Release 1.12 -- beta 1 Sep 2022 (compared to 1.11)
--------------------------------------------------
Big Deal Changes:
* Batch shading: A fully operational "batch shading" support when using CPUs
supporting the AVX2 or AVX512 instruction set architectures, allows shading
8 or 16 points at a time, accelerated by using SIMD instructions.
* A reasonable subset of the OSL language can run on NVIDIA GPUs for
Cuda or OptiX-based renderers.
* Synchronize with MaterialX on a minimum standard set of material closures.
This is reflected in both the OSL spec as well as reference implementations
of those closures in testrender. #1533 #1536 #1537 #1538 #1539 #1541 #1542
#1547 #1557
* **Batch shading**: A fully operational "batch shading" support when using
CPUs supporting the Intel AVX2 or AVX512 instruction set architectures,
allows shading 8 or 16 points at a time, accelerated by using SIMD
instructions. (Changes contributed by Intel.)
* **OptiX**: A reasonable subset of the OSL language can run on NVIDIA GPUs
for Cuda or OptiX-based renderers.
* **Standardized material closures**: Synchronize with MaterialX on a minimum
standard set of material closures. This is reflected in both the OSL spec as
well as reference implementations of those closures in testrender. #1533
#1536 #1537 #1538 #1539 #1541 #1542 #1547 #1557

Dependency and standards requirements changes:
* The minimum (and default) compilation mode is now C++14. C++17 and 20 are
