 Switched default options in rtrace to use Russian roulette.  (Rpict and rvu
 still use biased ray termination.)
+
+Added rtcontrib -r option to recover partial output.
+
+Added -u rendering option for pure Monte Carlo sampling.
+(Got rid of -DMC compile option, which this makes superfluous.)
+
+Changed -t option of rlam to accept strings as well as single characters.
+
+Fixed bug in rcalc with -l option where it would sometimes go into an
+infinite loop.
+
+Fixed truly ancient bug in bounding box computation for cones, which
+could (and did) cause missing segments.
+
+Added -z option to normtiff to output LZW-compressed files.
+
+Last change to total causes it to produce results when it sees an empty
+line on the input.  This was not intentional, but I decided I like this
+behavior so I documented it rather than changing it.

+=====================
+Version 3.8
+
+Fixed Russian roulette ray termination, which was doing the opposite of
+what it should have been doing, resulting in overestimated values below
+minimum ray sampling weight (serious).
+
+Changed mksource to use 98th percentile (rather than 99th) for threshold.
+
+(Above changes included in 3.7.1 patch release.)
+
+Eliminated writing of EXPOSURE= line in ra_tiff -r when source TIFF
+does not have STONITS set.
+
+Fixed bug in ambient calculation that caused black values for multiple
+bounces in some scenes.  Thanks to Mark Stock for creating and sharing
+the sophisticated test scene that demonstrated this problem.
+
+Fixed bug in antimatter using Russian Roulette sampling.
+
+(Above changes included in 3.7.2 patch release 22 Aug 2005.)
+
+Created fieldcomb script to combine alternate fields in a rendering
+sequence.  (Development generously sponsored by Iebele Abel.)
+
+Added missing preload of mesh objects for more efficient memory use
+during parallel rendering -- this was a serious oversight.
+
+Created ran2tiff program to automate exposure setting of animation
+sequences using a moving histogram in combination with pcond, and
+converting frames to TIFF.
