@@ -1731,3 +1731,55 @@ it was in version 3.5, following recommendation of Dav
 who pointed out that the revised BTDF increased too much at grazing.
 
 Changed rad behavior with -N >1 on single view to call rpiece.
+
+Updated SCons build system for MINGW compilation, thanks to Christian
+Kohler.
+
+Added -u option to rlam for unbuffered output.
+
+Modified dctimestep to accept sky vector and daylight coefficient matrix
+or list of images to sum together, as suggested by Andy McNeil.
+
+Created genBSDF script to generate BSDF in Windows XML format.
+
+Modified mkillum to accept detailed geometry from BSDF XML files.
+
+Altered obj2rad to ignore zero normals (thanks to Jack de Valpine for
+suggestions and help).
+
+Fixed bug in genklemsamp that caused non-uniform sampling over surfaces.
+
+Fixed bugs in rhoptimize and rhcopy for 64-bit compilation.
+
+Made a change to avoid problem using gcc --fast-math compile option.
+
+****** COMPATIBILITY CHANGE ********
+Changed behavior of rtrace and rtcontrib so that every scanline is
+not flushed when both -x and -y are set.  This avoids flush delays
+in rtcontrib for large numbers of output files and delays while
+rendering images using rtrace with the -n option.
+
+Added ability for rsensor to output ray origins and directions
+rather than actually loading octree and computing sensor value.
+
+Fixed old bug in obj2rad where it would stop processing and
+report a syntax error if the "void" type is used in the map file.
+
+Updated reflection model according to EGSR 2010 paper by David
+Geisler-Moroder and Arne Duer.
+
+Replaced C-shell version of falsecolor with Perl script written
+by Axel Jacobs.
+
+****** COMPATIBILITY CHANGE ********
+Changed -sj (specular jitter) option to something called specular
+sampling (-ss), which if set less than 1 has the same behavior as
+the old -sj, but when set greater than 1, spawns multiple ray
+samples from semi-specular surfaces.
+
+Fixed bug noticed by Randolph Fritz that caused ambient sync errors.
+
+Fixed bug in findglare for reading picture files under Windows.
+
+Added options to pvalue to note other color spaces on reverse conversion.
+Thanks to Erich Philips for the feature request.
