 One-line Summary: New single column functionality for the NUOPC cap
 
 Purpose and description of changes
 ----------------------------------
 
+Implemented new nuopc/cmeps single column functionality.
+
+In config/cesm/config_files.xml - single point domains are only used 
+for mct/cpl7. For cmeps single point meshes are now generated on the 
+fly and component domains files are no longer needed.
+env_run.xml variables PTS_LAT, PTS_LON and PTS_DOMAINFILE are used 
+to determine if there is a single point or single column run.
+If PTS_LAT and PTS_LON are not -999 and PTS_DOMAINFILE is UNSET, 
+then you have a single point run and the exact values of PTS_LAT
+and PTS_LON are used.  If PTS_LAT and PTS_LON are not -999 and 
+PTS_DOMAINFILE is not UNSET, then then the cmeps driver will recognize the nearest neighbor
+values of PTS_LAT and PTS_LON in PTS_DOMAINFILE as the single column lat and lon to use.

 Notes of particular relevance for developers:
 ---------------------------------------------
 NOTE: Be sure to review the steps in README.CHECKLIST.master_tags as well as the coding style in the Developers Guide
 [Remove any lines that don't apply. Remove entire section if nothing applies.]
 
 Caveats for developers (e.g., code that is duplicated that requires double maintenance):
+  Nine step tests changed so that they have ROF run at same frequency as ATM (like the similar CAM tests)
+  as these will fail with NUOPC since it doesn't allow you to end not on an even time-step for all components.
+  One of these tests changed to a CAM type test from decStart
