 Bug fixes in rsensor thanks to help from David Geisler-Moroder.
 
 Added variable-resolution BSDF support in renderers and genBSDF.
+
+Created pkgBSDF program to extract BSDF geometry and put it
+together with surface description suitable for inclusion in
+a Radiance scene.
+
+Muted warning for "no light sources found" when there is at least
+one glow object and interreflections are on (-ab > 0).
+
+Fixed long-standing bug that caused underestimation of reflection
+when specular component was below -st threshold in non-metals.
+
+Checked in cross-platform cmake build system created by Bill Hoffman
+of KitWare and sponsored by NREL.  This includes a qt-based
+driver for rvu, which is built in the new subdirectory src/qtrvu.

+=====================
+Version 4.2
+
+Axel Jacobs added -cp and -palettes options to falsecolor.
+
+Fixed bug in matrix output of genBSDF introduced shortly before 4.1 release.
+
+Made rvu more responsive in multi-processing mode when changing parameters.
+Explicit "new" command not needed to show changes, because it goes back
+to "immediate mode" once something is changed.  Processing will be slow
+but response time quick until next "new" command.
+
+Fixed major bug in transmitting proxy material sampling.
+
+Patched cmake build tools (changes by Zack Galbreath).
+
+Removed requirement for pflip -h to be given input file (can pipe from stdin).
