Additional information is available from the NetCDF-Java documentation page.

About this version

Version 4.3.21 fixes a bug when reading netcdf-4 chunked files.

Note on version 4.3 handling of GRIB files

Version 4.3 includes a complete rewrite of GRIB1 and GRIB2 file handling, intended to correct problems that exist in version 4.2's handing of tables (especially in non-NCEP files) and time interval coordinates.

Note: The variables in a GRIB dataset will have different names when viewed in CDM 4.3 than the same variables when viewed in CDM 4.2. If your application reads GRIB files, we strongly recommend that you upgrade to the latest version of the NetCDF-Java/CDM library and closely examine the output of any files that you really care about. Check parameter names and everything else against the original documentation if possible, especially if there is any local parameter use. Please send us any files you suspect might be incorrectly read by the CDM library.

Evolving documentation for GRIB is at Unidata's Grib Tables page.

The NetCDF-Java development team at the Unidata Program Center strongly encourages operators of sites that take advantage of the CDM libraries to install the latest version and forward any potential issues to the development team via Unidata's support system (support-netcdf-java@unidata.ucar.edu) or the user community mailing list (netcdf-java@unidata.ucar.edu). Real-world use of new features by the user community is integral to the process of creating and refining these libraries.

Comments:

Is this the version that is available on the download page? The dates still say Nov 25

Yes, the current version is available on the download page. The release date shown on that page was incorrect, but has been updated. Thanks for noticing!
