* 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>>`

This extension advertises the SPIR-V *Int64Atomics* capability for Vulkan,
|
|
which allows a shader to contain 64-bit atomic operations on signed and
|
|
unsigned integers.
|
|
The supported operations include OpAtomicMin, OpAtomicMax, OpAtomicAnd,
|
|
OpAtomicOr, OpAtomicXor, OpAtomicAdd, OpAtomicExchange, and
|
|
OpAtomicCompareExchange.
