Hi, Everybody!
<div class="">Brian and I are happy to present GrADS version 2.2.0. The new release merits a significant uptick because it merges the graphics capabilities from versions 2.0 and 2.1 and all the available graphics engines are now handled as plug-ins. You can
choose at startup which rendering engine you’d like to use for interactive display and printing (defaults are Cairo). Documentation may be found <a href="http://cola.gmu.edu/grads/gadoc/plugins.html" class="">here</a> — please read the whole page.</div>
<div class=""><br class="">
</div>
<div class="">The <a href="http://cola.gmu.edu/grads/downloads.php" class="">GrADS download page</a> has links to the source code, and pre-compiled binary distributions for three flavors of unix. I built the binary distributions on COLA’s servers (CentOS7),
and at NCAR on yellowstone (rhel6) and cheyenne (suse12). I will post a build for Mac OS X as soon as I can. </div>
<div class=""><br class="">
</div>
<div class="">Those of you who build from source will find changes in the configure scripts to support the building of shared objects for the graphics plugins. The organization of the supplibs is a little different as well. Please see
<a href="http://cola.gmu.edu/grads/gadoc/supplibs2.html" class="">http://cola.gmu.edu/grads/gadoc/supplibs2.html</a> for guidance on building from source. </div>

<div class="">Other features of this build are itemized in the complete <a href="http://cola.gmu.edu/grads/ChangeLog" class="">ChangeLog</a>, and also copied below for your convenience. </div>
<div class="">Don't be afraid to upgrade! </div>

<pre class=""><font size="3" class=""> Features:
* Graphics display and printing are now handled as independent plug-ins.
Cairo is the default, but the traditional X11 display (with widgets) and
the old GD interface for image output are available as user-specified options.
There is also no-op gxdummy plug-in for when no graphics capabilities are needed.
* New arguments on startup for specifying graphics plug-in names (-d and -h)
* New requirements for the User-Defined Plug-in Table: gxdisplay and gxprint
* Overhaul of auto configuration protocol to support creation of shared libraries
for the graphics plug-ins.
* Added command 'q udpt' that lists all available plug-ins
* Added command 'q gxconfig' that reports the configuration of graphics plug-ins
* Updated the output from the 'q config' command
* New command 'q font' returns information about a specific font
* Added support in grib2scan to print model version date for PDTs 60 and 61
* Added optional argument to 'q dbf' to specify a delimiter other than ","
* Increased max number of block requests to raise limit on station data memory usage
Bug Fixes:
* Fixed bug to use an 8-byte integer to store a variable's offset in a file
* Fixed bug in new shaded contour algorithm when plotting a range beyond the
data maximum and csmooth is on.
* Fixed routines handling netcdf4 cachesize so it resets if user adjusts scale factor
* Fixed mismatched max length of variable description in descriptor files
* Fixed bug when drawing zero-sized strings with Cairo

Supplibs Update:
* Simplified the protocol for building, installing, and checking the supplibs
in conjunction with changes to auto configuration scripts.
* New documentation page: <a href="http://cola.gmu.edu/grads/gadoc/supplibs2.html" class="">http://cola.gmu.edu/grads/gadoc/supplibs2.html</a>
* Updated the gadap library to version 2.1 to add support for a shared object
and some minor fixes for compilation on newer versions of unix.
* Linked with pixman-0.34.0 and cairo-1.14.10</font></pre>
