Change log for March 7, 2018 Vulkan 1.1.70 spec update:
* Vulkan 1.1 initial release. Bump API patch number and header version
number to 70 for this update. The patch number will be used for both
Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment
continuously from the previous Vulkan 1.0.69 update.
NOTE: We are not publishing an updated 1.0.70 specification, or 1.1
reference pages, along with 1.1.70. There are still minor issues to work
out with those build targets. However, we will soon generate all three
types of documents as part of the regular spec update cycle.
NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the
current specification in the `master` branch. The `1.0` branch is out of
date and will not be maintained, since we will be generating both 1.1
and 1.0 specifications from the `master` branch in the future.
Github Issues:
* Clarify how mapped memory ranges are flushed in
flink:vkFlushMappedMemoryRanges (public issue 127).
* Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a
list of tasks that each command performs, rather than necessarily being
discrete pieces of hardware that one task flows through. Add a
"`synchronization command`" pipeline type which all synchronization
command execute (it's just TOP + BOTTOM), with an explanatory note
(public issue 554).
Internal Issues:
* Regenerate all images used in the spec in Inkscape with a consistent
look-and-feel, and adjust image size attributes so they're all legible,
and not too large with respect to the spec body text (internal issue
701).
* Document in the <<extensions,extensions>> appendix and in the style
guide that `KHX` extensions are no longer supported or used in the
Vulkan 1.1 timeframe (internal issue 714).
* Remove the leftover equations_temp directory after PDF build completes
(internal issue 925).
* Update the <<credits, Credits (Informative)>> appendix to include
contributors to Vulkan 1.1, and to list them according to the API
version(s) they contributed to (internal issue 987).
* Add a NOTE to the introduction explaining that interfaces defined by
extensions which were promoted to Vulkan 1.1 are now expressed as
aliases of the Vulkan 1.1 type (internal issue 991).
* Instrument spec source conditionals so spec can be built with 1.1
features, extensions promoted to 1.1, or both (internal issues 992,
998).
* Modify the XML schema and tools to support explicit aliasing of types,
structures, and commands, and use this to express the promotion of 1.0
extensions to 1.1 core features, by making the extension interfaces
aliases of the core features they were promoted to. Mark up promoted
interfaces to allow still generating 1.0 + extension specifications
(internal issue 991).
* Platform names, along with corresponding preprocessor symbols to enable
extensions specific to those platforms, are now reserved in vk.xml using
the <platform> tag. Update the registry schema and schema specification
to match (internal issue 1011).
* Updated the <<textures-texel-replacement, Texel Replacement>> section to
clarify that reads from invalid texels for image resources result in
undefined values (internal issue 1014).
* Modify description of patch version so it continues to increment across
minor version changes (internal issue 1033).
* Clarify and unify language describing physical device-level core and
extension functionality in the <<fundamentals-validusage-extensions,
Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid
Usage for Newer Core Versions>>, <<initialization-functionpointers
Command Function Pointers>>, <<initialization-phys-dev-extensions,
Extending Physical Device From Device Extensions>>
<<extended-functionality-instance-extensions-and-devices, Instance
Extensions and Device Extensions>> sections and for
flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that
instance-level functionality is tied to the loader, and independent of
the ICD; physical device-level functionality is tied to the ICD, and
associated with device extensions; physical devices are treated more
uniformly between core and extensions; and instance and physical
versions can be different (internal issue 1048).
* Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>>
section to clarify the ability for pending command buffers to transition
to the invalid state after submission, and add a command buffer
lifecycle diagram (internal issue 1050).
* Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters
are ignored when push descriptors are not supported (internal issue
1054).
* Specify that flink:vkCreateImage will return an error if the image is
too large, in a NOTE in the slink:VkImageFormatProperties description
(internal issue 1078).
* Remove near-duplicate NOTEs about when to query function pointers
dynamically in the <<initialization, Initialization>> chapter and
replace by extending the NOTE in the <<fundamentals-abi, Application
Binary Interface>> section (internal issue 1085).
* Restore missing references to "`Sparse Resource Features`" in the
flink:VkBufferCreateFlagBits description (internal issue 1086).
* Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl`
specification, the <<descriptorsets, Resource Descriptors>> section and
its subsections, and the <<interfaces-resources-descset, Descriptor Set
Interface>> for consistency, reduction of duplicate information, and
removal of GLSL correspondance/examples (internal issue 1090).
* Correctly describe code:PrimitiveId as an Input for tessellation control
and evaluation shaders, not an Output (internal issue 1109).
* Relax the requirements on chroma offsets for nearest filtering in
<<textures-implict-reconstruction, Implicit Reconstruction>> (internal
issue 1116).
Other Issues:
* Clarify the intended relationship between specification language and
certain terms defined in the Khronos Intellectual Property Rights
policy. Specific changes include:
** Rewrote IP/Copyright preamble and introduction to better agree with
normative language both as laid out in the introduction, and the
Khronos IPR policy.
** Added notion of fully informative sections, which are now tagged with
"`(Informative)`" in their titles.
** Removed non-normative uses of the phrase "`not required`"
** Clarified the distinction between terms "`optional`" and "`not
required:`" as they relate to the IPR Policy, and updated specification
text to use terms consistent with the intent.
** Reduced additions to RFC 2119, and ensured the specification agreed
with the leaner language.
** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from
normative text.
** Moved several paragraphs that should not have been normative to
informative notes.
** Clarified a number of definitions in the Glossary.
** Updated the document writing guide to match new terminology changes.
* Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire,
application memory lifetime>> language that that for objects other than
descriptor sets, a slink:VkDescriptorSetLayout object used in the
creation of another object (such as slink:VkPipelineLayout or
slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation
of that object and can be safely destroyed afterwards.
* Updated the <<textures-scale-factor, Scale Factor Operation>> section to
use the ratio of anisotropy, rather than the integer sample rate, to
perform the LOD calculation. The spec still allows use of the sample
rate as the value used to calculate the LOD, but no longer requires it.
* Update `vulkan_ext.c` to include all platform-related definitions from
the Vulkan platform headers, following the split of the headers into
platform-specific and non-platform-specific files.
* Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter
which accidentally duplicated an anchor in the pipelines chapter. There
were no reference to this anchor, fortunately.
* Add valid usage statement for slink:VkWriteDescriptorSet and
slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout
used to allocate the source and destination sets must not have been
destroyed at the time flink:vkUpdateDescriptorSets is called.
* Document mapping of subgroup barrier functions to SPIR-V, and clarify a
place where subgroupBarrier sounds like it's execution-only in the
standalone `GL_KHR_shader_subgroup` specification.
* Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with
the default Arial font family replaced by the sans-serif Noto font
family.
* Numerous minor updates to README.adoc, build scripts, Makefiles, and
registry and style guide specifications to support Vulkan 1.1 outputs,
use them as defaults, and remove mention of `KHX` extensions, which are
no longer supported.
New Extensions:
* `VK_EXT_vertex_attrib_divisor`

Change log for February 19, 2018 Vulkan 1.0.69 spec update:
* Bump API patch number and header version number to 69 for this update.
Github Issues:
* Clean up description of synchronization for flink:vkAcquireNextImageKHR
(public issue 626).
* Move valid usage statements requiring offset and extent to respect image
transfer granularity requirements of the queue family they are submitted
against from slink:VkImageCopy and slink:VkBufferImageCopy to the
corresponding flink:vkCmdCopyImage, flink:vkCmdCopyBufferToImage, and
flink:vkCmdCopyImageToBuffer commands, where are relevant information is
known (public issue 654).
* Clarify that flink:vkGetDeviceProcAddr only supports device-level
commands (public issue 655).
Internal Issues:
* Associate each elink:VkDescriptorType with a type of descriptor, and
link to descriptions of those types (internal issue 860).
* Rework valid usage extraction script to better utilize and respond to
spec markup, and fix some spec markup accordingly (internal issues 846,
909, 945).
* Rephrase flink:vkCmdPushConstants valid usage to allow overlapping push
constant ranges in different shader stages (internal issue 1103).
* Fix problem with diff_html target in extension.rb (internal issue 1104).
* Modify valid usage statements for slink:VkClearDepthStencilValue,
slink:VkGraphicsPipelineCreateInfo, slink:VkViewport, and
flink:vkCmdSetDepthBounds, and the description of vkCmdSetDepthBias, to
clarify that clamping is applied if and only if the
`VK_EXT_depth_range_unrestricted` is not enabled (internal issue 1124),
in versions of the specification built with that extension included.
* Resolve contradictions and use of undefined "`per-sample shading`" term
in the <<primsrast-sampleshading, Sample Shading>> and
<<shaders-fragment-execution, Fragment Shader Execution>> sections; for
the <<features-features-sampleRateShading, sampleRateShading feature>>;
for code:FragCoord, code:SampleId, and code:SamplePosition; and for
slink:sname:VkPipelineMultisampleStateCreateInfo (internal issue 1134).
* Clarify the meaning of the ptext:maxDescriptorSet* limits in footnote 8
of the <<features-limits-required,Required Limits>> table (internal
issue 1139).
* Fix broken NOTE markup in slink:VkSamplerCreateInfo.txt (internal issue
1140).
* Remove extend comparison language from valid usage statement for
slink:VkImageCreateInfo, turning it into a simple validation of
pname:mipLevels against pname:maxMipLevels (internal issue 1151).
* Update valid usage statements for slink:VkImageCopy when the
`VK_KHR_maintenance1` extension is enabled to allow multi-slice 2D <->
3D copies when the pnaem:extent.depth parameter specifies the number of
layers being copied, and matches the
slink:VkImageSubresourceLayers.layerCount of the 2D image (internal
issue 1152).
* Rephrase memory / control barrier rules in the
<<spirvenv-module-validation, Validation Rules within a Module>> section
to avoid "`not use none`", which could be misconstrued to allow no
synchronization semantics, and only storage class semantics (internal
issue 1154).
Other Issues:
* Move GLSL extension specifications to the KhronosGroup/GLSL repository
on Github.
* Add missing description of ename:VK_FILTER_CUBIC_IMG enum to
slink:VkFilter.
* Update description of code:PrimitiveId in the
<<interfaces-builtin-variables,Built-In Variables>> section to clarify
its behavior.
* Disallow disjoint images from being used with dedicated-memory images in
slink:VkMemoryDedicatedAllocateInfoKHR.
* Update README to suggest older versions of "mathematical" and
"ruby-gems" packages for use on Cygwin.
* Fix typos
New Extensions:
* `VK_AMD_buffer_marker`

Github Issues:
* Fix texture lookup functions in `GL_KHR_vulkan_glsl` specification
(public pull request 363).
* Clarify the state waited semaphores are left in when a call to
flink:vkQueuePresentKHR fails (public issue 572).
* Cleanup descriptions of slink:VkObjectTablePushConstantEntryNVX and
slink:VkObjectTableDescriptorSetEntryNVX (public issue 583)
* Remove redundant flink:vkCmdSetDiscardRectangleEXT valid usage
statements (public pull 586).
* Make dynamic state array length valid usage statements implicit for
flink:vkCmdSetViewportWScalingNV, flink:vkCmdSetDiscardRectangleEXT, and
flink:vkCmdSetViewport (public pull 589).
* Clarify meaning of window extent (0,0) in slink:VkSwapchainKHR for the
Windows and X11 platforms, in their respective extensions (public issue
590).
* Allow flink:vkGetPastPresentationTimingGOOGLE to return
ename:VK_INCOMPLETE (public issue 604).
* Add synchronization valid usage statements to flink:vkAcquireNextImage
(public pull 611).
* Fix some broken external links and internal xrefs (public pull 613).
* Clean up slink:VkViewport valid usage statements in the presence or
absence of relevant extensions (public pull 623).
* Remove
ename:VK_IMAGE_LAYOUT_DEPTH_READ_ONLY_STENCIL_ATTACHMENT_OPTIMAL_KHR
token from VK_KHR_maintenance2 from the non-extension VU path for
slink:VkGraphicsPipelineCreateInfo (public issue 628).
* Miscellaneous minor markup fixes - extension name strings (public pull
631), Notes (pull 633), queue names emitted by generator scripts (pull
634), block formatting in slink:VkDescriptorUpdateTemplateEntryKHR (pull
635), ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_CUBIC_BIT_IMG (pull
641), quotes and apostrophes (pull 643),
* Miscellaneous minor grammar fixes (public pull 644).
* Fix markup macros so usage like ptext:*Src* works (public pull 647).
Internal Issues:
* Clarify in the `VK_KHR_surface` and `VK_KHR_swapchain` extensions that
parameter combinations which aren't supported for normal images are also
unsupported for presentable images, even if the parameter values are
individually supported as reported by the surface capability queries
(internal issue 1029).
* Fixed XML typo in the valid value field of the pname:sType member of
slink:VkPhysicalDeviceExternalMemoryHostPropertiesEXT (internal issue
1100).
Other Issues:
* Add memory semantics validity rules to the <<spirvenv-module-validation,
Validation Rules within a Module>> section of the SPIR-V environment
appendix, and specify that sequentiality consistency is not supported.
This forbids certain cases like "`Load+Release`" that we don't expect to
ever be meaningful.
* Document mapping of OpenGL Shading Language barriers to SPIR-V scope and
semantics in the `GL_KHR_vulkan_glsl` specification.
New Extensions:
* `VK_EXT_conservative_rasterization`

Change log for October 27, 2017 Vulkan 1.0.65 spec update:
* Bump API patch number and header version number to 65 for this update.
Github Issues:
* Replaced inaccurate "`pixel`" with "`texel`" or "`compressed texel
block`" as appropriate in the <<sparsememory, Sparse Resources>> chapter
(public issue 86).
* Attempt to clarify security/integrity guarantees in the
<<fundamentals-errors, Errors>> section (public issue 147).
* Update the <<memory-device,Device Memory>> section with clarifications
and markup fixes (public pull request 194).
* Fix typo VkDeviceCreateInfo -> slink:VkDebugMarkerObjectNameInfoEXT in
sample code for `VK_EXT_debug_marker` extension (public pull request
227).
* Clarified slink:VkFramebufferCreateInfo language regarding concurrent
use of attachment resources during a render pass instance (public issue
299).
* Added overlap rules for destination regions in <<copies,copy commands>>.
Also unified the sparse and non-sparse source-destination overlap rules,
since the non-sparse rules were technically inaccurate in the face of
aliasing in flink:vkBindMemory2 - the new rules are true regardless
(public issue 317).
* Clarified the <<features-features-samplerAnisotropy,
pname:samplerAnisotropy feature>> to only affect the
slink:VkSamplerCreateInfo::pname:anisotropyEnable value, and that
pname:maxAnisotropy is ignored when pname:anisotropyEnable is VK_FALSE
(public issue 503).
* Clarify pointer valid usage statements to use "`valid pointer to valid
_object_`" terminology and update the
<<fundamentals-validusage-pointers,Valid Usage for Pointers>> section
accordingly (public pull request 547).
* Some operations that use integer coordinates can also accept a LOD to
sample from. Add a description of that selection and the validity
conditions in the new <<textures-integer-coordinate-operations, Integer
Texel Coordinate Operations>> section (public issue 548).
* Update stext:VkImageSubresource* valid usage statements (public pull
request 550).
* Added text tying ename:VK_OUT_OF_POOL_MEMORY error for
flink:vkAllocateDescriptorSets to the number of descriptor types in the
allocating pool. Removed redundant "`length`" text about number of
descriptors returned (public issue 582).
* Update slink:VkSwapchainCreateInfoKHR descriptions (public pull request
585).
* Update slink:VkPipelineViewportWScalingStateCreateInfoNV and related
structures' valid usage statements (public pull request 587).
* Change some dates to conform to ISO 8601 as specified in the style guide
(public pull request 601).
* Fix some math markup problems and be more consistent in use of asciidoc
math markup (public pull request 602).
Internal Issues:
* Clarified that attribute reads from incomplete vertex buffer elements
are considered out of bounds accesses, in the
slink:VkPhysicalDeviceFeatures and flink:vkCmdBindVertexBuffers.txt
sections (internal issue 842).

Change log for September 15, 2017 Vulkan 1.0.61 spec update:
* Bump API patch number and header version number to 61 for this update.
Github Issues:
* Provide alternate length attributes (altlen=) in the XML schema, for
those using length attributes to generate code instead of documentation
(public issue 555).
* Fix erroneous references to `latex:` being used for asciidoc math
markup, rather than `latexmath:` (public pull request 556).
* Add author ID to XML for Kazan software renderer (public pull request
557).
Internal Issues:
* Add the <<fundamentals-abi,Application Binary Interface>> section
describing platform ABI requirements and recommendations, add examples
of function and function pointer declarations to the
<<boilerplate-platform-specific-calling-conventions, Platform-Specific
Calling Conventions>> section, and remove related language that existed
elsewhere in the specification (internal issue 64).
* Describe where to document valid usage interactions of chained
structures in the style guide, and fix one case now appearing in
slink:VkBufferCreateInfo instead of the child
slink:VkDedicatedAllocationBufferCreateInfoNV structure (internal issue
715).
* Add example to the style guide of describing enumerated types which are
empty when the spec is built without relevant extensions enabled, and
apply it to existing examples for
elink:VkDescriptorSetLayoutCreateFlagBits and
elink:VkSubpassDescriptionFlagBits (internal issue 864).
* Add a note to the <<fundamentals-validusage-enums, Valid Usage for
Enumerated Types>> section that the special values suffixed with
etext:_BEGIN_RANGE, etext:_END_RANGE, etext:_RANGE_SIZE and
etext:_MAX_ENUM are not part of the API and should: not be used by
applications (internal issue 872).
* Added note to flink:vkCmdUpdateBuffers explaining the performance
penalty for copies done in this way, and why the upper copy limit is
what it is (internal issue 952).
* Update `VK_KHX_device_group` to split some functionality into the new
`VK_KHR_bind_memory2` extension, and rename that functionality (internal
issue 969).
* Remove *Status* fields from extension appendices, since they are by
definition published and complete by the time they reach the public
github repository (internal issue 973).
Other Issues:
* Update Data Format specification dependency to version 1.2 and change
references to DF sections accordingly.
* Update XML to make the pname:pAllocator parameter of
flink:vkRegisterDeviceEventEXT and flink:vkRegisterDisplayEventEXT in
the `VK_EXT_display_control` extension as optional.
New Extensions:
* `VK_KHR_bind_memory2`
* `VK_KHR_image_format_list`
* `VK_KHR_maintenance2`
* `VK_KHR_sampler_ycbcr_conversion`

Change log for September 5, 2017 Vulkan 1.0.60 spec update:
* Bump API patch number and header version number to 60 for this update.
Github Issues:
* Document that <<queries-timestamps, Timestamp Queries>> can only be
meaningfully compared when they are written from the same queue (public
issue 216).
* Document that the `<extension>` tag `type` attribute is required for
non-disabled extensions (derived from, but does not close public issue
354).
* Clean up registry schema length attribute descriptions to be consistent
and correct (public issue 555).
Internal Issues:
* Replace as much of the hand-written extension appendix metadata as
possible with asciidoc includes generated from corresponding attributes
of +vk.xml+, and enhance the style guide to match. This avoids
inconsistencies between +vk.xml+ and the appendices, and produces a more
uniform style (internal issue 137).
* Remove the generated extDependency.{py,sh} files from the tree and
create them dynamically on demand instead, reducing merge conflicts
(internal issue 713).
* Add a prototype tool for generating in-place difference markup for
sections guarded by asciidoc conditionals, and new syntax for open
blocks to support it (internal issue 833).
* Remove unnecessary restriction of etext:*SYNC_FD_BIT_KHR external handle
types to the same physical device in the
slink:VkPhysicalDeviceIDPropertiesKHR,
flink:VkImportMemoryWin32HandleInfoKHR,
slink:VkImportFenceWin32HandleInfoKHR, slink:VkImportFenceFdInfoKHR,
slink:VkImportSemaphoreWin32HandleInfoKHR,
slink:VkImportSemaphoreFdInfoKHR
<<external-memory-handle-types-compatibility, External memory handle
types compatibility>>, <<external-semaphore-handle-types-compatibility,
External semaphore handle types compatibility>>, and
<<external-fence-handle-types-compatibility, External fence handle types
compatibility>> sections (internal issue 956).
Other Issues:
* Remove dependency of +VK_KHX_device_group+ on +VK_KHR_swapchain+ (there
is an interaction, but not a strict dependency), and add a new
`extension` attribute to the `<require` XML tag to allow classifying a
subset of interfaces of an extension as requiring another extension.
Update the registry schema and documentation accordingly.
New Extensions:
* `VK_AMD_shader_fragment_mask` (and related `GL_AMD_shader_fragment_mask`
GLSL extension)
* `VK_EXT_sample_locations`
* `VK_EXT_validation_cache`

Change log for August 19, 2017 Vulkan 1.0.59 spec update:
* Bump API patch number and header version number to 59 for this update.
Github Issues:
* Fix a few missing Implicit Valid Usage statements to indicate that a
common parent of two objects is required (public issue 497).
* Clarify render pass synchronization language for
slink:VkSubpassDependency and \<\<renderpass,render passes>> (public
issue 531).
* Rename ename:VK_STRUCTURE_TYPE_SURFACE_CAPABILITIES2_EXT to
ename:VK_STRUCTURE_TYPE_SURFACE_CAPABILITIES_2_EXT for consistency, and
add an alias for backwards compatibility (public issue 539).
Internal Issues:
* Add an explanation to the \<\<interfaces-builtin-variables-layer,
code:Layer>> description explaining that writing to invalid layers
results may or may not result in primitives being processed and fragment
shaders being run, and gives undefined results in the framebuffer
(internal issue 614)
* Add valid usage statement for slink:VkDescriptorSetLayoutBinding
requiring that input attachment descriptor bindings must not use
non-fragment stages (internal issue 933).
Other Issues:
* Makes description of pname:loadOp and pname:storeOp easier to read in
the \<\<renderpass-load-store-ops>> section.
New Extensions:

Change log for August 14, 2017 Vulkan 1.0.58 spec update:
* Bump API patch number and header version number to 58 for this update.
Github Issues:
* Update the <<interfaces-resources-descset,Descriptor Set Interface>>
section to allow multiple variables with the same descriptor set/binding
decorations, and require that all variables that are statically used
must be consistent with the pipeline layout. Allow
ename:VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER to be used with texture
and sampler variables (public issues 522, 524).
Internal Issues:
* Replace networkx package used for extension dependency generation with a
homegrown network dependency traverser (internal issue 713).
* Specify in the <<interfaces-fragmentoutput, Fragment Output Interface>>
section that if a fragment shader writes integers that cannot be
represented in the format of the colour attachment, then the result is
undefined (internal issue 893).
* Separate malformed valid usage statement for
slink:VkPipelineRasterizationStateCreateInfo into two (internal issue
918).
* Fix cases where the term 'pNext chain' is incorrectly used in reference
to functions, rather than their parameters. Replace 'pNext list' with
'pNext chain'. Fixed typo in the example code of
+VK_KHR_dedicated_allocation+ (internal issue 944).
* Fix typo in elink:VkExternalSemaphoreHandleTypeFlagBitsKHR enum
descriptions, replacing
etext:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_FENCE_FD_BIT_KHR with
ename:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_SYNC_FD_BIT_KHR, and make the
description more consistent with
VK_EXTERNAL_FENCE_HANDLE_TYPE_SYNC_FD_BIT_KHR (internal issue 950).
Other Issues:
* Clarify how pipeline stage masks affect
<<synchronization-pipeline-stages-masks, access and synchronization
scopes>>.
* Clarify that dedicated allocations do not allow aliasing in the
flink:vkBindBufferMemory and flink:vkBindImageMemory valid usage
statements.
* Correct specification of pname:dynamicCount for push_constant token in
slink:VkIndirectCommandsLayoutNVX.
New Extensions:
* `VK_EXT_shader_viewport_index_layer`

block size (public issue 342).
* Update documentation of ename:VK_PIPELINE_CREATE_ALLOW_DERIVATIVES_BIT
to explicitly mention both graphics and compute pipelines (public issue
525).
Internal Issues:
* Document that
slink:VkPhysicalDeviceLimits::pname:framebufferColorSampleCounts does
not cover integer formats (internal issue 550).
* Add a note under slink:VkImageViewCreateInfo describing how values meant
for one format can be sanitized when used via another format (internal
issue 927).
* Add valid usage statements to ftext:vkCmd* documenting that image
subresources used as attachments must not be accessed as non-attachments
in a render pass (internal issue 929).
* Remove obsolete 'validextensionstructs' attribute from +vk.xml+, the XML
schema, and the schema documentation (internal issue 946).
New Extensions:

Change log for July 15, 2017 Vulkan 1.0.55 spec update:
* Bump API patch number and header version number to 55 for this update.
Github Issues:
* Removed unintended optional parameter in +vk.xml+ from the
pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted
in the generation of an incorrect implicit valid usage clause allowing
pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is
non-zero (public issue 491).
* Add missing attribute to +vk.xml+ documenting that
slink:VkSwapchainCounterCreateInfoEXT extends
slink:VkSwapchainCreateInfo (public issue 510).
* Add const qualifier for some `VK_EXT_debug_market` extension command
parameters that were missing it (public issue 513).
* Fix definition of q and level~base~ in
<<textures-image-level-selection,Image Level(s) Selection>> (public
issue 515).
* Clarify lifetime requirement for slink:VkRenderPass objects used in
object creation (public issue 516).
* Fix link to floating/normalized fixed-point conversion from
<<interfaces-fragmentoutput,Fragment Output Interface>> (public issue
521).
Internal Issues:
* Update the style guide to include the general structure of a Vulkan
command name, the specific rule for using "`Get`" vs. "`Enumerate`" in
names, and a table of verbs commonly used in command names (spinoff of
internal issue 753).
* Clarified the behavior of automatic layout transitions in case of
attachment views that are 2D or 2D array views of 3D images. In
addition, restructured the valid usage clauses corresponding to the
members of the slink:VkImageSubresourceRange structure and added missing
valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer
members (internal issues 803, 849).
* Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a
push_constant declaration (internal issue 919).
Other Commits:
* Modify <<synchronization-framebuffer-regions, Framebuffer Region
Dependencies>> to use synchronization scope terminology.
* Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the
`VK_EXT_swapchain_colorspace` extension.
* Replace XML comments with `comment` attributes and/or tags, to enable
tools which transform the XML without loss of information.
* Replace `validextensionstructs` with `structextends`, which is tagged in
the child structure instead of the parent. This makes it slightly
simpler to add new structs to the XML, causes fewer merge conflicts, and
the information is kept localized to the extension structures where it
belongs. The old `validextensionstructs` attributes will be retained
until we're certain this doesn't cause problems with known consumers of
+vk.xml+.

Github Issues:
Internal Issues:
* Fix tessellation domain to have an upper-left origin in the
<<img-tessellation-topology-ul, tessellation toplogy image>> and related
language. CTS and all implementations were already doing this, it was
just a documentation bug that it was flipped to lower-left (internal
issue 603).
* Add a section to the style guide describing how VUID tags are changed
and removed when the corresponding Valid Usage statements are modified
(internal issue 829).
* Add explicit Valid Usage statement to
slink:VkPipelineDynamicStateCreateInfo to require that members of
pname:pDynamicStates must be unique (internal issue 851).

Change log for June 24, 2017 Vulkan 1.0.53 spec update:
* Bump API patch number and header version number to 53 for this update.
Github Issues:
Internal Issues:
* Clarify mappings of coordinates for mutable, compatible image views in
slink:VkImageViewCreateInfo (internal issue 815).
* Make ename:VK_BIND_SFR_BIT require a logical device with multiple
physical devices, so that standard sparse image block dimensions are
only required on systems that support multi-GPU (internal issue 835).
* Convert all files from use of // refBegin .. // refEnd comments to
delimit ref pages, to use of open blocks, and update style guide
accordingly (internal issue 839).
* Add valid usage for slink:VkWriteDescriptorSet when performing updates
to a ename:VK_STORAGE_IMAGE descriptor with layout
ename:VK_IMAGE_LAYOUT_GENERAL.
* Add a hack to the validity generator script to support an odd
interaction between flink:vkCmdFillBuffer and an extension (internal
issue 853).
* Remove redundant text describing slink:VkBufferCreateInfo::pname:usage,
which was already covered by implicit valid usage (internal issue 854).
* Update implicit validity generator script to properly handle the
pname:sType and pname:pNext members of "returnedonly" structures
(internal issue 874).
* Note that slink:VkApplicationInfo::pname:pApplicationName &
slink:VkApplicationInfo::pname:pEngineName are optional, and add missing
implicit valid usage statements for flink:vkDestroyInstance.
* Added missing valid usage for flink:vkCmdWriteTimestamp to require a
timestamp query pool.
* Simplify and/or split "`non-atomic`" valid usage statements.
New Extensions:
* `VK_AMD_gpu_shader_int16`
* `VK_EXT_blend_operation_advanced`
* `VK_EXT_sampler_filter_minmax`
* `VK_NV_framebuffer_mixed_samples`
-----------------------------------------------------
Note: the 1.0.52 spec wasn't published on github, so the 1.0.53 release
combines both change sets.
-----------------------------------------------------
Change log for June 13, 2017 Vulkan 1.0.52 spec update:
* Bump API patch number and header version number to 52 for this update.
Github Issues:
Internal Issues:
* Clarify behavior when non-coherent memory has
<<memory-device-unmap-does-not-flush, not been flushed before being
unmapped>> (internal issue 819).
* Fix description of code:WorkgroupSize builtin to note it decorates an
object, not a variable (internal issue 836).
* Fix asciidoc attributes so that trailing '{plus}' symbols in [eq] style
equations are rendered properly (internal issue 845).
* Add language to the "`Extension Handles, Objects, Enums, and Typedefs`"
section of the Procedures and Conventions document stating that any new
handle type requires a corresponding entry in the elink:VkObjectType
enumerated type (internal issue 856).
* Update style guide to use slink macro for Vulkan handle type names, and
define narrow conditions under which to use the *name and *text macros
instead of *link (internal issue 886).
* Add a dependency of the <<VK_KHX_device_group,VK_KHX_device_group>>
extension on VK_KHX_device_group_creation to +vk.xml+ and the extension
appendix.
* Change the copyright on Vulkan specification asciidoc *source* files to
CC-BY 4.0, and update the proprietary Khronos copyright applied to the
generated *output* formats (internal issue 327). This enables broader
re-use and modification of the Vulkan specification sources, while not
affecting the Reciprocal IP License between Vulkan Adopters and Working
Group Members.
New Extensions:
* `VK_NV_fill_rectangle`
* `VK_NV_fragment_coverage_to_color`

Change log for June 4, 2017 Vulkan 1.0.51 spec update:
* Bump API patch number and header version number to 51 for this update.
Github Issues:
* Add Valid Usage statement to flink:vkCmdResolveImage to require that
source and destination image formats match (public issue 492).
* Specify that a code:char* parameter must: be a valid null-terminated
string in the <<fundamentals-implicit-validity, implicit valid usage>>
section (public issue 494).
* Removed unnecessary VU for slink:VkPhysicalDeviceFeatures which is
covered by ename:VK_ERROR_FEATURE_NOT_PRESENT already (public issue
496).
* Clarify valid usage of pname:pQueueFamilyIndices in
slink:VkBufferCreateInfo, slink:VkImageCreateInfo, and
slink:VkSwapchainCreateInfoKHR (public issue 501).
* Document that dependencies of enabled extensions must also be enabled in
the <<extended-functionality-extensions-dependencies, Extension
Dependencies>> section (public issue 507).
Internal Issues:
* Change slink:VkMappedMemoryRange valid usage to allow pname:offset +
pname:size == size of the allocation. Also, if ename:VK_WHOLE_SIZE is
used, require the end of the mapping to be aligned to a multiple of
pname:nonCoherentAtomSize (internal issue 611).
* Add issue to `VK_KHR_win32_surface` about reusing window objects from a
different graphics API or Vulkan ICD (internal issue 639).
* Require locations on user in/out in `GL_KHR_vulkan_glsl` (internal issue
783).
* Added version info to the json validation output, and updated the schema
to match (internal issue 838).
* Restructure enumerated type descriptions separately from the command or
structure they are used in, allowing better reference page generation
(internal issue 841).
* Re-sort extension appendices to be in alphabetical order within each
author ID section.
* Fix enum naming and clarify behavior for
`VK_NVX_device_generated_commands` extension.

Change log for April 8, 2017 Vulkan 1.0.47 spec update:
* Bump API patch number and header version number to 47 for this update.
Github Issues:
* Allow <<synchronization-pipeline-barriers-subpass-self-dependencies,
self-dependencies>> (also described for slink:VkSubpassDependency) to
have earlier stages depend on later stages if all stages are
framebuffer-space (public issue 125).
* Clarify when pipeline state structures are ignored in the
slink:VkGraphicsPipelineCreateInfo strucure, when the tessellation
structure must be valid, and remove 'if `NULL`' descriptions from the
valid usage statements (public issue 445).
* Remove the obsolete "validextensionstructs" attribute for
flink:VkPresentRegionsKHR. This caused a pname:pNext valid usage
statement to be generated which wasn't consistent with what is stated in
the spec (public issue 481).
Internal Issues:
* Clarify facingness of non-polygon fragments for slink:VkStencilOpState
and in the code:FrontFacing <<interfaces-builtin-variables,built-in
variable description>>. Define 'facingness' of a fragment as a distinct
term from facingness of a polygon (internal issue 662).
* Clarify that the texture compression features (e.g.
pname:textureCompressionBC) means that all formats of that type
(<<features-features-textureCompressionASTC_LDR,ASTC>>,
<<features-features-textureCompressionETC2,ETC2>>,
<<features-features-textureCompressionBC,BC>>) are supported, and that
support for individual formats may: queried separately (internal issue
663).
* Clarify in the valid usage for slink:VkBindImageMemoryInfoKHX that each
SFR rectangle must be a multiple of the sparse block size for each
aspect, e.g. in a depth/stencil image using separate depth/stencil
planes (internal issue 721).
* Re-remove KHX variants of KHR structure types after promotion (internal
issue 762).

* Bump API patch number and header version number to 44 for this update.
Github Issues:
* Fix description of <<features-extentperimagetype, Allowed Extent Values
Based On Image Type>> (public issue 290).
* Better specify VK_DEVICE_LOST behavior around flink:vkQueueSubmit,
flink:vkWaitForFences, and flink:vkGetFenceStatus (public issue 423).
* Clarify definition of flink:vkGetQueryPoolResults::pname:queryCount
(public issue 441).
* Simplify and clean up normative language. Remove shall and replace
recommend and variants with should wherever possible (public issue 448).
* Fix all dangling internal cross-references in the 1.0-extensions
specification, and add scripts/checkXrefs to find these in the future
(public issue 456).
* Reverse order of ChangeLog.txt entries so the most recent version is
documented first (public issue 463)
* Removes "become invalid" which clashes with invalid state for command
buffers. (public issue 467)
* Disallowed pending state in spec text for vkResetCommandBuffer, matching
valid usage (public issue 468)
* Removes sentence describing invalid state "like initial state". (public
issue 469)
* Disallows begin command buffer from resetting command buffers in the
"recording" state. (public issue 470)
* Removes mention of state from description of
VK_COMMAND_POOL_CREATE_RESET_COMMAND_BUFFER_BIT (public issue 471)
* Removed extra valid usage statement in VkSubmitInfo (public issue 472)
Internal Issues:
* Clarify description of the pname:imageLayout member of
sname:VkDescriptorImageInfo.
* Fix typos where etext:VK_VIEW_TYPE* was used instead of
etext:VK_IMAGE_VIEW_TYPE.
* Removed the <<VK_KHR_display>> and <<VK_KHR_display_swapchain>> example
code from the specification and noted it has been moved to the Vulkan
SDK cube demo (internal issue 179).
* Reorder VkExternalMemoryHandleTypeFlagBitsNV description (internal issue
480).
* Clarify than an implementation is
<<fundamentals-validusage-flags,permitted to return 'undefined' bit
flags>> in a bitfield (internal issue 640).
* Break Valid Usage statements describing unrelated parameters into
separate statements, and add a style guide entry to follow this approach
(internal issue 685).
* Move valid usage statement for slink:VkImageCreateInfo from spec body to
the explicit valid usage block (internal issue 693).
* Fix typos in the descriptions of slink:VkDisplaySurfaceCreateInfoKHR,
flink:vkCreateDisplayModeKHR, and
flink:vkGetDisplayPlaneSupportedDisplaysKHR in the <<display,Presenting
Directly to Display Devices>> section (internal issue 698, 704, 716).
* Clarified that mandatory depth/stencil formats are only a requirement
for 2D images (internal issue 719).
* Clarify that variables decorated with DeviceIndex/ViewIndex must be in
the Input storage class (internal issue 733).
* Work around generator script problem with removal of Unicode literals
from Python 3.0-3.2 using `future` package (internal issue 737).
* Remove nonexistent structure type enums from vk.xml (internal issue
738).

Change log for February 27, 2017 Vulkan 1.0.42 spec update:
* Bump API patch number and header version number to 42 for this update
(the first anniversary edition).
Github Issues:
* Changed asciidoctor macros so cross-page links in the standalone
reference pages function properly (public issue 462).
Internal Issues:
* Clarified host visibility discussion for slink:VkMemoryType,
flink:vkInvalidateMappedMemoryRanges, elink:VkAccessFlagBits, and the
<<synchronization-framebuffer-regions,Framebuffer Region Dependencies>>
section, removing duplicated information and adding a central definition
in the access types section (internal issue 552).
* Change description of
slink:vkGetPhysicalDeviceSurfacePresentModesKHR::pname:pPresentModes to
return an array of values, not structures (internal issue 699).
New Extensions:
* Add a NOTE to the <<extensions,Layers & Extensions>> chapter describing
the experimental status of `KHX` extensions.
* Add new Khronos, Khronos Experimental, and vendor Vulkan extensions for
release at GDC:

Change log for February 10, 2017 Vulkan 1.0.40 spec update:
* Bump API patch number and header version number to 40 for this update.
* There is a major build change in this release. We are now using the
Ruby-based ``asciidoctor'' implementation, rather than the Python-based
``asciidoc'' implementation, to process the specification. While the
actual specification markup changes were minimal, this requires a new
set of build tools and a very different installation process, especially
because we now use an experimental direct-to-PDF backend for Asciidoctor
instead of Docbook->dblatex->PDF. It is no longer possible to build the
Specification using asciidoc. See doc/specs/vulkan/README.adoc
for some guidance on installing the new toolchain components.
* There are some minor rendering issues in the PDF output due to teething
problems with the asciidoctor toolchain, especially with mathematical
equations. We are aware of these and working on them.
Github Issues:
* Updated sample code for the <<sparsememory-examples-basic,sparse
resource binding example>> (public issue 97).
* Modify line and point clipping behavior in the
<<vertexpostproc-clipping, Primitive Clipping>> section to allow for
pop-free behavior. The ability to check for which behavior is
implemented may be added a future feature or extension (public issue
113).
* Unify the discussions of implicit ordering throughout the spec, in
particular in the new sections <<drawing-primitive-order, Primitive
Order>>, <<primrast-order, Rasterization Order>>, and
<<synchronization-implicit, Implicit Synchronization Guarantees>>; the
discussion of <<synchronization-submission-order, submission order>>;
and references elsewhere to these sections (public issue 133).
* Clarify \<\<descriptorsets-compatibility,Pipeline Layout Compatibility>>
language and introduce the term ``identically defined'' (public issue
164).
* Add a dependency to the +VK_EXT_debug_marker+ extension that's needed to
reuse the object type enum from +VK_EXT_debug_report+, and moves the
definition of that enum into +VK_EXT_debug_report+ where it should be
(public issue 409).
* Remove redundant valid usage statement from slink:VkImageBlit (public
issue 421).
* Update GL_KHR_vulkan_glsl to allow the ternary operator to result in a
specialization constant (public issue 424).
* Fix valid usage for flink:VkPipelineShaderStageCreateInfo (public issue
426).
* Correct typo in New Objects list for <<VK_EXT_debug_report>> (public
issue 447).
Internal Issues:
* Moved to asciidoctor for spec builds (internal issue 121).
* Update style guide to describe where to put new extensions-specific
asciidoc files, and what to name them (internal issue 626).
* Add src/spec/indexExt.py to autogenerate registry index entries linking
into the 1.0-extensions specification, instead of maintaining the index
manually. (internal issue 642).
* Autogenerate extension dependencies and lists of all extensions and all
KHR extensions from the "supported" attributes in +vk.xml+. Execute
+make config/extDependency.sh+ from +doc/specs/vulkan+ when a supported
extension is added to vk.xml, to regenerate the dependency script. The
consequence is that specifying a single extension to the +makeExt+
script will automatically enable all extensions it depends on as well,
and that the +makeAllExts+ and +makeKHR+ scripts do not need to be
updated when a new extension is supported (internal issue 648).
* Put extension appendices all at the same asciidoc section level, so KHR
WSI extensions show up in the HTML index (internal issue 648).
Other Issues:
* Imbed images in the generated HTML specs instead of loading them from
the images/ directory.
* Fix missing EXT in extension name
(ename:VK_EXT_SWAPCHAIN_COLOR_SPACE_EXTENSION_NAME).
* Add new +VK_EXT_SMPTE_2086_metadata+ extension.
* In the <<platformCreateSurface_xlib,Xlib Surface>> section of the
+VK_KHR_xlib_surface+ specification, add language warning users that
they always need to call code:XinitThreads.
* Use the term "presentable image" (rather than "swapchain image")
consistently in +VK_KHR_swapchain+ and related extensions, and add a
glossary term defining it.
* Relocate the valid usage for samples of
flink:vkGetPhysicalDeviceSparseImageFormatProperties2KHR::pname:pFormatInfo
to be below the flink:VkPhysicalDeviceSparseImageFormatInfo2KHR
structure.

Change log for January 23, 2017 Vulkan 1.0.39 spec update:
* Bump API patch number and header version number to 39 for this update.
Github Issues:
* Clarified that only accesses via the specified buffer/image subresource
ranges are included in the access scopes (public issue 306).
* Add missing valid usage statements for flink:vkCreateComputePipelines
and flink:vkCreateGraphicsPipelines (public issue 427).
Internal Issues:
* Add a Note to the <<invariance,Invariance>> appendix about a difference
between OpenGL and Vulkan with regards to how primitives derived from
offsets are handled (internal issue 355).
* Add the +<<VK_KHR_get_physical_device_properties2>>+,
+<<VK_KHR_maintenance1>>+, and +<<VK_KHR_shader_draw_parameters>>+
extensions (internal issue 448).
* Add the +<<VK_EXT_shader_subgroup_vote>>+ and
+<<VK_EXT_shader_subgroup_ballot>>+ extensions (internal issue 449).
* Update the texture level-of-detail equation in the
<<textures-scale-factor,Scale Factor Operation>> section to better
approximate the ellipse major and minor axes (internal issue 547).
* Forbid non-explicitly allowed uses of interface decorations in the
introduction to the <<interfaces,Shader Interfaces>> chapter (internal
issue 607).
* Replace use of MathJax with KaTeX, for improved load-time performance as
well as avoiding the scrolling-and-scrolling behavior due to MathJax
asynchronous rendering when loading at an anchor inside the spec. This
change also requires moving to HTML5 output for the spec instead of
XHTML, and there is a visible difference in that the chapter navigation
index is now in a scrollable sidebar instead of at the top of the
document. We may or may not retain the nav sidebar based on feedback
(internal issue 613).
* Improve consistency of markup and formatting in extension appendices
(internal issue 631).
Other Issues:
* Add explicit valid usage statements to slink:VkImageCopy requiring that
the source and destination layer ranges be contained in their respective
source and destination images.
* Add valid usage language for swapchain of flink:vkAcquireNextImage. If
the swapchain has been replaced, then it should not be passed to
flink:vkAcquireNextImage.
* Add a valid usage statement to flink:vkCreateImageView, that the image
must have been created with an appropriate usage bit set.
* Noted that slink:VkDisplayPresentInfoKHR is a valid extension of
slink:VkPresentInfoKHR in the <<wsi_swapchain,WSI Swapchain>> section.
* Update valid usage for flink:vkCmdSetViewport and flink:vkCmdSetScissor
to account for the multiple viewport feature. If the feature is not
enabled, the parameters for these functions have required values that
are defined in the <<features-features-multiViewport,multiple
viewports>> section of the spec but were not reflected in the valid
usage text for these functions.
* Add the +<<VK_EXT_swapchain_colorspace>>+ extension defining common
color spaces.

Change log for October 25, 2016 Vulkan 1.0.32 spec update:
* Bump API patch number and header version number to 32 for this update.
Github Issues:
* Add automatic visibility operations to the presentation engineE when
doing a queue present in flink:vkAcquireNextImageKHR. Removed all
references to MEMORY_READ that referenced WSI - they no longer make
sense (some aspects of public issues 128, 131, 132, 261, and 298).
* Document valid non-boolean +externsync+ attribute values for <param>
tags in +vk.xml+ (public issue 265).
* Add valid usage to slink:VkImageCreateInfo requiring that
pname:arrayLayers be 1 for images of type ename:VK_IMAGE_TYPE_3D
(public issue 319).
* Add missing captions to figures in the <<textures,Image Operations>>
chapter (public issue 334).
* Clarify WSI interaction with exclusive sharing mode (public issue
344).
* Added explicit language clarifying the allowed queue usage of
resources created with ename:VK_SHARING_MODE_CONCURRENT (public
issue 386).
* Require that the
slink:VkDescriptorSetLayoutCreateInfo::pname:binding members of the
pname:pBindings array passed to
flink:vkDescriptorSetLayoutCreateInfo all be distinct (public issue
391).
Internal Issues:
* Remove empty validity blocks from +vk.xml+ and suppressed broken
validity statements and added missing statements to explicit
validity. Doesn't affect output, other than some statements
appearing in another block now (internal issue 513).

Change log for October 14, 2016 Vulkan 1.0.31 spec update:
* Bump API patch number and header version number to 31 for this update.
Github Issues:
* Clarifying wording of slink:VkGraphicsPipelineCreateInfo parameters and
adding Valid Usage statements on render pass compatibility to the
<<drawing,drawing commands>> (public issue 375).
* Replace 'texel size' with 'element size', and add a definition to the
glossary (public issue 382).
* Clarify the description of ename:VK_ERROR_NATIVE_WINDOW_IN_USE_KHR to
make it accurate, but still generic (non-exhaustive). Remove two Valid
Usage statements describing error situations that will return
ename:VK_ERROR_NATIVE_WINDOW_IN_USE_KHR (public issue 387).
* Fix refBegin tag for elink:VkDebugReportFlagBitsEXT (public issue 392).
* The <<interfaces-builtin-variables,built-in variable>> code:PrimitiveId
in a fragment shader needs the code:Input storage class (public issue
393).
Internal Issues:
* Unused ({y,z} and {height,depth} for 1D, z and depth for 2D) offsets
must be 0 and unused extents must be 1. Added basic offset and extent
valid usage for slink:VkImageResolve to match that of slink:VkImageCopy
(internal issue 413).
* Describe what flink:vkGetPhysicalDeviceImageFormatProperties returns for
pname:sampleCounts when for pname:usage only includes transfer-related
flags (internal issue 478).
* Remove mention of
slink:VkPhysicalDeviceLimits::pname:maxImageArrayLayers from the valid
usage for slink:VkImageCreateInfo::pname:arrayLayers (internal issue
520).
* Tag usages of ``dynamically uniform'' as glossary terms and add a
glossary entry pointing to the SPIR-V Specification's definition of the
term (internal issue 531).

Change log for September 30, 2016 Vulkan 1.0.29 spec update:
* Bump API patch number and header version number to 29 for this update.
Github Issues:
* Remove redundant constraint on
slink:VkCommandBufferInheritanceInfo::pname:queryFlags (public issue
224).
* Fix typo and remove link in Note in the
<<extended-functionality-instance-extensions-and-devices, Instance
Extensions and Device Extensions>> section (public issue 359).
* Fix erroneous validation statement for the pname:layout member of
slink:VkComputePipelineCreateInfo (public issue 362).
Internal Issues:
* Restore long figure captions using asciidoc sidebar blocks, due to
restrictions of asciidoc syntax (internal issue 101).
* Replace most latexmath equations with comparable markup in straight
asciidoc, which significantly improves time required to fully load and
process the HTML forms of the Specification. There are known minor font
and alignment inconsistencies with MathJax and PDF rendering of
latexmath equations. Please do not file github issues about these. We
are aware of the inconsistencies and will make refinements over time,
while the performance improvements are compelling in at least some major
browsers (internal issue 313).
* Move handcoded validity statements from +vk.xml+ into the Specification
body, easing work in the single-branch model. Specify the distinction
between these explicit statements, and the implicit validity statements
inferred from vk.xml. Validity statements now appear in two blocks for
each command and structure - handcoded "Valid Usage" and the implicit
"Valid Usage (Implicit)" (internal issue 392).
* Add the +returnedonly="false"+ attribute to WSI output structures,
removing incorrectly generated implicit validity statements for
slink:VkDisplayPropertiesKHR, slink:VkDisplayPlanePropertiesKHR,
slink:VkDisplayModePropertiesKHR, slink:VkDisplayPlaneCapabilitiesKHR,
slink:VkSurfaceCapabilitiesKHR, and slink:VkSurfaceFormatKHR structures
(internal issue 486).
* Update slink:VkImageLayout to require the
ename:VK_IMAGE_USAGE_SAMPLED_BIT be set for sampled depth/stencil images
(internal issue 487).
* Use an explicit format specifier string for the date command invocation
in the +Makefile+ instead of the shorthand -R option, which doesn't work
on BSD and MaxOS X date commands (internal issue 500).
Other Issues:
* Use the terms ``allocation scope'' and ``extension scope'' instead of
just ``scope'', and add them to the glossary.

Change log for September 23, 2016 Vulkan 1.0.28 spec update:
* Bump API patch number and header version number to 28 for this update.
Github Issues:
* Minor spelling and typography cleanup, add definitions of
ename:VK_FALSE and ename:VK_TRUE as just what their names say
(public issues 220, 318, 325, 365; internal issues 451, 496)
* Clarify that the pname:maxDescriptorSet limits in the
<<features-limits-required,Required Limits>> table are n *
maxPerStage limit (where n=number of supported stages) (public issue
254).
* Minor cleanup to <<boilerplate-platform-macros,Platform-Specific
Macro Definitions>> appendix (public issue 314).
* Add valid usage statement to slink:VkPipelineLayoutCreateInfo
disallowing multiple push constant ranges for the same shader stage
(public issue 340).
* Clarify the elink:VkSharingMode description of what executing the
"same" barriers means in case of ownership transfer (public issue
347).
* Rename copyright.txt and add COPYING.md to try and reduce confusion
about applicable copyrights (public issue 350).
* Extend the table in the <<boilerplate-wsi-header, Window System-Specific
Header Control>> section to describe the external headers included when
each etext:VK_USE_PLATFORM_* macro is defined (public issue 376).
Internal Issues:
* Add "Revision History" to the PDF outputs following the table of
contents, to match HTML outputs (internal issue 43).
* Clarified that flink:vkMapMemory may fail due to virtual address
space limitations (internal issue 346).
* Add +refBody+ comment markup for ref page autoextraction when required
(internal issue 400).
* Document proper use of "mipmap" and "mip" in the style guide API
naming rules, matching the spelling rules (internal issue 471).
* Tweak the <<extensions,Layers and Extensions>> appendix to note that
the Specification may be built with arbitrary combinations of
extensions (internal issue 483).
* Remove incorrect statement allowing
slink:VkClearAttachment::pname:colorAttachment to be >=
slink:VkSubpassDescription::pname:colorAttachmentCount (internal
issue 488).
* The <<features-limits-viewportboundsrange,viewportBoundsRange>> is
expressed in terms of the pname:maxViewportDimensions but this is
actually two values. Clarify that it's based on the larger of the two
(if they differ) (internal issue 499).
Other Issues:
* Reflowed text of the entire spec using the 'reflow' Makefile gater,
to (hopefully) reduce future internal git churn as edits are made
and extensions added in return for one-time pain. This has no
perceptible change on the spec outputs but considerable changes on
the asciidoc source (internal issue 367).

Change log for September 16, 2016 Vulkan 1.0.27 spec update:
* Bump API patch number and header version number to 27 for this update.
Github Issues:
* Weaken flink:vkGetPipelineCacheData invariance conditions; previous
conditions were stronger than agreed and can't be guaranteed (public
issue 280).
* Add link to "Vulkan Loader Specification and Architecture Overview"
document to Normative References section (public issue 359).
Internal Issues:
* Be more clear in the <<interfaces-resources-layout-std140, uniform
buffer layout>> section that block offsets can be out of order
(internal issue 396).
* Document that extension authors should add support for their extensions
to the validation layers (internal issue 398).
* Clarify that the valid range of depth clear values should be limited
to the 0..1 range and that copies to depth aspect must also be in this
range (internal issue 412).
* Specify ``a'' vs. ``an'' use in the style guide (internal issue 432).
* Increase the maximum pname:nonCoherentAtomSize value in the
<<features-limits-required,Required Limits>> section from 128 to 256
(internal issue 435).
* Fix vk_platform.h for compiler errors on some Android platforms
(internal issue 441).
* Clarify that slink:VkPhysicalDeviceFeatures::pname:pEnabledFeatures ==
`NULL` disables all features, including the "required" feature
pname:robustBufferAccess (internal issue 479).
Other Issues:
* Expand style guide and make it more self-consistent.
* Use ISO 8601 date format everywhere.
* Emphasise the correct way of using
slink:VkSurfaceCapabilitiesKHR::pname:maxImageCount.
* Added +VK_EXT_validation_flags+ extension for validation flag mechanism.
* Fix an <<credits,author credit>> to include their current employer.

Change log for September 6, 2016 Vulkan 1.0.26 spec update:
* Bump API patch number and header version number to 26 for this update.
Github Issues:
* Bring sample code in the +VK_KHR_surface+ and +VK_KHR_swapchain+
extension summary appendices up to date, and note they will be replaced
with pointers to the LunarG SDK examples in the future (public issue
279).
* Add a new <<fundamentals-commandsyntax-results-lifetime,Lifetime of
Retrieved Results>> section specifying that ftext:vkGet* and
ftext:VkEnumerate* results are invariant unless otherwise specified, and
specify behavior for individual commands which are not invariant (public
issue 280).
* Remove conflicting definition of
slink:VkDisplayPlaneCapabilitiesKHR::pname:maxSrcPosition and clean up
language of the remaining definition (public issue 351).
* Fix many minor spelling errors and add rules to the style guide to
prevent recurrences (public issue 352).
Internal Issues:
* Remove redundant descriptions of the etext:VK_USE_PLATFORM_* macros from
the <<wsi,Window System Integration>> chapter in favor of the
description in the <<boilerplate-wsi-header,Window System-Specific
Header Control>> appendix (internal issue 6).
* Replace misleading 'can: be destroyed when not X' with more correct
'must: not be destroyed while X' in the
<<fundamentals-objectmodel-lifetime,Object Lifetime>> section. Disallow
destroying a pipeline layout while a command buffer using it is
recording (internal issue 241).
* Clarify that ename:VK_IMAGE_USAGE_TRANSIENT_ATTACHMENT_BIT is valid for
all images used as attachments in elink:VkImageUsageFlagBits and the
slink:VkImageLayout validity language (internal issue 320).
* Note that <<extended-functionality-layers,Layers>> may wrap object
handles, but that this is a generally discouraged. A link to additional
information in the documentation for layer authors is provided (issue
398)
* Replace the mustnot: and shouldnot: macros with equivalent must: not and
should: not to get rid of non-English words while still highlighting
normative language (internal issue 407).
* Disallow creating multisampled images with
ename:VK_IMAGE_CREATE_CUBE_COMPATIBLE_BIT in the slink:VkImageLayout
validity language and the <<features-supported-sample-counts,Supported
Sample Counts>> section (internal issue 445).
* Fix typo so that flink:vkCmdDrawIndexedIndirect is defined in terms of
flink:vkCmdDrawIndexed rather than flink:vkCmdDrawIndirect (internal
issue 446).
* Reorganize the per-extension information sections to all be in the
<<extensions,Layers & Extensions>> appendix. Also fix a typo in
+VK_IMG_filter_cubic+ which incorrectly identified it as a +KHR+
extension (internal issue 461).
Other Issues:
* Use asciidoc markup instead of latexmath to simplify diagrams in the
<<features-formats-non-packed,byte mapping tables>> for color formats.
* Fix a markup problem with the wildcarded enumerant names in a NOTE in
the <<textures-texel-replacement,Texel Replacement>> section.
* Fix missing attributes in the XML interface for
elink:VkExternalMemoryHandleTypeFlagBitsNV and
elink:VkExternalMemoryFeatureFlagBitsNV (KhronosGroup/Vulkan-Hpp issue
#25)
* Cleanup reference page builds so only core pages are built for releases.

Change log for August 26, 2016 Vulkan 1.0.25 spec update:
* Bump API patch number and header version number to 25 for this update.
* Structurally change the specification so that multiple extensions are
included in the +1.0+ git branch, and specifications will include or not
include those extensions at build time based on options passed to the
Makefile. See +doc/specs/vulkan/README.html+ and the ``Layers and
Extensions'' section of the ``Vulkan Documentation and Extensions''
document for more information on this change.
* Register and publish new extensions in the single-branch form:
** +VK_NV_external_memory_capabilities+
** +VK_NV_external_memory+
** +VK_NV_external_memory_win32+
** +VK_NV_win32_keyed_mutex+
Github Issues:
* Clarify description of GetInstanceProcAddr and GetDeviceProcAddr (public
issue 212).
* Add SPIR-V <<textures-operation-validation, instruction validation>> for
single-sampled images (public issue 316).
* Fix spelling of ``tesselation'' in a few places and note it as an
exception to the American spelling rules convention (public issue
327).
* Fix Makefile to create output directory for ``styleguide''
target (public issue 329).
* Fix numerous minor issues with incorrectly tags on enumerant names and
table titles (public issue 330).
* Generate specversion.txt date in UTC time and RFC 2822 format
(public issue 335).
* Convert link to the SPIR-V Specification for
flink:VkShaderModuleCreateInfo into an internal link to the normative
reference (public issue 336).
* Add ename:VK_ERROR_OUT_OF_MEMORY error code to
flink:vkCreateDebugReportCallbackEXT (public issue 337).
Internal Issues:
* Update style guide regarding use of code:NULL and dname:VK_NULL_HANDLE
(internal issue 393).
* Change the definition of latexmath:[$q$] in the
<<textures-image-level-selection,texture image level selection>> section
to be the index of the maximum defined level for the view, not the
number of levels in the view (internal issue 406).
* Allow developers to override dname:VK_DEFINE_NON_DISPATCHABLE_HANDLE
with their own binary-compatible definition (internal issue 439).
* Fix +vk_platform.h+ conditional logic causing compile failure with some
Android compilers (internal issue 441).

Change log for August 12, 2016 Vulkan 1.0.24 spec update:
* 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).

Change log for July 15, 2016 Vulkan 1.0.21 spec update:
* Bump API patch number and header version number to 21 for this update.
Github Issues:
* Clarify how <<features-supported-sample-counts,sample count queries>>
relate to the limits in slink:VkPhysicalDeviceLimits. (public issue
185).
* Clarify in the <<interfaces-iointerfaces,Shader Input and Output
Interfaces>> section that shader output variables have undefined values
until the shader writes to them (public issue 240).
* Specify the implicit value of image parameters that cannot be set in
slink:VkSwapchainCreateInfo::pname:flags, pname:imageType,
pname:mipLevels, pname:samples, pname:tiling, and pname:initialLayout
(public issue 243).
* Make use of code:NULL and code:VK_NULL_HANDLE consistent in the
VK_KHR_swapchain extension (public issue 276).
Internal Issues:
* Clarify that presenting an image to a display surface swapchain applies
the display surface's mode, and that destroying a display surface
swapchain may reset the display's mode, in the VK_KHR_display_swapchain
extension (internal issue 247).
* Better describe what a slink:VkSurfaceKHR is, and that creating one does
not set a mode, in the VK_KHR_display extension. This is a round-about
way of pointing out that mode setting is not covered by the extension,
but rather is performed as a side effect of presentation (internal issue
247).
* Add more valid usage statements to flink:vkQueuePresentKHR command when
the VK_KHR_display_swapchain extension is present (internal issue
247).
* Add more includes to the VK_KHR_swapchain extension to better document
interactions with VK_KHR_display_swapchain (internal issue 247).
* Clarify restrictions on location aliasing in the
<<fxvertex,Fixed-Function Vertex Processing>> section (internal issue
370).
* Add mathematical description of blitting to flink:vkCmdBlitImage, and
link it to the <<textures,Image Operations>> chapter. Use mathematical
notation for ranges of texel coordinates in the <<textures,Image
Operations>> chapter. Fixed miscellaneous validity statements for
flink:vkCmdBlit and slink:VkImageBlit (internal issue 382).
Other Commits:
* Added a valid usage rule to flink:VkGraphicsPipelineCreateInfo that the
ename:VK_PRIMITIVE_TOPOLOGY_PATCH_LIST topology must only be used when
tessellation shaders are used.
* Expand the style guide into a formal "Procedures and Conventions"
document. Add a API Naming Conventions section, move most of the API
Specification Appendix C (Layers and Extensions) content into the new
document, and define the resulting procedures as mandatory (where
relevant). This more clearly separates use vs. specification of Vulkan
APIs.
* Update vk_platform.h to handle 32-bit ARMv8 binaries.
* Various minor cleanups to the Makefile and build process.

Change log for July 10, 2016 Vulkan 1.0.20 spec update:
* 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).

Change log for July 1, 2016 Vulkan 1.0.19 spec update:
* Bump API patch number and header version number to 19 for this
update.
Github Issues:
* Clarified how flink:vkGetImageSubresourceLayout interacts with image
layouts (public issue 247).
* Remove ename:VK_IMAGE_LAYOUT_PREINITIALIZED from valid usage rule for
slink:VkImageMemoryBarrier::pname:oldLayout. It is only valid if it is
the current layout (public issue 248).
* Modify valid usage for flink:vkBindBufferMemory so implementations are
free to require a different backing memory size than the buffer size
(public issue 251).
* Clarify that filtering rules for flink:vkCmdBlitImage always apply, and
are usually no-ops if the formats are the same (public issue 253).
* Remove 'non-sparse' from description of
flink:vkGetBufferMemoryRequirements and
flink:vkGetImageMemoryRequirements (public issue 257).
* Remove ename:VK_ERROR_LAYER_NOT_PRESENT error code from
flink:vkCreateDevice (public issue 259).
* Change "must not" to "should not" in constraint on when
flink:vkAcquireNextImageKHR is called in the +VK_KHR_swapchain+ branch
(public issue 262).
* Change type of flink:vkCmdUpdateBuffer::pname:pData from
basetype:uint32_t* to basetype:void* (public issue 263).
* Change should: to must: in description of where additional segments are
placed in the <<[tessellation-tessellator-spacing,Tessellator Spacing>>
section (public issue 264).
Internal Issues:
* Normalize the language of all the compute shader built-ins in the
<<interfaces-builtin-variables,Built-in Variables>> section (internal
issue 323).
* Remove definition of presentation engine internal queue lengths
associated with ename:VK_PRESENT_MODE_FIFO_KHR and
ename:VK_PRESENT_MODE_FIFO_RELAXED_KHR in the <<Window System
Integration,wsi>> chapter (internal issue 374).
* The language of a Note was too broad, and implied that loaders for a
given OS would statically export functions for WSI extensions that
weren't relevant to (or supported on) the OS. Also, removed
"Khronos-provided" since the Android loader isn't (internal issue 380)
Other Commits:
* Add ename:VK_INCOMPLETE to list of return values for
flink:vkGetPipelineCacheData. Spec says this value is returnable, but it
wasn't listed in the error codes.
* Fix "correponds" typo in member definitions for
slink:VkSubpassDescription.

Change log for June 24, 2016 Vulkan 1.0.18 spec update:
* 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.

Change log for June 17, 2016 Vulkan 1.0.17 spec update:
* Bump API patch number and header version number to 17 for this
update.
Github Issues:
* Update description of vertex shader reuse in
<<shaders-vertex-execution>> (public issue 106).
* Simplify validity language around pname:ppEnabledExtensionNames and
pname:ppEnabledLayerNames (in the <<initialization-instances>> and
<<devsandqueues-device-creation>> sections) (public issue 214).
* Add missing validity rule to flink:vkCmdBeginRenderPass requiring
compatibility between slink:VkAttachmentDescription pname:initalLayout
members and the corresponding attached framebuffer images (public issue
233).
* Fix Unicode arrows appearing in output instead of relational operators
(public issue 239).
* Correctly describe the required number of elements for
code:TessLevelInner and code:TessLevelOuter arrays in the
<<interfaces-builtin-variables,Built-In Variables>> section as two and
four, respectively, instead of the other way around, and refer to this
section from the <<tessellation,Tessellation>> chapter (public issue
246).
Internal Issues:
* Document deprecation of ename:VK_COLORSPACE_SRGB_NONLINEAR_KHR in the
VK_KHR_surface extension branch, and of
ename:VK_STRUCTURE_TYPE_DEBUG_REPORT_CREATE_INFO_EXT in the
VK_EXT_debug_report branch (internal issue 328).
* Added language to define what a valid usage statement is and should be,
with a note about some apparent weirdnesses this might entail (internal
issue 357).
Other Commits:
* Added missing ename:VK_ERROR_DEVICE_LOST error to
flink:vkQueueBindSparse.

Change log for June 10, 2016 Vulkan 1.0.16 spec update:
* Bump API patch number and header version number to 16 for this
update.
Github Issues:
* Clarify that integer border values are meant to be 0/1, and that
integer texture lookups are sign-extended in the
<<textures-format-conversion,Format Conversion>> and
<<textures-texel-replacement,Texel Replacement>> sections (public
issue 52).
* Add logic to generate spec boilerplate without using the 'git'
command-line client, needed when building from a tarball or another
source of the Vulkan tree rather than a cloned git repo. Remove
boilerplate as part of 'clean' target (public issue 195).
* Document that color writes and clears to unused attachments have no
effect for slink:VkClearAttachment and
elink:VkColorComponentFlagBits (public issue 198).
* Fixed flink:vkCmdExecuteCommands validity statement for
sname:VkCommandBufferInheritanceInfo::pname:framebuffer. If used, it
must match the framebuffer in the current renderpass instance
(public issue 226).
* Added valid usage language to require for all functions that set
dynamic state that the currently bound graphics pipeline has the
corresponding dynamic state enabled (public issue 235).
Internal Issues:
* Clarify for flink:vkEnumerateInstanceExtensionProperties, in the
<<extended-functionality-instance-extensions-and-devices, Instance
Extensions and Device Extensions>> section, and in the
<<glossary,Glossary>> section when functionality should be exposed
as an instance extension, as a device extension, or as both
(internal issue 109).
* Place WorkgroupSize in alphabetical order in the
<<interfaces-builtin-variables,Built-in Variables>> section
(internal issue 323).
* Corrects valid usage in vkEndRenderPass to only affect primary
render passes, as secondaries may be entirely within a render pass,
and should be able to be ended (previous language disallowed that)
(internal issue 338).
* Fix relational operator from <= to >= in the
<<features-extentperimagetype,Allowed Extent Values>> section
(internal issue 343).
* Disallow recursion under SPIR-V entry points in the
<<spirvenv-module-validation,Validation Rules within a Module>>
section (internal SPIR-V issue 37).
Other Commits:
* Use standard Python ElementTree package instead of lxml.etree in
header / validation layer / include autogeneration from XML,
reducing platform dependencies.

impose range limits on pname:commandBufferCount (public issue 178).
* Fix validity language for flink:vkCmdExecuteCommands to refer to the
correct structure names (public issue 179).
* Fix two copy-and-paste errors in the WSI queries, where the wrong
term was used for what was being returned (public issue 206).
* Add a note in the documentation of
flink:vkGetPhysicalDeviceSurfaceFormatsKHR, about what it means if
ename:VK_FORMAT_UNDEFINED is returned (public issue 207).
Internal Issues:
* Clarify the usage and correct the name for the bitmask referenced in
<<queries-pipestats,Pipeline Statistics Queries>> (internal issue

VK_KHR_surface extension (public issue 174).
* Clarify use of etext:*_SIMULTANEOUS_USE_BIT for secondary command
buffers (public issue 182).
* Fix typos in VK_KHR_wayland_surface extension where code:wl_device was
used instead of code:wl_display (public issue 193).
* Replaced {apiname} with ``Vulkan'' in XML validity statements (public
issue 199).
* Fix dead links for WSI handle types (public issue 200).
*** N.b. this needs to be done in WSI branches as well ***
* Use "signaled" instead of "signalled" spelling everywhere (public issue
201).
*** N.b. this needs to be done in WSI branches as well ***
* Move readme.pdf target directory for XML schema documentation into the
target generation directory, instead of leaving it checked into the spec
source tree (public issue 203).
*** N.b. need to add generated PDF to registry index/1.0 page
* Fix duplicate 'which which' typo in description of
elink:VkCommandPoolResetFlagBits (public issue 204).
* Move the <<Programmable Primitive Shading>> section up one level, out of
the <<drawing-primitive-topologies,Primitive Topologies>> section
(public issue 209).
Internal Issues:
* Clarify in the <<pipelines-cache,Pipeline Cache>> section that
implementations should not manage the size of pipeline cache (internal
issue 192).
* Deprecate the concept of device layers and associated commands (internal
issue 255).
* Remove ename:VK_INCOMPLETE from the list of possible result codes of
flink:vkGetPhysicalDeviceSurfaceCapabilitiesKHR (internal issue 314).
* Add missing std140/std430 rule: the base alignment of a member following
a structure is a multiple of the structure's base alignment (internal
issue 321).
* Fixes naming of the single elink:VkColorSpaceKHR enum from
ename:VK_COLORSPACE_SRGB_NONLINEAR_KHR to
ename:VK_COLOR_SPACE_SRGB_NONLINEAR_KHR in XML/header and the
VK_KHR_swapchain and VK_KHR_surface extensions to match the style of the
typename (space and color are two words, not one) (internal issue 322).
* Make it clear that code:LocalInvocationID should only be applied to an
input variable and normalize the language describing
code:LocalInvocationID to the language for other compute shader
variables in the <<interfaces-builtin-variables,Built-in Variables>>
section, and add normative language (internal issue 323).
* Clarify in the <<fundamentals-returncodes,Return Codes>> section that
the result pointer may be modified for specific commands, even if a
runtime error is returned (internal issue 324).

* 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

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).

Change log for April 15, 2016 Vulkan 1.0.10 spec update:
* Bump API patch number and header version number to 10 for this
update.
Github Issues:
* Slightly tweak the <<memory-allocation,Host Memory>> allocator language
so that an application wrapping the standard C alloc/free/realloc
functions is still correct - the previous language was too strong with
regards to freeing memory. Also made certain scenarios clearer - an
implementation may now continue without error if an allocation failed
and it is able to continue correctly (public issue 21).
* Require that etext:VK_*_CREATE_SPARSE_BINDING_BIT is set when the
corresponding etext:VK_*_CREATE_SPARSE_RESIDENCY_BIT is used, in the
<<sparsememory-miptail,Mip Tail Regions>> section and related commands
flink:vkCreateBuffer and flink:vkCreateImage (public issue 84).
* Update the <<features,Features, Limits, and Formats>> chapter to clarify
interactions between optional features and dynamic state for the
pname:depthBiasClamp and pname:wideLines features (public issue 89).
* Describe the code:WorkgroupSize builtin in the
<<interfaces-builtin-variables,Built-In Variables>> section, and update
the <<compute-shaders,Compute Shaders>> section to further clarify how
to set the number of workgroups to execute in a compute shader (public
issue 145).
* Use the term *image subresource* everywhere instead of *subresource*,
except for the special case of *host-accessible subresource*, which may
be either an image subresource or buffer range (public issue 120)
* Add a note to the <<features,Features, Limits, and Formats>> section
about extensibility of structures (Public issue 165).
* Fix return code flink:vkAcquireNextImageKHR when the timeout parameter
is 0 to ename:VK_NOT_READY instead of ename:VK_TIMEOUT (public issue
170).
* Fix typo in slink:VkLayerProperties::pname:apiVersion field (public
issue 172).
Internal Issues:
* Fix a few minor internally-detected typos.
* Minor formatting tweaks to pseudocode in the <<resources,Resource
Creation>> chapter (internal issue 179).
* Fix typo in the definition of point sampling for
elink:VkCullModeFlagBits (internal issue 268).

Change log for April 8, 2016 Vulkan 1.0.9 spec update:
* Bump API patch number and header version number to 9 for this
update.
Github Issues:
* Fix memory type preorder definition and clarify example list and source
code for slink:VkMemoryRequirements and slink:VkMemoryHeap (public issue
26).
* Ensure slink:VkAllocationCallbacks are properly defined (public issue
73).
* Clarify the WSI extension language by switching from the fuzzier
"ownership" language to more-consistent "acquire" language (public issue
117).
* Add language allowing allocation and freeing of memory scoped to the
duration of any API command in the <<memory-allocation,Memory
Allocation>> section (public issue 136).
* Clarify the explicit location assignment always overrides the inherited
location in the <<interfaces-iointerfaces-locations,Location
Assignment>> section, even for the first member of a block (public issue
141).
* Fixed references to
slink:VkCommandBufferInheritanceInfo::pname:pipelineStatistics (public
issue 158).
* Fix name of slink:VkBufferCopy::pname:size field in validity language
for flink:vkCmdCopyBuffer (public issue 162).
Internal Issues:
* Update GL_KHR_vulkan_glsl specification to clarify disallowance of
spec-const arrays in initializers (internal issue 248).
* Clarify <<interfaces-iointerfaces-matching,Interface Matching>> section
to state that user-defined variable interface must match too (internal
issue 250).

Change log for March 25, 2016 Vulkan 1.0.7 spec update:
* Bump API patch number and header version number to 7 for this
update.
Github Issues:
* Fix slink:VkSpecializationMapEntry example to avoid C/C++ strict
aliasing issues (public issue 14).
* Clarify the meaning of "matching" in flink:vkCmdBindDescriptorSets
validity language (public issue 33).
* Add stub reference pages so xrefs to not-yet-written pages don't
generate 404 errors. However, the actual content of these pages
still needs to be filled in as time allows (public issue 44, but
does not close that issue out).
* Remove incorrect validity statement for
flink:vkGetImageSparseMemoryRequirements (public issue 85).
* Reword the
<<features-limits-bufferImageGranularity,bufferImageGranularity>>
feature in terms of "aliasing", and clarify that it applies to
bindings in the same memory object (public issue 90).
* Clarify the relationship of the slink:VkPhysicalDeviceLimits
pname:maxViewportDimensions and pname:viewportBoundsRange limits
(public issue 92).
* Specify sparse unbound texture replacement in the
<<textures-texel-replacement,Texel Replacement>> section
independently of robust buffer access language (public issue 100).
* Add the <<fundamentals-architecture-model,Architecture Model>>
section to explain architecture constraints Vulkan has chosen to
accept in order to enable portable and performant code (public issue
122).
* State that an object must not be destroyed until *all* (not *any*)
uses of that object have completed (public issue 123).
* Minor editorial cleanup (public issues 129, 134, 146, 148).
* Add validity language for layer and extension names to
slink:VkDeviceCreateInfo matching that used for
slink:VkInstanceCreateInfo (public issue 130).
* Clean up terminology for the case when the bits set in one bitmask
are a subset of the bits set in another bitmask (public issue 138).
* Document that input attachments are UniformConstant not Input, in
the <<interfaces-inputattachment,Fragment Input Attachment
Interface>> section (public glslang bug 169).
Internal Issues:
* Add max enum values to "flag bits" enums (internal issue #136).
* Clarify language around the various uses of the term "block" in the
<<appendix-compressedtex-bc,Block Compressed Image Formats>> section
(internal issue #202).
* Removed "expand" dependency from <enums> groups in vk.xml and added
auto-generation code in the scripts to infer it instead, to ensure
consistency. This caused renaming of sname:VkColorSpaceKHR and
sname:VkPresentModeKHR etext:BEGIN_RANGE (etc.) tokens, but those
tokens are metadata, not part of the API, and the Vulkan WG is OK
with this change. This change adds ranges to two additional enums
that were missing them due to not defining the "expand" attribute
(internal issue 217).
* Tweak makefile to generate ref page nroff (.3) files in the right
output directory, working around an a2x limitation (internal issue
223).
Other Commits:
* Add validity requirements for flink:vkCmdCopyQueryPoolResults
pname:dstBuffer parameter.
* Fix ref page build to generate .3 targets in the right output
directory.

Change log for March 10, 2016 Vulkan 1.0.6 spec update:
* 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).
* Define the flink:vkEnumerateInstanceExtensionProperties and
flink:vkEnumerateDeviceExtensionProperties pname:pLayerName
parameter to be a pointer to a null-terminated UTF-8 string (public
issue 101).
* Rearrange "Missing information" references in mandatory format
tables (public issue 101).
* Clarify that the enumerated extensions returned by
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.

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).

code:OpMemoryBarrier in the
<<shaders-execution-memory-ordering,shader memory acces
ordering>> section (public issue 16).
* Specify that freeing mapped memory implicitly unmaps the memory in
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).
Other Commits:
* Add the VK_NV_glsl_shader extension definitions to the API.
* Update GL_KHR_vulkan_glsl with 1) origin_upper_left as default 2)
specialization array constant semantics.
* Corrected/updated Data Format Specification date.

Fixes for #101 (public issue 101)
This is for people to review edits for @philiptaylor's points, but I'll probably pull equivalent changes back into the private repo and merge there before bringing it back to github in one of the (hopefully) weekly updates. [ChangeLog] This bundles up low-hanging editorial issues from public issue 101. Some items from that issue are more complex and remain to be done. There's also some related cleanup of the extensions appendix to clarify the distinction between a Vulkan API command, and the functions and function pointers corresponding to that command which may be provided by the API loader and runtime. Remaining todo from #101 : - [ ] 24.5.1 "Ab, Yb, Zb" -> "Xb, Yb, Zb". - [ ] 29.2 "explicitly enabled layers" clarification. - [ ] 30.3.3 Confusingly similar tiny circle symbols in format tables. - [ ] 30.3.3 Missing information about some formats. - [ ] C.3 Clarify or punt on "lower-case UTF-8" in FQDN layer names. |
