 Added tilde ('~') output option as part of the -o* specification of
 rtrace.  This permits ray trees to be parsed more easily in binary
 output mode, as needed by rtcontrib.
+
+Implemented Russian roulette ray termination with -lr <= 0.
+Made -lr -10 the default in rtcontrib.
+
+Made rtcontrib -f option search RAYPATH directories.
+
+Made it so -o option of rtcontrib can pipe -o output to a command.
+
+Added -if and -of options to total for binary i/o (following rcalc mold).
+
+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.
