Change log for March 24, 2017 Vulkan 1.0.45 spec update:
* Bump API patch number and header version number to 45 for this update.
Github Issues:
* Defined the lifetime of the memory pointed to by
slink:VkDisplayPropertiesKHR::pname:displayName to be equal to that of
its associated display handle (public issue 460).
* Correct several cases where the sparse memory feature name
pname:residencyNonResidentStrict was written as
pname:sparseResidencyNonResidentStrict (public issue 475).
Internal Issues:
* Fix ptext:pNext member of slink:VkPhysicalDeviceGroupPropertiesKHX to be
a non-const pointer. Properties structures return values, so the chain
should be non-const.
* Clarify definition of memory aliasing to consistently use the terms
"linear" and "non-linear" when referring to resources, and define what
those terms mean.
* Modified XML schema and implicit validity scripts to generate language
for all ptext:pNext values in a ptext:pNext chain instead of just the
top level struct, and made `noautovalidity` functional for ptext:sType
and ptext:pNext (internal issue 535).
* Add more detail for BT2020 and scRGB color spaces in
`VK_EXT_swapchain_colorspace` extension (internal issue 632).
* Add naming rules for Extension Structure Names (structures added to the
ptext:pNext chain of a base structure) to the style guide (internal
issue 706).
* Define the glossary term "ptext:pNext chain", and use it consistently in
the spec (internal issue 744).

Change log for March 17, 2017 Vulkan 1.0.44 spec update:
* 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).
* Fix validextensionstructs attributes for structures in the pname:pNext
chain for VkPresentInfoKHR, fixing implicit valid usage statements for
those structures (internal issue 740).

Change log for February 17, 2017 Vulkan 1.0.41 spec update:
* Bump API patch number and header version number to 41 for this update.
Github Issues:
* Made all uses of `NULL` vs. code:VK_NULL_HANDLE consistent (public issue
276).
* Clarify render pass compatibility in different usage scenarios (public
issues 303 and 304).
* Add valid usage statements to slink:VkFramebufferCreateInfo requiring
that the width, height, and number of layers of the framebuffer all be
nonzero (public issue 432).
* Allow `offset` and `align` in any GLSL version for the
`GL_KHR_vulkan_glsl` extension (public issue 435).
* Specify lifetime of string objects passed to the
tlink:PFN_vkDebugReportCallbackEXT user callback in the
+VK_EXT_debug_report+ extension (public issue 446).
* Fix inter-page links in multi-file reference pages (public issue 454).
Internal Issues:
* Update valid usage language for slink:VkImageCreateInfo to disallow
creating images that have ename:VK_IMAGE_USAGE_TRANSIENT_ATTACHMENT_BIT
set without other attachment usage bits
(ename:VK_IMAGE_USAGE_INPUT_ATTACHMENT_BIT,
ename:VK_IMAGE_USAGE_COLOR_ATTACHMENT_BIT, or
ename:VK_IMAGE_USAGE_DEPTH_STENCIL_ATTACHMENT_BIT) (internal issue 540).
* Disable `VK_EXT_swapchain_colorspace` extension until internal issues
640 and 661 are mutually resolved.
* Allow alternative mipmap level selection when [eq]#lambda == 0.5# during
texture <<textures-image-level-selection,Image Level(s) Selection>>
(internal issue 680).
Other Issues:
* Add a clarification to the style guide that the extension revision
number is treated as a patch number, so that changes to published
extensions should only include bug fixes and spec clarifications.

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 December 10, 2016 Vulkan 1.0.37 spec update:
* Bump API patch number and header version number to 37 for this update.
Github Issues:
* Add usability guarantees on the values returned by
flink:vkGetPhysicalDeviceSurfaceCapabilitiesKHR in the
slink:VkSurfaceCapabilitiesKHR structure and by
flink:vkGetPhysicalDeviceSurfaceFormatsKHR in the
pname:pSurfaceFormatCount parameter (public issue 385).
* Add elink:VkDebugReportObjectTypeEXT enumerants for new object types
introduced by new extensions (public issue 408).
* Add +VK_NVX_device_generated_commands+ etext:ACCESS bits and define how
they are used (public issue 415).
* Fix indentation for slink:VkDebugReportCallbackCreateInfoEXT member
descriptions (public issue 419).
Internal Issues:
* Expand requirements memory binding of non-sparse images and buffers from
the <<resources-association,Resource Memory Association>> section into
valid usage statements for all of the applicable API calls (internal
issue 508).
* Explicitly state that valid usage of flink:vkCreateImage requires that
flink:vkGetPhysicalDeviceImageFormatProperties would return
ename:VK_SUCCESS for the requested image configuration (internal issue
598).

Change log for November 25, 2016 Vulkan 1.0.35 spec update:
* Bump API patch number and header version number to 35 for this update.
Github Issues:
* Document in the <<memory-device-hostaccess,Host Access>> section that
mapping and unmapping does not invalidate or flush the mapped memory
(public issues 27, 126).
* Redefine the entire <<synchronization>> chapter in terms of consistent
and well defined terminology, that's called out at the start of the
chapter. This terminology is applied equally to all synchronization
types, including subpass dependencies, submissions, and much of the
implicit ordering stuff dotted around the spec. Key terms are laid out
in the <<synchronization-dependencies,Execution and Memory
Dependencies>> section at the top of the rewritten chapter (public
issues 128, 131, 132, 217, 299, 300, 302, 306, 322, 346, 347, 371, 407).
* Specify order of submission for batches in the
<<vkQueueSubmit,vkQueueSubmit>> and
<<vkQueueBindSparse,vkQueueBindSparse>> commands (public issue 371).
* Add valid usage statements to each of the WSI extension sections
indicating that the WSI-specific structure parameters must be valid, and
remove automatically generated valid usage statements now covered by the
manual sections (public issue 383).
* Clarify render pass compatibility for flink:vkCmdExecuteCommands (public
issue 390).
Internal Issues:
* Update +vk.xml+ to make previously explicit valid usage statements for
<<vkDebugReportMessageEXT,vkDebugReportMessageEXT>> implicit instead
(internal issue 553).
* Add valid usage statement for slink:VkCreateImageInfo preventing
creation of 1D sparse images (internal issue 573).
* Fix Python scripts to always read/write files in utf-8 encoding, and a
logic error in reflib.py which could cause a fatal error for
malstructured asciidoc (internal issues 578, 586).

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).
