* Happy 50th Lunar Landing Day!
* Update release number to 116.
Internal Issues:
* Clarify that flink:vkCmdBeginQuery is the same as
flink:vkCmdBeginQueryIndexEXT with index = 0, and that
flink:vkCmdEndQuery is the same as flink:vkCmdEndQueryIndexEXT with
index = 0 (internal issue 1735).
* Clarify that when copying the depth aspect between buffers and images
via slink:VkBufferImage Copy, the depth values in buffer memory must be
in range if the `<<VK_EXT_depth_range_unrestricted>>` extension is not
enabled (internal issue 1737).
* Minor language tweaks in the <<spirvenv-module-validation, Validation
Rules within a Module>> section (internal issue 1744).
* Change the slink:VkPhysicalDeviceFloatControlsPropertiesKHR structure in
the `<<VK_KHR_shader_controls>>` extension. This is a rare case of
breaking the interface of an existing extension to acknowledge the
reality of divergent vendor implementations that could not be described
properly otherwise, and the breaking change is considered acceptable
given the expected low use of the extension (internal issue 1734).
Specific changes:
** Added the slink:VkShaderFloatControlsIndependenceKHR enumeration to
describe the three possible behaviors.
** Renamed pname:separateDenormSettings to
pname:denormBehaviorIndependence.
** Renamed pname:separateRoundingModeSettings to
pname:roundingModeIndependence
* Add a missing valid usage statement for
slink:VkQueryPoolCreateInfo::pname:queryCount (internal issue 1742).
* Update the `<<VK_NV_shading_rate_image>>` appendix to list all
interfaces defined by the extension.
* Add a valid usage statement to
slink:VkWriteDescriptorSetAccelerationStructureNV to clarify that
acceleration structure descriptors must be top level structures.
New Extensions:
* `<<VK_EXT_subgroup_size_control>>`
