I'm sure we've gotten a few questions and complaints, but tools in the
current release handle both netCDF-3 and netCDF-4 files, and we would
recommend recompiling/relinking the tool with the current version of the
library.  If the netCDF-4 file uses the classic data model, that fixes
the problem.  If the netCDF-4 file uses new features of the enhanced
data model, modifications to software linked to an older netCDF-3
library will be required.

We've publicly committed to maintaining API and format compatibility
going forward:
