This is a little warning to those of you who import HDF data, and are
upgrading to version 5.0.
In Mathematica 4.2, I had been importing HDF files like this:
Import["file.hdf","HDF",ConversionOptions->{"DatasetSelection"->3}],
referencing the dataset by number (3 in this case). In version 5, you'll
get a *different* dataset than version 4.2 if you do this. So, it's
probably best to reference the dataset by its name, like this:
Import["file.hdf","HDF",ConversionOptions->{"DatasetSelection"->"data-set-na
me"}].
This should grab the same dataset in all versions.
