I have a new Mac laptop running 10.7.1 (Lion) and the new darwin binaries work on that system too. --Jennifer

>> 2011-09-29  Version 2.0.0
>>     Features:
>>     * New shaded contouring algorithm: "set gxout shade2"
>>       Polygons are closed, have no holes, do not overlap, and are as large and few in number as is feasible
>>       Use of -1 for a color # will suppress drawing of the shaded contour, making it effectively transparent
>>     * Legacy shaded contouring routine: "set gxout shade1"
>>     * "set gxout shaded" is now an alias for legacy shaded contouring routine
>>     * Support for creating polygon shapefiles with new option "-poly" to "set shp" command
>>     * Support for creating polygon KML files with new option "-poly" to "set kml" command
>>     * 1D loglog plots with new command "set log1d"
>>     * New environment variable GASHP, contains 1 or more directories that may contain shapefiles.
>>       GASHP delimiters are space, semicolon, comma, or colon. Algorithm is:
>>         1. Tries to open filename as provided by user	
>>         2. Parses GASHP and prepends each dir to filename
>>         3. Prepends GADDIR directory (only one dir) to filename
>>     * New command "set strmopts" to control streamline density plus arrowhead spacing, size, and type.
>>       Support for negative streamline density values (between -10 and -1) for high-res grids.
>> 
>>     Misc:
>>     * Mixed case ensemble names are now allowed
>>     * Changes to improve masked contour labeling; also now works with "set vpage"
>>     * Support for grib1 time range indicator 7, which subtracts the forecast time
>>       from the basetime to get the valid time
>>     * Loosened restrictions in gribmap for mapping monthly data
>>     * Previously undocumented command: "screen"
>>     * Added "query calendar" command to discover calendar mode (unset, 365-day, or standard)
>>     * Added ":" to list of delimiters for multiple dirs in GASCRP environment variable (now same as GASHP)
>>     * Added "NULL" as an option for scale factor attribute name in the UNPACK descriptor file entry
>>       when add offset occurs alone
>>     * Updated wgrib.c to version 1.8.1.2a
>>     * Updated grib2scan to show start/ending times for averages, and valid times for instantaneous fields
>>     * Handles GRIB2 Product Definition Template 4.15
>>     * Added aliases 'line' for 'ln' and 'point' for 'pt' in 'set shp' and 'set kml' commands
>>     * Added alias 'image' for 'img' in 'set kml' command
>> 
>>     Bugs:
>>     * Fixed errors when retrieving data from a very large defined object that has more than 2Gb elements.
>>     * Patched memory leak when reading NetCDF attributes with lengths larger than 128
>>     * Patched memory leaks in cdiff(), gr2stn(), and coll2gr() functions and collect() command
>>     * Cannot have a leap and no-leap file open at the same time
>>     * Calendar mode cleared with "reinit" only
>>     * Fixed big/little endian error when reading 2-byte binary data
>>     * Fixed bug where 2-point contour segments are not drawn in upper right corner of grid
>>     * Fixed contouring bug for very high res grids with vertices too close together to resolve graphically
>>     * Fixed contouring bug for small grids that left a gap in contour line
>>     * Added check for strictly increasing contour levels
>>     * Fixed streamlines in areas where grid boxes are not square (e.g. near the poles)
>>     * Disabled erroneous vector/barb drawing in some projections (mollweide, orthographic, and robinson)
>>     * Fixed erroneous results from 'q xy2gr' for some projections (returns -999.9 instead of garbage)
>> 
>>     Supplib Updates:
>>     * Linked with jasper-1.900.1, g2clib 1.2.2, hdf5-1.8.7, netcdf-4.1.3, zlib-1.2.5
