+parallel.
+Fixed bug where mesh instances were not being freed, so subsequent calls

+in programs like ranimove 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.
->
+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
-+
+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.
-+
-+
+Modified oconv to keep subdividing the octree if there are too many
-+
+objects in a voxel even when the -r resolution limit has been
-+
+reached.  This was not done before due to problems with recursion,
-+
+and still, it will only continue to 256 times the original -r limit.
-+
+If that isn't enough, then there's probably no hope, anyway.
-+
-+
+Added -l option to obj2mesh to search for material files in library
-+
+locations.
-+
-+
+Increased polygon vertex limit to 512 in obj2mesh and obj2rad and added
-+
+warning if this limit is exceeded.
-+
-+
+Added tone-mapping and monitor primary options to ra_bmp.  This gives
-+
+new functionality similar to normtiff and ximage.  It would be nice to
-+
+add this feature to the other ra_* programs as well...  someday.
-+
-+
+Fixed long-standing bug in reported pixel ordering out of certain
-+
+protate commands.
-+
-+
+Added -p option to rcalc for "passive mode" that transmits
-+
+unrecognized input -- useful for substituting data in the
-+
+middle of a stream.
-+
-+
+Fixed a very obscure bug in rpict that caused a dark horizontal
-+
+line in certain cylindrical projections due to improper drawing
-+
+of the sky dome source in rt/srcdraw.c.
-+
-+
+Fixed problems with effective ray lenths computed for dielectric
-+
+and BRTDfunc materials.  This was most evident in breakup of holodeck
-+
+views when VDISTANCE=True.
-+
-+
+Fixed rad so that 'scene' variable may consist only of inline commands.
-+
-+
+Fixed bug introduced in shadow caching routines where sources in the
-+
+middle of spheres were not illuminating properly.  Thanks to Guilio
-+
+Antonutto for spotting this problem.
