Github Issues:

  * VUs for graphics pipelines have been reworked regarding state subsets,
    along with the sections describing those state subsets. VUs that
    previously ambiguously stated "`If the pipeline is _created with_ <state
    subset>...`" now instead state "`If the pipeline _requires_ <state
    subset>...`" Those VUs link to the state subset descriptions, which
    previously did not actually indicate anything about when they were
    required, which was instead left to the section on complete subsets. The
    subset sections now document their own independent requirements for when
    they are needed, so that the VUs explicitly point to relevant text.
    Additional VUs have also been added to mirror these updated sections,
    uncovering a handful of incorrect edge cases and clarifying them.
    Previous VUs that required a complete pipeline were now redundant, so
    have been removed. (public issue 1793).
  * Add missing code:SPV_EXT_opacity_micromap to XML (public pull request
    2131).
  * Fix typo in code:SPV_INTEL_shader_integer_functions2 XML (public pull
    request 2132).

Internal Issues

  * Use "`commands are called *in* a command buffer`" rather than "`*on* a
    command buffer`", and add this case to the style guide (internal issue
    3480).
  * Fix common draw dispatch VU 07753 for the
    slink:VkImageView::pname:format to match the code:OpTypeImage
    code:Sampled code:Type (internal issue 3481).
  * Create common draw and slink:VkGraphicsPipelineCreateInfo VUs for
    pname:alphaToCoverageEnable (internal merge request 5811).
  * Add elink:VkDynamicState entry for
    ename:VK_DYNAMIC_STATE_ATTACHMENT_FEEDBACK_LOOP_ENABLE_EXT (internal
    merge request 5894).
  * Use consistent wording for VUs referring to external memory handles
    (internal merge request 5895).
  * Remove redundant <<spirvenv-module-validation-standalone, Standalone
    SPIR-V Validation>> VU 04662 (internal merge request 5898).
  * Revert common draw VU 07620, which was accidentally removed by
    apiext:VK_EXT_shader_object (internal merge request 5899).
  * Allow slink:VkVideoDecodeInfoKhr::pname:pReferenceSlots to be `NULL` in
    its description (internal merge request 5900).
  * Fix slink:VkGraphicsPipelineCreateInfo pipeline topology VUs when
    pname:dynamicPrimitiveTopologyUnrestricted is set and the dynamic state
    is enabled (internal merge request 5916).
