 to get back higher precision representation.
+
+Taoning Wang updated genssky and gensdaymtx to provide illuminance
+calibration and accept EPW files directly as input.
+
+Added -e expr and -f file.cal options to all rendering tools, not
+just rcontrib/rxcontrib.  Feature request from Peter A-B.
+
+Fixed slight bias in indirect calculation caused by ambient
+collision detection, pointed out by Jon Sargent.  New code
+keeps track of rejected samples and sells them back to
+later calls to get something closer to a true Poisson
+sampling method.
+
+Altered rvu "origin" command to take shift amounts forward,
+right, and up rather than taking an explicit origin, which
+can be done easily enough with the "view" command.  Peter A-B
+requested (sort of).
+
+Added genglaze tool created by Taoning Wang to generate
+spectral glazing materials based on CGDB data and models.
+
+Fixed bug that caused inf and nan errors with -cw setting
+where longer wavelength was substantially less than limits
+of specified spectra.
+
+Created bsdfpeaks utility to identify and report full-width,
+half-maximum sizes of peaks in SIR and XML inputs.
+
+Changed default super-sampling in bsdf2ttree from 256 to 64,
+since there doesn't seem to be much benefit to the higher
+sampling rate for most BSDFs.
