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).
* Update release number to 101.
Public Issues:
* Make clear that memory types for imported host memory must be host
visible in slink:VkMemoryHostPointerPropertiesEXT.txt (public issue
897).
* Make <<interfaces-resources-layout, WARNING block>> into a NOTE block,
per the styleguide (public pull request 916).
Internal Issues:
* Make <<textures-output-format-conversion, computation of derivatives in
non-uniform flow control>> have undefined behavior (internal issue
1367).
* Make behavior, not just values, undefined for
<<textures-layout-validation, reads from inconsistent YCbCr layouts>>
(internal issue 1366).
* Consolidate version and extension behavior documentation in the
<<extended-functionality, Extended Functionality>> appendix, While a
great deal of text was moved from other parts of the Specification into
the appendix, this just serves to simplify and make consistent
discussions of versions and extensions (internal issue 1473).
* Add limits for slink:VkPhysicalDeviceRayTracingPropertiesNV in the
<<features-limits-types, Required Limit Types>> and
<<features-limits-required, Required Limits>> tables (internal issue
1511).
* Disallow <<memory-protected-memory, indirect calls within protected
command buffers>> by adding valid usage statements for the related
indirect dispatch and draw commands (internal issue 1513).
* Add valid usage stataements to slink:VkGraphicsPipelineCreateInfo,
slink:VkSubpassDescription, slink:VkSubpassDescription2KHR,
slink:VkSubpassDescriptionDepthStencilResolveKHR, and
slink:VkImageViewCreateInfo preventing the creation of a renderpass with
attachments in formats that are not supported for rendering (internal
issue 1552).
* Qualify valid usage statements for
slink:VkAttachmentReference::pname:layout parameter so restrictions only
apply if an attachment is ename:VK_ATTACHMENT_UNUSED (internal issue
1561).
* Add valid usage statement for flink:vkCmdDrawIndirectByteCountEXT
restricting pname:vertexStride to be positive (internal issue 1566).
* Make the `VK_EXT_sample_locations` extension depend on
`VK_KHR_get_physical_device_properties2` in `vk.xml`.
* Rearrange and simplify the <<interfaces-resources-layout, block layout
rules>>.
New Extensions:
* `VK_NV_cooperative_matrix`
* `VK_EXT_depth_clip_enable` (internal issue 1485).
* Update release number to 100.
Public Issues:

request 907).
* Add missing slink:VkShaderResourceUsageAMD to the <<Vk_AMD_shader_info>>
appendix (public pull request 908).
* Fix markup for <<VK_EXT_filter_cubic>> appendix (public pull request
911).
* Fix typo "`attachment`" (public pull request 914).
* Alias the enums for `VK_IMG_filter_cubic` properly to the corresponding
`VK_EXT_filter_cubic` enums, so they appear in the corresponding
enumerated types, instead of as #defines (Vulkan-Headers issue 40).
Internal Issues:
* Remove nested conditionals in valid usage statements for
slink:VkFramebufferCreateInfo and flink:vkCmdPipelineBarrier by
duplicating statements along ifdef/ifndef paths for
VK_KHR_depth_stencil_resolve (internal issue 1527).
* Clarify allowed values of <<spirv-precision-operation, SPIR-V operations
near infinity>>. For very large results of operations the allowed range
of return values as defined in the spec didn't include the largest
finite number. In some rounding modes (eg. RTZ) the largest finite
number is the correctly rounded result, so it should be allowed.
* Require descriptor types to match in slink:VkCopyDescriptorSet.
* Update release number to 99.
Public Issues:
* Add missing pname:pMemoryHostPointerProperties description to
flink:vkGetMemoryHostPointerPropertiesEXT.txt (public pull request 896).
* Minor markup fixes (public pull request 900).
* Minor update to `khronos.css` and markup fixes (originally proposed in
public pull request 901, but done via an internal MR).
Internal Issues:
* Document restrictions on image queries for Y'CbCr formats in the
<<features-formats-requiring-sampler-ycbcr-conversion>> table as well as
for slink:sname:VkImageFormatProperties and slink:VkImageCreateInfo

refactoring, using better naming conventions, updating diagrams to use
the correct orientation, etc. (internal merge request 2968).
* Fix minor typos for slink:VkImageCreateInfo and
slink:VkImageStencilUsageCreateInfoEXT.
* Add missing documentation for tlink:VkResolveModeFlagsKHR.
* Fix extension dependency of pname:scalarBlockLayout in the
<<features-features-requirements, Feature Requirements>> section.
* Fix indexing math for shader binding table calculations in the
<<shader-binding-table-indexing-rules, Indexing Rules>> section, and use
spelling "`any-hit`" consistently.
* Reconcile valid usage statement and text for sampled image layouts in
slink:VkWriteDescriptorSet
(https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/551).
* Make SPIR-V code:OpConvertUToPtr and code:OpConvertPtrToU operations
require a 64-bit integer for physical storage buffer pointers in the
<<spirvenv-module-validation, Validation Rules within a Module>>
section.
* Update to KaTeX 10.0.

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.
* 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).

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.

* Fix typo in XML/headers for
ename:VK_STRUCTURE_TYPE_IMAGE_DRM_FORMAT_MODIFIER_EXPLICIT_CREATE_INFO_EXT,
which was previously

<<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
