 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.
+
+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.
