Howdy John!

It is I who should be sheepish! That was a simple HTML error on my part.

FYI the HDF5 snapX releases come *after* the numbered release, so 1.8.3-snap2 
was the second snapshot release after the 1.8.3 release (and on the way to the 
1.8.4 release).

There was a bug in HDF5-1.8.3 relating to nested user-defined types. The bug 
was found here at NetCDF World HQ, and forwarded on to the underground bunker 
complex in which the HDF5 programmers work 24/7 answering our email. The fix 
made it into the 1.8.3-snap2 and later releases of HDF5.

The HDF5 team is about to release 1.8.4 and I've upgraded our snapshot web page 
to the 1.8.4-pre1 release of HDF5. 

If we were all very good this year, the HDF5-1.8.4 release and the netCDF-4.1 
release will be out in time for Christmas, and we can play with them on 
Christmas morning! ;-)

Thanks,
Ed
