Change log for September 8, 2019 Vulkan 1.1.122 spec update:
* Update release number to 122.
Internal Issues:
* Add style guide language on not using standalone `+` signs (internal
issue 736); not using leading whitespace for markup (internal issue
747); and on keeping descriptions of a single API in a contiguous block
of markup (internal issue 949), and apply them to the specification.
* Add a glossary definition of "`constant integral expression`", pointing
to the SPIR-V "`constant instruction`" definition (internal issue 1225).
* Many minor edits to improve writing style consistency and capture
additional style guidelines (internal issue 1553).
* Clarify that <<fragops-depth-write, depth writes are not performed>> if
there is no depth framebuffer attachment (internal issue 1771).
* Allow implementations to use rectangular line style of interpolation for
<<primsrast-lines-bresenham, wide Bresenham lines>>, though replicating
attributes is still preferred. Clarify that code:FragCoord is not
replicated (internal issue 1772).
* Resolve a contradiction in valid usage statements for
slink:VkImageCreateInfo and slink:VkImageStencilUsageCreateInfoEXT
(internal issue 1773).
* Add style guide discussion of markup for indented equations, and use
markup workaround for asciidoctor 2 compatibility (internal issue 1793).
* Deprecate the `<<VK_EXT_validation_flags>>` extension in `vk.xml` and
the extension appendix (internal issue 1801).
* Add a new checker script `scripts/xml_consistency.py`. This is not
currently run as part of internal CI (internal merge request 3285).
* Correct "`an`" -> "`a`" prepositions where needed (internal merge
request 3334).
* Clarify that the <<features-uniformBufferStandardLayout,
pname:uniformBufferStandardLayout>> feature is only required when the
extension defining it is supported (internal merge request 3341).
* Bring scripts into closer sync with OpenXR, mainly through conversion of
comments to docstrings where appropriate, and add gen-scripts-docs.sh
(internal merge request 3324).
* Correct pname:maxDrawMeshTasksCount to 2^16^-1 in the <<limits-required,
Required Limits>> table (internal merge requests 3361).
New Extensions
* `<<VK_IMG_format_pvrtc>>` (public issue 512).

Change log for July 28, 2019 Vulkan 1.1.117 spec update:
* Update release number to 117.
Github Issues:
* Add ename:VK_STENCIL_FACE_FRONT_AND_BACK for naming consistency, and
alias the old ename:VK_STENCIL_FRONT_AND_BACK for backwards
compatibility (public issue 991).
* Fix minor issues with valid usage statements for
flink:vkCreateFramebuffer, slink:VkFramebufferCreateInfo, and
slink:VkRenderPassBeginInfo when the `<<VK_KHR_imageless_framebuffer>>`
extension is enabled (public issue 998).
* Clarify the subpass dependency requirement in the
<<renderpass-layout-transitions>> section to eliminate the need for a
subpass dependency for either the same or different layouts as long as
they're both read-only (relates to
https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/948).
Internal Issues:
* Document that <<extendingvulkan-compatibility-promotion, backwards
compatibility aliases are not promoted>> as part of promoting an
extension (internal issue 1677).
* Update VK_ANDROID_native_buffer extension to spec version 8 (internal
issue 1753).
* Add missing section to the <<VK_KHR_shader_controls_v4_incompatibility,
VK_KHR_shader_float_controls>> extension appendix describing
the reason for the breaking API change in version 4 of the extension,
and correct the version to 4 in `vk.xml` (internal merge request
3275).
* Add valid usage statements to slink:VkAccelerationStructureInfoNV
requiring the ename:VK_BUFFER_USAGE_RAY_TRACING_BIT_NV usage flag for
buffers used in acceleration structure building.
New Extensions:
* `<<VK_EXT_line_rasterization>>`
* `<<VK_EXT_texture_compression_astc_hdr>>`
* `<<VK_EXT_index_type_uint8>>`

Change log for June 10, 2019 Vulkan 1.1.111 spec update:
* Update release number to 111.
Github Issues:
* Clean up flink:vkGetPhysicalDeviceSurfaceFormatsKHR and
flink:vkGetPhysicalDeviceSurfaceFormats2KHR to drop the
ename:VK_FORMAT_UNDEFINED case, require callers pass a supported
surface, and rearrange some validation-related language (public issue
207).
* Allow dynamic and nonuniform indexing of acceleration structures in the
<<interfaces-resources-descset, Descriptor Set Interface>> section
(public KhronosGroup/glslang issue 1766).
Internal Issues:
* Clarify when images require the use of YCbCr samplers for
slink:VkWriteDescriptorSet and slink:VkImageViewCreateInfo (internal
issue 1639).
* Remove the "`block`" language around <<features-robustBufferAccess,
vectorizing and robust buffer access>> (internal issue 1642).
* Allow code:OpTypeImageFormat == code:Unknown for input attachments in
the <<interfaces-resources-descset, Descriptor Set Interface>> section
(internal issue 1645).
* Fix asciidoctor conditionals around
ename:VK_ERROR_FULL_SCREEN_EXCLUSIVE_MODE_LOST_EXT in the
<<fundamentals-errorcodes>> section (internal issue 1679).
* Remove error codes from `vk.xml` for
flink:vkUninitializePerformanceApiINTEL, which has a `void` return type
(internal issue 1704).
* Various subgroup-related fixes in the <<spirvenv-capabilities,
Capabilities>>, <<shaders-subgroup-arithmetic, Arithmetic Subgroup
Operations>>, <<shaders-subgroup-clustered, Clustered Subgroup
Operations>>, and <<shaders-subgroup-partitioned, Partitioned Subgroup
Operations>> sections (internal merge request 3164).
* Fix asciidoctor markup affecting math rendering in the <<Precision of
core SPIR-V Instructions>> table (internal merge request 3166).
* Fix incorrect reference to flink:vkGetPhysicalDeviceFeatures2KHR in the
description of slink:VkPhysicalDeviceASTCDecodeFeaturesEXT (internal
merge request 3169).
* Fix a non-sentence in the introduction to the <<textures, Image
Operations Overview>> section (internal merge request 3184).
* Minor markup, grammar, and typo fixes for the
`<<NV_shader_sm_builtins>>` extension spec language (internal merge
request 3189).
* Clarify that 1D and 1D array format support is optional for cubic
filters, immediately following the <<formats-mandatory-features-astc,
Mandatory ASTC LDR format support>> table (internal merge request 3194).

Change log for May 24, 2019 Vulkan 1.1.109 spec update:
* Update release number to 109.
Github Issues:
* Require matching for physical devices to be in a device group in the
<<devsandqueues-devices, Devices>> section (public issue 695).
* Fix typo in an equation in the <<fragmentdensitymap-fetch-density-value,
Fetch Density Value>> section (public issue 954).
* Fix styleguide links (public pull request 965).
Internal Issues:
* Allow <<renderpass-compatibility, compatibility of single-subpass
renderpasses>> with different resolve attachments (internal issue 1464).
* Add some missing empty flags types to API spec so custom refpage
generation doesn't break (internal issue 1607).
* Add a "`SPIR-V Sampled Type`" column to the <<formats-numericformat,
Interpretation of Numeric Formats>> table, and clarify the requirement
that the code:OpTypeImage sampled type match the bound image's numeric
format for slink:VkClearColorValue and in the
<<interfaces-resources-descset, Descriptor Set Interface>> section
(internal issue 1646).
* Fix a typo in the <<tessellation-quad-tessellation, Quad Tessellation>>
section which should refer to rectangles, not triangles (internal issue
1667).
* Clarify the definition of time domains in elink:VkTimeDomainEXT
(internal merge request 3110).
* Add R10X6 and R12X4 formats to the <<formats-mandatory-features-10bit>>
table (internal merge request 3137).
* Don't require extern sync on wait/signal semaphores in `vk.xml` for
flink:vkQueueSubmit and flink:vkQueueBindSparse (internal merge request
3116).

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 March 11, 2019 Vulkan 1.1.103 spec update:
* Update release number to 103.
Public Issues:
* Remove (unnecessary) scoped modification order case from the memory
model <<memory-model-location-ordered, location-ordered>> definition
(public pull request 924).
* Add an <<memory-model-acyclicity, acyclicity>> axiom to the memory model
(public pull request 927).
Internal Issues:
* Fix reversed logic of slink:VkFormatProperties discussion of multi-plane
formats and ename:VK_FORMAT_FEATURE_DISJOINT_BIT (internal issue 1493).
* Clarify how slink:VkImageStencilUsageCreateInfoEXT works, including new
valid usage statements for flink:vkCmdClearDepthStencilImage, and the
<<copies, Common Operation>> section of the Copy Commands chapter
(internal issue 1565).
* Update <<spirvenv-precision-operation, Precision and Operation of SPIR-V
Instructions>> section to require that denorms be preserved by several
instructions that don't perform any mathematical operations (internal
issue 1584).
* Remove duplicate valid usage statement from flink:vkAcquireNextImageKHR
(internal merge request 3062).

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`
