* Update release number to 98.
Public Issues:
* Fix missing markup in flink:vkDestroyPipelineLayout valid usage
statement (pull request 882).
* Add missing contributors for `<<VK_EXT_buffer_device_address>>` (public
pull request 891).
Internal Issues:
* Detect nested bullet points in valid usage blocks and warn about them
during VUID assignment (internal issue 1382).
* Update the style guide to document the process for reserving new bits in
bitmask types (internal issue 1411).
* Clarify for slink:VkApplicationInfo::pname:apiVersion and in the
<<fundamentals-validusage-versions, Valid Usage for Newer Core
Versions>> section when it is valid for an application to use a certain
version of Vulkan API functionality (for an instance and for a
device/physical device); and when the validation layers must generate an
error (internal issue 1412).
* Add optional <<memory-model-availability-visibility, transitive
availability/visibility operations to the memory model, including a new
pname:vulkanMemoryModelAvailabilityVisibilityChains feature for
slink:VkPhysicalDeviceVulkanMemoryModelFeaturesKHR (internal issue
1460).
* Add the code:StorageBuffer storage class to those in the
<<interfaces-resources-descset, Descriptor Set Interface>> (internal
issue 1480).

(internal issue 1522).
* Correctly round the code:OpVectorTimesScalar and
code:OpMatrixTimesScalar SPIR-V operations in the <<Precision of core
SPIR-V Instructions>> table (internal merge request 2996).
* Work around cases in flink:vkCmdBeginTransformFeedbackEXT,
flink:vkCmdEndTransformFeedbackEXT, and
slink:VkPipelineCoverageModulationStateCreateInfoNV where an array
parameter is `optional` but the length is not in `vk.xml`. This is an
interim fix using `noautovalidity` + handcoded VU replacing those that
should be autogenerated (internal issue 2944 and
https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/480).
* Remove redundant capability validation of the code:float16 and code:int8
SPIR-V capabilities from the <<spirvenv-capabilities, Capabilities>>
section, since they are already covered in the preceding table.
* Update check_spec_links script, including validation for reference page
open blocks. Fix errors identified by the script.
* Update release number to 97.
Public Issues:
* Add a special case to the <<renderpass-compatibility, Render Pass
Compatibility>> rules allowing single-subpass renderpasses to be
compatible even if they have different resolve attachment references
(public issue 835).
* Fix the miss shader binding table record address rule in the
<<shader-binding-table-indexing-rules, Miss Shaders>> section to index
by code:missIndex, not code:sbtOffset (public issue 875).
Internal Issues:
* Add a missing anchor to the elink:VkSamplerCreateFlagBits language
(internal issue 1483).
* Add missing implicit valid usage include for slink:VkHdrMetadataEXT and
corresponding `noautovalidity` attributes in `vk.xml` for the
externally-defined metadata properties (internal issue 1514).
* Remove restrictions on the `mask` parameter of SPIR-V's
code:OpGroupNonUniformXor in the <<spirvenv-module-validation,
Validation Rules within a Module>> appendix (internal merge request
2971).
* Restore `noautovalidity` attribute for
slink:VkPipelineViewportWScalingStateCreateInfoNV::pname:pViewportWScalings
in `vk.xml` (internal merge request 2975).

* Fix links in optimized PDF output (public PR 879).
Internal Issues:
* Add a link to GitHub contributors in the <<credits, Other Credits>>
section (internal issue 808).
* Clarify the behavior of command aliases described in the <<versions,Core
Revisions>> and <<initialization-functionpointers, Command Function
Pointers>> sections and the registry schema document with respect to
whether they are or are not the same entry point, and what the behaviour
of the ftext:vkGet*ProcAddr commands is for each alias (internal issue
1462).
* Update slink:VkPipelineShaderStageCreateInfo valid usage statements for
writing to code:Layer and code:viewportIndex to apply to any vertex
processing stage (internal issue 1475).
* Make sparse image creation optional for Y'C~B~C~R~ formats in the
<<features-required-format-support, Required Format Support>> section
and the <<features-formats-requiring-sampler-ycbcr-conversion, Formats
requiring sampler Y'C~B~C~R~ conversion for
ename:VK_IMAGE_ASPECT_COLOR_BIT image views>> table (internal issue
1476).
* Modify the valid usage statement for
flink:vkCmdDrawIndirectByteCountEXT::pname:vertexStride to use the
pname:maxTransformFeedbackBufferDataStride limit rather than the
pname:maxVertexInputBindingStride limit, which is a better match for
transform feedback related operations (internal issue 1487).
* Changed all members of slink:VkPhysicalDevicePCIBusInfoPropertiesEXT to
have the `uint32_t` type. This is an imcompatible change to an EXT
that's very recently released; although this is against usual Vulkan WG
policy, we discussed and consider this an acceptable risk, but have
polled the mesa-dev list in case there are use cases we missed (internal
issue 1492).
* Set spec vetsion to 1 for `VK_GOOGLE_hlsl_functionality1` and
`VK_GOOGLE_decorate_string` in `vk.xml` (internal MR 2948).
* Remove redundant valid usage statement `VkImageCreateInfo-pNext-02395`
(internal MR 2950).
* Add `check_spec_links.py` script, use it in Gitlab CI, and fix many
minor markup issues discovered by the script (internal MR 2955).

the `VK_EXT_debug_utils` extension (public pull request 794).
* Replace references to `VK_NV_dedicated_allocation` with links to the
corresponding slink:slink:VkMemoryDedicatedRequirements and
slink:slink:VkMemoryDedicatedAllocateInfo structures in the description
of elink:VkExternalMemoryFeatureFlagBits (public issue 801).
* Fix miscellaneous minor markup and spelling issues in
`VK_NV_ray_tracing` extension (public pull request 860).
* Remove "returnedonly" from XML for
slink:VkPhysicalDeviceInlineUniformBlockFeaturesEXT and
slink:VkPhysicalDeviceVulkanMemoryModelFeaturesKHR (public issue 862).
Internal Issues:
* Add to the description of the
<<features-limits-maxComputeSharedMemorySize,
pname:maxCompureSharedMemorySize>> feature to state the shared variables
should be packed at least as tightly as std430 (internal issue 1386).

flink:vkCmdBindShadingRateImageNV, flink:vkCmdBeginRenderPass, and
slink:VkImageStencilUsageCreateInfoEXT (internal issue 1432).

parameters (public pull request 851).
* Fix miscellaneous typos (public pull request 855).
* Add driver ID for Pastel (public pull request 856).
* Add missing include directive for slink:VkMemoryWin32HandlePropertiesKHR
implicit valid usage statements (public pull request 857).
Internal Issues:
* Restrict the storage classes permitted for SPIR-V atomics to what is
actually supported, in the <<spirvenv-module-validation, Validation
Rules within a Module>> section (internal issue 1123).
* Add a missing Valid Usage statement to slink:VkRenderPassCreateInfo for
the case pname:stencilLoadOp == ename:VK_LOAD_OP_CLEAR, pname:layout ==

1408).
* Modify optimize-pdf script and Makefile to retain non-optimized original
PDF on errors (internal issue 1435).

slink:VkSubpassDescription, slink:VkSubpassDescription2KHR,
slink:VkSubpassDependency2KHR, flink:vkCmdBeginRenderPass,
flink:vkCmdBeginRenderPass2KHR, and slink:VkRenderPassBeginInfo
discovered while adding `VK_KHR_create_renderpass2` to the validation
layers.

* 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.
* Update release number to 91.
Public Issues:
* Update Ubuntu subsystem build instructions in `BUILD.adoc` (public pull
request 624).
* Delete the `VK_KHR_mir_surface` extension from the Specification and
XML, due to EOL of the only driver known to have supported it, and
near-EOL of Mir itself (public issue 814).
* Fix options for some figures that were using old ones (public pull
request 841).
* Fix various accidentally repeated words (public pull request 843).

elink:VkDriverIdKHR type (public issue 811).
Internal Issues:
* Clarify for the <<features-features-shaderStorageImageExtendedFormats>>
feature and in the <<spirvenv-capabilities-table>> that the feature
means that all of the formats are supported, and that otherwise the
features can be queried per-format (internal issue 1273).
* Clarified interactions of `VK_EXT_external_memory_host` with host cache
management commands and structures flink:vkMapMemory,
flink:vkFlushMappedMemoryRanges, slink:VkMappedMemoryRange, and
flink:vkUnmapMemory using the new glossary term "`Host Mapped Device
Memory`" (internal issue 1385).

* Mark the <<VK_KHR_mir_surface>> extension obsolete (see public issue 814
- does not close this, however).
* Fix missing endif in Image Creation block (public issue 817).
Internal Issues:
* Clarify that the compressed texture formats corresponding to
<<features-features-textureCompressionETC2>>,
<<features-features-textureCompressionASTC_LDR>>, and
<<features-features-textureCompressionBC>> is not contingent on the
feature bits, and may be supported even if the features are not enabled
(internal issue 663).
* Clarify that code:FragStencilRefEXT is output only in the
<<interfaces-builtin-variables, Built-In Variables>> section (internal
issue 1173).
* Identify and correct many overly-aggressive uses of "`undefined`", and
narrow them down, where straightforward to do so. Mark such resolved
uses of "`undefined`" with the custom undefined: macro. Add a new
<<writing-undefined, Describing Undefined Behavior>> section (internal
issue 1267).
* Don't require code:inline_uniform_block descriptors to be populated
before use in the flink:vkAllocateDescriptorSets section (internal issue
1380).
* Allow suppressing inline SVG images by controlling this with an
attribute set in the Makefile, rather than the explicit [%inline]
directive (internal issue 1391).
* Mark 'Khronos' as a registered trademark in several places, now that it
is one.
* Fix typo in the <<VK_KHR_shader_atomic_int64>> appendix using the GLSL

slink:VkSampleLocationsInfoEXT::pname:sampleLocationsCount optional, to
fix bogus implicit valid usage checks that were causing failures in the
conformance tests.
* Fix vendor tag in reserved extension 237 constants. Does not affect
anything since it's just a placeholder, but this should avoid further
comments.
* Minor markup fixes in some extension appendices.

were reverted at some point (public pull request 724).
* Fix undefined format valid usage statements for slink:VkImageCreateInfo
in the presence of the
`VK_ANDROID_external_memory_android_hardware_buffer` extension (public

specification (internal issue 739).
* Change the value of the
pname:maxDescriptorSetUpdateAfterBindUniformBuffers minimum limit to 72
(6 times pname:maxPerStageDescriptorUpdateAfterBindUniformBuffers) in
the <<features-limits-required, Required Limits>> table (internal issue
1300).
Other Issues:
* Fix link to resource image view compatibility table in the valid usage
statements for slink:VkImageFormatListCreateInfoKHR (internal pull
request 2711).
* Update release number to 75.
Github Issues:
* Use Github handles (e.g. @handle) for contact information in vk.xml,
when available (partial fix for public issue 630).
* Add size invariance guarantee to slink:VkMemoryRequirements for
buffer/image memory requirements (public issue 661).

* Fix some duplicate words and some misspelled "`stagess`" (public pull
request 712)
Internal Issues:
* Enable continuous integration tests on the internal Khronos gitlab
server by adding a .gitlab-ci.yml file. Note: this does not implement CI
on the public Github repository (internal issue 408).
* Add link from description of depth clamping in the <<fragops-depth,
depth test>> section to the
slink:VkPipelineRasterizationStateCreateInfo::pname:depthClampEnable
parameter which enables it, making it easily searchable / findable
(internal issue 1125).
* Clarify that arrays of arrays of descriptors are not allowed in the
<<interfaces-resources-descset, Descriptor Set Interface>> and
<<interfaces-resources-setandbinding, DescriptorSet and Binding
Assignment>> sections (internal issue 1192).
* Comment out some redundant nested asciidoctor conditionals in the
slink:VkImageViewCreateInfo valid usage block, and explain in all cases
why the redundant conditional exist and are commented out (internal
issue 1231).
* Move a valid usage statement from slink:VkCommandPoolCreateInfo to the
parent flink:vkCreateCommandPool, where the device queue is known
(internal issue 1233).
* Add new slink:VkBaseInStructure and slink:VkBaseOutStructure types which
can be used by extensions and implementations for handling Vulkan
sType/pNext style structures in a more generic way (internal issue
1265).
* Clarify that
slink:VkAndroidHardwareBufferFormatPropertiesANDROID::pname:formatFeatures
only applies to external-format images. Add references to this in valid
usage statements that previously only referred to
slink:VkFormatProperties (internal issue 1244).
* Fix the description of elink:VkPipelineCreateFlagBits enumerant
ename:VK_PIPELINE_CREATE_VIEW_INDEX_FROM_DEVICE_INDEX_BIT to match the
name (internal issue 1279).
* Add a NOTE to the <<interfaces-resources-setandbinding, DescriptorSet
and Binding Assignment>> section making it clear that variables sharing
a storage class may use identical descriptor set and bindings.
Specifically state the sometimes misunderstood ability to have one or
more differently typed image descriptors sharing a descriptor set and
binding (internal SPIR-V issue 264).
* Make DynamicIndexing features and capabilities also control the
uniformity of the descriptor used in memory access instructions in the
<<interfaces-resources-descset, Descriptor Set Interface>> section. This
makes them also apply to variable_pointer usage, which can bypass the
array indexing operation (internal SPIR-V issue 289).
Other Issues:
* Correct flink:vkCmdBlitImage limitations on cubic blits to be 2D only,
not 3D.
* Update valid usage statements for slink:VkRenderPassCreateInfo and
slink:VkInputAttachmentAspectReference.

slink:VkWriteDescriptorSet, where all needed information is known, and
remove redundant statements.
* Move SPIR-V restriction that images be of either sampled or storage
types from the <<interfaces-resources-descset, Descriptor Set
Interface>> section to the <<spirvenv-module-validation, Validation
Rules within a Module>> section of the SPIR-V appendix.
* Update release number to 72.
Github Issues:
* Restructure the repository to put the specification `Makefile` and
associated spec source material at the top level, `vk.xml` and
associated scripts material in `xml/`, and generated include and source
files in `include/vulkan/` and `src/ext_loader/`, respectively (public
issue 436).
* Add missing bullet point markup to flink:vkCmdCopyImage valid usage
statement, so it gets a VUID assigned (public issue 627).
* Fix broken links in a couple of extension appendices (public pull
request 665).
* Add the \<platform> tag to the index in section 4.1 of the registry
schema documentation, and add the protect= attribute of \<extension>
tags to the comments in `registry.rnc` (public issues 673, 678).
* Add missing valid usage statements for sparse image interactions to
flink:VkImageCreateInfo (public pull request 675).
* Fix improper usage and grammar of "`can: not`" (public pull request
681).
* Remove duplicate spec language and NOTE on present layout between the
flink:vkAcquireNextImageKHR and flink:vkAcquireNextImage2KHR commands
(public pull request 685).
* Fix some typos and markup issues (public pull request 689; public issues
642, 667, 687).
* Fix typo etext:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_FENCE_FD_BIT ->
ename:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_SYNC_FD_BIT in the
<<external-semaphore-handle-types-compatibility, External semaphore
handle types compatibility>> table (public pull request 691).
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).
Other Issues:
* Fixed a minor problem with the valid usage statement extraction script,
and corresponding markup in the spec source.
New Extensions:
* `VK_AMD_shader_core_properties`
* `VK_EXT_descriptor_indexing`
* `VK_NV_shader_subgroup_partitioned`
associated material at the top level, vk.xml and associated material in
xml/, and generated include and source files in include/vulkan/ and
src/ext_loader/, respectively (public issue 436).
