 Modified pcomb so the first view seen in the inputs is written into header.
 
-Wrote rtpict script to run rtrace in parallel mode and simulate rpict with -n option.
+Wrote rtpict script to run rtrace in parallel mode and simulate rpict with
+-n option.
+
+Added ability to move forwards/backwards specified distance in rvu "origin"
+command.  Feature requested by John Mardaljevic, who essentially owns this
+command, now.
+
+Reduced bias in ambient super-sampling method.
+
+Fixed bugs associated with zero transmission in chromatic tensor trees.
+Thanks to Lars Grobe for pointing out issues.
+
+Added RAYPATH searching for -f options to genrev, gensurf, genworm,
+bsdf2klems, bsdf2ttree, and pcomb.  This makes behavior consistent
+with rcalc, calc, and rendering tools.
+
+Worked with Randolph Fritz to fix some issues with ies2rad and newer
+IESNA63 standards.
+
+Resurrected original bsdf2rad test program, renaming it bsdf2rado. Still an
+optional build in src/cv/.
+
+Fixed bug in rcontrib with virtual sources, where pretest was adding
+to modifier accumulation buffers.  Reported by Mostapha.
+
+Added an "aBSDF" material type that explicitly checks for peak extraction.
+Its arguments are the same as the original "BSDF" type, but without the
+thickness parameter, as proxy geometry is not supported by this new type.
+The old "BSDF" type no longer does peak extraction under any circumstances,
+since this behavior is superfluous for proxied geometry.
+
+Added -r option to bsdf2rad (and bsdfview) to fix BSDF min and max range
+for comparing BSDFs.
+
+Fixed issue with pfilt -m option and uneven image size changes pointed
+out by Rob Shakespeare.
+
+Updates to evalglare and gendaylit from Jan Wienold, including new
+colored sky option.
+
+=========================
+Version 5.3
+
+Created radcompare program to compare Radiance tool output to reference outputs
+during unit-testing.
+
+Fixed issue reading very large files (> 2 GBytes) in rcollate.
+
+Made picking function in rvu ignore transparent and void surfaces.
+
+Added -orRxX options to rtrace to enable output of mirrored and unmirrored
+contributions and distances to enable new types of reprojections.  This also
+cleaned up and unified handling of effective ray lengths throughout code.
+
+Bug fixes from Jan Wienold for evalglare.
+
+Changed indexed (numbered) output from dctimestep to start from 0 rather
+than 1, to make it more consistent with expected input naming.
+
+Increased default sampling in bsdf2klems (-n option) to 1024.
+
+Fixed an issue noticed by David G-M that was causing genBSDF to bias
+isotropic tensor tree samples resulting in subsequent failure of
+peak extraction with "aBSDF" type.
+
+Introduced max() and min() functions to .cal library.
+
+Added random incident patch sampling to bsdf2klems to improve accuracy
+with scattering interpolation representation input (e.g., from
+pabopto2bsdf).  The other input types already sampled incident patch area.
