    libgomp/ChangeLog
            * libgomp.texi (OpenMP 5.0): Mark metadirective and declare variant
            as implemented.
            (OpenMP 5.1): Mark target_device as supported.
            Add changed interaction between declare target and OpenMP context
            and dynamic selector support.
            (OpenMP 5.2): Mark otherwise clause as supported, note that
            default is also still accepted.
