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
