 Changed pcomb so -o option elides original exposure values
 from indented source headers.
+
+Added getinfo -r option, which is similar to -a except it will
+replace indicated lines with new ones.
+
+Slight change to vwrays -d option to not spit out "-ld-", and to
+produce "-ld+" without requiring input picture as argument.
+
+Added automatic overture calculation to rtpict with -n > 1 if
+ambient cache is on and file is named.  If straight image output
+is requested, we randomize all samples and avoid cache collisions.
+
+Added cnt -s option to shuffle output.
+
+Fixed issue with divide-by-zero errors in the ambient super-sampling
+routine discovered by Jon Sargent of Solemma.  This affected regions
+that had zero radiance, such as black backgrounds or unlit areas
+with -av 0 0 0, when super-sampling was effectively disabled, causing
+some loss in accuracy of the results.
+
+Updated Klems Half- and Quarter-bases to match angles currently used
+in WINDOW.
+
+Eliminated most aiming failures for triangular light sources, at the
+expense of conservative sampling near the centroid.  Thanks to
+David Geisler-Moroder for his help on this.
+
+Increased maximum set size to 8191 to avoid set overflow errors.
+
+Added source obstruction test to statistics being kept on which
+sources were visible in adaptive shadow testing code.  Previous
+behavior was likely over-estimating source contributions.
+
+Added diffuse components into maximum directional hemispherical
+reported by checkBSDF, so comparing to 100% is easier for each
+component.
+
+Fixed incorrect calculations in iso2klems script, thanks to
+help from Jacob Jonnson.
+
+Updated official copyright and license according to new wording
+provided by Jean Haemmerle at the LBNL Intellectual Property Office.
+Both were copied verbatim from e-mail I received from Taoning Wang
+on 8/20/2022.
+
+Added -features option to rpict, rtrace, and rcontrib to check
+which features are present or look for specific feature support.
+This addition was suggested by Peter Apian-Bennewitz as an easier
+way to determine which version of Radiance is installed and what
+it supports, and is timely as we begin our refactoring of the
+rendering code.  There are no current plans to add this to rvu.
+
+Added falsecolor -odim, -orct, and -c0 options to overlay grid of
+values on image.  This was requested by Rob Shakespeare.
+
+Added -i* and -o* options in rhcopy for reading rays from the
+standard input and writing rays from holodeck to standard output.
+This will hopefully be useful in combining rholo with rcontrib.
