Howdy all!
Deep in the vast underground complex of the Unidata Program Center,
beneath the floors packed with water, food supplies, and weapons, past
all the blast doors and security checkpoints, and surrounded by
lead-lined cement walls four feet thick, the netCDF developers continue
to program new features into the netCDF C/Fortran libraries.
Our work is periodically shipped up to the surface, and released to the
world in the daily snapshot of netCDF:
ftp://ftp.unidata.ucar.edu/pub/netcdf/snapshot/netcdf-4-daily.tar.gz.
There have been many changes since the 4.0.1 release last March, and
users interested in any of the new features should grab a copy of the
daily snapshot and check them out.

VERSION COMMENTS
------- --------
4.1 2009-??-??
Added libcf library to netCDF distribution. Turn it on
with configure option --with-libcf.
Added capability to read HDF4 files created with the
SD (Scientific Data) API.
The DAP support was revised to closely mimic the
original libnc-dap support.
Significantly revised the data handling mechanism
in ncgen4 to more closely mimic the output from the
original ncgen.
Added prototype NcML output capability to ncgen4.
It is specified by the -lcml flag.
Added capabilty to read HDF5 files without dimension
scales. This will allow most existing HDF5 datasets to
be read by netCDF-4.
Fixed bug with endianness of default fill values for
integer types when variables are created with a
non-native endiannesss and use the default fill value.
Significant refactoring of HDF5 type handling to
improve performance and handle complicated nesting of
types in cross-platform cases.
Added UDUNITS2 to the distribution. Use --with-udunits
to build udunits along with netcdf.
Made changes suggested by HDF5 team to relax
creation-order requirement (for read-only cases) which
allows HDF5 1.6.x files to be retrofitted with
dimension scales, and be readable to netCDF-4.
Handle duplicate type names within different groups in
ncdump. Fix group path handling in absolute and
relative variable names for "-v" option.
Added nc-config shell script to help users build
netCDF programs without having to figure out all the
compiler options they will need.
As always, please send any questions or comments to
support-netcdf@xxxxxxxxxxxxxxxx.
Thanks!
