+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.
