Warning

Please note:

  • The Python 2 interface will be removed in Q1 2023. Users are strongly advised to migrate to Python 3.

  • We have added an experimental CMake option to allow compilation with a C++ compiler. To enable this, pass the following to the cmake command:
    -D ENABLE_EXPERIMENTAL_BUILD_WITH_CXX=ON
    This option is disabled by default.

Changes for Version 2.27.0:

New Features/Improvements

  • Performance enhancements
    • [ECC-1403] - GRIB: codes_grib_nearest_find too slow
    • [ECC-1427] - GRIB Performance: Improve decoding speed of CCSDS packing
    • [ECC-1422] - BUFR performance: Reduce number of dynamic memory allocations

  • [ECC-1405] - Add new function: codes_handle_new_from_samples
  • [ECC-1413] - GRIB2: add iteration key in the MARS namespace for stream=elda, type=4i

...

  • [ECC-1054] - bufr_dump error with unsupported operator 54
  • [ECC-1388] - GRIB2 CCSDS: Unpacked values different from simple packing
  • [ECC-1392] - Fortran interface: codes_open_file fails if the filename has spaces
  • [ECC-1395] - BUFR: Encoding should fail if attempting to encode message with an undefined element descriptor
  • [ECC-1396] - Clang -fsanitize=undefined: runtime errors during tests
  • [ECC-1397] - Tools: grib_ls nearest neighbour with JSON output

  • [ECC-1407] - grib_set -r -s packingType=grid_simple does not preserve accuracy on input packingType=grid_ieee
  • [ECC-1410] - GRIB: C API: keys iterator name is NULL
  • [ECC-1414] - GRIB: Nearest neighbour does not work for PNG packing
  • [ECC-1416] - GRIB: Setting computed key firstSize to 3e-8 sets wrong coded keys
