Thank you Jennifer -<br>
and COLA for these significant upgrades and keeping GrADS alive!<br>
<br>
We'll give it a trial run here. Also- will GDS be able to use this
version (and the ability for the use of it w/ RedHat5)?<br>
<br>
Thanks much- for all all your support tot he community. Glenn<br>

face="Helvetica" size="3">Because of these changes, and others that
are still in the works but haven't been implemented yet, there are some
features which we can no longer support. The UDF interface is disabled,
but will be return soon in a new implementation that should be easier
to use. The lterp() function (a widely used UDF) is now built-in. The
LATS interface is gone, but implementing a new path for writing out
netcdf with 'gxout fwrite' is very high on our to-do list. Templating
with the 'sdfopen' command is also no longer supported, and some
special cases of binary file formats are now a legacy: "var" and "z"
transposed data (units=-1,1) and "x" and "y" transposed data
(units=-1,30). The format of the GrADS metafile will also change, as
graphics improvements are implemented. The gv utility will not work
with GrADS 2.0. Otherwise, for now, everything you do with GrADS should
work in version 2. </font></div>

face="Helvetica" size="3">Binaries are for RedHatEnterpriseLinux5
(x86_64) and Intel Macs. If you are using GrADS on a unix platform of a
different flavor, I highly recommend trying to build from source, since
I will be posting updates to the source code very frequently. A list of
the required supplemental libraries is in the documentation at <a

. Almost all of these supplibs are upgrades from previous versions and
build easily. I will update this doc page with additional guidance for
building from source as soon as I can. </font></div>
