PRRTE v4.x series
=================

This file contains all the NEWS updates for the PRRTE v4.x
series, in reverse chronological order.


4.0.0 -- 19 May 2025
--------------------
.. 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.
