NEWS: Update bullet about PMIx improvements.
Per the call/discussion today, we want to make it clear that the improvements are only when you are actually using PMIx (via mpirun-based launches and when using a RM that utilizes PMIX [vs. PMI-2 or the like]). Signed-off-by: Jeff Squyres <[email protected]>
