* Update release number to 124.
Github Issues:
* Fix Makefile SPECREMARK macro to work when not building in a git tree
(public issue 992).
* Ignore pname:aspectMask for unused attachments in
slink:VkSubpassDescription2KHR valid usage statements (public pull
request 1028).
* Minor markup / spelling fixes (public pull requests 1035, 1045).
Internal Issues:
* Fix markup in Valid Usage statement for slink:VkCreateFramebuffer
(internal issue 1823).
* Add a new <<synchronization-signal-operation-order, _signal operation
order_>> section to the synchronization chapter which describes in
detail the ordering guarantees provided by the API between fence and
semaphore signal operations (internal merge request 3368).
* Move generated `appendix/meta/` files into the Makefile GENERATED
directory (internal merge request 3381).
New Extensions
* `<<VK_KHR_shader_clock>>`
* `<<VK_KHR_timeline_semaphore>>`

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

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