[2025.01] - 2025-01-30

Known Issues

• Diag Manager Rewrite: See the changelog for known output file differences regarding the new diag manager. The new diag_manager is disabled by default, so these differences will only be present if use_modern_diag is set to true in the diag_manager_nml.
• BUILD(HDF5): HDF5 version 1.14.3 generates floating point exceptions, and will cause errors if FMS is built with FPE traps enabled. FPE traps are turned on when using the debug target in mkmf.
• GCC: version 14.1.0 is unsupported due to a bug with strings that has come up previously in earlier versions. This will be caught by the configure script, but will cause compilation errors if using other build systems.
• INTEL: The -check uninit flag for the Intel Oneapi Fortran compiler (ifx) is unsupported due to a bug causing false positives when using external libraries. If using the -check all flag, -check all,nouninit should be used instead.

Added

• ENSEMBLE YAML SUPPORT: Adds functionality to the diag_manager, field_manager, and data_override to support unique yaml tables for each member of an ensemble or nest. More information can be found in in the diag_manager and data_override README files (#1585)
• BUILD: Adds options to set PORTABLE_KINDS macro in CMake and autotools builds (#1572)
• BUILD(autotools): Adds check for cray compiler .mod file capitalization and will now run a previously added, but unused, m4 check for newunit support. (#1561)
• BUILD(cmake): Adds CMake functionality to generate a pkgconfig file (#1565)
• DIAG_MANAGER: Modifies diag_field_add_attribute to accept both r4 and r8 values (#1625)

Changed

• MPP_IO/FMS_IO: A deprecation warning will now be output when using these modules or enabling the -Duse_deprecated_io flag via the build systems. Usage of these modules will be deprecated in the next release. (#1609)
• DIAG_MANAGER: Made changes to the reduction routine to improve performance of loop and to reduce unnecessary calls if there isn't any new data to process (#1634)
• MOSAIC/GRID_UTILS: The mosaic directory has been refactored and is now called grid_utils. (#1626) As part of these updates:
  • The create_xgrid.c/h files have been moved to the horiz_interp/include directory
  • Any any unused .c/.h files or functions from mosaic have been removed
  • C functions have been moved between the grid_utils.c, tree_utils.c and create_xgrid.c files depending on the functions usage
• DIAG_MANAGER: Changes fms_diag_accept_data from a function to a subroutine (#1610)

Fixed

• DIAG_MANAGER: Fixes functionality of the new_file_freq, start_time, and file_duration keys in the diag_manager. (#1633)
• MOSAIC2: Fixes argument intent for calc_mosaic_grid_area and makes changes to the test to avoid divide-by-zero errors (#1597)
• YAML_PARSER: Fixes incorrect argument type in c-binding causing type mismatch errors with the cray compiler (#1580)
• BUILD(CMake): Removes usage of hardcoded lib directory path (#1589)
• HORIZ_INTERP: Adds allocation checks before checking fields for horiz_interp_type_eq (#1584)
• BUILD: Fixed syntax error in column_diagnostics Makefile.am (#1598)
• DIAG_MANAGER: Adds a workaround for a cray compiler bug where the NULL() intrinsic causes a type mismatch when passed in as an argument (#1560)
• LIBFMS: Adds missed f2c_string routine to libFMS.F90 (#1601)
• BUILD(autotools): Fixes false ./configure failures when using intel compilers and the -warn flag (#1583)
• BLOCK_CONTROL: Updates non-uniform block size warning to only output on the root pe (#1588)
• FMS2_IO: Fixes z-axis domain reads when edge lengths and corners are specified (#1620)
• MPP: Fixes temporary array compiler warning during mpp_init (#1628)
• SAT_VAPOR_PRES: Fixes bad temperature output not printing on non-root pe's (#1619)
• ASTRONOMY: Adds allocation checks for module variables before being deallocated in astronomy_end (#1629)
• TESTS: Fixes multiple unit test failures, including any failing tests when compiled with GNU debug flags (#1575, #1595, #1579, #1607, #1622)
• TESTS: Fixes multiple compilation and runtime errors from the unit tests when compiled with the cray compiler (#1599, #1602, #1603, #1604, #1605)
• TESTS: Replaces usage of fms_platform.h includes with platform_mod in mpp unit tests (#1616)
• TESTS: Add workaround for ifx failures in diag_integral and topography tests (#1606)
