 Added rsensor program to compute sensor signal for daylighting controls.
 Funding for this component was provided by the Architectural Energy
 Corporation in Boulder, CO, and directed by Zack Rogers.

+Added "planisphere" (stereographic) fisheye view type for traditional
+daylighting analysis.  Feature requested & explained by Axel Jacobs.
+
+Modified -c option to rtcontrib so it can take a number of input
+rays to average over, rather than only produce a single accumulated
+record (which can now be done with -c 0).

+=====================
+Version 4.0
+
+Added -n option to rvu to provide parallel rendering.
+
+****** COMPATIBILITY CHANGE ********
+Changed ".pic" extension to ".hdr" in all sources and documentation
+to improve interoperability with other software, since this has become
+the de facto extension for Radiance RGBE and XYZE pictures.  Since file
+extensions were never more than a convention in Radiance, this does not
+affect operation, but may require the update of scripts, etc. written
+by others that assume the ".pic" suffix for Radiance output.
+
+Added -N option to objview to support multiprocessing.
+
+Improved sampling of circular sources (source, sphere, ring types) with
+quite a bit of help from David Geisler-Moroder.
+
+Added "rpict" and "rvu" variables to rad, and made these as well as
+the "oconv", "mkillum" and "pfilt" variables accept an alternate
+command path in each case.  Change suggested by Lars Grobe based
+on similar Radzilla (radz) facility by Carsten Bauer.
+
+Fixed rad -v N specification to use actual view name if one.
+
+Fixed error in mkillum calculation where it neglected indirect
+source contributions from BTDF illum's.
+
+Added GMT and LATLONG header lines for Greenwich Mean Time and
+degrees North Latitude / East Longitude.
+
+Added gendaylit to distribution (finally).
+
+Added ability in vwright(1) to get view from command line arguments.
+
+Created genklemsamp(1) utility to generate samples suitable for
+BSDF-based annual calculations.  This is the first Perl script to
+be added to Radiance.  Hopefully, others will follow.
+
+Added klems_int.cal file to compute Klems bins for windows.
+
+Created gentregvec utility to sample a particular sky and
+evaluate average radiance over the standard Tregenza sky patches.
