[2021.04] - 2021-12-23

Known Issues

• GCC 11.1.0 is unsupported due to compilation issues with select type. The issue appears to be resolved in later GCC releases

Added

• PARSER: Adds a parser using the libyaml C library to support yaml format input files.
  Currently implemented in data override and can be enabled with the configure option --with-yaml or with CMake option -DWITH_YAML
• FMS: Adds an interface, fms_c2f_string, to convert C strings and C pointers to Fortran strings
• MPP: Adds a routine mpp_shift_nest_domains and a field to nest_domain_type to allow for modifying the position of a given nest domain
• FMS2_IO: Reintroduces the option to flush_nc_files with fms2_io

Changed

• DIAG_MANAGER: Cleans up IO code and replaces any remaining dependencies to mpp_io with fms2_io
• FMS_IO: Changes to allow for custom paths for namelists, field_table, and the INPUT directory
• EXCHANGE: Changes real sizes in xgrid and gradient modules to be explicitly r8_kind to prevent runtime issues with mixed precision

Deprecated

• MPP: get_unit has been deperecated in favor of the Fortran intrinsic newunit and will now generate a warning if used

Removed

• TIME_MANAGER: Removes deprecated array-based gregorian calender calculations that were replaced in 2021.02

Fixed

• DIAG_MANAGER: Fixes issues with 3D diurnal diagnostic output and removes a redundant write_data call
• TIME_INTERP: Fixes load_record read_data call for 3d variables with fms2_io and eliminates redundant data loading and validity checking for on-grid interpolations.
• MPP: Fixed a bug with non-blocking domain updates failing on GNU compilers from uninitialized values
• MPP: Fixed issues with the mpp_type_free function causing errors and memory leaks when freeing the mpp_byte type
