* 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).
* Add missing `returnedonly` tags for a number of returned extension
structures that can be passed in pname:pNext chains (internal issue
1515).
* Clean up and rearrange some spec language for
slink:VkRenderPassCreateInfo and slink:VkAttachmentReference.txt
(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.
As a quick workaround, the Python3-specific function time.process_time()
is conditioned to the `timeit` parameter. Indeed, if this parameter is
not set, there is no point in getting the process time anyway.

* 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).
* Update copyright dates on Khronos-copyrighted files to 2019 (internal
merge request 2980).
New Extensions:
* `VK_KHR_depth_stencil_resolve`

* `VK_EXT_memory_priority`
* `VK_EXT_validation_features`
* Update release number to 96.
Public Issues:
* Fix typo in `vk.xml` for `structextends` attribute of
slink:VkPhysicalDeviceShadingRateImagePropertiesNV (public PR 870).
* 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

flink:vkUpdateDescriptorSetWithTemplate.txt example code blocks
(internal MR 2960).
* Remove some nautovalidity="true" in `vk.xml` for NV extensions where
it's clearly wrong (internal MR 2970).
* Update release number to 95.
Public Issues:
* Fix valid usage and XML issues found in public issues 789 and 790 for
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).

`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).

code:LaunchIDNV>> and <<interfaces-builtin-variables-launchsize,
code:LaunchSizeNV>> to code:uvec3.
New Extensions:
* `VK_KHR_shader_float16_int8`
* `VK_KHR_shader_float_controls`
Fixing a few items discovered by @krOoze with the EXT_debug_utils
extension spec language validation. Namely in two issues:
Issue #789:
The problem was the manual VUs should have been applied to
the `vkSetDebugUtilsObjectNameEXT` command and not the
general `VkDebugUtilsObjectNameInfoEXT` structure.
Issue #790:
Here, we needed to remove the "noautovalidity" tag on
the XML and add the "optional" tag to `pObjects` and
`objectCount`.
* 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`
* Update release number to 93.
Public Issues:
* Add spec language for ename:VK_INDEX_TYPE_NONE_NV and fix up
slink:VkAccelerationStructureTypeNV (public issue 848).
* Add missing suffix in description of slink:VkSubpassDescription2KHR
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 ==
ename:VK_IMAGE_LAYOUT_DEPTH_STENCIL_READ_ONLY_OPTIMAL (internal issue
1408).
* Modify optimize-pdf script and Makefile to retain non-optimized original
PDF on errors (internal issue 1435).

only the listed code:BuiltIn decorations are permitted, and only when
relevante features and extensions are enabled (internal issue 1449).
* Remove some duplicated Valid Usage IDs created via cut & paste error
(internal issue 1455).
* Build HTML output for extension reference pages (internal issue 1461).
** Improve genRef.py handling of aliases defined inside other refpages.
** Emit aliases in pygenerator.py.
** Add XML noautovalidity flag for VkRenderPassCreateFlags until there
are some corresponding FlagBits defined.
** Corrected types= attribute on some refpage blocks to 'flags'
** Added refpage blocks for some missing types detected by CI tests.
* Fixed many Valid Usage statement issues in slink:VkRenderPassCreateInfo,
slink:VkSubpassDescription, slink:VkSubpassDescription2KHR,
slink:VkSubpassDependency2KHR, flink:vkCmdBeginRenderPass,
flink:vkCmdBeginRenderPass2KHR, and slink:VkRenderPassBeginInfo
discovered while adding `VK_KHR_create_renderpass2` to the validation
layers.
New Extensions:
* `VK_EXT_scalar_block_layout`
* `VK_EXT_separate_stencil_usage`
* 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.
* Update release number to 91.
Public Issues:
* Update Ubuntu subsystem build instructions in `BUILD.adoc` (public pull
request 624).
* Delete the `VK_KHR_mir_surface` extension from the Specification and
XML, due to EOL of the only driver known to have supported it, and
near-EOL of Mir itself (public issue 814).
* Fix options for some figures that were using old ones (public pull
request 841).
* Fix various accidentally repeated words (public pull request 843).
* Use `time.process_time()`, introduced in Python 3.3, in the scripts
instead of `time.clock()`, which will be removed in Python 3.8 (public
pull request 844).
Internal Issues:
* Update valid usage statements for
`VK_ANDROID_external_memory_android_hardware_buffer` in
slink:VkMemoryAllocateInfo,
slink:VkImportAndroidHardwareBufferInfoANDROID, and
flink:vkGetAndroidHardwareBufferPropertiesANDROID to actually be
verifiable (internal issue 1419).
* Update valid usage statements for
`VK_ANDROID_external_memory_android_hardware_buffer` in
slink:VkMemoryAllocateInfo, slink:VkImageCreateInfo, and
slink:VkImageViewCreateInfo to move valid usage statements in
doubly-nested bullet points up one level, accomodating limitations of
the valid usage extraction script that creates `validusage.json`
(internal issue 1434).
* Fix typo etext:VK_ACCESS_SHADING_RATE_IMAGE_BIT_NV to the correct
ename:VK_ACCESS_SHADING_RATE_IMAGE_READ_BIT_NV.
* Add missing etext:VK_STRUCTURE_TYPE_* tokens to appendices for
extensions missing them.
New Extensions:
* `VK_AMD_memory_overallocation_behavior`
* `VK_NV_ray_tracing`, replacing `VK_NVX_raytracing`
since 1.1.89; fixed now).
Change log for October 28, 2018 Vulkan 1.1.90 spec update:
* Update release number to 90.
Public Issues:
* Tag flink:vkQueueWaitIdle as `externsync` in `vk.xml` (public pull
request 815).
* Update README (public pull request 834).
* `VK_NV_framebuffer_mixed_samples` and `VK_AMD_mixed_attachment_samples`
had confusing and contradictory valid usage statements when read in the
all-extensions spec build. Change them to explicitly mention which
extension each is for (public issue Vulkan-ValidationLayers/issues/353).
Internal Issues:
* Update `COPYING.md` to clarify how externally generated Vulkan
Specifications (for translations, annotations, or other reasons) must be
copyrighted, and acknowledge the Exception Clause on the `vk.xml`
license (internal issue 1079).
* Specify that flink:vkGetPhysicalDeviceImageFormatProperties may: return
pname:maxMipLevels 1 if the format is ycbcr (internal issue 1361).
* Clarify previously underspecified language for
flink:vkCmdPushConstants::pname:pStageFlags regarding use of push
constants across multiple pipelines (internal issue 1403).
* Fix typo in XML/headers for
ename:VK_STRUCTURE_TYPE_IMAGE_DRM_FORMAT_MODIFIER_EXPLICIT_CREATE_INFO_EXT,
which was previously
etext:VK_STRUCTURE_TYPE_IMAGE_EXCPLICIT_DRM_FORMAT_MODIFIER_CREATE_INFO_EXT
(internal issue 1428).
* Fix markup of equations that were sporadically breaking the
`optimize-pdf` step of PDF generation, due (apparently) to inconsistent
treatment of unwrapped multicharacter terms by different LaTeX parsers
(internal issue 1435).
* For the <<memory-model-synchronizes-with synchronizes-with>> memory
model relation cases involving a release barrier plus relaxed atomic
write, treat the atomic as if it were a release atomic and allow the
acquire side to read from its hypothetical release sequence. This is
more consistent with how C++ defines synchronization for release fences
(internal issue cross-api/memory-model#72).
* Minor editorial changes to the <<memory-model, memory model>> appendix
based on external feedback.
* Update release number to 90.
Public Issues:
* Tag flink:vkQueueWaitIdle as `externsync` in `vk.xml` (public pull
request 815).
* Update README (public pull request 834).
* `VK_NV_framebuffer_mixed_samples` and `VK_AMD_mixed_attachment_samples`
had confusing and contradictory valid usage statements when read in the
all-extensions spec build. Change them to explicitly mention which
extension each is for (public issue Vulkan-ValidationLayers/issues/353).
Internal Issues:
* Update `COPYING.md` to clarify how externally generated Vulkan

copyrighted, and acknowledge the Exception Clause on the `vk.xml`
license (internal issue 1079).
* Specify that flink:vkGetPhysicalDeviceImageFormatProperties may: return
pname:maxMipLevels 1 if the format is ycbcr (internal issue 1361).
* Clarify previously underspecified language for
flink:vkCmdPushConstants::pname:pStageFlags regarding use of push
constants across multiple pipelines (internal issue 1403).
* Fix typo in XML/headers for
ename:VK_STRUCTURE_TYPE_IMAGE_DRM_FORMAT_MODIFIER_EXPLICIT_CREATE_INFO_EXT,
which was previously
etext:VK_STRUCTURE_TYPE_IMAGE_EXCPLICIT_DRM_FORMAT_MODIFIER_CREATE_INFO_EXT
(internal issue 1428).
* Fix markup of equations that were sporadically breaking the
`optimize-pdf` step of PDF generation, due (apparently) to inconsistent
treatment of unwrapped multicharacter terms by different LaTeX parsers
(internal issue 1435).
* For the <<memory-model-synchronizes-with synchronizes-with>> memory

write, treat the atomic as if it were a release atomic and allow the
acquire side to read from its hypothetical release sequence. This is
more consistent with how C++ defines synchronization for release fences
(internal issue cross-api/memory-model#72).
* Minor editorial changes to the <<memory-model, memory model>> appendix
based on external feedback.
- make sentence a list for lesser cognitive strain
- add references to Vulkan-Headers repo
- add reference to Vulkan-Ecosystem repo
- separate obsolete and irrelevant info from the basic info
- update directory tree
- add\convert to links (for easier navigation)
- lots of frivolous changes
* Update release number to 89.

Relationship>> table with missing types (public pull request 820).
* Miscellaneous minor markup cleanup (public pull request 822).
* Fix copy/paste bugs in the description of how implicit
availability/visibility operations for atomics/barriers are ordered in
the <<memory-model-availability-visibility-semantics, Availability and
Visibility Semantics>> section (public issue 823).
* Add missing shading_rate_image bit from mesh pipeline list in the
<<synchronization-pipeline-stages-types>> list (public issue 824).
Internal Issues:
* Clarify that only statically used members of a push constant block need
to be in the push constant range, and stop referring to block members as
"`variables`" in the <<interfaces-resources-pushconst, Push Constant
Interface>> section. This is related to
https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/340
(internal issue 1401).
* Clarify interaction between flink:vkCmdSetDeviceMask and render pass
control commands in the slink:VkDeviceGroupRenderPassBeginInfo section
(internal issue 1416).
* Miscellaneous minor markup cleanup.
* Remove types defined by `"disabled"` extensions from
validextensionstructs in the XML processing scripts, so downstream code
generators don't emit them.
