* 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

|
The `VK_KHR_16bit_storage` extension allows use of 16-bit types in shader
|
|
input and output interfaces, and push constant blocks.
|
|
This extension introduces several new optional features which map to SPIR-V
|
|
capabilities and allow access to 16-bit data in code:Block-decorated objects
|
|
in the code:Uniform and the code:StorageBuffer storage classes, and objects
|
|
in the code:PushConstant storage class.
|
|
This extension allows 16-bit variables to be declared and used as
|
|
user-defined shader inputs and outputs but does not change location
|
|
assignment and component assignment rules.
|
|
|
|
=== New Enum Constants
|
|
|
|
* Extending elink:VkStructureType:
|
|
** ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_16BIT_STORAGE_FEATURES_KHR
|
|
|
|
=== New Structures
|
|
|
|
* slink:VkPhysicalDevice16BitStorageFeaturesKHR
|
|
|
|
=== New SPIR-V Capabilities
|
|
|
|
* <<spirvenv-capabilities-table-16bitstorage,code:StorageBuffer16BitAccess>>
|
|
* <<spirvenv-capabilities-table-16bitstorage,code:UniformAndStorageBuffer16BitAccess>>
|
|
* <<spirvenv-capabilities-table-16bitstorage,code:StoragePushConstant16>>
|
|
* <<spirvenv-capabilities-table-16bitstorage,code:StorageInputOutput16>>
|
|
|
|
=== Promotion to Vulkan 1.1
|
|
|
|
All functionality in this extension is included in core Vulkan 1.1, with the
|
|
KHR suffix omitted.
|
|
The original type, enum and command names are still available as aliases of
|
|
the core functionality.
