 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.
+
+Added gendaymtx -A option to compute average sky over all the input
+time steps.
+
+Added ability to output color image from rtrace with any of -ovrx options.
+
+Changed rlam behavior so -iaN reads N lines from a stream rather than N
+characters.  This seems more useful, since -ibN is somewhat redundant with
+the old behavior.
+
+Created rsplit program as compliment to rlam and to handle more complex
+rtrace output into separate files or streams.
+
+Improved getinfo so that it can also hop over resolution string with -c
+and header elide mode.
