But this is by design, because we’re not supposed to add new features (especially API-changing or module-changing ones) in a release branch. The compatibility fixes you propose will increase the complexity of the module reader code, and creates some precedent. I don’t think there’s much pressure from the “general public” for Fortran OpenMP 4.0, so having it in 4.10 only rather than 4.9 is probably not such a big deal. FX
