Maybe it was just my feeling, as I haven't seen pretty much anyone working with it in last year or so

There are official Khronos teleconferences of the OpenCL group just about every week and an upcoming face-to-face meeting next month, and various other meetings going on all the time.

OpenCL is certainly being updated. OpenCL 2.1 was a surprisingly major release (despite the minor version bump) and came out in 2015. OpenCL 2.2 came out earlier this very year and moved C++ kernel support into the core spec, among other things.

Compute just isn't really changing that much compared to the earlier exciting days of GPGPU research. Most of the updates on any of the frameworks these days is on tooling improvements, e.g. OpenCL gaining SPIR-V and C++ support.

Thanks.

I see, as it pretty much covers the GPU architecture - which isn't really evolving that fast (I know there were quite good hardware changes like going down to 14nm in the last generation, but from the functionality point of view, there aren't any major steps). So pretty much they are just improving the actual language and support.

I will definitely google some info about OpenCL and C++ support in it (which kind of interests me), I didn't even realized they moved that far.
