There are updates to the HDF, HDF5, and CDF libraries available,
but they are downloaded and installed separately -- they don't come
as part of the 7.0.3 workbench update. To get the library updates,
you'll need to log in to the ITTVIS web site and navigate to the IDL
product downloads page and look for the

"IDL 7.0.3 Scientific Data Formats"

patch installer for your platform. Note that there are only two
changes to the API: the addition of the CDF_SET_MD5CHECKSUM
routine and the addition of the READONLY keyword to the CDF_OPEN
routine. All other changes to the libraries should be transparent to
IDL code.

Since the scientific data format libraries are third-party code and
packaged in dynamically loadable modules, they can be updated
separately from the IDL's core functions, and sometimes are.

If you have pro code that relies on a specific version of a third-
party
library like HDF or HDF5, in general you'd be much safer to use the
library's own version information mechanism. See

CDF_LIB_INFO
H5_GET_LIBVERSION
HDF_LIB_INFO
EOS_EH_GETVERSION

in the help if you're specifically interested in the recently updated
libraries. (I'm not aware of a way to check the version of the NetCDF
library from within IDL.)

I hope that's helpful,
Doug
