* 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`

|
`VK_KHR_maintenance1` adds a collection of minor features that were
|
|
intentionally left out or overlooked from the original Vulkan 1.0 release.
|
|
|
|
The new features are as follows:
|
|
|
|
* Allow 2D and 2D array image views to be created from 3D images, which
|
|
can then be used as color framebuffer attachments.
|
|
This allows applications to render to slices of a 3D image.
|
|
* Support flink:vkCmdCopyImage between 2D array layers and 3D slices.
|
|
This extension allows copying from layers of a 2D array image to slices
|
|
of a 3D image and vice versa.
|
|
* Allow negative height to be specified in the
|
|
slink:VkViewport::pname:height field to perform y-inversion of the
|
|
clip-space to framebuffer-space transform.
|
|
This allows apps to avoid having to use `gl_Position.y = -gl_Position.y`
|
|
in shaders also targeting other APIs.
|
|
* Allow implementations to express support for doing just transfers and
|
|
clears of image formats that they otherwise support no other format
|
|
features for.
|
|
This is done by adding new format feature flags
|
|
ename:VK_FORMAT_FEATURE_TRANSFER_SRC_BIT_KHR and
|
|
ename:VK_FORMAT_FEATURE_TRANSFER_DST_BIT_KHR.
|
|
* Support flink:vkCmdFillBuffer on transfer-only queues.
|
|
Previously flink:vkCmdFillBuffer was defined to only work on command
|
|
buffers allocated from command pools which support graphics or compute
|
|
queues.
|
|
It is now allowed on queues that just support transfer operations.
|
|
* Fix the inconsistency of how error conditions are returned between the
|
|
flink:vkCreateGraphicsPipelines and flink:vkCreateComputePipelines
|
|
functions and the flink:vkAllocateDescriptorSets and
|
|
flink:vkAllocateCommandBuffers functions.
|
|
* Add new ename:VK_ERROR_OUT_OF_POOL_MEMORY_KHR error so implementations
|
|
can give a more precise reason for flink:vkAllocateDescriptorSets
|
|
failures.
|
|
* Add a new command flink:vkTrimCommandPoolKHR which gives the
|
|
implementation an opportunity to release any unused command pool memory
|
|
back to the system.
|

|
|
|
=== Promotion to Vulkan 1.1
|
|
|
|
All functionality in this extension is included in core Vulkan 1.1, with the
|
|
KHR suffix omitted.
|
|
The original type, enum and command names are still available as aliases of
|
|
the core functionality.
|
|
|
|
=== Issues
|
|
|
|
. Are viewports with zero height allowed?
|
|
+
|
|
*RESOLVED*: Yes, although they have low utility.
