+
+Purpose of changes (include the issue number and title text for each relevant GitHub issue):
+- Update MPAS-A within CAM to 'v8.2.1'  https://github.com/ESCOMP/CAM/issue/1144
+
+Describe any changes made to build system:
+
+Describe any changes made to the namelist:
+
+List any changes to the defaults for the boundary datasets:
+
+Describe any substantial timing or memory changes:

+List all files eliminated:
+
+List all files added and what they do:
+
+List all existing files that have been modified, and describe the changes:
+M       .gitmodules
+ - Update the mpas fxTag to v8.2.1
+
+M      src/dynamics/mpas/Makefile
+ - Add rules to build stream_inquiry and mpas_stream_inquiry
+ - Pass CPPFLAGS to the registry command
+ - Edit CPPFLAGS: add MPAS_BUILD_TARGET and add the GIT_VERSION using a shell command
+ - Also a commented out addition to enable mpi_f08 support in MPAS
+
+M      src/dynamics/mpas/driver/cam_mpas_subdriver.F90
+ - Add streamInfo to the MPAS domain_ptr
+ - Modify function calls for updated variables
+ - Optional mpi_f08 change
+
+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.
