Is Cuda 8.0 compatible with OpenCL 2.2?

I happened to notice that current OpenCL supported by khronos is already of version 2.2, please refer to .

And OpenCL coming with current Cuda 8.0 is still of version 1.1 ???

So, if I Cuda 8.0’s OpenCL1.1 to the khronos’ newest OpenCL2.2, will OpenCL still work properly?

Thank you very much
