While there's been a draft specification of OpenMP 4.1 out for public review since July and compiler developers have already been implementing OpenMP 4.1 support, this next version of the API for parallel programming is now going to be called OpenMP 4.5.

Given the number of changes since OpenMP 4.0, the OpenMP developers have decided to re-brand OpenMP 4.1 as OpenMP 4.5. Some of the changes expected for this next version of OpenMP is initial task priorities support, initial support for memory affinity, increased Fortran 2003 support, OpenMP device construct improvements, improved support for C++ reference types, a new taskloop directive, and new features to handle dependences within loops.

With GCC developers already have been working on OpenMP 4.1 support for months, Red Hat's Jakub Jelinek sent out the big renaming patch in a mailing list thread entitled, "OpenMP 4.1 is dead, long live OpenMP 4.5."

This next OpenMP specification is expected to be officially released before SC15 next month. OpenMP 5.0 meanwhile is in development for release in hopefully 2017.
