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,

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 May 20, 2017 Vulkan 1.0.50 spec update:
* Bump API patch number and header version number to 50 for this update.
Github Issues:
* Fix numerous minor issues with the VK_EXT_debug_report extension (public
issues 478, 483, 486, 489, 490).
Internal Issues:
* Update flink:vkAllocateDescriptorSets to specify conditions under which
to return ename:VK_ERROR_FRAGMENTED_POOL or
ename:VK_ERROR_OUT_OF_POOL_MEMORY instead of
out-of-host/out-of-device-memory, and improve the
<<fundamentals-errorcodes, description of those errors (internal issue
654).
* Add a NOTE documenting that flink:vkAcquireNextImageKHR can only signal
a single semaphore, and how to deal with that when multiple physical
devices in a logical device need to wait on it (internal issue 730).
* Improve description of pname:pNext chains of
slink:VkPhysicalDeviceImageFormatInfo2KHR and
slink:VkImageFormatProperties2KHR (internal issue 814).
* Clean up math markup issues in the <<textures, Image Operations>>
chapter (internal issue 818).
* Update validusage target to use more robust code for preprocessing, by
making direct use of Asciidoctor's preprocessor. Added uniqueItems check
to JSON vu schema and add clean_validusage target (internal issue 826).
* Update style guide to prohibit writing non-self-contained (on a single
bullet point) Valid Usage statements, and modify offending Valid Usage
statements in the Specification to match, to assist with automatic
extraction for the validation layers (internal issue 828).
* Add ename:VK_VALIDATION_CHECK_SHADERS_EXT to elink:VkValidationCheckEXT
of the `VK_EXT_validation_flags` extension, to selectively disable
shader validation.
* Remove duplicate valid usage statement for slink:VkImageMemoryBarrier.
* Modify reflow.py script to place VUID tag anchors standalone on a line
following their corresponding bullet point, and reflow the spec text
accordingly (this had been pending since the initial tag deployment).

Change log for October 20, 2017 Vulkan 1.0.64 spec update:
* Bump API patch number and header version number to 64 for this update.
Github Issues:
* Add chapter name to the PDF page footer (public pull request 458).
* Fix several mistaken references to the nonexistent etext:VK_DEVICE_LOST
status to etext:VK_ERROR_DEVICE_LOST (public pull request 502).
* Fix description of the tlink:PFN_vkDebugReportCallbackEXT debug report
callback function pointer to match the validation layer behavior (public
issue 534).
* Document experimental KHX extensions and alternate vendor author IDs
also ending in X in more detail in the <<extensions, Layers &
Extensions>> appendix, the extensions section of the style guide, and
the registry schema description document (public issues 536, 580).
* Fix references to ptext:pDepthStencil to properly refer to
pname:pDepthStencilState or pname:pRasterizationState as appropriate in
the slink:VkGraphicsPipelineCreateInfo description (public issue 542).
* Fix wrong parameter name in slink:VkPipelineMultisampleStateCreateInfo
valid usage (public pull request 571).
Internal Issues:
* Update the style guide to describe how to write LaTeX math expressions
in table cells (internal issue 908).
* Define how framebuffer-local dependencies work between subpasses with
the same or different numbers of samples, in the
slink:VkSubpassDescription and <<synchronization-framebuffer-regions,
Framebuffer Region Dependencies>> sections. This clarifies which samples
in an input attachment you are allowed to access after a
framebuffer-local dependency (internal issue 915).
* Specify which storage classes can have an initializer in the
<<spirvenv-module-validation, Validation Rules within a Module>> section
(internal issue 1023).
* Use "LOD" consistently for "level-of-detail", to eliminate spelling
inconsistencies. The term is already standardized in the Glossary
(internal issue 1027).
Other Issues:
* Fix false positives in Makefile dependencies when rules fail, by
deleting partially-made targets.

Change log for May 20, 2017 Vulkan 1.0.50 spec update:
* Bump API patch number and header version number to 50 for this update.
Github Issues:
* Fix numerous minor issues with the VK_EXT_debug_report extension (public
issues 478, 483, 486, 489, 490).
Internal Issues:
* Update flink:vkAllocateDescriptorSets to specify conditions under which
to return ename:VK_ERROR_FRAGMENTED_POOL or
ename:VK_ERROR_OUT_OF_POOL_MEMORY instead of
out-of-host/out-of-device-memory, and improve the
<<fundamentals-errorcodes, description of those errors (internal issue
654).
* Add a NOTE documenting that flink:vkAcquireNextImageKHR can only signal
a single semaphore, and how to deal with that when multiple physical
devices in a logical device need to wait on it (internal issue 730).
* Improve description of pname:pNext chains of
slink:VkPhysicalDeviceImageFormatInfo2KHR and
slink:VkImageFormatProperties2KHR (internal issue 814).
* Clean up math markup issues in the <<textures, Image Operations>>
chapter (internal issue 818).
* Update validusage target to use more robust code for preprocessing, by
making direct use of Asciidoctor's preprocessor. Added uniqueItems check
to JSON vu schema and add clean_validusage target (internal issue 826).
* Update style guide to prohibit writing non-self-contained (on a single
bullet point) Valid Usage statements, and modify offending Valid Usage
statements in the Specification to match, to assist with automatic
extraction for the validation layers (internal issue 828).
* Add ename:VK_VALIDATION_CHECK_SHADERS_EXT to elink:VkValidationCheckEXT
of the `VK_EXT_validation_flags` extension, to selectively disable
shader validation.
* Remove duplicate valid usage statement for slink:VkImageMemoryBarrier.
* Modify reflow.py script to place VUID tag anchors standalone on a line
following their corresponding bullet point, and reflow the spec text
accordingly (this had been pending since the initial tag deployment).

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.

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.

Change log for May 20, 2017 Vulkan 1.0.50 spec update:
* Bump API patch number and header version number to 50 for this update.
Github Issues:
* Fix numerous minor issues with the VK_EXT_debug_report extension (public
issues 478, 483, 486, 489, 490).
Internal Issues:
* Update flink:vkAllocateDescriptorSets to specify conditions under which
to return ename:VK_ERROR_FRAGMENTED_POOL or
ename:VK_ERROR_OUT_OF_POOL_MEMORY instead of
out-of-host/out-of-device-memory, and improve the
<<fundamentals-errorcodes, description of those errors (internal issue
654).
* Add a NOTE documenting that flink:vkAcquireNextImageKHR can only signal
a single semaphore, and how to deal with that when multiple physical
devices in a logical device need to wait on it (internal issue 730).
* Improve description of pname:pNext chains of
slink:VkPhysicalDeviceImageFormatInfo2KHR and
slink:VkImageFormatProperties2KHR (internal issue 814).
* Clean up math markup issues in the <<textures, Image Operations>>
chapter (internal issue 818).
* Update validusage target to use more robust code for preprocessing, by
making direct use of Asciidoctor's preprocessor. Added uniqueItems check
to JSON vu schema and add clean_validusage target (internal issue 826).
* Update style guide to prohibit writing non-self-contained (on a single
bullet point) Valid Usage statements, and modify offending Valid Usage
statements in the Specification to match, to assist with automatic
extraction for the validation layers (internal issue 828).
* Add ename:VK_VALIDATION_CHECK_SHADERS_EXT to elink:VkValidationCheckEXT
of the `VK_EXT_validation_flags` extension, to selectively disable
shader validation.
* Remove duplicate valid usage statement for slink:VkImageMemoryBarrier.
* Modify reflow.py script to place VUID tag anchors standalone on a line
following their corresponding bullet point, and reflow the spec text
accordingly (this had been pending since the initial tag deployment).
New Extensions:
* `VK_AMD_texture_gather_bias_lod`

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
