* 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).

=== Description
|
|
|
|
The `VK_KHR_shader_float16_int8` extension allows use of 16-bit
|
|
floating-point types and 8-bit integer types in shaders for arithmetic
|
|
operations.
|
|
|
|
It introduces two new optional features pname:shaderFloat16 and
|
|
pname:shaderInt8 which directly map to the code:Float16 and the code:Int8
|
|
SPIR-V capabilities.
|
|
The `VK_KHR_shader_float16_int8` extension also specifies precision
|
|
requirements for half-precision floating-point SPIR-V operations.
|
|
This extension does not enable use of 8-bit integer types or 16-bit
|
|
floating-point types in any <<interfaces-iointerfaces, shader input and
|
|
output interfaces>> and therefore does not supersede the
|
|
`<<VK_KHR_8bit_storage>>` or `<<VK_KHR_16bit_storage>>` extensions.
