* Update release number to 99.
Public Issues:
* Add missing pname:pMemoryHostPointerProperties description to
flink:vkGetMemoryHostPointerPropertiesEXT.txt (public pull request 896).
* Minor markup fixes (public pull request 900).
* Minor update to `khronos.css` and markup fixes (originally proposed in
public pull request 901, but done via an internal MR).
Internal Issues:
* Document restrictions on image queries for Y'CbCr formats in the
<<features-formats-requiring-sampler-ycbcr-conversion>> table as well as
for slink:sname:VkImageFormatProperties and slink:VkImageCreateInfo
(internal issue 1361).
* Correct type of the code:FragSizeEXT built-in in the
<<interfaces-builtin-variables, Built-In Variables>> section (internal
issue 1526).
* Clean up math in the <<textures, Image Operations>> chapter by
refactoring, using better naming conventions, updating diagrams to use
the correct orientation, etc. (internal merge request 2968).
* Fix minor typos for slink:VkImageCreateInfo and
slink:VkImageStencilUsageCreateInfoEXT.
* Add missing documentation for tlink:VkResolveModeFlagsKHR.
* Fix extension dependency of pname:scalarBlockLayout in the
<<features-features-requirements, Feature Requirements>> section.
* Fix indexing math for shader binding table calculations in the
<<shader-binding-table-indexing-rules, Indexing Rules>> section, and use
spelling "`any-hit`" consistently.
* Reconcile valid usage statement and text for sampled image layouts in
slink:VkWriteDescriptorSet
(https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/551).
* Make SPIR-V code:OpConvertUToPtr and code:OpConvertPtrToU operations
require a 64-bit integer for physical storage buffer pointers in the
<<spirvenv-module-validation, Validation Rules within a Module>>
section.
* Update to KaTeX 10.0.
New Extensions:
* `VK_EXT_filter_cubic`
* `VK_NV_dedicated_allocation_image_aliasing`

The `VK_KHR_vulkan_memory_model` extension allows use of the
|
|
<<memory-model,Vulkan Memory Model>>, which formally defines how to
|
|
synchronize memory accesses to the same memory locations performed by
|
|
multiple shader invocations.
|
|
|
|
=== New Enum Constants
|
|
|
|
* Extending elink:VkStructureType:
|
|
** ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VULKAN_MEMORY_MODEL_FEATURES_KHR
|
|
|
|
=== New Structures
|
|
|
|
* slink:VkPhysicalDeviceVulkanMemoryModelFeaturesKHR
|

.Note
|
|
====
|
|
Version 3 of the spec added a member
|
|
(pname:vulkanMemoryModelAvailabilityVisibilityChains) to
|
|
slink:VkPhysicalDeviceVulkanMemoryModelFeaturesKHR, which is an incompatible
|
|
change from version 2.
