+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.
