It's mostly OpenCL 1.x, but it does use some aspects of the "memory model" that were introduced in OpenCL 2.0; related to memory synchronization between groups, used mostly in the kernel carryFused() I think.

It was plain 1.x not so long ago, but that stopped working on ROCm (because of the memory model), so switched to requiring 2.x at that point.
