+Release 1.1.1:
+By John A. Magliacane, <kd2bd@amsat.org> (01-Apr-2006):
+
+* An srtm2sdf utility was added to permit SPLAT Data Files to be
+ derived from the latest 3-arc second SRTM (STS-99 Space Shuttle
+ Radar Topography Mission) digital elevation model data. The
+ quality of this data is *significantly* higher than that of older
+ USGS Digital Elevation Models previously used by SPLAT!. Despite
+ the higher quality, some voids in SRTM data sets still exist.
+ When voids are detected, the srtm2sdf utility replaces them with
+ equivalent elevation data found in existing SDF files (presumably
+ generated from older USGS elevation models). If older SDF files
+ are not available, voids are handled through pixel averaging or
+ direct replacement.
+
+* Coding changes were made that in concert with the new srtm2sdf utility
+ should allow SPLAT! to function over all regions of the planet for
+ which SRTM-3 elevation data is available.
+
+* SPLAT's SDF search path priority has been changed. SPLAT! now
+ searches for needed SDF files in the current working directory first.
+ If the needed file isn't found, SPLAT! then searches in the path
+ specified by the -d command-line option, or in the $HOME/.splat_path
+ file.
+
+* The color scheme used by SPLAT! in the generation of Longley-Rice
+ path loss maps was noticeably improved.
+
+* A new command-line option (-db) was added to allow constraints
+ to be placed on the maximum attenuation contours plotted on
+ path loss maps.
+
+* A possible array overflow condition in the ReadPath() function was
+ identified and fixed.
+
+* Some very slight coding modifications were made to permit warning-free
+ compilation under GCC 4.x.x.
+
+* The usgs2sdf utility was modified John Gabrysch (jgabby@gmail.com) to
+ properly handle the latest USGS DEM file format, and to properly scale
+ Alaska tiles.
