The OpenMP ARB, the non-profit that owns the OpenMP brand, released the fourth version of the OpenMP API a few months ago. After a few months of use, players in the high performance compute (HPC) and digital signal processing (DSP) spaces praise the new release and have developed many products on the updated API. Upgrades available in 4.0 include accelerator support, SIMD constructs, error handling, thread affinity, tasking extensions, Fortran 2003 support, user defined reductions, and more.
