* 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`
* 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).
* 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).
* 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.
* 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).
* Implement the single-branch model as described above (internal issue
461).
