+Version 3.5 (Released 3/21/03)
+Fixed bug in replmarks pointed out by Georg Mischler, which caused

+This required a little reprogramming in for couple

-+
-+
+==============================
-+
+Version 3.6
-+
-+
+Modified 4-byte RGBE encoding routine to avoid problems
-+
+when one or two primary values is negative and the other(s)
-+
+positive.  This used to generate some strange color values.
-+
-+
+Added -oc option to rtrace to output local (u,v) coordinates.
-+
-+
+Fixed bugs in local uv and j unit vector variables in src/rt/func.c.
-+
-+
+Added warning message to OpenGL rendering routines about new
-+
+mesh primitive, which we cannot currently render.
-+
-+
+Added -if, -id, -of, and -od options to rcalc to provide for
-+
+binary float and double i/o.
-+
-+
+****************** COMPATIBILITY CHANGE ***********************
-+
+Changed holodeck format to used off_t instead of long for beam
-+
+positions, which allows holodecks to grow to system file size limit.
-+
-+
+Fixed wrapping long in source hit test code, which would cause
-+
+odd horizontal lines in some very long renderings.
-+
-+
+Added -f and -w options to ra_tiff to create IEEE float and 16-bit/primary
-+
+TIFF output, respectively.  These formats are also understood on reverse
-+
+conversion.  (16-bit/primary has been understood for some time, but not
-+
+IEEE float.)
-+
-+
+Added -N option to rad to start multiple rendering processes in
-+
+parallel.
-+
-+
+Fixed bug where mesh instances were not being freed, so subsequent calls
-+
+in programs like ranimate would refer to bogus data.
-+
-+
+Added support in normtiff for floating-point and 16-bit/sample TIFF input
-+
+files.
-+
-+
+Changed marksources() routine (src/rt/source.c) to check all
-+
+primitives in the modifier chain for emitting types, not only
-+
+the first.  This permits sources to be described with intervening
-+
+modifiers before the light/illum/glow primitive.
-+
-+
+Fixed bug in xform where it was neglecting to add transform arguments
-+
+to new mesh primitive.
-+
-+
+Added -dF and -dD options to pvalue for byte-swapped floats and
-+
+doubles, respectively.
-+
-+
+Changed meta2tga to output correct colors.
-+
-+
+****** COMPATIBILITY CHANGE ********
-+
+Changed local coordinate index from 32-bits to 16-bits, which requires
-+
+that Radiance mesh files be recompiled.
-+
-+
+Changed integer tone-mapping routines to better deal with images
-+
+containing large, constant regions.
-+
-+
+Improved interaction with rholo -o ogl driver under OS X, which was
-+
+returning bad values from the depth buffer.
-+
-+
+Minor bug fix in ranimove where it was restarting processes when it
-+
+didn't need to.
-+
-+
+Increased accuracy of default ambient parameters in rpict, rview, and
-+
+rtrace.  In rad program, doubled -ar value, -ad value, and -as value,
-+
+and decreased -aa value a bit.  Also adjusted -lr upwards and -lw
-+
+downwards.  I should have done these things long ago, as processors
-+
+have been getting faster and faster over the years.
-+
-+
+Fixed bug discovered by Marcus Jacobs where oconv was dumping core
-+
+when it was given too many modifiers.
-+
-+
+Fixed problem with rpict where it was drawing illum sources badly
-+
+even when they weren't all that small in the view.
-+
-+
+Added in(i) function to rcalc for more flexible channel evaluation.
-+
-+
+Replaced all calls to vfork() with regular fork() calls.
-+
-+
+Fixed bug in glarendx for dgr calculation with sources behind view.
-+
-+
+Added -p option to histo to print percentages/percentiles r.t. counts.
-+
-+
+Added a source occluder cache to accelerate shadow testing.  This
-+
+can save up to 50% of the calculation time in scenes with many
-+
+light sources, especially ones containing large occluders.  This
-+
+optimization may be tuned or switched off with the -DSHADCACHE=N
-+
+compile switch, where N is the resolution of the shadow cache, or
-+
+to disable it.  Since this is purely a time vs. memory trade-off,
-+
+I decided not to make it a new command-line option.  (We already
-+
+have plenty.)
-+
-+
+****** COMPATIBILITY CHANGE ********
-+
+Changed the following command names to avoid conflicts:
-+
+        rview -> rvu (with symbolic link back to rview)
-+
+        calc -> icalc
-+
+        lam -> rlam
-+
+        gencat -> gencatenary
