* 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:
* `VK_AMD_memory_overallocation_behavior`
* `VK_NV_ray_tracing`, replacing `VK_NVX_raytracing`
* Update release number to 88.
Public Issues:
* Make clear that
tname:PFN_vkDebugUtilsMessengerCallbackEXT::pname:messageTypes is a
bitmask, and correct a typo in the spelling of
slink:VkDebugUtilsMessengerCreateInfoEXT.txt::pname:messageType (public
pull request 800).
* Make an ABI-compatible change of the type of
slink:VkPhysicalDeviceDriverPropertiesKHR::pname:driverID to use the new
elink:VkDriverIdKHR type (public issue 811).
Internal Issues:
* Clarify for the <<features-features-shaderStorageImageExtendedFormats>>
feature and in the <<spirvenv-capabilities-table>> that the feature
means that all of the formats are supported, and that otherwise the
features can be queried per-format (internal issue 1273).
* Clarified interactions of `VK_EXT_external_memory_host` with host cache
management commands and structures flink:vkMapMemory,
flink:vkFlushMappedMemoryRanges, slink:VkMappedMemoryRange, and
flink:vkUnmapMemory using the new glossary term "`Host Mapped Device
Memory`" (internal issue 1385).
* Update the language for flink:vkCreateViSurfaceNN.txt describing the
pname:currentExtent of a VI surface to more accurately reflect current
capabilities, replacing "`undefined`" with more explicit behavior
(internal issue 1410).
New Extensions:
* `VK_EXT_calibrated_timestamps`
* `VK_EXT_image_drm_format_modifier` (this extension was previously
disabled in vk.xml, and has now been enabled after some changes to fix
performance issues).
* `VK_EXT_pci_bus_info`
* `VK_EXT_transform_feedback`
* `VK_GOOGLE_hlsl_functionality1`, exposing support for
`SPV_GOOGLE_hlsl_functionality1`.
* `VK_GOOGLE_decorate_string`, exposing support for
`SPV_GOOGLE_decorate_string`.
* Update release number to 87.
Public Issues:
* Merge flink:vkCmdPipelineBarrier self-dependency barrier VUs referring
to the same subpass dependency (public pull request 756).

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 86.
Internal Issues:
* Add new <<resources-image-creation-limits, Image Creation Limits>>
section and reference that from valid usage statements, reducing
combinatorial complexity of extension-dependent VUs. Also fixes some
underspecified limits (such as pname:maxMipLevels) in the VUs for
slink:VkImageCreateInfo when
slink:VkExternalMemoryImageCreateInfo::pname:externalMemoryHandles
contains multiple bits, and fixes incorrectly (and underspecified)
limits when an Android external format is used (internal issue 1370).
* Remove unused "`Fragment Area Granularity`" glossary entry accidentally
introduced in the 1.1.85 update.
New Extensions:
* `VK_KHR_driver_properties`
* `VK_KHR_shader_atomic_int64`
* The specification sources contain text for another extension,
`VK_EXT_image_drm_format_modifier`, but this extension is not yet
complete, and is marked disabled in `vk.xml`. The extension will be
enabled, and become part of the spec, only when the authors decide it is
ready.
* Update release number to 85.
Public Issues:
* Add self-dependency ename:VK_DEPENDENCY_BY_REGION_BIT valid usage
statements for slink:VkSubpassDependency(public pull request 778).
* Apply fix from pull request 742 to slink:VkSubpassDependency and
slink:VkSubpassDependency2 (public pull request 779).
* Specify the units of slink:VkBufferImageCopy::pname:bufferRowLength and
pname:bufferImageHeight as texels (public pull request 781).
* Better specify promoted parameter mapping in the
`<<VK_KHR_create_renderpass2>>` appendix (public pull request 782).
Internal Issues:
* Only include the <<fundamentals-validusage-versions, Valid Usage for
Newer Core Versions>> section in Vulkan 1.1 or later (internal issue
1381).
Other Issues:
* Clean up redundant valid usage language for the
`VK_ANDROID_external_memory_android_hardware_buffer` extension
interaction with slink:VkImageCreateInfo.
* Fix error in a flag name within valid usage statements for
slink:VkMemoryAllocateInfo.
* Clarify that memory types are not totally ordered in
slink:VkPhysicalDeviceMemoryProperties.
* For slink:VkWriteDescriptorSetInlineUniformBlockEXT, set
structextends="VkWriteDescriptorSet" in `vk.xml`, and make
slink:VkDescriptorSetLayoutBindingFlagsCreateInfoEXT::pname:pBindingFlags
optional.
* Add documentation of 'provisional' XML attribute to registry.txt.
New Extensions:
* `VK_NV_compute_shader_derivatives`
* `VK_NV_corner_sampled_image`

751).
* Fix misleading comment in `vk.xml` for
slink:VkDescriptorBufferInfo::pname:buffer (public pull request 762).
* Fix formatting of deprecation attributes in schema doc (public pull
request 767).
* Change `can` to `may` in the description of
elink:VkSparseImageFormatFlagBits, which are return values from queries
(public pull request 768).
* Prettify generated contact list in extension appendices, adding logos
and a New Issue link (public pull request 770).
* Enable sRGB conversion based on the image view format, not the image
format, in the <<textures-format-conversion, Format Conversion>> section
(public pull request 773).
* Fix typo in equation in the <<primsrast-lines-basic, Basic Line Segment
Rasterization>> section (public pull request 780).
* Fix special characters in GitHub contacts links (public pull request
783).
* Make clean_pdf target remove pdf folder (public pull request 784).
* Fix styleguide bad markup of block continuation (public pull request
792).
Other Issues:
* Allow a zero vertex attribute divisor in the
`<<VK_EXT_vertex_attribute_divisor>>` extension, exposed via the
slink:VkPhysicalDeviceVertexAttributeDivisorFeaturesEXT feature.
* Add missing `structextends="VkDeviceCreateInfo"` to
slink:VkPhysicalDeviceShaderDrawParameterFeatures and
slink:VkPhysicalDeviceBlendOperationAdvancedFeaturesEXT.
New Extensions:
* `VK_KHR_memory_model`
* `VK_EXT_astc_decode_mode`
* `VK_EXT_inline_uniform_block`
* Update release number to 82.
Public Issues:
* Add flink:vkDestroyPipelineLayout valid usage statement that the layout
must not have been used with command buffers still in the recording
state (public issue 730).
* Correct \<unused> tag for elink:VkResult in `vk.xml` (public merge
request 746).
Internal Issues:
* Add a valid usage statement to flink:vkQueueSubmit, and similar language
to the definitions of <<synchronization-queue-transfers-acquire, acquire
operations>> requiring that an acquire operation follow a previous
release of the same subresource (internal issue 1290).
* Add <<resources-image-format-features,Image Format Features>> and
<<resources-image-view-format-features,Image View Format Features>>
sections that precisely define the slink:VkFormatFeatures supported by
images and image views, and rewrite valid usage statements to reference
these sections instead of duplicating language (internal issue 1310).
* Reword and consolidate synchronization valid usage statements for
flink:vkCmdPipelineBarrier such that they correctly account for mutiple
possible self-dependencies (internal issue 1322).
* Change order of <<Standard sample locations>> for 2xMSAA (internal issue
1347).
* Add definitions of "`<<Correctly Rounded>>`" and "`<<ULP>>`" in the
SPIR-V environment appendix, and "`Units in the Last Place (ULP)`" in
the glossary.
New Extensions:
* `VK_NV_device_diagnostic_checkpoints`
* Update release number to 80.
Public Issues:
* Remove unused "`API Order`" term from glossary (public issue 657).
* Dynamically generate the extension appendix includes based on
information in `vk.xml`, including new metadata tags describing
deprecated, obsoleted, and promoted extensions (public pull request
690).
Internal Issues:
* Add valid usage statements to flink:vkCmdBindDescriptorSets to keep
offsets + range less than or equal to the buffer size (internal issue
1174).
New Extensions:
* `VK_EXT_conditional_render`
* `VK_KHR_create_renderpass2` (public issue 736)
* `VK_KHR_8bit_storage` (public issue 737)
* Update release number to 79.
Public Issues:
* Add a note to the <<features-required-format-support, Required Format
Support>> section clarifying that the required formats don't depend on
the used flags (public issue 671).
* Add a valid usage statement for flink:vkUpdateDescriptors that was
previously described for slink:VkImageSubresourceRange, but not as a
valid usage statement (public issue 713).
* Modify implicit valid usage generator script to not emit 'must: not be
0' for a parameter that is a pointer to a flags field, such as
pname:pPeerMemoryFeatures (public issue 729).
Internal Issues:
* Add definitions of "`obsoleted`" and "`deprecated`", and modify the
definition of "`promoted`" in the <<glossary, Glossary>> (internal issue
988).
* Add language for integer texel output conversions (the conversion is
undefined) to the <<textures-output-format-conversion]] Texel Output
Format Conversion>> section. Simplify and clarify the floating-point
conversion language in the <<fundamentals-general, General
Requirements>> section and the new <<fundamentals-fp-conversion,
Floating-Point Format Conversions>> section, and remove obsolete
language in the format-specific floating-point sections (internal issue
1275).
* Add the elink:VkVendorId enumerated type to the Vulkan API / XML /
header, so reserved Khronos vendor IDs can be referred to symbolically
by clients. Note that only Khronos vendor IDs (e.g. non-PCI vendor IDs)
are defined (internal issue 1299).
* Fix typo in the <<fig-non-strict-lines, Non strict lines>> table
(internal issue 1315).
* Clean up and simplify the
<<features-formats-requiring-sampler-ycbcr-conversion, YCbCr format
properties>> table and use symbols consistently with other tables. Add a
column for the number of planes.
* Add code:Float16 to the <<spirvenv-capabilities-table, List of optional
SPIR-V capabilities>> for the `VK_AMD_gpu_shader_half_float` extension.
* Update release number to 76.
Internal Issues:
* Add an exception clause to the license on `vk.xml`, enabling its use
with GPL-based projects (internal issue 1017).
* Remove the generated `vulkan_ext.[ch]` files, which are no longer
supported. Add `src/ext_loader/README.md` explaining why, and update
files in `xml/` to not generate them by default (internal issue 1268)
Other Issues:
* Fix typos in valid usage statements for the
ftext:vkDrawIndexedIndirectCount* commands, replacing
sizeof(VkDrawIndirectComment) with sizeof(VkDrawIndexedIndirectCommand).
* Modify the <<spirvenv-module-validation, Validation Rules within a
Module>> section to require code:NonReadable or code:NonWriteable in
SPIR-V code for images with an image format of code:Unknown if one of
the requisite code:shaderImageReadWithoutFormat or
code:shaderImageWriteWithoutFormat features is disabled.
New Extensions:
* `VK_KHR_get_display_properties2`
* `VK_KHR_draw_indirect_count`
* Update release number to 73.
Github Issues:
* Refine swapchain association with surface for slink:VkSwapchainKHR, with
matching valid usage statements for slink:VkSwapchainCreateInfoKHR and
discussion following the <<swapchain-wsi-image-create-info>> table
(public issue 637).
* Re-remove several valid usage statements from slink:VkImageCreateInfo
that had previously been removed at the time that
ename:VK_IMAGE_CREATE_EXTENDED_USAGE_BIT was introduced. These
statements had incorrectly been restored due to an glitch while merging
from the old `1.0` branch to the current `master` branch (public issue
683).
Internal Issues:
* Fix reference page generation and configure build to generate reference
pages 1.1 with all extensions, rather than core only, as was the case
for the 1.0 ref pages (internal issues 484, 1056, 1205).
* Require that
slink:VkMemoryDedicatedRequirements::pname:prefersDedicateAllocation is
ename:VK_TRUE when
slink:VkMemoryDedicatedRequirements::pname:requiresDedicateAllocation is
ename:VK_TRUE (internal issue 1222).
* Fix Ruby extension code so `diff_html` Makefile target works (internal
issue 1230).
* Update `genRelease` script to generate 1.1 + all extensions reference
pages - but not the single-page HTML / PDF versions, which are even
larger than the API spec (internal issue 1245).
Other Issues:
* Add missing attributes to `vk.xml` for `VK_ANDROID_native_buffer`.
* Specify that the slink:VkAttachmentDescription::pname:format member is
the format of the image *view* that will be used for the attachment.
* Use core sname:VkPhysicalDeviceFeatures2 in the `structextends` `vk.xml`
attribute for sname:VkPhysicalDeviceDescriptorIndexingFeaturesEXT and
sname:VkPhysicalDeviceDescriptorIndexingPropertiesEXT, rather than the
KHR equivalent it was promoted from.
* Fix the "`Fragment Input Attachment Interface`" glossary entry to match
the specification body.
* Clarify the interaction of sRGB images used as storage or texel buffers
with <<textures-output-format-conversion, Texel Output Format
Conversion>>.
* Moved three valid usage statements from
slink:VkRenderPassMultiviewCreateInfo up to
slink:VkRenderPassCreateInfo, and added a new valid usage statement for
slink:VkRenderPassInputAttachmentAspectCreateInfo.
* Added valid usage statements for slink:VkBufferMemoryBarrier and
slink:VkImageMemoryBarrier reflecting the global requirement that
"`non-sparse resources must be bound to memory before being recorded to
command`".
New Extensions:
- requires impls to honor resolution in #659
- addresses some confusion in Vulkan-LoaderAndValidationLayers/#2366
- require impls to support dependencies
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).
