+PRRTE v4.x series
+=================
+
+This file contains all the NEWS updates for the PRRTE v4.x
+series, in reverse chronological order.
+
+4.0.0 -- TBD
+------------
+.. important:: This is the first release in the v4 family. The intent
+               for this series is to provide regular "reference tags",
+               effectively serving as milestones for any development
+               that might occur after the project achieved a stable
+               landing zone at the conclusion of the v3 series. It
+               is expected, therefore, that releases shall be infrequent
+               and rare occurrences, primarily driven by the completion
+               of some significant feature or some particularly
+               critical bug fix.
+
+               For this initial release, that feature is completion of
+               support for the Group family of PMIx APIs. This includes
+               support for all three of the group construction modes,
+               including the new "bootstrap" method.
+
+               Note that while PRRTE v4 will build and execute against
+               PMIx v5, proper execution of the various group construction
+               modes requires that your application use PMIx v6 or above.
+
+A full list of individual changes will not be provided here,
+but will commence with the v4.0.1 release.
