 One-line Summary: Update HEMCO interface external to HEMCO_CESM 2.1.0
 Github PR URL: https://github.com/ESCOMP/CAM/pull/1221
 
 Purpose of changes (include the issue number and title text for each relevant GitHub issue):
-HEMCO_CESM includes fixes to allow ERS tests of CAM-chem with HEMCO to pass. This requires
-a clock time bug fix in HEMCO_CESM released in new version 2.1.0 as well as an update to
-the HEMCO configuration file to read 3D emissions every timestep. Note that ERP tests will
-continue to fail with this update but will be fixed in the next version of HEMCO_CESM.
+     - Update HEMCO_CESM to get HEMCO clock time bug fix
+     - Update the HEMCO configuration file for *_HCO cases to read 3D emissions every timestep
+     - Together these updates fix failing FCSD_HCO ERS restart tests
+     - Other FCSD_HCO tests will continue to fail due to remaining reproducibility issues that
+       require a new HEMCO version to fix (https://github.com/ESCOMP/CAM/issues/856).
