[thredds] Announce: TDS 4.1 alpha 1 release

[Ethan Davis <edavis@xxxxxxxxxxxxxxxx>]

Hi all,

Our first alpha release of TDS 4.1 is now available from the web page

http://www.unidata.ucar.edu/projects/THREDDS/tech/TDS.html

Please test but, for now, do not replace your mission-critical
servers.

The main differences are:

- Improved handling of GRIB ensemble data (including a new GRIB index
format).
- Improved handling of the various PointObs feature types.
- Improved tracking of dataset collections (used in aggregation and
PointObs collections).

Thanks,

Ethan (and John and Robb)
