* 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.
* 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.
* Bump API patch number and header version number to 15 for this
update.
Github Issues:
* Fixed the <<glossary,Glossary>> entry for Fragment Input Attachment
Interface to specify code:UniformConstant storage class (public issue
156).
* Disallow lazily allocated memory for buffers in the description of
slink:VkMemoryRequirements::pname:memoryTypeBits (public issue 196).

Implementation Guidelines>> to refer to the correct feature names
(internal issue 305).
* Bump API patch number and header version number to 11 for this
update.
Github Issues:
* Clarify the WSI extension language by switching from the fuzzier
"ownership" language to more-consistent "acquire" language (public
issue 117).
* Clarify that memory barriers apply to all commands in the dependency
chains in the flink:vkGetRenderAreaGranularity command and the
<<synchronization-execution-and-memory-dependencies,Execution And
Memory Dependencies>> section (public issue 132).
* Clarify that a queue family is a set of queues in the
<<fundamentals-execmodel,Execution Model>> section (public issue
166).
* Removed requirement from valid usage language that
VkPresentInfoKHR::waitSemaphoreCount must be greater than 0 (public
issue 171).
* Fix broken internal links, describe structures consistently, use
consistent style for SPIR-V codewords, and tag normative terms that
were missing asciidoc tags (public issue 183 and ancillary
markup/normative language fixes).
* Fix typos for slink:VkPhysicalDeviceLimits member names in
slink:VkImageCreateInfo validity language (public issue 184).
Internal Issues:
* Document that the requested patch version number specified as part
of slink:VkApplicationInfo::pname:apiVersion is ignored when
creating an instance (internal issue 176).
* Clarify handling of extension structs in the
<<fundamentals-validusageValid Usage>> section (internal issue 254).
* Update required slink:VkImageFormatProperties::pname:maxMipLevels to
be limited to the maximum allowed mipmap pyramid size corresponding
to the actual maximum supported size for the format (internal issue
256).
* Modify the <<features-extentperimagetype,Allowed Extent Values Based
On Image Type>> section so the allowed maximum extent is the maximum
image dimension supported for each dimension of the type of texture
being queried (internal issue 257).
* Clarify in the <<spirvenv-module-validation,Validation Rules within
a Module>> section that at least one of the code:LocalSize execution
mode or code:WorkgroupSize decoration is required for each compute
shader entry point in a shader module (internal issue 279).
* Add validity rules for formats in flink:vkCmdClearColorImage and
flink:vkCmdClearDepthStencilImage (internal issue 283).
* Clarify that slink:VkImageFormatProperties::pname:maxResourceSize is
an upper bound, and that it may not be possible to create an image
anywhere near that size (internal issue 284).
Other Commits:
* Fix various minor markup errors reported by validation scripts.
* Change copyright from Khronos Free Use License to Apache 2.0 license
on relevant script/XML/header files. This does not affect the
specification source copyright.
* Bump API patch number and header version number to 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.
