* Bump API patch number and header version number to 24 for this update.
Github Issues:
* Fix type mismatch in swapchain image equivalency table (public issue
289).
* Fix a copy-and-paste error in the description of
flink:vkGetSwapchainImagesKHR::pname:pSwapchainImages, that said it
was an array of ``sname:VkSwapchainImageKHR structures'' instead of
an array of ``sname:VkImage handles'' (public issue 292).
* Specify that ename:VK_IMAGE_CREATE_CUBE_COMPATIBLE_BIT is only valid
for ename:VK_IMAGE_TYPE_2D images (public issue 293).
* Add a valid usage statement to flink:vkCmdExecuteCommands saying
that when called outside a render pass instance, the secondary
command buffers must not have been created with the
ename:VK_COMMAND_BUFFER_USAGE_RENDER_PASS_CONTINUE_BIT (public issue
297).
* Fix description of +VK_NO_STDINT_H+ in the
<<boilerplate-platform-macros,platform macros>> section (public
issue 314).
Internal Issues:
* Normalize the language for the remaining built-in variables in the
<<interfaces-builtin-variables,Built-In Variables>> section. Fix
code:FrontFacing and code:HelperInvocation, as they should be of
code:boolean type rather than code:integer (internal issue 323).
* Clarify that when ename:VK_WHOLE_SIZE is used for a buffer
descriptor range, the effective range must still be within the max
buffer range (internal issue 426).
* Clarify that command buffers and descriptor sets are allocated
rather than created. Also clarify when the recording state of a
command buffer is relevant (internal issue 434).
* Bump API patch number and header version number to 23 for this update.
Github Issues:
* Add explicit valid value attributes to pname:sType members in vk.xml
(public issue 34).
* Clarify usage of flink:vkGetInstanceProcAddr and
flink:vkGetDeviceProcAddr (public issue 225).
* Fix a copy-and-paste error in the description of
pname:pSwapchainImageCount saying that it was the count of ``format
pairs'' instead of ``swapchain images'' (public issue 292).
* flink:vkCmdExecuteCommandBuffers requires all command buffers to be
allocated from command pools created for the same queue family (public
issue 296).
* Remove bogus +optional+ attribute for
flink:vkEnumerateDeviceLayerProperties::pname:physicalDevice from vk.xml
(public issue 301).
* Clean up the <<resources-image-views-compatibility,image and image view
compatibility table>> reference and contents. Use full enumerant names.
Refer to pname:layerCount in the ``view parameters'' column instead of
pname:arrayLayers. Require N >= 1 for the cube array subview row, not
just arrayLayers >= 6 N (public issue 304).
* Modify description of <<resources-memory-aliasing,memory aliasing>> to
be consistent with the description of
<<resources-bufferimagegranularity,buffer image granularity>> (public
issue 307).
Internal Issues:
* Describe remaining +vk_platform.h+ macros in the <<boilerplate,API
Boilerplate>> appendix (internal issue 6).
* Clarify
<<features-features-robustBufferAccess,pname:robustBufferAccess>>
feature behavior; what memory can be accessed, how bounds checking is
performed, and allowing for vectorization (internal issue 332).
* Document markup for automatic extraction of reference pages from the
spec sources in the style guide (internal issue 395).
* Allow flink:vkCreateDisplayModeKHR to return
ename:VK_ERROR_INITIALIZAION_FAILED_KHR if the user requests mode
parameters that the specified display does not support (internal issue
411).
* Remove atomic counters (atomic_uint style) from KHR_vulkan_glsl, and
more clearly remove the subroutine keyword alongside it (internal issue
421).
* Clarify behavior of flink:vkCmdBindDescriptorSets for descriptor sets
not contained in the layout (internal issue 427).
Other Commits:
* Change the order in which members of sname:VkAttachmentDescription and
sname:VkPipelineInputAssemblyStateCreateInfo are described to match
their order in the structures.
* Bump API patch number and header version number to 22 for this update.
Github Issues:
* Translate the subpass self-dependency language into concrete
validity statements, and added a validity statement about the
restrictions on layout parameters (public issue 267).
* Add validity requirement that
slink:VkAttachmentDescription::pname:finalLayout and
slink:VkAttachmentReference::pname:layout must not be
ename:VK_IMAGE_LAYOUT_UNDEFINED or
ename:VK_IMAGE_LAYOUT_PREINITIALIZED (public issue 268).
* Clarify that slink:VkSubpassDescription::pname:pResolveAttachments
layouts are used. Make language consistent with other attachment
arrays (public issue 270).
* Changed 64-bit definition for
dname:VK_DEFINE_NON_DISPATCHABLE_HANDLE to work for x32 platform in
+vk.xml+ and the resulting +vulkan.h+ (public issue 282).
* Add missing error return code for
flink:vkEnumerateInstanceExtensionProperties and
flink:vkEnumerateDeviceExtensionProperties (public issue 285)
* Fix several cases of stext::VkStructName.memberName markup to
stext::VkStructName::pname:memberName, to match other usage in the
spec, and describe this markup in the style guide (public issue
286).
* Modified validity language generation script to avoid redundant
common ancestor language if covered by generic parent language, and
used `Both' instead of `Each' when appropriate (public issue 288).
Internal Issues:
* Add language about behavior of flink:vkAllocateDescriptorSets when
allocation fails due to fragmentation, a new error
ename:VK_ERROR_FRAGMENTED_POOL, and a Note explaining the situation
(internal issue 309).
* For the features of code:PointSize, code:ClipDistance, and
code:CullDistance, the SPIR-V capability is required to be declared
on use (read or write) rather than on decoration (internal issue
359).
* Have desktop versions of GLSL respect precision qualification
(code:mediump and code:lowp) when compiling for Vulkan. These will
get translated to SPIR-V's code:RelaxedPrecision decoration as they
do with OpenGL ES versions of GLSL (ESSL). The default precision of
all types is code:highp when using a desktop version (internal issue
360).
* Add validity statement for slink:VkImageCreateInfo specifying that
multisampled images must be two-dimensional, optimally tiled, and
with a single mipmap level (internal issue 369).
* Add validity statements to slink:VkImageViewCreateInfo disallowing
creation of images or image views with no supported features. Made
some slink:VkImageViewCreateInfo validity statements more precise
and consistent. Added a Note to the <<features,features>> chapter
about formats with no features (internal issue 371).
* Remove +manpages+ from default build targets. Nroff outputs
containing imbedded latexmath will not render properly. Fixing this
is a lot of work for limited use cases (internal issue 401).
Other Commits:
* Fix flink:vkRenderPassBeginInfo::pname:clearValueCount validity
statement to be based on attachment indices rather than the number
of cleared attachments
(Vulkan-LoaderAndValidationLayers/issues/601).
* Convert registry documentation from LaTeX to asciidoc source and
rename from +src/spec/readme.tex+ to +src/spec/registry.txt+.
* Fix lack of Oxford commas in validity language.
* Lots of cleanup of generator scripts and Makefiles to move extension
list for generator into the script arguments instead of the body of
genvk.py, and express better dependencies between XML, scripts, and
generated files.
* 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).
* Bump API patch number and header version number to 18 for this
update.
Github Issues:
* Added "queue operation" terminology, and modified spec to actually
use this terminology (public issue 155). The act of submitting a
piece of work to a queue now generates "operations" for the queue to
execute, including operations to wait on/signal semaphores and
fences. Synchronization waits on these operations, making execution
dependency chains more obvious for semaphores and fences (though
additional work is still needed here). These changes include:
** Overview of "queue submission" commands in chapter
<<devsandqueues-submission>>.
** Updated descriptions for fence and semaphore waits and signals in
the synchronization chapter <<synchronization-semaphores-waiting>>,
<<synchronization-semaphores-signaling>> and
<<synchronization-fences-waiting>>.
** Clarifications to semaphore and fence operation within queue
submission functions.
** New glossary terms.
** Moved device idle and queue wait idle to synchronization chapter in
order to describe them in terms of other synchronization
primitives.
** Clarifications to semaphore and fence operation allowed removal of
the "implicit ordering guarantees" section, as this information is
now wholly covered where these primitives are described.
*** The "host writes" section of this is still there for now - in its
own section. This could probably be merged into other sections
later.
*** Modified fundamentals chapter on queue ordering to make sense in
context of the new changes, and avoid duplication.
<<fundamentals-queueoperation>>
* Added "aspect" and "component" definitions to the glossary, and made
sure these terms are referenced correctly (public issue 163).
* Update valid usage for ftext:vkGet*ProcAddr to only include
conditions that must be met to get a valid result. In particular,
it's okay to call flink:vkGetDeviceProcAddr with any string and will
get a code:NULL if that string is not a core Vulkan function or an
enabled extension function (addresses but does not fully close
public issue 214).
* Change the WSI extension dependencies to refer to version 1.0 of the
Vulkan API, instead of the pre-1.0-release internal revisions
numbers (public issue 238).
* Specified that <<interfaces-fragmentoutput,undeclared fragment
shader outputs>> result in undefined values input to the blending
unit or color attachment (public issue 240).
Internal Issues:
* Better documented that the registry XML "optional" tag for values
only applies when that value is the size of an array (internal issue
335).
* Add a stronger definition for the valid usages of
VkSpecializationMapEntry.size in the
<<pipelines-specialization-constants,Specialization Constants>>
section (internal issue 345).
* Change code:OpName to code:OpDecorate (along with appropriate
syntax) for vertex shader built-ins (internal issue 368).
* Add missing ref pages (those which are not currently stubs) to
apispec.txt for the single-page version of the ref pages (internal
issue 378).
Other Commits:
* Fix example in the <<descriptorsets,Descriptor Sets>> section to use
M, N, and I, describing set, binding, and index, consistently
throughout the example code.
* Bump API patch number and header version number to 12 for this
update.
Github Issues:
* Change valid usage statements intended to be "sub-points" to
be actual sub-points (public issue 66).
* Replace double negation in description of
slink:VkRenderPassBeginInfo::pname:pClearValues (based on public
merge 142).
* Cleanup minor typos in spec, ref pages and XML, including those
proposed in public pull requests 144, 150, 151, 167, 168, 181, and
186.
* Use *strict subset* in describing the partial order of memory
property types for slink:VkMemoryType, and update the style guide
accordingly (public issue 190).
* Fix various "a image" -> "an image" typos (public issue 191).
* Note in the <<fundamentals-validusage,Valid Usage>> and
<<extensions-interactions,Extension Interactions>> sections that
structures defined by extensions which may be passed in structure
chains using the ptext:pNext member must: include initial
ptext:sType and ptext:pNext members (public issue 192).
Internal Issues:
* Remove duplicate language from the description of the pname:fence
parameter to flink:vkQueueSubmit and improve validity language
(internal issue 91).
* Added documentation for "optional" attribute to XML readme.tex/pdf
(internal issue 149).
* Clarify the host-side data validity rules and behavior of
flink:vkFlushMappedMemoryRanges and
flink:vkInvalidateMappedMemoryRanges (internal issue 266).

* Added clarification to flink:vkCmdFillBuffer regarding the use of
ename:VK_WHOLE_SIZE.
* Fixed and documented implementation of "validextensionstructs"
attribute. in XML processing scripts and readme.tex/pdf.
* Add missing validity statements to flink:vkResetEvent and
flink:vkCmdResetEvent.
* Fix validity for the
ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT flag.
Correct all the draw/dispatch commands to mention optimally tiled
images as well as linear tiled images, and say image VIEWS instead
of images. Add validity statement to flink:vkCmdBlitImage
* Replace the {apiname} macro with hardcoded "Vulkan", now that we've
committed to that name.
* Add the VK_AMD_rasterization_order extension to vk.xml.
* Bump API patch number and header version number to 11 for this
update.
Github Issues:
* Clarify the WSI extension language by switching from the fuzzier
"ownership" language to more-consistent "acquire" language (public
issue 117).
* Clarify that memory barriers apply to all commands in the dependency
chains in the flink:vkGetRenderAreaGranularity command and the
<<synchronization-execution-and-memory-dependencies,Execution And
Memory Dependencies>> section (public issue 132).
* Clarify that a queue family is a set of queues in the
<<fundamentals-execmodel,Execution Model>> section (public issue
166).
* Removed requirement from valid usage language that
VkPresentInfoKHR::waitSemaphoreCount must be greater than 0 (public
issue 171).
* Fix broken internal links, describe structures consistently, use
consistent style for SPIR-V codewords, and tag normative terms that
were missing asciidoc tags (public issue 183 and ancillary
markup/normative language fixes).
* Fix typos for slink:VkPhysicalDeviceLimits member names in
slink:VkImageCreateInfo validity language (public issue 184).
Internal Issues:
* Document that the requested patch version number specified as part
of slink:VkApplicationInfo::pname:apiVersion is ignored when
creating an instance (internal issue 176).
* Clarify handling of extension structs in the
<<fundamentals-validusageValid Usage>> section (internal issue 254).
* Update required slink:VkImageFormatProperties::pname:maxMipLevels to
be limited to the maximum allowed mipmap pyramid size corresponding
to the actual maximum supported size for the format (internal issue
256).
* Modify the <<features-extentperimagetype,Allowed Extent Values Based
On Image Type>> section so the allowed maximum extent is the maximum
image dimension supported for each dimension of the type of texture
being queried (internal issue 257).
* Clarify in the <<spirvenv-module-validation,Validation Rules within
a Module>> section that at least one of the code:LocalSize execution
mode or code:WorkgroupSize decoration is required for each compute
shader entry point in a shader module (internal issue 279).
* Add validity rules for formats in flink:vkCmdClearColorImage and
flink:vkCmdClearDepthStencilImage (internal issue 283).
* Clarify that slink:VkImageFormatProperties::pname:maxResourceSize is
an upper bound, and that it may not be possible to create an image
anywhere near that size (internal issue 284).
Other Commits:
* Fix various minor markup errors reported by validation scripts.
* Change copyright from Khronos Free Use License to Apache 2.0 license
on relevant script/XML/header files. This does not affect the
specification source copyright.
* Bump API patch number and header version number to 8 for this
update.
Github Issues:
* Specify in the validity language for flink:vkBeginCommandBuffer that
pname:commandBuffer mustnot: currently be pending execution (public
issue 96).

in the <<textures-depth-compare-operation,Depth Compare Operation>>
section (public issue 100).
* Clarify the order of descriptor update operations in the
flink:vkUpdateDescriptorSets command (public issue 115).
* Specify in the VK_KHR_swapchain extension that
flink:vkAcquireNextImageKHR's pname:semaphore and pname:fence
parameters cannot both be sname:VK_NULL_HANDLE (partly addresses,
but does not fully close, public issue 117 / internal issue 246).
* Change reference to the "lifetime" of a Vulkan command to
"duration", and define the "duration" term (public issue 135).
* Added valid usage language for slink:VkImageLayout to require both
pname:height and pname:depth to be 1 for 1D images and pname:depth
to be 1 for 2D images (public issue 137).
* Fix SPIR-V example code in the
<<descriptorsets-inputattachment,Input Attachment>> section to
properly decorate the code:InputAttachmentIndex (public issue 139).
* Fix reference to nonexistent pname:imageInfo in the description of
flink:VkWriteDescriptorSet to refer to pname:pImageInfo (public
issue 140).
Internal Issues:
* Link to the fixed-function vertex chapter from the drawing chapter
(internal issue #110)
* Fix typo in slink:VkImageCreateInfo validity language:
ptext:maxExtent.sampleCounts -> pname:sampleCounts (internal issue
249).
* Explain why the non-core token etext:VK_IMAGE_LAYOUT_PRESENT_SRC_KHR
is used in the example in the
<<synchronization-semaphores,Semaphores>> section (internal issue
251).
* Attempt to clarify in the VK_KHR_android_surface extension's
<<platformQuerySupport_android,Android Platform Support>> section
that there is no Android-specific WSI query, and why (internal issue
252).

array queries when the passed array is too short, in the
VK_KHR_display, VK_KHR_swapchain, and VK_KHR_surface extensions.
* 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
<<interfaces-iointerfaces-locations,Location Assignment>>
section (public issue 45).
* Editorial fixes for <<commandbuffer-allocation,Command Buffer
Allocation>> section (public issues 54, 59).
* Clarify behavior of depth test in the <<fragops-depth,Depth
Test>> 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 <<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).

issue 101).
* Rearrange "Missing information" references in mandatory format
tables (public issue 101).

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 <<fig-non-strict-lines,Non
strict lines>> diagram. Use more easily distinguished symbols in
tables in the <<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
<<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.
* Bump API patch number to 5 for this update.
Github Issues:
* Correctly describe slink:VkPhysicalDeviceProperties pname:deviceName
member as a string, not a pointer to a string. Also one typo fix for
"hetereogeneous" (public issue 4).
* Replace maynot: macro with may: not, and "may: or maynot:" with
"may:" (public issue 4).
* Clarify that redundantly setting the state of a fence or event has
no effect (public issue 4).
* Minor fixes to ref pages to track descriptions of memory bits that
changed in the core spec. Fix name of a member in the description of
sname:sname:VkPipelineMultisampleStateCreateInfo (public issues 8,
13).
* Remove redundant validity statement for
sname:VkGraphicsPipelineCreateInfo::pname:stageCount (public issue
14).
* Fix typos in chapters 7-9 (public issue 14).
* Clarify the example demonstrating the behavior of
code:OpMemoryBarrier in the
<<shaders-execution-memory-ordering,shader memory acces
ordering>> section (public issue 16).

the description of flink:vkFreeMemory (public issue 17).
* Forbid allocation callbacks from calling into the API in the
<<memory-allocation,memory allocation>> section (public issue
20).
* Add missing validity rules about size being greater than 0 and
offset being less than size of object. Fix
flink:VkMappedMemoryRange's misinterpretation of offset (public
issues 27, 31).
* Add validity rule disallowing overlapping source/destination
descriptors in flink:VkCopyDescriptorSet (public issue 32).
* Clarify that array and matrix stride has to be a multiple of the
base alignment of the array or matrix in the
<<interfaces-resources-layout,Offset and Stride Assignment>>
section (public issue 38).
* Correct parenthesis floor nesting error in equation for
<<textures-RGB-sexp,RGB to shared exponent conversion>>.
Clarify case of when exp' is forced to 0, avoiding log2(0) undefined
problem (public issue 40).
* Remove redundant statement from the code:FragDepth description in
the <<interfaces-builtin-variables,Built-In Variables>>
section (public issue 47).
* Define the clamping of the
<<textures-level-of-detail-operation,bias added to the scale
factor>> by linking to the slink:VkPhysicalDevice feature
pname:maxSamplerLodBias (public issue 64).
* Fix typo "optimal linear resources" and clarify the set of resources
<<features-limits-bufferImageGranularity,the
pname:bufferImageGranularity resource>> applies to (public issue
67).
* Replace 'descriptor accessed by a pipeline' language for
sname:VkDescriptorSetAllocateInfo with more precise phrasing about
binding a descriptor set before a command that invokes work using
that set (public issue 69).
* tstripadj.svg contained an Inkscape tag which caused Firefox and IE
11 to fail to render it, and was illegal SVG. Generating Plain SVG
from the Inkscape SVG source fixes this (public issue 70).
* Fix validity for sname:VkVertexInputBindingDescription and
sname:VkVertexInputAttributeDescription numbers (public issue 72).
Internal Issues:
* Clarify the meaning of
ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT in
elink:VkFormatFeatureFlagBits with respect to depth compare
(internal issue 107).
* Added a note explaining that ename:VK_QUEUE_TRANSFER_BIT may or may
not be reported for a queue family that already supports
ename:VK_QUEUE_GRAPHICS_BIT or ename:VK_QUEUE_COMPUTE_BIT as the
former is a strict subset of the latter ones (internal issue 116).
* Add validity language for sname:VkDescriptorSetAllocateInfo about
exceeding the descriptor pool capacity (internal issue 140).
* Add ename:VK_INCOMPLETE success code for
flink:vkEnumeratePhysicalDevices query (internal issue 163).

spec. Add patch number to the spec title (this will be done
automatically from XML, later).
* Fixes for numerous editorial issues. Regularize descriptions of
variable-length array queries. Properly tag enumerants so they come
out in the right font (many were mislabeled in usage tags in vk.xml,
or not tagged). Spelling and markup corrections (public issue 4).
* Fix typos and clearly separate description of different types of
memory areas (public issue 5).
* Use standards-compliant preprocessor guard symbols on headers
(public issue 7).
* Note that Github users can't currently set labels on issues, and
recommend a fallback approach (public issue 15).
* Use latexmath prefix on len= attributes (public issue 29).
* Make flink:vkCmdUpdateBuffer pname:dataSize limit consistent (public
issue 65).
* Add VK_KHR_mirror_clamp_to_edge extension to core API branch, as an
optional feature not introducing new commands or enums (internal
issue 104).
* Cleanup invariance language inherited from the GL specification to
not refer to nonexistent (GL-specific) state (internal issue 111).
* Modify the flink:vkCmdDrawIndexed pname:vertexOffset definition to
not be the "base offset within the index buffer" but rather the
"value added to the vertex index before indexing into the vertex
buffer" (internal issue 118).
* Fix drawing chapter in the "Programmable Primitive Shading" section
where it described categories of drawing commands. It referenced
flink:vkCmdDrawIndexed twice. Replace the second reference with
flink:vkCmdDrawIndexedIndirect (internal issue 119).
* Typo fixed in <<sparsememory-examples-advanced,Advanced Sparse
Resources>> sparse memory example (internal issue 122).
* Add flink:VkDisplayPlaneAlphaFlagsKHR to <require> section of
VK_KHR_display extension (internal issue 125)
* Add missing optional="false,true" to
flink:vkGetImageSparseMemoryRequirements
pname:pSparseMemoryRequirementCount parameter (internal issue 132)

ename:VK_STRUCTURE_TYPE_DEBUG_REPORT_CALLBACK_CREATE_INFO_EXT
(internal issue 133)
* Fix a handful of broken cross-references in the
<<samplers,Samplers>> chapter (internal issue 134).
* Fix "Input Attachement" GLSL example to use correct syntax (internal
issue 135).
* Update XML schema and documentation to accomodate recently added
attributes for validity. Add some introductory material describing
design choices and pointing to the public repository to file issues.
* Put include of validity in the core spec extensions chapter on its
own line, so that asciidoc is happy.
* Fix vertexOffset language to specify that it's the value added to
the vertex index before indexing into the vertex buffer, not the
base offset within the index buffer.
* Fix error in the description of flink:vkCmdNextSubpass.
