* 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`
* `VK_NV_fragment_shader_barycentric`
* `VK_NV_mesh_shader`
* `VK_NV_representative_fragment_test`
* `VK_NV_scissor_exclusive`
* `VK_NV_shader_image_footprint`
* `VK_NV_shading_rate_image`
* `VK_NVX_raytracing`
* Update release number to 84.
Public Issues:
* Fix code sample in the `<<VK_EXT_debug_utils>>` extension (public issue
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 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.
