+One-line Summary: Complete CCPPization of Hack shallow convection
+Github PR URL: https://github.com/ESCOMP/CAM/pull/1256
+
+Purpose of changes (include the issue number and title text for each relevant GitHub issue):
+- Convert Hack shallow convection and move to atmospheric_physics (#1174)
+
+Other changes for CCPPization that resolve issues in atmospheric_physics:
+- ZM convective mass flux (atmosphere_convective_mass_flux_due_to_deep_convection) units inconsistent with snapshot (https://github.com/ESCOMP/atmospheric_physics/issues/197)
+- Add errmsg, errflg to cloud_fraction_fice_run (https://github.com/ESCOMP/atmospheric_physics/issues/201)

+   - update atmospheric_physics to bring in Hack shallow convection,
+     and related CCPPized physics changes.

+M       src/physics/cam/physpkg.F90

+   - removal of unused second dimension (pcnst) of qpert because it is not supported
+     in CAM-SIMA snapshot reads.

+   - add errmsg, errflg to cloud_fraction_fice CCPPized scheme.
+
+M       src/physics/cam/zm_conv_intr.F90
+   - move unit conversion of convective mass fluxes to kg m-2 s-1 to
+     inside CCPPized scheme for consistency with snapshots.
+
+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.
