* Update release number to 107.
Public Issues:
* Fix revision date for the `<<VK_AMD_gpu_shader_half_float>>` appendix
(public issue 617).
* Make <<synchronization-pipeline-barriers-subpass-self-dependencies,
subpass self-dependencies>> less restrictive (public issue 777).
* Fix the `<<VK_EXT_full_screen_exclusive>>` dependency on
`<<VK_KHR_win32_surface>>` in `vk.xml` (public pull request 849).
* Remove single-page (`apispec.html`) refpage sub-targets from the
Makefile `allman` target and the build instructions. The target is still
present in the Makefile, but we have not been actively maintaining the
single-page document and do not promise it will work. The full
Specification and the individual API reference pages are what we support
and publish at present (public issue 949).
Internal Issues:
* De-duplicate common valid usage statements shared by multiple commands
or structures by using asciidoctor includes and dynamically assigning
part of the valid usage ID based on which command or structure they're
being applied to (internal issue 779).
* Add reference pages for constructs not part of the formal API, such as
platform calling convention macros, and script changes supporting them
This required suppressing some check_spec_links warning classes in order
to pass CI, until a more sophisticated fix can be done (internal issue
888).
* Change math notation for the elink:VkPrimitiveTopology descriptions to
use short forms `v` and `p` instead of `vertex` and `primitive`,
increasing legibility (internal issue 1611).
* Rewrite generated file includes relative to a globally specified path,
fixing some issues with refpage generation (internal issue 1630).
* Update contributor list for `<<VK_EXT_calibrated_timestamps>>`.
* Fix use of pathlin in `scripts/generator.py` so the script will work on
Windows under Python 3.5 (internal merge request 3107).
* Add missing conditionals around the
<<descriptorsets-accelerationstructure, Acceleration Structure>>
section (internal merge request 3108).
* More script synchronization with OpenXR spec repository (internal merge
request 3109).
* Mark the `<<VK_AMD_gpu_shader_half_float>>` and
`<<VK_AMD_gpu_shader_int16>>` extensions as deprecated in `vk.xml` and
the corresponding extension appendices (internal merge request 3112).
New Extensions:
* `<<VK_EXT_headless_surface>>`
* Update release number to 97.
Public Issues:
* Add a special case to the <<renderpass-compatibility, Render Pass
Compatibility>> rules allowing single-subpass renderpasses to be
compatible even if they have different resolve attachment references
(public issue 835).
* Fix the miss shader binding table record address rule in the
<<shader-binding-table-indexing-rules, Miss Shaders>> section to index
by code:missIndex, not code:sbtOffset (public issue 875).
Internal Issues:
* Add a missing anchor to the elink:VkSamplerCreateFlagBits language
(internal issue 1483).
* Add missing implicit valid usage include for slink:VkHdrMetadataEXT and
corresponding `noautovalidity` attributes in `vk.xml` for the
externally-defined metadata properties (internal issue 1514).
* Remove restrictions on the `mask` parameter of SPIR-V's
code:OpGroupNonUniformXor in the <<spirvenv-module-validation,
Validation Rules within a Module>> appendix (internal merge request
2971).
* Restore `noautovalidity` attribute for
slink:VkPipelineViewportWScalingStateCreateInfoNV::pname:pViewportWScalings
in `vk.xml` (internal merge request 2975).
* Update copyright dates on Khronos-copyrighted files to 2019 (internal
merge request 2980).
New Extensions:
* `VK_KHR_depth_stencil_resolve`
* `VK_EXT_buffer_device_address`
* `VK_EXT_memory_budget`
* `VK_EXT_memory_priority`
* `VK_EXT_validation_features`
* Update release number to 92.
Public Issues:
* Move and modify valid usage statements dealing with pname:aspectMask in
flink:vkCmdClearColorImage, flink:vkCmdClearDepthStencilImage, and
slink:VkClearAttachment, so they are in places where all necessary
information is available (public issue 529).
* Fix math markup in <<textures-texel-anisotropic-filtering, Texel
Anisotropic Filtering>> (public pull request 840).
* Fix misspellings (public pull request 845).
Internal Issues:
* Add installation instructions and a Makefile "`chunked`" target for
chunked HTML generation (internal issue 1352).
* Fix pipeline mesh diagram style; also fix a minor bug in the classic
pipeline diagram where vertex/index buffers wrongly fed into the vertex
shader (internal issue 1436).
* Make asciidoctor ERROR output raise an error, and don't suppress
executed command output from CI make invocation (internal issue 1454).
* Minor typo fixes and clarifications for `VK_NV_raytracing`.
* Cleanup extension-specific properties
** Remove duplicated documentation for pname:maxDiscardRectangles,
pname:pointClippingBehavior, and pname:maxVertexAttribDivisor (they
shouldn't be documented with the other members of
slink:VkPhysicalDeviceLimits at all).
** Remove duplicate anchor for pname:maxVertexAttribDivisor
** Consistently document stext:VkPhysicalDevice<Extension>PropertiesKHR
*** Always document pname:sType/pname:pNext (was inconsistent before)
*** Always mention chaining to slink:VkPhysicalDeviceProperties2 (and not
as slink:VkPhysicalDeviceProperties2KHR)
*** Always include Valid Usage statements last
* Update Makefile 'checklinks' target and associated scripts, and fix
markup problems identified by checkLinks.py, so that we can rely on the
checklinks script as part of Gitlab CI.
* Update release number to 91.
Public Issues:
* Update Ubuntu subsystem build instructions in `BUILD.adoc` (public pull
request 624).
* Delete the `VK_KHR_mir_surface` extension from the Specification and
XML, due to EOL of the only driver known to have supported it, and
near-EOL of Mir itself (public issue 814).
* Fix options for some figures that were using old ones (public pull
request 841).
* Fix various accidentally repeated words (public pull request 843).
* Use `time.process_time()`, introduced in Python 3.3, in the scripts
instead of `time.clock()`, which will be removed in Python 3.8 (public
pull request 844).
Internal Issues:
* Update valid usage statements for
`VK_ANDROID_external_memory_android_hardware_buffer` in
slink:VkMemoryAllocateInfo,
slink:VkImportAndroidHardwareBufferInfoANDROID, and
flink:vkGetAndroidHardwareBufferPropertiesANDROID to actually be
verifiable (internal issue 1419).
* Update valid usage statements for
`VK_ANDROID_external_memory_android_hardware_buffer` in
slink:VkMemoryAllocateInfo, slink:VkImageCreateInfo, and
slink:VkImageViewCreateInfo to move valid usage statements in
doubly-nested bullet points up one level, accomodating limitations of
the valid usage extraction script that creates `validusage.json`
(internal issue 1434).
* Fix typo etext:VK_ACCESS_SHADING_RATE_IMAGE_BIT_NV to the correct
ename:VK_ACCESS_SHADING_RATE_IMAGE_READ_BIT_NV.
* Add missing etext:VK_STRUCTURE_TYPE_* tokens to appendices for
extensions missing them.
New Extensions:

to the same subpass dependency (public pull request 756).
* Describe default value of `"optional"` attribute in the registry schema
document (public issue 769)
* Fix links in <<VK_NVX_raytracing>> extension (public pull request 805).
* Mark the <<VK_KHR_mir_surface>> extension obsolete (see public issue 814
- does not close this, however).
* Fix missing endif in Image Creation block (public issue 817).
Internal Issues:
* Clarify that the compressed texture formats corresponding to
<<features-features-textureCompressionETC2>>,
<<features-features-textureCompressionASTC_LDR>>, and
<<features-features-textureCompressionBC>> is not contingent on the
feature bits, and may be supported even if the features are not enabled
(internal issue 663).
* Clarify that code:FragStencilRefEXT is output only in the
<<interfaces-builtin-variables, Built-In Variables>> section (internal
issue 1173).
* Identify and correct many overly-aggressive uses of "`undefined`", and
narrow them down, where straightforward to do so. Mark such resolved
uses of "`undefined`" with the custom undefined: macro. Add a new
<<writing-undefined, Describing Undefined Behavior>> section (internal
issue 1267).
* Don't require code:inline_uniform_block descriptors to be populated
before use in the flink:vkAllocateDescriptorSets section (internal issue
1380).
* Allow suppressing inline SVG images by controlling this with an
attribute set in the Makefile, rather than the explicit [%inline]
directive (internal issue 1391).
* Mark 'Khronos' as a registered trademark in several places, now that it
is one.
* Fix typo in the <<VK_KHR_shader_atomic_int64>> appendix using the GLSL
naming of the compare exchange op when referring to the SPIR-V op.
* Specify in the flink:vkGetPhysicalDeviceQueueFamilyProperties section
that all implementations must support at least one queue family, and
that every queue family must contain at least one queue.
* Make slink:VkPipelineDynamicStateCreateInfo::pname:dynamicStateCount,
slink:VkSampleLocationsInfoEXT::pname:sampleLocationsPerPixel, and
slink:VkSampleLocationsInfoEXT::pname:sampleLocationsCount optional, to
fix bogus implicit valid usage checks that were causing failures in the
conformance tests.
* Fix vendor tag in reserved extension 237 constants. Does not affect
anything since it's just a placeholder, but this should avoid further
comments.
* Minor markup fixes in some extension appendices.
New Extensions:
* `<<VK_FUCHSIA_imagepipe_surface>>`
* Update release number to 83.
Public Issues:
* Use [%inline] directive for all SVGs to reduce file size (public pull
request 734).
* Convert XML `value` aliases into \<alias> tags (public pull request
747).
* Fix metadoc script showing non-selected extensions (public pull request
748).
* Reapply public pull request 742 to make
ename:VK_PIPELINE_STAGE_CONDITIONAL_RENDERING_BIT_EXT part of the
graphices pipeline (public pull request 749).
* Fix numerous typos related to accidental duplication of words (public
pull request 760).
* Fix `vk.xml` contact typos (public pull request 761).
Internal Issues:
* Add images to the <<Standard sample locations>> table (internal issue
1115).
* Add a definition of "`Inherited from`" precision in the
<<spirvenv-precision-operation, Precision and Operation of SPIR-V
Instructions>> section (internal issue 1314).
* Clarify that both built-in and user-defined variables count against the
location limits for shader interfaces in the
<<interfaces-iointerfaces-locations, Location Assignment>> section
(internal issue 1316).
* Merge "`required`" capabilities into the <<spirvenv-capabilities-table,
list of optional: SPIR-V capabilities>> (internal issue 1320).
* Relax the layout matching rules of descriptors referring to only a
single aspect of a depth/stencil image, by reference to the new
<<resources-image-layouts-matching-rule, Image Layout Matching Rules>>
section (internal issue 1346).
* Revert extension metadoc generator warning about name mismatches to a
diagnostic, due to annoying warnings in build output for conscious
choices we've made (internal issue 1351).
Other Issues:
* Reserve bits for pending vendor extensions.
* Make Vulkan consistent with SPIR-V regarding code:DepthReplacing and
code:FragDepth in the <<interfaces-builtin-variables, Built-In
Variables>> section.
* Add missing ChangeLog entries for the previous three spec updates.
* Update release number to 72.
Github Issues:
* Restructure the repository to put the specification `Makefile` and
associated spec source material at the top level, `vk.xml` and
associated scripts material in `xml/`, and generated include and source
files in `include/vulkan/` and `src/ext_loader/`, respectively (public
issue 436).
* Add missing bullet point markup to flink:vkCmdCopyImage valid usage
statement, so it gets a VUID assigned (public issue 627).
* Fix broken links in a couple of extension appendices (public pull
request 665).
* Add the \<platform> tag to the index in section 4.1 of the registry
schema documentation, and add the protect= attribute of \<extension>
tags to the comments in `registry.rnc` (public issues 673, 678).
* Add missing valid usage statements for sparse image interactions to
flink:VkImageCreateInfo (public pull request 675).
* Fix improper usage and grammar of "`can: not`" (public pull request
681).
* Remove duplicate spec language and NOTE on present layout between the
flink:vkAcquireNextImageKHR and flink:vkAcquireNextImage2KHR commands
(public pull request 685).
* Fix some typos and markup issues (public pull request 689; public issues
642, 667, 687).
* Fix typo etext:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_FENCE_FD_BIT ->
ename:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_SYNC_FD_BIT in the
<<external-semaphore-handle-types-compatibility, External semaphore
handle types compatibility>> table (public pull request 691).
Internal Issues:
* Remove the need for the "`noautovalidity`" attribute on extension
structures in `vk.xml`. It is now implied by the "`structextends`"
attribute instead (internal issue 942).
* Replace uses of "`currently bound`" with "`bound`", since "`currently`"
is redundant and distracting, and add a corresponding rule to the style
guide (internal issue 993).
* Fixed subtle issues with the last updates to flink:vkAcquireNextImageKHR
language that had resulted in ambiguities (internal issue 1178).
* Make it clear that only one query of a given type is allowed at a time
by reordering valid usage statements for flink:vkCmdBeginQuery and
flink:vkCmdEndQuery, and removing redundant ones (internal issue 1213).
* Swapped OL1 and OL3 in `tessparamUL.svg` to match previous version, and
fixed where "`(no edge)`" appears (internal issue 1215).
Other Issues:
* Fixed a minor problem with the valid usage statement extraction script,
and corresponding markup in the spec source.
New Extensions:
* `VK_AMD_shader_core_properties`
* `VK_EXT_descriptor_indexing`
* `VK_NV_shader_subgroup_partitioned`
associated material at the top level, vk.xml and associated material in
xml/, and generated include and source files in include/vulkan/ and
src/ext_loader/, respectively (public issue 436).
