OpenMP 4.0 Majorly Advances Parallel Programming
Phoronix: OpenMP 4.0 Majorly Advances Parallel Programming
The OpenMP 4.0 specification has been unveiled as a major new specification for programming of accelerators, SIMD programming, and better optimization using thread affinity...
It's also the one the LLVM teams have targeted as their priority for OpenMP, so pre-existing 3.x is not in the cards.
Not necessarily a bad thing if OpenMP 4 doesn't support all of OpenMP3. Just give it a clean slate, no legacy cruft to have to support or work around.
