NetCDF 4.6.1

Version 4.6.1 of the netCDF-C library is now available. This is primarily a maintenance release; highlights include:

• Reverted some new behaviors that, while in line with the netCDF specification, broke existing workflows.
• Corrected an issue which could result in a dap4 failure.
• Allow nccopy to control output filter suppresion.
• Improved support for CRT builds with Visual Studio, improves zlib detection in hdf5 library.
• Moved HDF4 into a distinct dispatch layer.

Note that due to ongoing issues, native CDF5 support is disabled by default. (See the Release Notes section describing release 4.5.0-rc3 for information on how to enable CDF5 support.) You should be aware that for the time being, reading/writing CDF5 files on 32-bit platforms may result in unexpected behavior when using extremely large variables. For 32-bit platforms it is best to continue using NC_FORMAT_64BIT_OFFSET.

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.
