Hi Sean-
It looks like thredds.ucar.edu is working again for bundles, however I
have a question about the new catalog entries.
From the IDV catalog chooser, I don't see a "Latest" entry that works.
For example, if I select the:
Latest Reference Time Collection for GFS-CONUS 80km-CONUS 80km
All I get is a single time and when I try to load that, I get an error.
How do I get the "Latest" under TDS 4.5 like I could in all previous
versions?
Also, each model grid shows up as a catalog and in that folder is a
single entry for the file. It seems like things are getting more
complicated rather than easier.

Greetings!
The TDS server thredds.ucar.edu has been updated to version 4.5. Part of
the move is related to security concerns raised over the past month, and
part is due to the unreliability of GRIB collections to update properly
in the old version (4.3.21). There are also several improvements and
bugfixes in 4.5.
For the IDV, this update will mostly improve access to GRIB data served
from Unidata (no more "permission denied" issues, no more stale files,
etc.).
Bundles
=======
Bundles that use thredds.ucar.edu should not be impacted, as the urls to
the latest and best time series files/collections are the same. None of
the variable names should have changed, unless it is due to an updated
GRIB-1/2 table.
Browsing thredds.ucar.edu
=========================
You may notice a few differences in the way data are displayed. Some of
them are temporary (such as datasets being listed from oldest to newest
- this will be reversed asap), while others not. For example, there is a
new dataset listed under GRIB collections called "Full Collection
(Reference / Forecast Time) Dataset". This dataset contains two time
coordinates, and allows for slicing and dicing similar to the "constant
forecast offset" and "constant forecast hour" from the older, deprecated
FMRCs. Currently, the IDV cannot take advantage of these collections,
but we hope to enable them in the near future.
If you have any questions, or run into any bugs, please contact
support-idv@xxxxxxxxxxxxxxxx or support-thredds.unidata.ucar.edu.
Cheers!
Sean
