Description

[2026.01.01] - 2026-03-04

Known Issues

  • INTEL: Oneapi 2025.1 is currently unsupported due to an internal compiler error. The -check uninit flag for intel's LLVM compilers(ifx/icx) is also unsupported, see prior release for more information.
  • Diag Manager Rewrite: See below 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.
