* 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`

= Layers & Extensions (Informative)
|
|
|
|
Extensions to the Vulkan API can: be defined by authors, groups of authors,
|
|
and the Khronos Vulkan Working Group.
|
|
In order not to compromise the readability of the Vulkan Specification, the
|
|
core Specification does not incorporate most extensions.
|
|
The online Registry of extensions is available at URL
|
|
|
|
http://www.khronos.org/registry/vulkan/
|
|
|
|
and allows generating versions of the Specification incorporating different
|
|
extensions.
|
|
|
|
Most of the content previously in this appendix does not specify *use* of
|
|
specific Vulkan extensions and layers, but rather specifies the processes by
|
|
which extensions and layers are created.
|
|
As of version 1.0.21 of the Vulkan Specification, this content has been
|
|
migrated to the <<vulkan-styleguide, Vulkan Documentation and Extensions>>
|
|
document.
|
|
Authors creating extensions and layers must: follow the mandatory procedures
|
|
in that document.
|
|
|
|
The remainder of this appendix documents a set of extensions chosen when
|
|
this document was built.
|
|
Versions of the Specification published in the Registry include:
|
|
|
|
* Core API + mandatory extensions required of all Vulkan implementations.
|
|
* Core API + all registered and published Khronos (`KHR`) extensions.
|
|
* Core API + all registered and published extensions.
|
|
|
|
Extensions are grouped as Khronos `KHR`, multivendor `EXT`, and then
|
|
alphabetically by author ID.
|
|
Within each group, extensions are listed in alphabetical order by their
|
|
name.
|
|
|
|
[NOTE]
|
|
.Note
|
|
====
|
|
As of the initial Vulkan 1.1 public release, the `KHX` author ID is no
|
|
longer used.
|
|
All `KHX` extensions have been promoted to `KHR` status.
|
|
Previously, this author ID was used to indicate that an extension was
|
|
experimental, and is being considered for standardization in future `KHR` or
|
|
core Vulkan API versions.
|
|
We no longer use this mechanism for exposing experimental functionality.
|
|
|
|
Some vendors may use an alternate author ID ending in `X` for some of their
|
|
extensions.
|
|
The exact meaning of such an author ID is defined by each vendor, and may
|
|
not be equivalent to `KHX`, but it is likely to indicate a lesser degree of
|
|
interface stability than a non-`X` extension from the same vendor.
