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+

<<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).

Change log for August 5, 2016 Vulkan 1.0.23 spec update:
* Bump API patch number and header version number to 23 for this update.
Github Issues:
* Add explicit valid value attributes to pname:sType members in vk.xml
(public issue 34).
* Clarify usage of flink:vkGetInstanceProcAddr and
flink:vkGetDeviceProcAddr (public issue 225).
* Fix a copy-and-paste error in the description of
pname:pSwapchainImageCount saying that it was the count of ``format
pairs'' instead of ``swapchain images'' (public issue 292).
* flink:vkCmdExecuteCommandBuffers requires all command buffers to be
allocated from command pools created for the same queue family (public
issue 296).
* Remove bogus +optional+ attribute for
flink:vkEnumerateDeviceLayerProperties::pname:physicalDevice from vk.xml
(public issue 301).
* Clean up the <<resources-image-views-compatibility,image and image view
compatibility table>> reference and contents. Use full enumerant names.
Refer to pname:layerCount in the ``view parameters'' column instead of
pname:arrayLayers. Require N >= 1 for the cube array subview row, not
just arrayLayers >= 6 N (public issue 304).
* Modify description of <<resources-memory-aliasing,memory aliasing>> to
be consistent with the description of
<<resources-bufferimagegranularity,buffer image granularity>> (public
issue 307).
Internal Issues:
* Describe remaining +vk_platform.h+ macros in the <<boilerplate,API
Boilerplate>> appendix (internal issue 6).
* Clarify
<<features-features-robustBufferAccess,pname:robustBufferAccess>>
feature behavior; what memory can be accessed, how bounds checking is
performed, and allowing for vectorization (internal issue 332).
* Document markup for automatic extraction of reference pages from the
spec sources in the style guide (internal issue 395).

ename:VK_ERROR_INITIALIZAION_FAILED_KHR if the user requests mode
parameters that the specified display does not support (internal issue
411).
* Remove atomic counters (atomic_uint style) from KHR_vulkan_glsl, and
more clearly remove the subroutine keyword alongside it (internal issue
421).
* Clarify behavior of flink:vkCmdBindDescriptorSets for descriptor sets
not contained in the layout (internal issue 427).
Other Commits:
* Change the order in which members of sname:VkAttachmentDescription and

Change log for July 22, 2016 Vulkan 1.0.22 spec update:
* Bump API patch number and header version number to 22 for this update.
Github Issues:
* Translate the subpass self-dependency language into concrete
validity statements, and added a validity statement about the
restrictions on layout parameters (public issue 267).
* Add validity requirement that
slink:VkAttachmentDescription::pname:finalLayout and
slink:VkAttachmentReference::pname:layout must not be
ename:VK_IMAGE_LAYOUT_UNDEFINED or
ename:VK_IMAGE_LAYOUT_PREINITIALIZED (public issue 268).
* Clarify that slink:VkSubpassDescription::pname:pResolveAttachments
layouts are used. Make language consistent with other attachment
arrays (public issue 270).
* Changed 64-bit definition for
dname:VK_DEFINE_NON_DISPATCHABLE_HANDLE to work for x32 platform in
+vk.xml+ and the resulting +vulkan.h+ (public issue 282).
* Add missing error return code for
flink:vkEnumerateInstanceExtensionProperties and
flink:vkEnumerateDeviceExtensionProperties (public issue 285)
* Fix several cases of stext::VkStructName.memberName markup to
stext::VkStructName::pname:memberName, to match other usage in the
spec, and describe this markup in the style guide (public issue
286).
* Modified validity language generation script to avoid redundant
common ancestor language if covered by generic parent language, and
used `Both' instead of `Each' when appropriate (public issue 288).
Internal Issues:
* Add language about behavior of flink:vkAllocateDescriptorSets when
allocation fails due to fragmentation, a new error
ename:VK_ERROR_FRAGMENTED_POOL, and a Note explaining the situation
(internal issue 309).
* For the features of code:PointSize, code:ClipDistance, and
code:CullDistance, the SPIR-V capability is required to be declared
on use (read or write) rather than on decoration (internal issue
359).
* Have desktop versions of GLSL respect precision qualification
(code:mediump and code:lowp) when compiling for Vulkan. These will
get translated to SPIR-V's code:RelaxedPrecision decoration as they
do with OpenGL ES versions of GLSL (ESSL). The default precision of
all types is code:highp when using a desktop version (internal issue
360).
* Add validity statement for slink:VkImageCreateInfo specifying that
multisampled images must be two-dimensional, optimally tiled, and
with a single mipmap level (internal issue 369).
* Add validity statements to slink:VkImageViewCreateInfo disallowing
creation of images or image views with no supported features. Made
some slink:VkImageViewCreateInfo validity statements more precise
and consistent. Added a Note to the <<features,features>> chapter
about formats with no features (internal issue 371).
* Remove +manpages+ from default build targets. Nroff outputs
containing imbedded latexmath will not render properly. Fixing this
is a lot of work for limited use cases (internal issue 401).
Other Commits:
* Fix flink:vkRenderPassBeginInfo::pname:clearValueCount validity
statement to be based on attachment indices rather than the number
of cleared attachments
(Vulkan-LoaderAndValidationLayers/issues/601).
* Convert registry documentation from LaTeX to asciidoc source and
rename from +src/spec/readme.tex+ to +src/spec/registry.txt+.
* Fix lack of Oxford commas in validity language.
* Lots of cleanup of generator scripts and Makefiles to move extension
list for generator into the script arguments instead of the body of
genvk.py, and express better dependencies between XML, scripts, and
generated files.

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.

update.
Github Issues:
* Change valid usage statements intended to be "sub-points" to
be actual sub-points (public issue 66).
* Replace double negation in description of
slink:VkRenderPassBeginInfo::pname:pClearValues (based on public
merge 142).
* Cleanup minor typos in spec, ref pages and XML, including those
proposed in public pull requests 144, 150, 151, 167, 168, 181, and
186.
* Use *strict subset* in describing the partial order of memory
property types for slink:VkMemoryType, and update the style guide
accordingly (public issue 190).
* Fix various "a image" -> "an image" typos (public issue 191).
* Note in the <<fundamentals-validusage,Valid Usage>> and
<<extensions-interactions,Extension Interactions>> sections that
structures defined by extensions which may be passed in structure
chains using the ptext:pNext member must: include initial
ptext:sType and ptext:pNext members (public issue 192).
Internal Issues:
* Remove duplicate language from the description of the pname:fence
parameter to flink:vkQueueSubmit and improve validity language
(internal issue 91).
* Added documentation for "optional" attribute to XML readme.tex/pdf
(internal issue 149).

ename:VK_WHOLE_SIZE.
* Fixed and documented implementation of "validextensionstructs"
attribute. in XML processing scripts and readme.tex/pdf.
* Add missing validity statements to flink:vkResetEvent and
flink:vkCmdResetEvent.
* Fix validity for the
ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT flag.
Correct all the draw/dispatch commands to mention optimally tiled
images as well as linear tiled images, and say image VIEWS instead
of images. Add validity statement to flink:vkCmdBlitImage
* Replace the {apiname} macro with hardcoded "Vulkan", now that we've
committed to that name.
* Add the VK_AMD_rasterization_order extension to vk.xml.

Change log for April 22, 2016 Vulkan 1.0.11 spec update:
* Bump API patch number and header version number to 11 for this
update.
Github Issues:
* Clarify the WSI extension language by switching from the fuzzier
"ownership" language to more-consistent "acquire" language (public
issue 117).
* Clarify that memory barriers apply to all commands in the dependency
chains in the flink:vkGetRenderAreaGranularity command and the
<<synchronization-execution-and-memory-dependencies,Execution And
Memory Dependencies>> section (public issue 132).
* Clarify that a queue family is a set of queues in the
<<fundamentals-execmodel,Execution Model>> section (public issue
166).
* Removed requirement from valid usage language that
VkPresentInfoKHR::waitSemaphoreCount must be greater than 0 (public
issue 171).
* Fix broken internal links, describe structures consistently, use
consistent style for SPIR-V codewords, and tag normative terms that
were missing asciidoc tags (public issue 183 and ancillary
markup/normative language fixes).
* Fix typos for slink:VkPhysicalDeviceLimits member names in
slink:VkImageCreateInfo validity language (public issue 184).
Internal Issues:
* Document that the requested patch version number specified as part
of slink:VkApplicationInfo::pname:apiVersion is ignored when
creating an instance (internal issue 176).
* Clarify handling of extension structs in the
<<fundamentals-validusageValid Usage>> section (internal issue 254).
* Update required slink:VkImageFormatProperties::pname:maxMipLevels to
be limited to the maximum allowed mipmap pyramid size corresponding
to the actual maximum supported size for the format (internal issue
256).
* Modify the <<features-extentperimagetype,Allowed Extent Values Based
On Image Type>> section so the allowed maximum extent is the maximum
image dimension supported for each dimension of the type of texture
being queried (internal issue 257).
* Clarify in the <<spirvenv-module-validation,Validation Rules within
a Module>> section that at least one of the code:LocalSize execution
mode or code:WorkgroupSize decoration is required for each compute
shader entry point in a shader module (internal issue 279).
* Add validity rules for formats in flink:vkCmdClearColorImage and
flink:vkCmdClearDepthStencilImage (internal issue 283).

anywhere near that size (internal issue 284).
Other Commits:
* Fix various minor markup errors reported by validation scripts.
* Change copyright from Khronos Free Use License to Apache 2.0 license

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).

Change log for March 4, 2016 Vulkan 1.0.5 spec update:
* Bump API patch number to 5 for this update.
Github Issues:
* Correctly describe slink:VkPhysicalDeviceProperties pname:deviceName
member as a string, not a pointer to a string. Also one typo fix for
"hetereogeneous" (public issue 4).
* Replace maynot: macro with may: not, and "may: or maynot:" with
"may:" (public issue 4).
* Clarify that redundantly setting the state of a fence or event has
no effect (public issue 4).
* Minor fixes to ref pages to track descriptions of memory bits that
changed in the core spec. Fix name of a member in the description of
sname:sname:VkPipelineMultisampleStateCreateInfo (public issues 8,
13).
* Remove redundant validity statement for
sname:VkGraphicsPipelineCreateInfo::pname:stageCount (public issue
14).
* Fix typos in chapters 7-9 (public issue 14).
* Clarify the example demonstrating the behavior of
code:OpMemoryBarrier in the
<<shaders-execution-memory-ordering,shader memory acces
ordering>> section (public issue 16).
* 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).

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).

Change log for February 25, 2015 Vulkan 1.0.4 spec update:
* Bump API patch number from 3 to 4 for the first public update to the
spec. Add patch number to the spec title (this will be done
automatically from XML, later).
* Fixes for numerous editorial issues. Regularize descriptions of
variable-length array queries. Properly tag enumerants so they come
out in the right font (many were mislabeled in usage tags in vk.xml,
or not tagged). Spelling and markup corrections (public issue 4).
* Fix typos and clearly separate description of different types of
memory areas (public issue 5).
* Use standards-compliant preprocessor guard symbols on headers
(public issue 7).
* Note that Github users can't currently set labels on issues, and
recommend a fallback approach (public issue 15).
* Use latexmath prefix on len= attributes (public issue 29).
* Make flink:vkCmdUpdateBuffer pname:dataSize limit consistent (public
issue 65).
* Add VK_KHR_mirror_clamp_to_edge extension to core API branch, as an
optional feature not introducing new commands or enums (internal
issue 104).
* Cleanup invariance language inherited from the GL specification to
not refer to nonexistent (GL-specific) state (internal issue 111).
* Modify the flink:vkCmdDrawIndexed pname:vertexOffset definition to
not be the "base offset within the index buffer" but rather the
"value added to the vertex index before indexing into the vertex
buffer" (internal issue 118).
* Fix drawing chapter in the "Programmable Primitive Shading" section
where it described categories of drawing commands. It referenced
flink:vkCmdDrawIndexed twice. Replace the second reference with
flink:vkCmdDrawIndexedIndirect (internal issue 119).
* Typo fixed in <<sparsememory-examples-advanced,Advanced Sparse
Resources>> sparse memory example (internal issue 122).
* Add flink:VkDisplayPlaneAlphaFlagsKHR to <require> section of
VK_KHR_display extension (internal issue 125)
* Add missing optional="false,true" to
flink:vkGetImageSparseMemoryRequirements
pname:pSparseMemoryRequirementCount parameter (internal issue 132)
* Rename ename:VK_STRUCTURE_TYPE_DEBUG_REPORT_CREATE_INFO_EXT to
ename:VK_STRUCTURE_TYPE_DEBUG_REPORT_CALLBACK_CREATE_INFO_EXT
(internal issue 133)
* Fix a handful of broken cross-references in the
<<samplers,Samplers>> chapter (internal issue 134).
* Fix "Input Attachement" GLSL example to use correct syntax (internal
issue 135).
* Update XML schema and documentation to accomodate recently added
attributes for validity. Add some introductory material describing
design choices and pointing to the public repository to file issues.
* Put include of validity in the core spec extensions chapter on its
own line, so that asciidoc is happy.
* Fix vertexOffset language to specify that it's the value added to
the vertex index before indexing into the vertex buffer, not the
base offset within the index buffer.
* Fix error in the description of flink:vkCmdNextSubpass.
