 This required a little reprogramming in for couple
 of recursive routines using sets to avoid overrunning
 the stack limit.
+
+==============================
+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 and allows aliases
+as well.
+
+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.
+
+Changed local coordinate index from 32-bits to 16-bits, which requires
+that Radiance mesh files be recompiled.  (Later decided against this
+change, as it caused problems with some models.)
+
+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
+0 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
+
+Improved -f option of normpat, which caused odd color changes before.
+
+Created pgblur script which does fast Gaussian blur of image without changing
+its dimensions.  This is very useful in certain types of image processing
+calculations, such as finding or removing low frequencies.
+
+****** COMPATIBILITY CHANGE ********
+Changed little-used objpict script so that it takes scene files rather than
+rpict options on the command line, and puts everything into the right
+coordinate position automatically rather than requiring the user to do it.
+
+Added -I option to replmarks for mesh instancing.
+
+Made similar change for virtual sources to allow modifiers and aliases
+on the mirror and prism types to work properly.
+
+Rob Guglielmetti dded -lw and -lh options to falsecolor to control the
+legend dimensions.  Made it so -lw 0 and/or -lh 0 turns legend off.
+
+Made it so pcompos will read everything from a stream even if it doesn't
+need it, so input commands will not receive a hangup signal.
+
+Wrote ra_bmp program to convert to and from Windows BMP files (finally).
+It's the most horrible image format I've ever seen, and I've seen a lot.
+
+Increased -aa default value for all renderers (and also -ad and -as in
+rview) at Schorsch's suggestion.  I think this undid my earlier decrease
+of -aa last time, which I guess was ill-considered.
