Full Changelog: v4.6.1...v4.6.2-rc1-tmp

4.6.1 - May 19, 2023

Requirements

• netCDF-C: 4.9.0+

Note: to enable libzstd support, you need to satisfy the following requirements.

1. libnetcdf.so installed with libzstd support.
2. The environmental variable HDF5_LIBRARY_PATH needs to be specified to the same location used when installing libnetcdf. This can be determined after-the-fact using nc-config --plugindir.

Notable Changes

• We've added API support to take advantage of the Quantize functionality provided by libnetcdf 4.9.0+. See this conversation for more information.

4.5.3 - June 2, 2020

Requirements

• netCDF-C: 4.7.4+

Changes

• Adds a libnetcdff.settings file similar to libnetcdf.settings. See Github #256 for more information.
• Added support for gcc/gfortran 10. The -fallow_argument_mismatch flag is passed to the underlying compiler when the flag is found to be supported. This change has been added to the autotools and cmake based builds. See GitHub #212 for more information.
• Added support for HDF5 compact storage. See Github #213.
• Added support for creating netCDF/HDF5 files with szip compression with new functions nf90_def_var_szip() and nf_def_var_szip(). See Github #213.
• Corrected an issue where parallel netCDF-Fortran builds would fail despite the presense of MPI libraries/compiler/infrastructure. See Github #208 for more information.

Requirements

• netCDF-C: 4.6.0 or greater

Changes

• Corrected an issue where netCDF-Fortran would fail to build correctly on some platforms when the underlying libnetcdf lacked netCDF-4 support. See GitHub #200 for more information.
• Corrected an issue where cmake-specific large file tests weren't being captured by make dist. See Github #198 for more details.

Requirements

• netCDF-C: 4.6.0 or greater

Changes

• Corrected an issue where a cmake-specific file wasn't being captured by make dist.
• Corrected an issue where nf-config wasn't being generated by cmake-based builds. Corrected a couple of other missing files. See Github #108 for more information.

• Moved netCDF classic F90 API tests to new subdirectory nf03_test.
• Moved netCDF-4 F77 API tests to new subdirectory nf_test4.
• Moved netCDF-4 F90 API tests to new subdirectory nf03_test4.
• Fixed bug which caused parallel I/O tests to not be run. See #155 and #157.
• Fixed bug in the setting of file cache preemption for netCDF-4 files. See #146.
• Removed many near-duplicate tests files, now they are created at build time with sed. See #165.
• Removed no longer needed configure options --enable-dll (see #161), --enable-extra-tests (see #114), --enable-extra-example-tests(see #126), and --enable-valgrind (see #118).
• Moved handling of F77 man page to the docs directory. See #141

A maintenance release, with the next push being to clean up the issues related to netCDF-Fortran.

Requirements

• netCDF-C: 4.6.2

Changes

• Assorted bugfixes.
• Interface for working with user-defined plugin API in netCDF-C.
• Added an option in cmake builds, BUILD_EXAMPLES, TRUE by default. When disabled, the examples will not be built. See #93 for more information.
• Misc. Bugfixes to bring netCDF-Fortran in line with the features in netCDF-C.
• Updated CMakeLists.txt to check for C types that match Fortran ones. See GitHub #67 for more information.

4.4.4 Released May 13, 2016

• Corrected an issue where cmake-based builds specifying USE_LOGGING were not seeing expected behavior. The issue was reported, and subsequently fixed, by Neil Carlson at Los Alamos Nat'l Laboratory. See Github Pull Request #44 for more information.

• Integrated improvements provided by Richard Weed. For a complete list of modifications, see the file docs/netcdf_fortran_4.4.2dev_notes_RW.pdf. It is highly detailed and worth reading!

  The highlights of the improvements are as follows:

  • Explicit dependencies on NC_MAX_DIM constant for arrays has been removed and replaced with dynamically-allocated arrays.
  • Support for nc_open_mem() in the C library, allowing for the creation of "in memory" files.
  • General clean up.
