps>>`. * Fix use of pathlin in `scripts/generator.py` so the script will work on Windows under Python 3.5 (internal merge request 3107). * Add missing conditionals around the <<descriptorsets-accelerationstructure, Acceleration Structure>> section (internal merge request 3108). * More script synchronization with OpenXR spec repository (internal merge request 3109). * Mark the `<<VK_AMD_gpu_shader_half_float>>` and `<<VK_AMD_gpu_shader_int16>>` extensions as deprecated in `vk.xml` and the corresponding extension appendices (internal merge request 3112). New Extensions: * `<<VK_EXT_headless_surface>>`
