+M       .gitmodules
+          - Update atmos_phys external to bring in dme_adjust code
+
+M       bld/configure
+          - Introduce conservation_adjust subdirectory and add dme_adjust directory in it
+
+M       src/atmos_phys
+          - update submodule
+
+M       src/physics/cam/physics_types.F90
+          - changes to support calling dme_adjust from CCPP'ized code
+
+M       src/physics/cam/physpkg.F90
+M       src/physics/cam7/physpkg.F90
+          - add snapshot logic for dme_adjust
+
+
+If there were any failures reported from running test_driver.sh on any test
+platform, and checkin with these failures has been OK'd by the gatekeeper,
+then copy the lines from the td.*.status files for the failed tests to the
+appropriate machine below.  All failed tests must be justified.

+  SMS_Ld1.f09_f09_mg17.FCHIST_GC.derecho_intel.cam-outfrq1d (Overall: DIFF) details:
+    - pre-existing failures due to HEMCO not having reproducible results (issues #1018 and #856)
+
+  SMS_Lh12.f09_f09_mg17.FCSD_HCO.derecho_intel.cam-outfrq3h (Overall: DIFF) details:
+    - pre-existing failures due to HEMCO not having reproducible results (issues #1018 and #856)
+    This test actually passed this time around, but intermittently does not pass, so keeping in the list

+  SMS_D_Ln9_P1280x1.ne0CONUSne30x8_ne0CONUSne30x8_mt12.FCHIST.derecho_intel.cam-outfrq9s (Overall: FAIL) details:
+    - pre-existing failures due to build-namelist error requiring CLM/CTSM external update

+  ERS_Ln9.ne30pg3_ne30pg3_mg17.F2000dev.derecho_nvhpc.cam-outfrq9s_gpu_default (Overall: FAIL) details:
+      FAIL ERS_Ln9.ne30pg3_ne30pg3_mg17.F2000dev.derecho_nvhpc.cam-outfrq9s_gpu_default RUN time=19
+         - This job fails, but does not appear to be due to changes in the code.  Both a run made using
+	   the head of cam_development and a job run using cam6_4_079 failed in the same way.
+	   No issue has been opened yet as we expect this might be a temporary machine problem
