NetCDF 4.7.1

03 September 2019

Version 4.7.1 of the netCDF-C library and version 4.5.1 of the netCDF-Fortran library are now available.

netCDF-C

Changes in the netCDF-C library include (but are not limited to):

Added unit_test directory, which contains unit tests for the libdispatch and libsrc4 code (and any other directories that want to put unit tests there). Use —disable-unit-tests to run without unit tests (ex. for code coverage analysis).
Removed obsolete _CRAYMPP and LOCKNUMREC macros from code. Also brought documentation up to date in man page. These macros were used in ancient times, before modern parallel I/O systems were developed. Programmers interested in parallel I/O should see nc_open_par() and nc_create_par().
Removed obsolete and deprecated functions nc_set_base_pe() and nc_inq_base_pe() from the dispatch table. (Both functions are still supported in the library, this is an internal change only.)
Reverted nccopy behavior so that if no -c parameters are given, then any default chunking is left to the netcdf-c library to decide.

Detailed information about the release is available in the Release Notes.

Complete information about using this release can be found in the NetCDF Documentation.

Source-code zip and tar.gz archives can be found on Unidata's NetCDF-C GitHub site.

Pre-built Windows binaries for use with Visual Studio) are available from this page.

netCDF-Fortran

The netCDF-Fortran library version 4.5.1 requires the netCDF-C library version 4.6.0 or greater. Changes in this release include (but are not limited to):

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.
Fixed bug in the setting of file cache preemption for netCDF-4 files.
Removed many near-duplicate tests files, now they are created at build time with sed.
Removed no longer needed configure options —enable-dll, —enable-extra-tests, —enable-extra-example-tests, and —enable-valgrind.
Moved handling of F77 man page to the docs directory.
