Change log for June 24, 2017 Vulkan 1.0.53 spec update: * Bump API patch number and header version number to 53 for this update. Github Issues: Internal Issues: * Clarify mappings of coordinates for mutable, compatible image views in slink:VkImageViewCreateInfo (internal issue 815). * Make ename:VK_BIND_SFR_BIT require a logical device with multiple physical devices, so that standard sparse image block dimensions are only required on systems that support multi-GPU (internal issue 835). * Convert all files from use of // refBegin .. // refEnd comments to delimit ref pages, to use of open blocks, and update style guide accordingly (internal issue 839). * Add valid usage for slink:VkWriteDescriptorSet when performing updates to a ename:VK_STORAGE_IMAGE descriptor with layout ename:VK_IMAGE_LAYOUT_GENERAL. * Add a hack to the validity generator script to support an odd interaction between flink:vkCmdFillBuffer and an extension (internal issue 853). * Remove redundant text describing slink:VkBufferCreateInfo::pname:usage, which was already covered by implicit valid usage (internal issue 854). * Update implicit validity generator script to properly handle the pname:sType and pname:pNext members of "returnedonly" structures (internal issue 874). * Note that slink:VkApplicationInfo::pname:pApplicationName & slink:VkApplicationInfo::pname:pEngineName are optional, and add missing implicit valid usage statements for flink:vkDestroyInstance. * Added missing valid usage for flink:vkCmdWriteTimestamp to require a timestamp query pool. * Simplify and/or split "`non-atomic`" valid usage statements. New Extensions: * `VK_AMD_gpu_shader_int16` * `VK_EXT_blend_operation_advanced` * `VK_EXT_sampler_filter_minmax` * `VK_NV_framebuffer_mixed_samples` ----------------------------------------------------- Note: the 1.0.52 spec wasn't published on github, so the 1.0.53 release combines both change sets. ----------------------------------------------------- Change log for June 13, 2017 Vulkan 1.0.52 spec update: * Bump API patch number and header version number to 52 for this update. Github Issues: Internal Issues: * Clarify behavior when non-coherent memory has <<memory-device-unmap-does-not-flush, not been flushed before being unmapped>> (internal issue 819). * Fix description of code:WorkgroupSize builtin to note it decorates an object, not a variable (internal issue 836). * Fix asciidoc attributes so that trailing '{plus}' symbols in [eq] style equations are rendered properly (internal issue 845). * Add language to the "`Extension Handles, Objects, Enums, and Typedefs`" section of the Procedures and Conventions document stating that any new handle type requires a corresponding entry in the elink:VkObjectType enumerated type (internal issue 856). * Update style guide to use slink macro for Vulkan handle type names, and define narrow conditions under which to use the *name and *text macros instead of *link (internal issue 886). * Add a dependency of the <<VK_KHX_device_group,VK_KHX_device_group>> extension on VK_KHX_device_group_creation to +vk.xml+ and the extension appendix. * Change the copyright on Vulkan specification asciidoc *source* files to CC-BY 4.0, and update the proprietary Khronos copyright applied to the generated *output* formats (internal issue 327). This enables broader re-use and modification of the Vulkan specification sources, while not affecting the Reciprocal IP License between Vulkan Adopters and Working Group Members. New Extensions: * `VK_NV_fill_rectangle` * `VK_NV_fragment_coverage_to_color`

Change log for September 30, 2016 Vulkan 1.0.29 spec update: * Bump API patch number and header version number to 29 for this update. Github Issues: * Remove redundant constraint on slink:VkCommandBufferInheritanceInfo::pname:queryFlags (public issue 224). * Fix typo and remove link in Note in the <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> section (public issue 359). * Fix erroneous validation statement for the pname:layout member of slink:VkComputePipelineCreateInfo (public issue 362). Internal Issues: * Restore long figure captions using asciidoc sidebar blocks, due to restrictions of asciidoc syntax (internal issue 101). * Replace most latexmath equations with comparable markup in straight asciidoc, which significantly improves time required to fully load and process the HTML forms of the Specification. There are known minor font and alignment inconsistencies with MathJax and PDF rendering of latexmath equations. Please do not file github issues about these. We are aware of the inconsistencies and will make refinements over time, while the performance improvements are compelling in at least some major browsers (internal issue 313). * Move handcoded validity statements from +vk.xml+ into the Specification body, easing work in the single-branch model. Specify the distinction between these explicit statements, and the implicit validity statements inferred from vk.xml. Validity statements now appear in two blocks for each command and structure - handcoded "Valid Usage" and the implicit "Valid Usage (Implicit)" (internal issue 392). * Add the +returnedonly="false"+ attribute to WSI output structures, removing incorrectly generated implicit validity statements for slink:VkDisplayPropertiesKHR, slink:VkDisplayPlanePropertiesKHR, slink:VkDisplayModePropertiesKHR, slink:VkDisplayPlaneCapabilitiesKHR, slink:VkSurfaceCapabilitiesKHR, and slink:VkSurfaceFormatKHR structures (internal issue 486). * Update slink:VkImageLayout to require the ename:VK_IMAGE_USAGE_SAMPLED_BIT be set for sampled depth/stencil images (internal issue 487). * Use an explicit format specifier string for the date command invocation in the +Makefile+ instead of the shorthand -R option, which doesn't work on BSD and MaxOS X date commands (internal issue 500). Other Issues: * Use the terms ``allocation scope'' and ``extension scope'' instead of just ``scope'', and add them to the glossary.

Blending combines the incoming _source_ fragment's R, G, B, and A values
with the _destination_ R, G, B, and A values of each sample stored in the
framebuffer at the fragment's [eq]#(x~f~,y~f~)# location.
Change log for November 25, 2018 Vulkan 1.1.94 spec update: * Update release number to 94. Public Issues: * Use the terms "`texel block`" and "`texel block size`" instead of "`data element`" and "`element size`", and define "`element`" as an array slot. In addition to the terminology changes, retitled the <<texel-block-size, Representation and Texel Block Size>> section and added texel block size / no. of texels/block information to the <<features-formats-compatibility, Compatible Formats>> table. There is some additional work underway to make sure the compatibility language makes sense for all of uncompressed, compressed, and multiplanar formats (public issue 763). * Cleanup `VK_NV_ray_tracing` language (public issues 858, 859). Internal Issues: * Specify in <<shaders-invocationgroups, Invocation and Derivative Groups>> and <<textures-output-format-conversion, Texel Output Format Conversion>> that derivative groups are quads when code:SubgroupSize >= 4 (internal issue 1390). * Make the type of slink:VkDescriptorUpdateTemplateCreateInfo::pNext `const` following pattern for the other stext:Vk*CreateInfo structures (internal issue 1459). * Specify that flink:vkCmdClearAttachments executes as a drawing command, rather than a transfer command (internal issue 1463). * Update `VK_NV_ray_tracing` to use code:InstanceId instead of code:InstanceIndex. New Extensions: * `VK_KHR_swapchain_mutable_format` * `VK_EXT_fragment_density_map`

Change log for September 23, 2016 Vulkan 1.0.28 spec update: * Bump API patch number and header version number to 28 for this update. Github Issues: * Minor spelling and typography cleanup, add definitions of ename:VK_FALSE and ename:VK_TRUE as just what their names say (public issues 220, 318, 325, 365; internal issues 451, 496) * Clarify that the pname:maxDescriptorSet limits in the <<features-limits-required,Required Limits>> table are n * maxPerStage limit (where n=number of supported stages) (public issue 254). * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific Macro Definitions>> appendix (public issue 314). * Add valid usage statement to slink:VkPipelineLayoutCreateInfo disallowing multiple push constant ranges for the same shader stage (public issue 340). * Clarify the elink:VkSharingMode description of what executing the "same" barriers means in case of ownership transfer (public issue 347). * Rename copyright.txt and add COPYING.md to try and reduce confusion about applicable copyrights (public issue 350). * Extend the table in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section to describe the external headers included when each etext:VK_USE_PLATFORM_* macro is defined (public issue 376). Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Change log for July 10, 2016 Vulkan 1.0.20 spec update: * Bump API patch number and header version number to 20 for this update. Github Issues: * Replaced existing reference pages by text automatically extracted from the specification source, or generated from vk.xml in some cases. This isn't a complete solution for the reference pages, but puts them in a much better state. The ref pages (only) are now placed under a CC BY open source license, which is more current than the obsolete license previously used. Further improvements to the pages should not edit them directly, but instead concentrate on the specification source from which the ref pages are being extracted (public issues 44, 55, 160; internal issue 389).

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.

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).

Change log for March 3, 2019 Vulkan 1.1.102 spec update: * Update release number to 102. Public Issues: * Simplify flink:vkGetImageMemoryRequirements constraint for ename:VK_MEMORY_PROPERTY_LAZILY_ALLOCATED_BIT (public pull request 817). * Fix typo in markup of the <<textures-texel-coordinate-systems-diagrams, Texel Coordinate Systems, Corner Sampling>> image that was generating complaints from chunked HTML output generation (public pull request 928). Internal Issues: * Split the old <<features, Features>> chapter into four chapters: <<features, Features>>, <<limits, Limits>>, <<formats, Formats>>, and <<capabilities, Capabilities>>, with minor edits to the introductory paragraph of each chapter. Anchor names in these chapters were changed, with corresponding effects to xrefs to these anchors elsewhere in spec markup . The purpose is to make the chunked HTML spec output load faster on what was previously a single, gigantic chapter (internal issue 1554). * Add ename:VK_PIPELINE_STAGE_RAY_TRACING_SHADER_BIT_NV, to the supported pipeline stages for ename:VK_ACCESS_UNIFORM_READ, ename:VK_ACCESS_SHADER_READ, and ename:VK_ACCESS_SHADER_WRITE in the <<synchronization-access-types-supported>> table. * Correct legal name of Google, LLC in vk.xml \<tags> section and a copyright statement. * Clarify that Vulkan treats the Android code:AHARDWAREBUFFER_FORMAT_R8G8B8X8_UNORM format as RGBA, and the application is responsible for forcing the X/A component to be read as 1.0, in the <<memory-external-android-hardware-buffer-formats>> table. * Clarify the vertex order of various primitive topologies, and define the order of transform feedback vertex capture based on that. This involves a lot of refactoring and cleanup in the <<drawing-primitive-topologies, Primitive Topologies>>, <<geometry-input, Geometry Shader Input Primitives>> sections, and <<vertexpostproc-transform-feedback Transform Feedback>> sections, and numerous places in the <<tessellation>> chapter, New Extensions: * `VK_EXT_metal_surface` * `VK_EXT_ycbcr_image_arrays` (internal issue 1361). * `VK_NVX_image_view_handle`

Change log for September 30, 2016 Vulkan 1.0.29 spec update: * Bump API patch number and header version number to 29 for this update.

Internal Issues: * Restore long figure captions using asciidoc sidebar blocks, due to restrictions of asciidoc syntax (internal issue 101). * Replace most latexmath equations with comparable markup in straight asciidoc, which significantly improves time required to fully load and process the HTML forms of the Specification. There are known minor font and alignment inconsistencies with MathJax and PDF rendering of latexmath equations. Please do not file github issues about these. We are aware of the inconsistencies and will make refinements over time, while the performance improvements are compelling in at least some major browsers (internal issue 313). * Move handcoded validity statements from +vk.xml+ into the Specification body, easing work in the single-branch model. Specify the distinction between these explicit statements, and the implicit validity statements inferred from vk.xml. Validity statements now appear in two blocks for each command and structure - handcoded "Valid Usage" and the implicit "Valid Usage (Implicit)" (internal issue 392). * Add the +returnedonly="false"+ attribute to WSI output structures, removing incorrectly generated implicit validity statements for slink:VkDisplayPropertiesKHR, slink:VkDisplayPlanePropertiesKHR, slink:VkDisplayModePropertiesKHR, slink:VkDisplayPlaneCapabilitiesKHR, slink:VkSurfaceCapabilitiesKHR, and slink:VkSurfaceFormatKHR structures (internal issue 486). * Update slink:VkImageLayout to require the ename:VK_IMAGE_USAGE_SAMPLED_BIT be set for sampled depth/stencil images (internal issue 487). * Use an explicit format specifier string for the date command invocation in the +Makefile+ instead of the shorthand -R option, which doesn't work on BSD and MaxOS X date commands (internal issue 500). Other Issues: * Use the terms ``allocation scope'' and ``extension scope'' instead of just ``scope'', and add them to the glossary.

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>>`

Change log for June 24, 2017 Vulkan 1.0.53 spec update: * Bump API patch number and header version number to 53 for this update. Github Issues: Internal Issues: * Clarify mappings of coordinates for mutable, compatible image views in slink:VkImageViewCreateInfo (internal issue 815). * Make ename:VK_BIND_SFR_BIT require a logical device with multiple physical devices, so that standard sparse image block dimensions are only required on systems that support multi-GPU (internal issue 835). * Convert all files from use of // refBegin .. // refEnd comments to delimit ref pages, to use of open blocks, and update style guide accordingly (internal issue 839). * Add valid usage for slink:VkWriteDescriptorSet when performing updates to a ename:VK_STORAGE_IMAGE descriptor with layout ename:VK_IMAGE_LAYOUT_GENERAL. * Add a hack to the validity generator script to support an odd interaction between flink:vkCmdFillBuffer and an extension (internal issue 853). * Remove redundant text describing slink:VkBufferCreateInfo::pname:usage, which was already covered by implicit valid usage (internal issue 854). * Update implicit validity generator script to properly handle the pname:sType and pname:pNext members of "returnedonly" structures (internal issue 874). * Note that slink:VkApplicationInfo::pname:pApplicationName & slink:VkApplicationInfo::pname:pEngineName are optional, and add missing implicit valid usage statements for flink:vkDestroyInstance. * Added missing valid usage for flink:vkCmdWriteTimestamp to require a timestamp query pool. * Simplify and/or split "`non-atomic`" valid usage statements. New Extensions: * `VK_AMD_gpu_shader_int16` * `VK_EXT_blend_operation_advanced` * `VK_EXT_sampler_filter_minmax` * `VK_NV_framebuffer_mixed_samples` ----------------------------------------------------- Note: the 1.0.52 spec wasn't published on github, so the 1.0.53 release combines both change sets. ----------------------------------------------------- Change log for June 13, 2017 Vulkan 1.0.52 spec update: * Bump API patch number and header version number to 52 for this update. Github Issues: Internal Issues: * Clarify behavior when non-coherent memory has <<memory-device-unmap-does-not-flush, not been flushed before being unmapped>> (internal issue 819). * Fix description of code:WorkgroupSize builtin to note it decorates an object, not a variable (internal issue 836). * Fix asciidoc attributes so that trailing '{plus}' symbols in [eq] style equations are rendered properly (internal issue 845). * Add language to the "`Extension Handles, Objects, Enums, and Typedefs`" section of the Procedures and Conventions document stating that any new handle type requires a corresponding entry in the elink:VkObjectType enumerated type (internal issue 856). * Update style guide to use slink macro for Vulkan handle type names, and define narrow conditions under which to use the *name and *text macros instead of *link (internal issue 886). * Add a dependency of the <<VK_KHX_device_group,VK_KHX_device_group>> extension on VK_KHX_device_group_creation to +vk.xml+ and the extension appendix. * Change the copyright on Vulkan specification asciidoc *source* files to CC-BY 4.0, and update the proprietary Khronos copyright applied to the generated *output* formats (internal issue 327). This enables broader re-use and modification of the Vulkan specification sources, while not affecting the Reciprocal IP License between Vulkan Adopters and Working Group Members. New Extensions: * `VK_NV_fill_rectangle` * `VK_NV_fragment_coverage_to_color`

Change log for July 10, 2016 Vulkan 1.0.20 spec update: * Bump API patch number and header version number to 20 for this update. Github Issues: * Replaced existing reference pages by text automatically extracted from the specification source, or generated from vk.xml in some cases. This isn't a complete solution for the reference pages, but puts them in a much better state. The ref pages (only) are now placed under a CC BY open source license, which is more current than the obsolete license previously used. Further improvements to the pages should not edit them directly, but instead concentrate on the specification source from which the ref pages are being extracted (public issues 44, 55, 160; internal issue 389).

Change log for January 15, 2018 Vulkan 1.0.68 spec update: * Bump API patch number and header version number to 68 for this update. Github Issues: * Added more details in the <<extended-functionality-extensions-compatibility, Extension Compatibility>> section, allowing explicit incompatibilities, and simplify corresponding language in the style guide, which now defers to the API Specification on this point (public issue 638). * Fix typo in description of slink:VkCommandBufferLevel::pname:level (public issue 651). * Only include extension-dependent valid usage statement for slink:VkImageSubresourceRange, and note that the extension names for header files described in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section are only valid links, when the specification being viewed is built with the corresponding extensions enabled (public issue 652). Internal Issues: * Add language to elink:VkResult specifying that when commands return an error, output parameter contents are undefined instead of unmodified (except for pname:sType and pname:pNext). Note that this is a behavior change. Add notes calling out slink:VkImageFormatProperties as an exception (internal issue 1118). * Add "`general-purpose`" to the style guide, and correct existing uses of "`general purpose`" as an adjective (internal issue 1121). * Add the ename:VK_DEBUG_REPORT_OBJECT_TYPE_VALIDATION_CACHE_EXT_EXT token for the `VK_EXT_validation_cache` extension, following the same naming pattern as other tokens in the extension, but keep the old ename:VK_DEBUG_REPORT_OBJECT_TYPE_VALIDATION_CACHE_EXT token around for backwards compatibility (internal issue 1126). Other Issues: * Specify that flink:vkCmdSetDiscardRectangleEXT does not affect copies or clears, matching existing language for the scissor rectangle test. * Move the <<boilerplate-sType, pname:sType>> definition from the boilerplate appendix to the Fundamentals chapter, putting it together with the valid usage of pname:sType rather than having the definition split across two places. * Inline all of the etext:Vk*Flags definitions, moving each one from the boilerplate appendix to appear either after the corresponding etext:Vk*FlagBits value if one is defined, or after the first structure that includes them if not.

Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Change log for September 30, 2016 Vulkan 1.0.29 spec update: * Bump API patch number and header version number to 29 for this update. Github Issues: * Remove redundant constraint on slink:VkCommandBufferInheritanceInfo::pname:queryFlags (public issue 224). * Fix typo and remove link in Note in the <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> section (public issue 359). * Fix erroneous validation statement for the pname:layout member of slink:VkComputePipelineCreateInfo (public issue 362). Internal Issues: * Restore long figure captions using asciidoc sidebar blocks, due to restrictions of asciidoc syntax (internal issue 101). * Replace most latexmath equations with comparable markup in straight asciidoc, which significantly improves time required to fully load and process the HTML forms of the Specification. There are known minor font and alignment inconsistencies with MathJax and PDF rendering of latexmath equations. Please do not file github issues about these. We are aware of the inconsistencies and will make refinements over time, while the performance improvements are compelling in at least some major browsers (internal issue 313). * Move handcoded validity statements from +vk.xml+ into the Specification body, easing work in the single-branch model. Specify the distinction between these explicit statements, and the implicit validity statements inferred from vk.xml. Validity statements now appear in two blocks for each command and structure - handcoded "Valid Usage" and the implicit "Valid Usage (Implicit)" (internal issue 392). * Add the +returnedonly="false"+ attribute to WSI output structures, removing incorrectly generated implicit validity statements for slink:VkDisplayPropertiesKHR, slink:VkDisplayPlanePropertiesKHR, slink:VkDisplayModePropertiesKHR, slink:VkDisplayPlaneCapabilitiesKHR, slink:VkSurfaceCapabilitiesKHR, and slink:VkSurfaceFormatKHR structures (internal issue 486). * Update slink:VkImageLayout to require the ename:VK_IMAGE_USAGE_SAMPLED_BIT be set for sampled depth/stencil images (internal issue 487). * Use an explicit format specifier string for the date command invocation in the +Makefile+ instead of the shorthand -R option, which doesn't work on BSD and MaxOS X date commands (internal issue 500). Other Issues: * Use the terms ``allocation scope'' and ``extension scope'' instead of just ``scope'', and add them to the glossary.

Added uniqueItems check to JSON vu schema and add clean_validusage target (internal issue 826). * Update style guide to prohibit writing non-self-contained (on a single bullet point) Valid Usage statements, and modify offending Valid Usage statements in the Specification to match, to assist with automatic extraction for the validation layers (internal issue 828). * Add ename:VK_VALIDATION_CHECK_SHADERS_EXT to elink:VkValidationCheckEXT of the `VK_EXT_validation_flags` extension, to selectively disable shader validation. * Remove duplicate valid usage statement for slink:VkImageMemoryBarrier. * Modify reflow.py script to place VUID tag anchors standalone on a line following their corresponding bullet point, and reflow the spec text accordingly (this had been pending since the initial tag deployment). New Extensions: * `VK_AMD_texture_gather_bias_lod`

Internal Issues: * Split the old <<features, Features>> chapter into four chapters: <<features, Features>>, <<limits, Limits>>, <<formats, Formats>>, and <<capabilities, Capabilities>>, with minor edits to the introductory paragraph of each chapter. Anchor names in these chapters were changed, with corresponding effects to xrefs to these anchors elsewhere in spec markup . The purpose is to make the chunked HTML spec output load faster on what was previously a single, gigantic chapter (internal issue 1554). * Add ename:VK_PIPELINE_STAGE_RAY_TRACING_SHADER_BIT_NV, to the supported pipeline stages for ename:VK_ACCESS_UNIFORM_READ, ename:VK_ACCESS_SHADER_READ, and ename:VK_ACCESS_SHADER_WRITE in the <<synchronization-access-types-supported>> table. * Correct legal name of Google, LLC in vk.xml \<tags> section and a copyright statement. * Clarify that Vulkan treats the Android code:AHARDWAREBUFFER_FORMAT_R8G8B8X8_UNORM format as RGBA, and the application is responsible for forcing the X/A component to be read as 1.0, in the <<memory-external-android-hardware-buffer-formats>> table. * Clarify the vertex order of various primitive topologies, and define the order of transform feedback vertex capture based on that.

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_AMD_gpu_shader_int16` * `VK_EXT_blend_operation_advanced` * `VK_EXT_sampler_filter_minmax` * `VK_NV_framebuffer_mixed_samples` ----------------------------------------------------- Note: the 1.0.52 spec wasn't published on github, so the 1.0.53 release combines both change sets. ----------------------------------------------------- Change log for June 13, 2017 Vulkan 1.0.52 spec update: * Bump API patch number and header version number to 52 for this update. Github Issues: Internal Issues: * Clarify behavior when non-coherent memory has <<memory-device-unmap-does-not-flush, not been flushed before being unmapped>> (internal issue 819). * Fix description of code:WorkgroupSize builtin to note it decorates an object, not a variable (internal issue 836). * Fix asciidoc attributes so that trailing '{plus}' symbols in [eq] style equations are rendered properly (internal issue 845). * Add language to the "`Extension Handles, Objects, Enums, and Typedefs`" section of the Procedures and Conventions document stating that any new handle type requires a corresponding entry in the elink:VkObjectType enumerated type (internal issue 856). * Update style guide to use slink macro for Vulkan handle type names, and define narrow conditions under which to use the *name and *text macros instead of *link (internal issue 886). * Add a dependency of the <<VK_KHX_device_group,VK_KHX_device_group>> extension on VK_KHX_device_group_creation to +vk.xml+ and the extension appendix. * Change the copyright on Vulkan specification asciidoc *source* files to CC-BY 4.0, and update the proprietary Khronos copyright applied to the generated *output* formats (internal issue 327). This enables broader re-use and modification of the Vulkan specification sources, while not affecting the Reciprocal IP License between Vulkan Adopters and Working Group Members. New Extensions: * `VK_NV_fill_rectangle` * `VK_NV_fragment_coverage_to_color`

Change log for July 10, 2016 Vulkan 1.0.20 spec update: * Bump API patch number and header version number to 20 for this update. Github Issues: * Replaced existing reference pages by text automatically extracted from the specification source, or generated from vk.xml in some cases. This isn't a complete solution for the reference pages, but puts them in a much better state. The ref pages (only) are now placed under a CC BY open source license, which is more current than the obsolete license previously used. Further improvements to the pages should not edit them directly, but instead concentrate on the specification source from which the ref pages are being extracted (public issues 44, 55, 160; internal issue 389).

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>>`

Change log for September 23, 2016 Vulkan 1.0.28 spec update: * Bump API patch number and header version number to 28 for this update.

Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Change log for July 10, 2016 Vulkan 1.0.20 spec update: * Bump API patch number and header version number to 20 for this update. Github Issues: * Replaced existing reference pages by text automatically extracted from the specification source, or generated from vk.xml in some cases. This isn't a complete solution for the reference pages, but puts them in a much better state. The ref pages (only) are now placed under a CC BY open source license, which is more current than the obsolete license previously used. Further improvements to the pages should not edit them directly, but instead concentrate on the specification source from which the ref pages are being extracted (public issues 44, 55, 160; internal issue 389).

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).

Github Issues: * Fix numerous minor issues with the VK_EXT_debug_report extension (public issues 478, 483, 486, 489, 490). Internal Issues: * Update flink:vkAllocateDescriptorSets to specify conditions under which to return ename:VK_ERROR_FRAGMENTED_POOL or ename:VK_ERROR_OUT_OF_POOL_MEMORY instead of out-of-host/out-of-device-memory, and improve the <<fundamentals-errorcodes, description of those errors (internal issue 654). * Add a NOTE documenting that flink:vkAcquireNextImageKHR can only signal a single semaphore, and how to deal with that when multiple physical devices in a logical device need to wait on it (internal issue 730). * Improve description of pname:pNext chains of slink:VkPhysicalDeviceImageFormatInfo2KHR and slink:VkImageFormatProperties2KHR (internal issue 814). * Clean up math markup issues in the <<textures, Image Operations>> chapter (internal issue 818). * Update validusage target to use more robust code for preprocessing, by making direct use of Asciidoctor's preprocessor. Added uniqueItems check to JSON vu schema and add clean_validusage target (internal issue 826). * Update style guide to prohibit writing non-self-contained (on a single bullet point) Valid Usage statements, and modify offending Valid Usage statements in the Specification to match, to assist with automatic extraction for the validation layers (internal issue 828). * Add ename:VK_VALIDATION_CHECK_SHADERS_EXT to elink:VkValidationCheckEXT of the `VK_EXT_validation_flags` extension, to selectively disable shader validation. * Remove duplicate valid usage statement for slink:VkImageMemoryBarrier. * Modify reflow.py script to place VUID tag anchors standalone on a line following their corresponding bullet point, and reflow the spec text accordingly (this had been pending since the initial tag deployment).

Internal Issues: * Remove the need for the "`noautovalidity`" attribute on extension structures in `vk.xml`. It is now implied by the "`structextends`" attribute instead (internal issue 942). * Replace uses of "`currently bound`" with "`bound`", since "`currently`" is redundant and distracting, and add a corresponding rule to the style guide (internal issue 993). * Fixed subtle issues with the last updates to flink:vkAcquireNextImageKHR language that had resulted in ambiguities (internal issue 1178). * Make it clear that only one query of a given type is allowed at a time by reordering valid usage statements for flink:vkCmdBeginQuery and flink:vkCmdEndQuery, and removing redundant ones (internal issue 1213). * Swapped OL1 and OL3 in `tessparamUL.svg` to match previous version, and fixed where "`(no edge)`" appears (internal issue 1215).

Change log for March 7, 2018 Vulkan 1.1.70 spec update: * Vulkan 1.1 initial release. Bump API patch number and header version number to 70 for this update. The patch number will be used for both Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment continuously from the previous Vulkan 1.0.69 update. NOTE: We are not publishing an updated 1.0.70 specification, or 1.1 reference pages, along with 1.1.70. There are still minor issues to work out with those build targets. However, we will soon generate all three types of documents as part of the regular spec update cycle. NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the current specification in the `master` branch. The `1.0` branch is out of date and will not be maintained, since we will be generating both 1.1 and 1.0 specifications from the `master` branch in the future. Github Issues: * Clarify how mapped memory ranges are flushed in flink:vkFlushMappedMemoryRanges (public issue 127). * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a list of tasks that each command performs, rather than necessarily being discrete pieces of hardware that one task flows through. Add a "`synchronization command`" pipeline type which all synchronization command execute (it's just TOP + BOTTOM), with an explanatory note (public issue 554). Internal Issues: * Regenerate all images used in the spec in Inkscape with a consistent look-and-feel, and adjust image size attributes so they're all legible, and not too large with respect to the spec body text (internal issue 701). * Document in the <<extensions,extensions>> appendix and in the style guide that `KHX` extensions are no longer supported or used in the Vulkan 1.1 timeframe (internal issue 714). * Remove the leftover equations_temp directory after PDF build completes (internal issue 925). * Update the <<credits, Credits (Informative)>> appendix to include contributors to Vulkan 1.1, and to list them according to the API version(s) they contributed to (internal issue 987). * Add a NOTE to the introduction explaining that interfaces defined by extensions which were promoted to Vulkan 1.1 are now expressed as aliases of the Vulkan 1.1 type (internal issue 991). * Instrument spec source conditionals so spec can be built with 1.1 features, extensions promoted to 1.1, or both (internal issues 992, 998). * Modify the XML schema and tools to support explicit aliasing of types, structures, and commands, and use this to express the promotion of 1.0 extensions to 1.1 core features, by making the extension interfaces aliases of the core features they were promoted to. Mark up promoted interfaces to allow still generating 1.0 + extension specifications (internal issue 991). * Platform names, along with corresponding preprocessor symbols to enable extensions specific to those platforms, are now reserved in vk.xml using the <platform> tag. Update the registry schema and schema specification to match (internal issue 1011). * Updated the <<textures-texel-replacement, Texel Replacement>> section to clarify that reads from invalid texels for image resources result in undefined values (internal issue 1014). * Modify description of patch version so it continues to increment across minor version changes (internal issue 1033). * Clarify and unify language describing physical device-level core and extension functionality in the <<fundamentals-validusage-extensions, Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid Usage for Newer Core Versions>>, <<initialization-functionpointers Command Function Pointers>>, <<initialization-phys-dev-extensions, Extending Physical Device From Device Extensions>> <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> sections and for flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that instance-level functionality is tied to the loader, and independent of the ICD; physical device-level functionality is tied to the ICD, and associated with device extensions; physical devices are treated more uniformly between core and extensions; and instance and physical versions can be different (internal issue 1048). * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>> section to clarify the ability for pending command buffers to transition to the invalid state after submission, and add a command buffer lifecycle diagram (internal issue 1050). * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters are ignored when push descriptors are not supported (internal issue 1054). * Specify that flink:vkCreateImage will return an error if the image is too large, in a NOTE in the slink:VkImageFormatProperties description (internal issue 1078). * Remove near-duplicate NOTEs about when to query function pointers dynamically in the <<initialization, Initialization>> chapter and replace by extending the NOTE in the <<fundamentals-abi, Application Binary Interface>> section (internal issue 1085). * Restore missing references to "`Sparse Resource Features`" in the flink:VkBufferCreateFlagBits description (internal issue 1086). * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl` specification, the <<descriptorsets, Resource Descriptors>> section and its subsections, and the <<interfaces-resources-descset, Descriptor Set Interface>> for consistency, reduction of duplicate information, and removal of GLSL correspondance/examples (internal issue 1090). * Correctly describe code:PrimitiveId as an Input for tessellation control and evaluation shaders, not an Output (internal issue 1109). * Relax the requirements on chroma offsets for nearest filtering in <<textures-implict-reconstruction, Implicit Reconstruction>> (internal issue 1116). Other Issues: * Clarify the intended relationship between specification language and certain terms defined in the Khronos Intellectual Property Rights policy. Specific changes include: ** Rewrote IP/Copyright preamble and introduction to better agree with normative language both as laid out in the introduction, and the Khronos IPR policy. ** Added notion of fully informative sections, which are now tagged with "`(Informative)`" in their titles. ** Removed non-normative uses of the phrase "`not required`" ** Clarified the distinction between terms "`optional`" and "`not required:`" as they relate to the IPR Policy, and updated specification text to use terms consistent with the intent. ** Reduced additions to RFC 2119, and ensured the specification agreed with the leaner language. ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from normative text. ** Moved several paragraphs that should not have been normative to informative notes. ** Clarified a number of definitions in the Glossary. ** Updated the document writing guide to match new terminology changes. * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire, application memory lifetime>> language that that for objects other than descriptor sets, a slink:VkDescriptorSetLayout object used in the creation of another object (such as slink:VkPipelineLayout or slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation of that object and can be safely destroyed afterwards. * Updated the <<textures-scale-factor, Scale Factor Operation>> section to use the ratio of anisotropy, rather than the integer sample rate, to perform the LOD calculation. The spec still allows use of the sample rate as the value used to calculate the LOD, but no longer requires it. * Update `vulkan_ext.c` to include all platform-related definitions from the Vulkan platform headers, following the split of the headers into platform-specific and non-platform-specific files. * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter which accidentally duplicated an anchor in the pipelines chapter. There were no reference to this anchor, fortunately. * Add valid usage statement for slink:VkWriteDescriptorSet and slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout used to allocate the source and destination sets must not have been destroyed at the time flink:vkUpdateDescriptorSets is called. * Document mapping of subgroup barrier functions to SPIR-V, and clarify a place where subgroupBarrier sounds like it's execution-only in the standalone `GL_KHR_shader_subgroup` specification. * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with the default Arial font family replaced by the sans-serif Noto font family. * Numerous minor updates to README.adoc, build scripts, Makefiles, and registry and style guide specifications to support Vulkan 1.1 outputs, use them as defaults, and remove mention of `KHX` extensions, which are no longer supported. New Extensions: * `VK_EXT_vertex_attrib_divisor`

Change log for March 3, 2019 Vulkan 1.1.102 spec update: * Update release number to 102. Public Issues: * Simplify flink:vkGetImageMemoryRequirements constraint for ename:VK_MEMORY_PROPERTY_LAZILY_ALLOCATED_BIT (public pull request 817). * Fix typo in markup of the <<textures-texel-coordinate-systems-diagrams, Texel Coordinate Systems, Corner Sampling>> image that was generating complaints from chunked HTML output generation (public pull request 928). Internal Issues: * Split the old <<features, Features>> chapter into four chapters: <<features, Features>>, <<limits, Limits>>, <<formats, Formats>>, and <<capabilities, Capabilities>>, with minor edits to the introductory paragraph of each chapter. Anchor names in these chapters were changed, with corresponding effects to xrefs to these anchors elsewhere in spec markup . The purpose is to make the chunked HTML spec output load faster on what was previously a single, gigantic chapter (internal issue 1554). * Add ename:VK_PIPELINE_STAGE_RAY_TRACING_SHADER_BIT_NV, to the supported pipeline stages for ename:VK_ACCESS_UNIFORM_READ, ename:VK_ACCESS_SHADER_READ, and ename:VK_ACCESS_SHADER_WRITE in the <<synchronization-access-types-supported>> table. * Correct legal name of Google, LLC in vk.xml \<tags> section and a copyright statement. * Clarify that Vulkan treats the Android code:AHARDWAREBUFFER_FORMAT_R8G8B8X8_UNORM format as RGBA, and the application is responsible for forcing the X/A component to be read as 1.0, in the <<memory-external-android-hardware-buffer-formats>> table. * Clarify the vertex order of various primitive topologies, and define the order of transform feedback vertex capture based on that. This involves a lot of refactoring and cleanup in the <<drawing-primitive-topologies, Primitive Topologies>>, <<geometry-input, Geometry Shader Input Primitives>> sections, and <<vertexpostproc-transform-feedback Transform Feedback>> sections, and numerous places in the <<tessellation>> chapter, New Extensions: * `VK_EXT_metal_surface` * `VK_EXT_ycbcr_image_arrays` (internal issue 1361). * `VK_NVX_image_view_handle`

Change log for September 23, 2016 Vulkan 1.0.28 spec update: * Bump API patch number and header version number to 28 for this update. Github Issues: * Minor spelling and typography cleanup, add definitions of ename:VK_FALSE and ename:VK_TRUE as just what their names say (public issues 220, 318, 325, 365; internal issues 451, 496) * Clarify that the pname:maxDescriptorSet limits in the <<features-limits-required,Required Limits>> table are n * maxPerStage limit (where n=number of supported stages) (public issue 254). * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific Macro Definitions>> appendix (public issue 314). * Add valid usage statement to slink:VkPipelineLayoutCreateInfo disallowing multiple push constant ranges for the same shader stage (public issue 340). * Clarify the elink:VkSharingMode description of what executing the "same" barriers means in case of ownership transfer (public issue 347). * Rename copyright.txt and add COPYING.md to try and reduce confusion about applicable copyrights (public issue 350). * Extend the table in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section to describe the external headers included when each etext:VK_USE_PLATFORM_* macro is defined (public issue 376). Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Change log for June 24, 2017 Vulkan 1.0.53 spec update: * Bump API patch number and header version number to 53 for this update. Github Issues: Internal Issues: * Clarify mappings of coordinates for mutable, compatible image views in slink:VkImageViewCreateInfo (internal issue 815). * Make ename:VK_BIND_SFR_BIT require a logical device with multiple physical devices, so that standard sparse image block dimensions are only required on systems that support multi-GPU (internal issue 835). * Convert all files from use of // refBegin .. // refEnd comments to delimit ref pages, to use of open blocks, and update style guide accordingly (internal issue 839). * Add valid usage for slink:VkWriteDescriptorSet when performing updates to a ename:VK_STORAGE_IMAGE descriptor with layout ename:VK_IMAGE_LAYOUT_GENERAL. * Add a hack to the validity generator script to support an odd interaction between flink:vkCmdFillBuffer and an extension (internal issue 853). * Remove redundant text describing slink:VkBufferCreateInfo::pname:usage, which was already covered by implicit valid usage (internal issue 854). * Update implicit validity generator script to properly handle the pname:sType and pname:pNext members of "returnedonly" structures (internal issue 874). * Note that slink:VkApplicationInfo::pname:pApplicationName & slink:VkApplicationInfo::pname:pEngineName are optional, and add missing implicit valid usage statements for flink:vkDestroyInstance. * Added missing valid usage for flink:vkCmdWriteTimestamp to require a timestamp query pool. * Simplify and/or split "`non-atomic`" valid usage statements.

Change log for July 10, 2016 Vulkan 1.0.20 spec update: * Bump API patch number and header version number to 20 for this update. Github Issues: * Replaced existing reference pages by text automatically extracted from the specification source, or generated from vk.xml in some cases. This isn't a complete solution for the reference pages, but puts them in a much better state. The ref pages (only) are now placed under a CC BY open source license, which is more current than the obsolete license previously used. Further improvements to the pages should not edit them directly, but instead concentrate on the specification source from which the ref pages are being extracted (public issues 44, 55, 160; internal issue 389).

Internal Issues: * Change slink:VkMappedMemoryRange valid usage to allow pname:offset + pname:size == size of the allocation. Also, if ename:VK_WHOLE_SIZE is used, require the end of the mapping to be aligned to a multiple of pname:nonCoherentAtomSize (internal issue 611). * Add issue to `VK_KHR_win32_surface` about reusing window objects from a different graphics API or Vulkan ICD (internal issue 639). * Require locations on user in/out in `GL_KHR_vulkan_glsl` (internal issue 783). * Added version info to the json validation output, and updated the schema to match (internal issue 838). * Restructure enumerated type descriptions separately from the command or structure they are used in, allowing better reference page generation (internal issue 841). * Re-sort extension appendices to be in alphabetical order within each author ID section. * Fix enum naming and clarify behavior for `VK_NVX_device_generated_commands` extension.

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).

Github Issues: * Define 'invocation group' for compute and graphics shaders. Cleanup definition and use of 'workgroup', and add glossary entries (public issue 1). * Various minor editorial fixes (public issue 33). * Clarify locations for block members in the &lt;&lt;interfaces-iointerfaces-locations,Location Assignment>> section (public issue 45). * Editorial fixes for &lt;&lt;commandbuffer-allocation,Command Buffer Allocation>> section (public issues 54, 59). * Clarify behavior of depth test in the &lt;&lt;fragops-depth,Depth Test&gt;&gt; section (public issues 80, 81). * Remove discussion of return codes from flink:vkGetPhysicalDeviceSparseImageFormatProperties and flink:vkGetImageSparseMemoryRequirements, which don't return values (public issue 82). * Allow flink:vkCmdDrawIndirect and flink:vkCmdDrawIndexedIndirect pname:drawCount of 0, as well as 1, when the multiDrawIndirect feature is not supported (public issue 88). * Remove confusing wording in the &lt;&lt;features-limits,Limits>> section describing the slink:VkPhysicalDeviceLimits pname:minTexelBufferOffsetAlignment, pname:minUniformBufferOffsetAlignment, and pname:minStorageBufferOffsetAlignment members as both minimums and maximums (public issue 91). * Clarified that only the RGB components should be affected in places where sRGB is referred to in the spec, such as ASTC formats. Minor re-wording to avoid "color space" when actively incorrect, now that we refer to the Data Format Spec which actually makes a distinction between color space and transfer function (public issue 94). * Treat pname:pPropertyCount == 0 consistently in flink:vkEnumerateInstanceLayerProperties and flink:vkEnumerateDeviceLayerProperties (public issue 99) * Cleanup minor editorial issues in chapters 14-17 (public issue 100). * Clarify definition of flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties (public issue 101). * Define the flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties pname:pLayerName parameter to be a pointer to a null-terminated UTF-8 string (public issue 101). * Rearrange "Missing information" references in mandatory format tables (public issue 101). * Clarify that the enumerated extensions returned by flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties will only include extensions provided by the platform or extensions implemented in implicitly enabled layers (public issue 101). * Miscellaneous editorial fixes. Include the Vulkan spec patch number in the PDF title. Fix label on &lt;&lt;fig-non-strict-lines,Non strict lines>> diagram. Use more easily distinguished symbols in tables in the &lt;&lt;features-required-format-support,Required Format Support>> section. Don't require FQDNs used as layer names be encoded in lower case if not possible, in the &lt;&lt;extensions-naming-conventions, Extension and Layer Naming Conventions>> section (public issues 101, 119, 121). Internal Issues: * Fixed excessive spacing in tables in XHTML (internal issue 18). * Clarify that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT applies to secondary command buffers. Previously spec only referred to the members of pname:pCommandBuffers being affected by this bit. Added a separate slink:VkSubmitInfo Valid Usage restriction specifying that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT also applies to any secondary command buffers that are recorded into the primary command buffers in pname:pCommandBuffers (internal issue 106). * Clarify that slink:VkDeviceCreateInfo::pname:pEnabledFeatures can be NULL (internal issue 117). * Remove "the value of" where it is redundant (e.g. speaking of an API parameter, struct member, or SPIR-V variable, but not when speaking of color components) (internal issue 175). * Forced patch version to always be 0 in the header. Add a "VK_API_VERSION_<major>_<minor>" macro for people to use to do the right thing. Add a VK_HEADER_VERSION which captures the header release number independent of the spec patch number (internal issue 176). * Correct description of slink:VkPipelineShaderStageCreateInfo::pname:pName to "a pointer to a null-terminated UTF-8 string" (internal issue #197). Other Commits: * Updated DataFormat spec reference to the new date for revision 5 of that spec. * Fixed KEEP option (to retain LaTeX intermediate files) in the Makefile to be included when edited there, as well as set on the command line. * Reserve and add "VK_IMG_filter_cubic" to the registry, and implement script functionality to add and remove validity from existing functions. Includes schema and readme changes. * Update GL_KHR_vulkan_glsl so push_constants do not have descriptor sets.

Github Issues: Internal Issues: * Clarify mappings of coordinates for mutable, compatible image views in slink:VkImageViewCreateInfo (internal issue 815). * Make ename:VK_BIND_SFR_BIT require a logical device with multiple physical devices, so that standard sparse image block dimensions are only required on systems that support multi-GPU (internal issue 835). * Convert all files from use of // refBegin .. // refEnd comments to delimit ref pages, to use of open blocks, and update style guide accordingly (internal issue 839). * Add valid usage for slink:VkWriteDescriptorSet when performing updates to a ename:VK_STORAGE_IMAGE descriptor with layout ename:VK_IMAGE_LAYOUT_GENERAL. * Add a hack to the validity generator script to support an odd interaction between flink:vkCmdFillBuffer and an extension (internal issue 853). * Remove redundant text describing slink:VkBufferCreateInfo::pname:usage, which was already covered by implicit valid usage (internal issue 854). * Update implicit validity generator script to properly handle the pname:sType and pname:pNext members of "returnedonly" structures (internal issue 874). * Note that slink:VkApplicationInfo::pname:pApplicationName & slink:VkApplicationInfo::pname:pEngineName are optional, and add missing implicit valid usage statements for flink:vkDestroyInstance. * Added missing valid usage for flink:vkCmdWriteTimestamp to require a timestamp query pool. * Simplify and/or split "`non-atomic`" valid usage statements. New Extensions: * `VK_AMD_gpu_shader_int16` * `VK_EXT_blend_operation_advanced` * `VK_EXT_sampler_filter_minmax` * `VK_NV_framebuffer_mixed_samples` ----------------------------------------------------- Note: the 1.0.52 spec wasn't published on github, so the 1.0.53 release combines both change sets. ----------------------------------------------------- Change log for June 13, 2017 Vulkan 1.0.52 spec update: * Bump API patch number and header version number to 52 for this update. Github Issues: Internal Issues: * Clarify behavior when non-coherent memory has <<memory-device-unmap-does-not-flush, not been flushed before being unmapped>> (internal issue 819). * Fix description of code:WorkgroupSize builtin to note it decorates an object, not a variable (internal issue 836). * Fix asciidoc attributes so that trailing '{plus}' symbols in [eq] style equations are rendered properly (internal issue 845). * Add language to the "`Extension Handles, Objects, Enums, and Typedefs`" section of the Procedures and Conventions document stating that any new handle type requires a corresponding entry in the elink:VkObjectType enumerated type (internal issue 856). * Update style guide to use slink macro for Vulkan handle type names, and define narrow conditions under which to use the *name and *text macros instead of *link (internal issue 886). * Add a dependency of the <<VK_KHX_device_group,VK_KHX_device_group>> extension on VK_KHX_device_group_creation to +vk.xml+ and the extension appendix. * Change the copyright on Vulkan specification asciidoc *source* files to CC-BY 4.0, and update the proprietary Khronos copyright applied to the generated *output* formats (internal issue 327). This enables broader re-use and modification of the Vulkan specification sources, while not affecting the Reciprocal IP License between Vulkan Adopters and Working Group Members. New Extensions: * `VK_NV_fill_rectangle` * `VK_NV_fragment_coverage_to_color`

Change log for March 10, 2016 Vulkan 1.0.6 spec update: * Bump API patch number and header version number to 6 for this update. Github Issues: * Define 'invocation group' for compute and graphics shaders. Cleanup definition and use of 'workgroup', and add glossary entries (public issue 1). * Various minor editorial fixes (public issue 33). * Clarify locations for block members in the &lt;&lt;interfaces-iointerfaces-locations,Location Assignment>> section (public issue 45). * Editorial fixes for &lt;&lt;commandbuffer-allocation,Command Buffer Allocation>> section (public issues 54, 59). * Clarify behavior of depth test in the &lt;&lt;fragops-depth,Depth Test&gt;&gt; section (public issues 80, 81). * Remove discussion of return codes from flink:vkGetPhysicalDeviceSparseImageFormatProperties and flink:vkGetImageSparseMemoryRequirements, which don't return values (public issue 82). * Allow flink:vkCmdDrawIndirect and flink:vkCmdDrawIndexedIndirect pname:drawCount of 0, as well as 1, when the multiDrawIndirect feature is not supported (public issue 88). * Remove confusing wording in the &lt;&lt;features-limits,Limits>> section describing the slink:VkPhysicalDeviceLimits pname:minTexelBufferOffsetAlignment, pname:minUniformBufferOffsetAlignment, and pname:minStorageBufferOffsetAlignment members as both minimums and maximums (public issue 91). * Clarified that only the RGB components should be affected in places where sRGB is referred to in the spec, such as ASTC formats. Minor re-wording to avoid "color space" when actively incorrect, now that we refer to the Data Format Spec which actually makes a distinction between color space and transfer function (public issue 94). * Treat pname:pPropertyCount == 0 consistently in flink:vkEnumerateInstanceLayerProperties and flink:vkEnumerateDeviceLayerProperties (public issue 99) * Cleanup minor editorial issues in chapters 14-17 (public issue 100). * Clarify definition of flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties (public issue 101). * Define the flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties pname:pLayerName parameter to be a pointer to a null-terminated UTF-8 string (public issue 101). * Rearrange "Missing information" references in mandatory format tables (public issue 101). * Clarify that the enumerated extensions returned by flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties will only include extensions provided by the platform or extensions implemented in implicitly enabled layers (public issue 101). * Miscellaneous editorial fixes. Include the Vulkan spec patch number in the PDF title. Fix label on &lt;&lt;fig-non-strict-lines,Non strict lines>> diagram. Use more easily distinguished symbols in tables in the &lt;&lt;features-required-format-support,Required Format Support>> section. Don't require FQDNs used as layer names be encoded in lower case if not possible, in the &lt;&lt;extensions-naming-conventions, Extension and Layer Naming Conventions>> section (public issues 101, 119, 121). Internal Issues: * Fixed excessive spacing in tables in XHTML (internal issue 18). * Clarify that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT applies to secondary command buffers. Previously spec only referred to the members of pname:pCommandBuffers being affected by this bit. Added a separate slink:VkSubmitInfo Valid Usage restriction specifying that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT also applies to any secondary command buffers that are recorded into the primary command buffers in pname:pCommandBuffers (internal issue 106). * Clarify that slink:VkDeviceCreateInfo::pname:pEnabledFeatures can be NULL (internal issue 117). * Remove "the value of" where it is redundant (e.g. speaking of an API parameter, struct member, or SPIR-V variable, but not when speaking of color components) (internal issue 175). * Forced patch version to always be 0 in the header. Add a "VK_API_VERSION_<major>_<minor>" macro for people to use to do the right thing. Add a VK_HEADER_VERSION which captures the header release number independent of the spec patch number (internal issue 176). * Correct description of slink:VkPipelineShaderStageCreateInfo::pname:pName to "a pointer to a null-terminated UTF-8 string" (internal issue #197). Other Commits: * Updated DataFormat spec reference to the new date for revision 5 of that spec. * Fixed KEEP option (to retain LaTeX intermediate files) in the Makefile to be included when edited there, as well as set on the command line. * Reserve and add "VK_IMG_filter_cubic" to the registry, and implement script functionality to add and remove validity from existing functions. Includes schema and readme changes. * Update GL_KHR_vulkan_glsl so push_constants do not have descriptor sets.

Change log for June 4, 2017 Vulkan 1.0.51 spec update: * Bump API patch number and header version number to 51 for this update. Github Issues: * Add Valid Usage statement to flink:vkCmdResolveImage to require that source and destination image formats match (public issue 492). * Specify that a code:char* parameter must: be a valid null-terminated string in the <<fundamentals-implicit-validity, implicit valid usage>> section (public issue 494). * Removed unnecessary VU for slink:VkPhysicalDeviceFeatures which is covered by ename:VK_ERROR_FEATURE_NOT_PRESENT already (public issue 496). * Clarify valid usage of pname:pQueueFamilyIndices in slink:VkBufferCreateInfo, slink:VkImageCreateInfo, and slink:VkSwapchainCreateInfoKHR (public issue 501). * Document that dependencies of enabled extensions must also be enabled in the <<extended-functionality-extensions-dependencies, Extension Dependencies>> section (public issue 507). Internal Issues: * Change slink:VkMappedMemoryRange valid usage to allow pname:offset + pname:size == size of the allocation. Also, if ename:VK_WHOLE_SIZE is used, require the end of the mapping to be aligned to a multiple of pname:nonCoherentAtomSize (internal issue 611). * Add issue to `VK_KHR_win32_surface` about reusing window objects from a different graphics API or Vulkan ICD (internal issue 639). * Require locations on user in/out in `GL_KHR_vulkan_glsl` (internal issue 783). * Added version info to the json validation output, and updated the schema to match (internal issue 838). * Restructure enumerated type descriptions separately from the command or structure they are used in, allowing better reference page generation (internal issue 841). * Re-sort extension appendices to be in alphabetical order within each author ID section. * Fix enum naming and clarify behavior for `VK_NVX_device_generated_commands` extension.

Change log for September 30, 2016 Vulkan 1.0.29 spec update: * Bump API patch number and header version number to 29 for this update. Github Issues: * Remove redundant constraint on slink:VkCommandBufferInheritanceInfo::pname:queryFlags (public issue 224). * Fix typo and remove link in Note in the <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> section (public issue 359). * Fix erroneous validation statement for the pname:layout member of slink:VkComputePipelineCreateInfo (public issue 362). Internal Issues: * Restore long figure captions using asciidoc sidebar blocks, due to restrictions of asciidoc syntax (internal issue 101). * Replace most latexmath equations with comparable markup in straight asciidoc, which significantly improves time required to fully load and process the HTML forms of the Specification. There are known minor font and alignment inconsistencies with MathJax and PDF rendering of latexmath equations. Please do not file github issues about these. We are aware of the inconsistencies and will make refinements over time, while the performance improvements are compelling in at least some major browsers (internal issue 313). * Move handcoded validity statements from +vk.xml+ into the Specification body, easing work in the single-branch model. Specify the distinction between these explicit statements, and the implicit validity statements inferred from vk.xml. Validity statements now appear in two blocks for each command and structure - handcoded "Valid Usage" and the implicit "Valid Usage (Implicit)" (internal issue 392). * Add the +returnedonly="false"+ attribute to WSI output structures, removing incorrectly generated implicit validity statements for slink:VkDisplayPropertiesKHR, slink:VkDisplayPlanePropertiesKHR, slink:VkDisplayModePropertiesKHR, slink:VkDisplayPlaneCapabilitiesKHR, slink:VkSurfaceCapabilitiesKHR, and slink:VkSurfaceFormatKHR structures (internal issue 486). * Update slink:VkImageLayout to require the ename:VK_IMAGE_USAGE_SAMPLED_BIT be set for sampled depth/stencil images (internal issue 487). * Use an explicit format specifier string for the date command invocation in the +Makefile+ instead of the shorthand -R option, which doesn't work on BSD and MaxOS X date commands (internal issue 500). Other Issues: * Use the terms ``allocation scope'' and ``extension scope'' instead of just ``scope'', and add them to the glossary.

This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Change log for September 30, 2016 Vulkan 1.0.29 spec update: * Bump API patch number and header version number to 29 for this update. Github Issues: * Remove redundant constraint on slink:VkCommandBufferInheritanceInfo::pname:queryFlags (public issue 224). * Fix typo and remove link in Note in the <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> section (public issue 359). * Fix erroneous validation statement for the pname:layout member of slink:VkComputePipelineCreateInfo (public issue 362). Internal Issues: * Restore long figure captions using asciidoc sidebar blocks, due to restrictions of asciidoc syntax (internal issue 101). * Replace most latexmath equations with comparable markup in straight asciidoc, which significantly improves time required to fully load and process the HTML forms of the Specification. There are known minor font and alignment inconsistencies with MathJax and PDF rendering of latexmath equations. Please do not file github issues about these. We are aware of the inconsistencies and will make refinements over time, while the performance improvements are compelling in at least some major browsers (internal issue 313). * Move handcoded validity statements from +vk.xml+ into the Specification body, easing work in the single-branch model. Specify the distinction between these explicit statements, and the implicit validity statements inferred from vk.xml. Validity statements now appear in two blocks for each command and structure - handcoded "Valid Usage" and the implicit "Valid Usage (Implicit)" (internal issue 392). * Add the +returnedonly="false"+ attribute to WSI output structures, removing incorrectly generated implicit validity statements for slink:VkDisplayPropertiesKHR, slink:VkDisplayPlanePropertiesKHR, slink:VkDisplayModePropertiesKHR, slink:VkDisplayPlaneCapabilitiesKHR, slink:VkSurfaceCapabilitiesKHR, and slink:VkSurfaceFormatKHR structures (internal issue 486). * Update slink:VkImageLayout to require the ename:VK_IMAGE_USAGE_SAMPLED_BIT be set for sampled depth/stencil images (internal issue 487). * Use an explicit format specifier string for the date command invocation in the +Makefile+ instead of the shorthand -R option, which doesn't work on BSD and MaxOS X date commands (internal issue 500). Other Issues: * Use the terms ``allocation scope'' and ``extension scope'' instead of just ``scope'', and add them to the glossary.

Github Issues: * Replaced existing reference pages by text automatically extracted from the specification source, or generated from vk.xml in some cases. This isn't a complete solution for the reference pages, but puts them in a much better state. The ref pages (only) are now placed under a CC BY open source license, which is more current than the obsolete license previously used. Further improvements to the pages should not edit them directly, but instead concentrate on the specification source from which the ref pages are being extracted (public issues 44, 55, 160; internal issue 389).

Minor re-wording to avoid "color space" when actively incorrect, now that we refer to the Data Format Spec which actually makes a distinction between color space and transfer function (public issue 94). * Treat pname:pPropertyCount == 0 consistently in flink:vkEnumerateInstanceLayerProperties and flink:vkEnumerateDeviceLayerProperties (public issue 99) * Cleanup minor editorial issues in chapters 14-17 (public issue 100). * Clarify definition of flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties (public issue 101). * Define the flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties pname:pLayerName parameter to be a pointer to a null-terminated UTF-8 string (public issue 101). * Rearrange "Missing information" references in mandatory format tables (public issue 101). * Clarify that the enumerated extensions returned by flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties will only include extensions provided by the platform or extensions implemented in implicitly enabled layers (public issue 101). * Miscellaneous editorial fixes. Include the Vulkan spec patch number in the PDF title. Fix label on &lt;&lt;fig-non-strict-lines,Non strict lines>> diagram. Use more easily distinguished symbols in tables in the &lt;&lt;features-required-format-support,Required Format Support>> section. Don't require FQDNs used as layer names be encoded in lower case if not possible, in the &lt;&lt;extensions-naming-conventions, Extension and Layer Naming Conventions>> section (public issues 101, 119, 121). Internal Issues: * Fixed excessive spacing in tables in XHTML (internal issue 18). * Clarify that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT applies to secondary command buffers. Previously spec only referred to the members of pname:pCommandBuffers being affected by this bit. Added a separate slink:VkSubmitInfo Valid Usage restriction specifying that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT also applies to any secondary command buffers that are recorded into the primary command buffers in pname:pCommandBuffers (internal issue 106). * Clarify that slink:VkDeviceCreateInfo::pname:pEnabledFeatures can be NULL (internal issue 117). * Remove "the value of" where it is redundant (e.g. speaking of an API parameter, struct member, or SPIR-V variable, but not when speaking of color components) (internal issue 175). * Forced patch version to always be 0 in the header. Add a "VK_API_VERSION_<major>_<minor>" macro for people to use to do the right thing. Add a VK_HEADER_VERSION which captures the header release number independent of the spec patch number (internal issue 176). * Correct description of slink:VkPipelineShaderStageCreateInfo::pname:pName to "a pointer to a null-terminated UTF-8 string" (internal issue #197). Other Commits: * Updated DataFormat spec reference to the new date for revision 5 of that spec. * Fixed KEEP option (to retain LaTeX intermediate files) in the Makefile to be included when edited there, as well as set on the command line. * Reserve and add "VK_IMG_filter_cubic" to the registry, and implement script functionality to add and remove validity from existing functions. Includes schema and readme changes. * Update GL_KHR_vulkan_glsl so push_constants do not have descriptor sets.

Validity statements now appear in two blocks for each command and structure - handcoded "Valid Usage" and the implicit "Valid Usage (Implicit)" (internal issue 392). * Add the +returnedonly="false"+ attribute to WSI output structures, removing incorrectly generated implicit validity statements for slink:VkDisplayPropertiesKHR, slink:VkDisplayPlanePropertiesKHR, slink:VkDisplayModePropertiesKHR, slink:VkDisplayPlaneCapabilitiesKHR, slink:VkSurfaceCapabilitiesKHR, and slink:VkSurfaceFormatKHR structures (internal issue 486). * Update slink:VkImageLayout to require the ename:VK_IMAGE_USAGE_SAMPLED_BIT be set for sampled depth/stencil images (internal issue 487). * Use an explicit format specifier string for the date command invocation in the +Makefile+ instead of the shorthand -R option, which doesn't work on BSD and MaxOS X date commands (internal issue 500). Other Issues: * Use the terms ``allocation scope'' and ``extension scope'' instead of just ``scope'', and add them to the glossary.

Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain.

Change log for June 10, 2016 Vulkan 1.0.16 spec update: * Bump API patch number and header version number to 16 for this update. Github Issues: * Clarify that integer border values are meant to be 0/1, and that integer texture lookups are sign-extended in the <<textures-format-conversion,Format Conversion>> and <<textures-texel-replacement,Texel Replacement>> sections (public issue 52). * Add logic to generate spec boilerplate without using the 'git' command-line client, needed when building from a tarball or another source of the Vulkan tree rather than a cloned git repo. Remove boilerplate as part of 'clean' target (public issue 195). * Document that color writes and clears to unused attachments have no effect for slink:VkClearAttachment and elink:VkColorComponentFlagBits (public issue 198). * Fixed flink:vkCmdExecuteCommands validity statement for sname:VkCommandBufferInheritanceInfo::pname:framebuffer. If used, it must match the framebuffer in the current renderpass instance (public issue 226). * Added valid usage language to require for all functions that set dynamic state that the currently bound graphics pipeline has the corresponding dynamic state enabled (public issue 235). Internal Issues: * Clarify for flink:vkEnumerateInstanceExtensionProperties, in the <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> section, and in the <<glossary,Glossary>> section when functionality should be exposed as an instance extension, as a device extension, or as both (internal issue 109). * Place WorkgroupSize in alphabetical order in the <<interfaces-builtin-variables,Built-in Variables>> section (internal issue 323). * Corrects valid usage in vkEndRenderPass to only affect primary render passes, as secondaries may be entirely within a render pass, and should be able to be ended (previous language disallowed that) (internal issue 338). * Fix relational operator from <= to >= in the <<features-extentperimagetype,Allowed Extent Values>> section (internal issue 343). * Disallow recursion under SPIR-V entry points in the <<spirvenv-module-validation,Validation Rules within a Module>> section (internal SPIR-V issue 37). Other Commits: * Use standard Python ElementTree package instead of lxml.etree in header / validation layer / include autogeneration from XML, reducing platform dependencies.

Github Issues: * Replaced existing reference pages by text automatically extracted from the specification source, or generated from vk.xml in some cases. This isn't a complete solution for the reference pages, but puts them in a much better state. The ref pages (only) are now placed under a CC BY open source license, which is more current than the obsolete license previously used. Further improvements to the pages should not edit them directly, but instead concentrate on the specification source from which the ref pages are being extracted (public issues 44, 55, 160; internal issue 389).

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>>`

Change log for March 10, 2016 Vulkan 1.0.6 spec update: * Bump API patch number and header version number to 6 for this update. Github Issues: * Define 'invocation group' for compute and graphics shaders. Cleanup definition and use of 'workgroup', and add glossary entries (public issue 1). * Various minor editorial fixes (public issue 33). * Clarify locations for block members in the &lt;&lt;interfaces-iointerfaces-locations,Location Assignment>> section (public issue 45). * Editorial fixes for &lt;&lt;commandbuffer-allocation,Command Buffer Allocation>> section (public issues 54, 59). * Clarify behavior of depth test in the &lt;&lt;fragops-depth,Depth Test&gt;&gt; section (public issues 80, 81). * Remove discussion of return codes from flink:vkGetPhysicalDeviceSparseImageFormatProperties and flink:vkGetImageSparseMemoryRequirements, which don't return values (public issue 82). * Allow flink:vkCmdDrawIndirect and flink:vkCmdDrawIndexedIndirect pname:drawCount of 0, as well as 1, when the multiDrawIndirect feature is not supported (public issue 88). * Remove confusing wording in the &lt;&lt;features-limits,Limits>> section describing the slink:VkPhysicalDeviceLimits pname:minTexelBufferOffsetAlignment, pname:minUniformBufferOffsetAlignment, and pname:minStorageBufferOffsetAlignment members as both minimums and maximums (public issue 91). * Clarified that only the RGB components should be affected in places where sRGB is referred to in the spec, such as ASTC formats. Minor re-wording to avoid "color space" when actively incorrect, now that we refer to the Data Format Spec which actually makes a distinction between color space and transfer function (public issue 94). * Treat pname:pPropertyCount == 0 consistently in flink:vkEnumerateInstanceLayerProperties and flink:vkEnumerateDeviceLayerProperties (public issue 99) * Cleanup minor editorial issues in chapters 14-17 (public issue 100). * Clarify definition of flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties (public issue 101). * Define the flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties pname:pLayerName parameter to be a pointer to a null-terminated UTF-8 string (public issue 101). * Rearrange "Missing information" references in mandatory format tables (public issue 101). * Clarify that the enumerated extensions returned by flink:vkEnumerateInstanceExtensionProperties and flink:vkEnumerateDeviceExtensionProperties will only include extensions provided by the platform or extensions implemented in implicitly enabled layers (public issue 101). * Miscellaneous editorial fixes. Include the Vulkan spec patch number in the PDF title. Fix label on &lt;&lt;fig-non-strict-lines,Non strict lines>> diagram. Use more easily distinguished symbols in tables in the &lt;&lt;features-required-format-support,Required Format Support>> section. Don't require FQDNs used as layer names be encoded in lower case if not possible, in the &lt;&lt;extensions-naming-conventions, Extension and Layer Naming Conventions>> section (public issues 101, 119, 121). Internal Issues: * Fixed excessive spacing in tables in XHTML (internal issue 18). * Clarify that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT applies to secondary command buffers. Previously spec only referred to the members of pname:pCommandBuffers being affected by this bit. Added a separate slink:VkSubmitInfo Valid Usage restriction specifying that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT also applies to any secondary command buffers that are recorded into the primary command buffers in pname:pCommandBuffers (internal issue 106). * Clarify that slink:VkDeviceCreateInfo::pname:pEnabledFeatures can be NULL (internal issue 117). * Remove "the value of" where it is redundant (e.g. speaking of an API parameter, struct member, or SPIR-V variable, but not when speaking of color components) (internal issue 175). * Forced patch version to always be 0 in the header. Add a "VK_API_VERSION_<major>_<minor>" macro for people to use to do the right thing. Add a VK_HEADER_VERSION which captures the header release number independent of the spec patch number (internal issue 176). * Correct description of slink:VkPipelineShaderStageCreateInfo::pname:pName to "a pointer to a null-terminated UTF-8 string" (internal issue #197). Other Commits: * Updated DataFormat spec reference to the new date for revision 5 of that spec. * Fixed KEEP option (to retain LaTeX intermediate files) in the Makefile to be included when edited there, as well as set on the command line. * Reserve and add "VK_IMG_filter_cubic" to the registry, and implement script functionality to add and remove validity from existing functions. Includes schema and readme changes. * Update GL_KHR_vulkan_glsl so push_constants do not have descriptor sets.

Change log for September 23, 2016 Vulkan 1.0.28 spec update: * Bump API patch number and header version number to 28 for this update. Github Issues: * Minor spelling and typography cleanup, add definitions of ename:VK_FALSE and ename:VK_TRUE as just what their names say (public issues 220, 318, 325, 365; internal issues 451, 496) * Clarify that the pname:maxDescriptorSet limits in the <<features-limits-required,Required Limits>> table are n * maxPerStage limit (where n=number of supported stages) (public issue 254). * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific Macro Definitions>> appendix (public issue 314). * Add valid usage statement to slink:VkPipelineLayoutCreateInfo disallowing multiple push constant ranges for the same shader stage (public issue 340). * Clarify the elink:VkSharingMode description of what executing the "same" barriers means in case of ownership transfer (public issue 347). * Rename copyright.txt and add COPYING.md to try and reduce confusion about applicable copyrights (public issue 350). * Extend the table in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section to describe the external headers included when each etext:VK_USE_PLATFORM_* macro is defined (public issue 376). Internal Issues: * Add "Revision History" to the PDF outputs following the table of contents, to match HTML outputs (internal issue 43). * Clarified that flink:vkMapMemory may fail due to virtual address space limitations (internal issue 346). * Add +refBody+ comment markup for ref page autoextraction when required (internal issue 400). * Document proper use of "mipmap" and "mip" in the style guide API naming rules, matching the spelling rules (internal issue 471). * Tweak the <<extensions,Layers and Extensions>> appendix to note that the Specification may be built with arbitrary combinations of extensions (internal issue 483). * Remove incorrect statement allowing slink:VkClearAttachment::pname:colorAttachment to be >= slink:VkSubpassDescription::pname:colorAttachmentCount (internal issue 488). * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is expressed in terms of the pname:maxViewportDimensions but this is actually two values. Clarify that it's based on the larger of the two (if they differ) (internal issue 499). Other Issues: * Reflowed text of the entire spec using the 'reflow' Makefile gater, to (hopefully) reduce future internal git churn as edits are made and extensions added in return for one-time pain. This has no perceptible change on the spec outputs but considerable changes on the asciidoc source (internal issue 367).

Change log for September 30, 2016 Vulkan 1.0.29 spec update: * Bump API patch number and header version number to 29 for this update. Github Issues: * Remove redundant constraint on slink:VkCommandBufferInheritanceInfo::pname:queryFlags (public issue 224). * Fix typo and remove link in Note in the <<extended-functionality-instance-extensions-and-devices, Instance Extensions and Device Extensions>> section (public issue 359). * Fix erroneous validation statement for the pname:layout member of slink:VkComputePipelineCreateInfo (public issue 362). Internal Issues: * Restore long figure captions using asciidoc sidebar blocks, due to restrictions of asciidoc syntax (internal issue 101). * Replace most latexmath equations with comparable markup in straight asciidoc, which significantly improves time required to fully load and process the HTML forms of the Specification. There are known minor font and alignment inconsistencies with MathJax and PDF rendering of latexmath equations. Please do not file github issues about these. We are aware of the inconsistencies and will make refinements over time, while the performance improvements are compelling in at least some major browsers (internal issue 313). * Move handcoded validity statements from +vk.xml+ into the Specification body, easing work in the single-branch model. Specify the distinction between these explicit statements, and the implicit validity statements inferred from vk.xml. Validity statements now appear in two blocks for each command and structure - handcoded "Valid Usage" and the implicit "Valid Usage (Implicit)" (internal issue 392). * Add the +returnedonly="false"+ attribute to WSI output structures, removing incorrectly generated implicit validity statements for slink:VkDisplayPropertiesKHR, slink:VkDisplayPlanePropertiesKHR, slink:VkDisplayModePropertiesKHR, slink:VkDisplayPlaneCapabilitiesKHR, slink:VkSurfaceCapabilitiesKHR, and slink:VkSurfaceFormatKHR structures (internal issue 486). * Update slink:VkImageLayout to require the ename:VK_IMAGE_USAGE_SAMPLED_BIT be set for sampled depth/stencil images (internal issue 487). * Use an explicit format specifier string for the date command invocation in the +Makefile+ instead of the shorthand -R option, which doesn't work on BSD and MaxOS X date commands (internal issue 500). Other Issues: * Use the terms ``allocation scope'' and ``extension scope'' instead of just ``scope'', and add them to the glossary.

Change log for June 24, 2017 Vulkan 1.0.53 spec update: * Bump API patch number and header version number to 53 for this update. Github Issues: Internal Issues: * Clarify mappings of coordinates for mutable, compatible image views in slink:VkImageViewCreateInfo (internal issue 815). * Make ename:VK_BIND_SFR_BIT require a logical device with multiple physical devices, so that standard sparse image block dimensions are only required on systems that support multi-GPU (internal issue 835). * Convert all files from use of // refBegin .. // refEnd comments to delimit ref pages, to use of open blocks, and update style guide accordingly (internal issue 839). * Add valid usage for slink:VkWriteDescriptorSet when performing updates to a ename:VK_STORAGE_IMAGE descriptor with layout ename:VK_IMAGE_LAYOUT_GENERAL. * Add a hack to the validity generator script to support an odd interaction between flink:vkCmdFillBuffer and an extension (internal issue 853). * Remove redundant text describing slink:VkBufferCreateInfo::pname:usage, which was already covered by implicit valid usage (internal issue 854). * Update implicit validity generator script to properly handle the pname:sType and pname:pNext members of "returnedonly" structures (internal issue 874). * Note that slink:VkApplicationInfo::pname:pApplicationName & slink:VkApplicationInfo::pname:pEngineName are optional, and add missing implicit valid usage statements for flink:vkDestroyInstance. * Added missing valid usage for flink:vkCmdWriteTimestamp to require a timestamp query pool. * Simplify and/or split "`non-atomic`" valid usage statements. New Extensions: * `VK_AMD_gpu_shader_int16` * `VK_EXT_blend_operation_advanced` * `VK_EXT_sampler_filter_minmax` * `VK_NV_framebuffer_mixed_samples` ----------------------------------------------------- Note: the 1.0.52 spec wasn't published on github, so the 1.0.53 release combines both change sets. ----------------------------------------------------- Change log for June 13, 2017 Vulkan 1.0.52 spec update: * Bump API patch number and header version number to 52 for this update. Github Issues: Internal Issues: * Clarify behavior when non-coherent memory has <<memory-device-unmap-does-not-flush, not been flushed before being unmapped>> (internal issue 819). * Fix description of code:WorkgroupSize builtin to note it decorates an object, not a variable (internal issue 836). * Fix asciidoc attributes so that trailing '{plus}' symbols in [eq] style equations are rendered properly (internal issue 845). * Add language to the "`Extension Handles, Objects, Enums, and Typedefs`" section of the Procedures and Conventions document stating that any new handle type requires a corresponding entry in the elink:VkObjectType enumerated type (internal issue 856). * Update style guide to use slink macro for Vulkan handle type names, and define narrow conditions under which to use the *name and *text macros instead of *link (internal issue 886). * Add a dependency of the <<VK_KHX_device_group,VK_KHX_device_group>> extension on VK_KHX_device_group_creation to +vk.xml+ and the extension appendix. * Change the copyright on Vulkan specification asciidoc *source* files to CC-BY 4.0, and update the proprietary Khronos copyright applied to the generated *output* formats (internal issue 327). This enables broader re-use and modification of the Vulkan specification sources, while not affecting the Reciprocal IP License between Vulkan Adopters and Working Group Members.

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).

Add notes calling out slink:VkImageFormatProperties as an exception (internal issue 1118). * Add "`general-purpose`" to the style guide, and correct existing uses of "`general purpose`" as an adjective (internal issue 1121). * Add the ename:VK_DEBUG_REPORT_OBJECT_TYPE_VALIDATION_CACHE_EXT_EXT token for the `VK_EXT_validation_cache` extension, following the same naming pattern as other tokens in the extension, but keep the old ename:VK_DEBUG_REPORT_OBJECT_TYPE_VALIDATION_CACHE_EXT token around for backwards compatibility (internal issue 1126). Other Issues: * Specify that flink:vkCmdSetDiscardRectangleEXT does not affect copies or clears, matching existing language for the scissor rectangle test. * Move the <<boilerplate-sType, pname:sType>> definition from the boilerplate appendix to the Fundamentals chapter, putting it together with the valid usage of pname:sType rather than having the definition split across two places. * Inline all of the etext:Vk*Flags definitions, moving each one from the boilerplate appendix to appear either after the corresponding etext:Vk*FlagBits value if one is defined, or after the first structure that includes them if not.

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>>`

Change log for January 15, 2018 Vulkan 1.0.68 spec update: * Bump API patch number and header version number to 68 for this update. Github Issues: * Added more details in the <<extended-functionality-extensions-compatibility, Extension Compatibility>> section, allowing explicit incompatibilities, and simplify corresponding language in the style guide, which now defers to the API Specification on this point (public issue 638). * Fix typo in description of slink:VkCommandBufferLevel::pname:level (public issue 651). * Only include extension-dependent valid usage statement for slink:VkImageSubresourceRange, and note that the extension names for header files described in the <<boilerplate-wsi-header, Window System-Specific Header Control>> section are only valid links, when the specification being viewed is built with the corresponding extensions enabled (public issue 652). Internal Issues: * Add language to elink:VkResult specifying that when commands return an error, output parameter contents are undefined instead of unmodified (except for pname:sType and pname:pNext). Note that this is a behavior change. Add notes calling out slink:VkImageFormatProperties as an exception (internal issue 1118). * Add "`general-purpose`" to the style guide, and correct existing uses of "`general purpose`" as an adjective (internal issue 1121). * Add the ename:VK_DEBUG_REPORT_OBJECT_TYPE_VALIDATION_CACHE_EXT_EXT token for the `VK_EXT_validation_cache` extension, following the same naming pattern as other tokens in the extension, but keep the old ename:VK_DEBUG_REPORT_OBJECT_TYPE_VALIDATION_CACHE_EXT token around for backwards compatibility (internal issue 1126). Other Issues: * Specify that flink:vkCmdSetDiscardRectangleEXT does not affect copies or clears, matching existing language for the scissor rectangle test. * Move the <<boilerplate-sType, pname:sType>> definition from the boilerplate appendix to the Fundamentals chapter, putting it together with the valid usage of pname:sType rather than having the definition split across two places. * Inline all of the etext:Vk*Flags definitions, moving each one from the boilerplate appendix to appear either after the corresponding etext:Vk*FlagBits value if one is defined, or after the first structure that includes them if not.

Change log for November 12, 2018 Vulkan 1.1.92 spec update: * Update release number to 92. Public Issues: * Move and modify valid usage statements dealing with pname:aspectMask in flink:vkCmdClearColorImage, flink:vkCmdClearDepthStencilImage, and slink:VkClearAttachment, so they are in places where all necessary information is available (public issue 529). * Fix math markup in <<textures-texel-anisotropic-filtering, Texel Anisotropic Filtering>> (public pull request 840). * Fix misspellings (public pull request 845). Internal Issues: * Add installation instructions and a Makefile "`chunked`" target for chunked HTML generation (internal issue 1352). * Fix pipeline mesh diagram style; also fix a minor bug in the classic pipeline diagram where vertex/index buffers wrongly fed into the vertex shader (internal issue 1436). * Make asciidoctor ERROR output raise an error, and don't suppress executed command output from CI make invocation (internal issue 1454). * Minor typo fixes and clarifications for `VK_NV_raytracing`. * Cleanup extension-specific properties ** Remove duplicated documentation for pname:maxDiscardRectangles, pname:pointClippingBehavior, and pname:maxVertexAttribDivisor (they shouldn't be documented with the other members of slink:VkPhysicalDeviceLimits at all). ** Remove duplicate anchor for pname:maxVertexAttribDivisor ** Consistently document stext:VkPhysicalDevice<Extension>PropertiesKHR *** Always document pname:sType/pname:pNext (was inconsistent before) *** Always mention chaining to slink:VkPhysicalDeviceProperties2 (and not as slink:VkPhysicalDeviceProperties2KHR) *** Always include Valid Usage statements last * Update Makefile 'checklinks' target and associated scripts, and fix markup problems identified by checkLinks.py, so that we can rely on the checklinks script as part of Gitlab CI.
