+Release 1.2.0:
+By John A. Magliacane, <kd2bd@amsat.org> (22-Dec-2006):
+
+* All graph plotting has been enhanced to include distances, azimuths,
+  and in some cases, elevation angles, in numeric form.  Height
+  plots (-h option) now include a contour of the Earth's curvature.
+  A new -H option was added that behaves the same as -h, except its
+  display of heights is normalized to the heights of the endpoints
+  along the plotted path.  Graphs now default to PNG rather than GIF
+  format to reflect gnuplot's current trend away from .gif output.
+  (.gif is still available if your version of gnuplot supports it.)
+  Postscript output is now generated in enhanced color.
+
+* SPLAT! can now determine and plot Fresnel Zone clearances.  A new
+  -f command-line option permits the Fresnel Zone frequency (in MHz)
+  to be specified, otherwise it can be determined from .lrp files when
+  path-loss calculations are performed.  Antenna height requirements
+  for 60% clearance (0.6 F1) and 100% clearance (F1) of the First
+  Fresnel Zone now appear in Obstruction Reports.  These zones are
+  also displayed graphically in height plots (-h or -H options).
+
+* Support for antenna radiation patterns has been added.  SPLAT! now
+  reads normalized azimuth and elevation antenna field pattern data
+  from separate .az and .el files when Longley-Rice studies are performed.
+  One degree azimuth and one tenth degree elevation pattern resolution
+  is supported along with azimuthal pattern rotation and mechanical
+  vertical beam tilt. 
+
+* A bug in the interpretation of the -n and -N command-line options
+  was fixed.
+
+* Negative geographical coordinates in DMS format are now (hopefully)
+  interpreted and displayed better than before.
+
+* SPLAT! data handling can be changed from imperial units (feet/miles)
+  to metric (meters/kilometers) units using the new -metric switch.
+
+* SPLAT! can now generate topographic maps without plotting
+  line-of-sight or path loss coverage.  These maps are centered
+  approximately on the given tx_site, extend out to a radius
+  provided by the -R switch, and can be populated with county
+  boundaries and city names, just like SPLAT!'s traditional
+  line-of-sight and path loss maps. 
+
+* Support for user-defined terrain files (ground clutter) has been
+  added.
+
+* SPLAT! can now generate .geo Georeference 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.
+
+* SPLAT! can now generate .kml Keyhole Markup Language files that
+  when imported into "Google Map", dramatically illustrate the RF
+  path between transmitter and receiver locations when performing
+  point-to-point analyses.
+
+* Support for exporting Longley-Rice path loss contour studies to
+  external data files has been included.  SPLAT! path loss files can
+  be used for performing coverage or interference studies outside of
+  SPLAT!.  They can also be modified externally (with antenna pattern
+  data, for example) through scripts or small utilities, and imported
+  back into SPLAT! to generate coverage maps based on the revised
+  data without having to re-run any time intensive Longley-Rice path
+  loss calculations.
+
+* The documentation was updated to reflect the new features and
+  functionality of the software.
