[2021.03] - 2021-08-16 Known Issues DIAG_MANAGER: 3D diurnal diagnostic variables are not supported in this version of FMS ### Added FMS2_IO: Documentation was added for FMS2_io to help users convert from fms_io/mpp_io ### Changed FMS2_IO: The error messages in FMS2_io were updated to give more useful information TEST_FMS: The unit tests in mosaic, axis_utils, and time_interp_external were updated to use the FMS2_io version of these routines and are no longer skipped DOCS: The doxygen generated documentation has been improved with more doxygen comments added and a more cohesive layout TEST_FMS: Unit tests for time_manager were updated to use the new get/set_date_gregorian routines ### Removed MPP_IO: The namelist variable use_mpp_io was removed from interpolator, amip_interp, diag_manager, topography, xgrid, and data_override MPP_IO: Any remaining fms_io/mpp_io calls from the source and test code were removed FMS: Removes the hardcoded path for input.nml, path now may be specified in the call to fms_init ### Fixed MPP: Fixes algorithm used with nested grid updates to properly coalesce x-dir and y-dir pelists for vector quantities CMAKE/AUTOTOOLS: Fixes for minor issues with filenames in both the CMake and autotools build systems MPP: Restored deleted pset functionality needed by GFDL SCM by reinstating mpp_pset.F90 MPP: Fixed uninitialized variables for data domains in mpp domains broadcast routines MPP: Minor memory leaks from deallocating domains AXIS_UTILS: Fix PGI related error with string length sizes ### Tag Commit Hashes 2021.03-beta1 (6d6ff9595ede12ea0a342ae014442708a27041d2) 2021.03-alpha1 (87d945d8dba6341f1f56631047ae5d3e5b4ab828
