Aside from offering support for 7th Generation Core "Kaby Lake" processors and Windows 10 Anniversary support, there are a number of interesting Linux changes. Linux work in this release includes Yocto support, OpenCL 2.1 and SPIR-V support, hardware counters support on Linux, and latency analysis support for Skylake/KabyLake CPUs.
The OpenCL 2.1 support is experimental CPU-only runtime support for OpenCL 2.1 workloads. The SPIR-V generation support is via Intel Code Builder for OpenCL.
While it's nice that Intel provides OpenCL 2.1 / SPIR-V support for Linux, unfortunately this OpenCL software is closed-source. The Beignet project from Intel's Open-Source Technology Center has yet to support OpenCL 2.0 even nor SPIR-V.
