* Update release number to 120.
Github Issues:
* Add slink:VkAccelerationStructureTypeNV explicitly to extension XML for
`<<VK_NV_ray_tracing>>` (public issue 848).
* Add missing valid usage statements for feature flags in
slink:VkCommandBufferInheritanceInfo (public pull request 1017).
Internal Issues:
* Clarify behavior of non-premultiplied destination colors for
`<<VK_EXT_blend_operation_advanced>>` prior to the definition of
slink:VkBlendOverlapEXT (internal issue 1766).
* Fix the confusing phrasing "`no other queue must: be (doing something)`"
for flink:vkQueuePresentKHR, flink:vkQueueSubmit, and
flink:vkQueueBindSparse (internal issue 1774).
* Add `<<VK_EXT_validation_features>>` flag to enable best practices
checks, which will soon be available in the validation layer (internal
issue 1779).
* Specify allowed characters for VUID tag name components in the style
guide (internal issue 1788).
* Update links to SPIR-V extension specifications, and parameterize their
markup in case the URLs change in the future (internal issue 1797).
* Fix an off-by-one error in the valid usage statement for
slink:VkPipelineExecutableInfoKHR (internal merge request 3303).
* Clean up markup indentation not matching the style guide (internal merge
request 3314).
* Minor script updates to allow refpage aliases, generate a dynamic TOC
for refpages, generate Apache rewrite rules for aliases, open external
links from refpages in a new window, and synchronize with the OpenCL
scripts. This will shortly enable a paned navigation setup for refpages,
similar to the OpenCL 2.2 refpages (internal merge request 3322).
* Script updates to add tests to the checker, refactor and reformat code,
generate better text for some valid usage statements, use more Pythonic
idioms, and synchronize with the OpenXR scripts (internal merge request
3239).
* Script updates and minor fixes in spec language to not raise checker
errors for refpage markup of pages not existing in the API, such as
VKAPI_NO_STDINT_H. Remove corresponding suppression of some
check_spec_links.py tests from .gitlab-ci.yml and 'allchecks' target
(internal merge request 3315).
* Update release number to 113.
Github Issues:
* Fix typo in `<<VK_EXT_global_priority>>` appendix (public issue 979).
Internal Issues:
* Expand the explanation of
slink:VkSamplerYcbcrConversionImageFormatPropertiesKHR::pname:combinedImageSamplerDescriptorCount,
and explain how it interacts with slink:VkWriteDescriptorSet,
slink:VkDescriptorSetLayoutBinding::pname:descriptorCount, and
slink:VkDescriptorPoolSize::pname:descriptorCount (internal issue 1643).
* Clarify restrictions on components for code:OpImageGather in the
<<spirvenv-module-validation, Validation Rules within a Module>> section
(internal issue 1707).
* Clarify the descriptions of <<limits-computeUnitsPerShaderArray,
pname:computeUnitsPerShaderArray>> and <<limits-wavefrontSize,
pname:wavefrontSize>> fields in
slink:VkPhysicalDeviceShaderCorePropertiesAMD.
New Extensions:
* `<<VK_EXT_texel_buffer_alignment>>`
* `<<VK_EXT_shader_demote_to_helper_invocation>>`
