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

* Update release number to 81.
Public Issues:
* Fix missing "`valid`" phrasing in some obscure cases (public pull
request 605).
* Replace improper use of cannot: referring to the implementation in the
description of the
<<features-limits-maxUpdateAfterBindDescriptorsInAllPools,
pname:maxUpdateAfterBindDescriptorsInAllPools>> limit (public pull
request 738).
* Reorder description of bits in elink:VkPipelineStageFlagBits and the
<<synchronization-pipeline-stages-supported, Supported pipeline stage
flags>> table to match their definition order (public pull request 740).

description>> and <<shaders-geometry-execution, Geometry Shader
Execution>> descriptions consistent with other pipeline stages (internal
issue 1325).
* Mark the `VK_NV_glsl_shader` extension as deprecated.
* Adjust the per-instance vertex attribute offset formula specified by
`VK_EXT_vertex_attribute_divisor` for
slink:VkVertexInputBindingDivisorDescriptionEXT so that the interaction
between pname:firstInstance and pname:divisor matches the OpenGL
convention (internal issue 1333).
- update script to detect better structs that do not need "valid"
- update vk.xml and schema to say `noautovalidity` as a hint to the
script
- fix missing const in VkValidationFlagsEXT
- update some cases that were probably avoiding the bug
* Update release number to 80.

* `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.
Provides a 12.6% size savings for vkspec.html
(697770 B -> 609679 B, gzipped), because:
(1) plaintext is smaller than base64-encoded plaintext, and
(2) base64 does not gzip as well as plaintext SVG.

instead of just their names (public issue 697).
* Resume publishing updated Vulkan 1.0 + KHR extensions and Vulkan 1.0 +
all extensions versions of the specification (public issue 722).
* Reapply fixes from public pull request 698 for
`VK_ANDROID_external_memory_android_hardware_buffer`, which accidentally
were reverted at some point (public pull request 724).

in the presence of the
`VK_ANDROID_external_memory_android_hardware_buffer` extension (public
pull request 725).

Internal Issues:
* When building specifications containing vendor extensions, add terms to
the Khronos spec copyright specifying that the result is not a ratified
specification (internal issue 739).
* Change the value of the
pname:maxDescriptorSetUpdateAfterBindUniformBuffers minimum limit to 72
(6 times pname:maxPerStageDescriptorUpdateAfterBindUniformBuffers) in
the <<features-limits-required, Required Limits>> table (internal issue
1300).

reflect the minimum alignment requirements for the buffer's usages, and
make dynamic offset alignment valid usage more explicit for
flink:vkBindBufferMemory and flink:vkCmdBindDescriptorSets (internal
issue 1170).
* Explicitly state that objects of type code:OpTypeImage,
code:OpTypeSampler, and code:OpTypeSampledImage must not be stored to in
the <<spirvenv-module-validation, Validation Rules within a Module>>
section (internal issue 1262).
* Clarify rules about validating descriptor set/binding against storage
class and descriptor type in the <<spirvenv-module-validation,
Validation Rules within a Module>> section, and add an anchor for and
references to the <<interfaces-resources-storage-class-correspondence,
Shader Resource and Storage Class Correspondence>> table (internal issue
1266).
* Use correct spelling of SPIR-V decoration code:NonWritable in several
places (internal issue 1298).
Other Issues:
* Update specification links to files in the old
KhronosGroup/Vulkan-LoaderAndValidationLayers repository with

* Move validity requirement for slink:VkSamplerCreateInfo into the valid
usage block instead of the body text, and give it a VUID.
* Use the full name of the "`style guide`" in a reference in the

Internal Issues:
* Add an exception clause to the license on `vk.xml`, enabling its use
with GPL-based projects (internal issue 1017).

supported. Add `src/ext_loader/README.md` explaining why, and update
files in `xml/` to not generate them by default (internal issue 1268)

* Fix typos in valid usage statements for the
ftext:vkDrawIndexedIndirectCount* commands, replacing
sizeof(VkDrawIndirectComment) with sizeof(VkDrawIndexedIndirectCommand).

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`
