OpenCL 3.1 is here.
The Khronos Group has moved several capabilities into the core spec, including SPIR-V kernels, subgroups, and integer dot products.
Also includes improvements to the memory model and synchronization, plus better alignment with Vulkan via device UUID queries.
Implementations are already underway across major vendors and open source projects.

The OpenCL Working Group has published the first in a series of cooperative matrix extensions — and your feedback can help shape them before finalization.
cl_khr_cooperative_matrix brings cooperative matrix load, store, and multiply-add to OpenCL, developed with Arm, Intel, and Qualcomm. A companion OpenCL C language extension is also in RFC.
