+Release 1.2.1:
+By John A. Magliacane <kd2bd@amsat.org> (18-Oct-07):
+
+* SPLAT! now imports transmitter effective radiated power information and
+ predicts received field strength signal levels (dBuV/m) and antenna
+ voltage based on the transmitter's antenna pattern, computed path loss,
+ and ERP. ERP information is specified on the ninth line of SPLAT! .lrp
+ files.
+
+* The ability to plot signal strength contour maps has been added. The
+ color schemes for plotting signal strength and path loss contour maps
+ can now be customized by editing the contents of .scf and .lcf files
+ for each transmitter site. In addition, both signal strength and path
+ loss contour maps can now be generated for multiple transmitter sites,
+ with the greatest signal strength (or least path loss) illustrated in
+ overlapping regions between sites.
+
+* A new -ngs switch assigns all topography to the color white in .ppm
+ contour maps. The white background can be made transparent using
+ simple graphics utilities for merging SPLAT! contour maps with other
+ Mercator projection maps and graphics files of equivalent size and
+ resolution.
+
+* Path loss and signal strength contour regions can now be exported to
+ Google Earth as a semi-transparent ground overlay using the -kml switch.
+
+* The default contour map filename now defaults to the basename of the
+ transmitter site .qth file (or first transmitter site within a network)
+ with a .ppm extension (rather than "map.ppm").
+
+* The Fresnel zone clearance percentage, which was fixed at 60% in the
+ past, is now user-definable using the new -fz command-line option.
+
+* Information previously contained in SPLAT! Obstruction Reports has now
+ been merged with Longley-Rice path loss information into a single Path
+ Analysis report (with a .txt extension). (Longley-Rice output (.lro)
+ files are no longer generated.)
+
+* Graph plotting (the -l option) no longer needs to be forced to perform
+ a Longley-Rice path analysis in point-to-point mode. If a .lrp file is
+ available and contains the information needed, Longley-Rice path loss
+ information will be automatically included in SPLAT!'s Path Analysis
+ Report when performing a point-to-point analysis.
+
+* In addition to information previously contained, SPLAT! Path Loss Output
+ (-plo) files now contain additional information including path loss
+ considering the effects of the transmitting antenna's radiation pattern
+ (if pattern data is available), and field strength values (dBuV/m)
+ based on pattern data and ERP data (if available). An asterisk at
+ the end of each line indicates the path to the point referenced in
+ the file is obstructed by terrain.
+
+* The srtm2sdf utility now handles 3-arc second SRTM in .BIL (Band
+ Interleaved by Line) format, as well as the usual .HGT format.
+
+* SPLAT!'s associated itm.cpp file was updated to include the latest
+ public domain ITM code released on June 26, 2007.
+
+* References in source code and documentation to "slots" and "MAXSLOTS"
+ have been changed to "pages" and "MAXPAGES", respectively.
* Two bugs affecting the plotting of Fresnel zones were identified and fixed.
* Text documentation in Spanish was added (thanks to Charles Esobar).
+* The build scripts were modified to permit successful compilation with
+ bzip2-1.0.4 libraries. (Thanks to Janek, SQ5MJL)

----------------------------------------------------------------------------
Release 1.2.0:
* Support for user-defined terrain files (ground clutter) has been
added.
-* SPLAT! can now generate .geo Georeference Information Files
+* SPLAT! can now generate .geo Geo-reference Information Files
when .ppm topography and coverage maps are created, permitting
the integration of SPLAT! generated maps with X Amateur Station
Tracking and Information Reporting (www.xastir.org) software.
by John A. Magliacane <kd2bd@amsat.org> (08-Apr-2002):
