 Changed default temporary directory from /usr/tmp, which doesn't exist
 on a lot of systems these days, to /tmp.
+
+Eliminated many unused files and programs from the distribution, including
+the following programs that were being built but no longer used:
+	oki20	- printer driver for OkiMate 20 printer (B&W)
+	oki20c	- printer driver for OkiMate 20 color printer
+	pcwarp	- intended as more general substitute for macbetcal,
+			but never quite worked
+	ra_avs	- convert to & from AVS image format
+	ra_bn	- convert to & from Barneyscann format
+	ra_pr	- convert to & from 8-bit Sun rasterfile format
+	ra_pr24	- convert to & from 24-bit Sun rasterfile format
+	thf2rad	- convert GDS "things file" to Radiance scene format
+If anyone is still wanting any of the above programs, let us know and we'll
+reinstate it.
+
+Fixed bug in pcond's acuity simulation for small view angles (less than
+4 degrees horizontally or vertically).  Thanks to James Lee for figuring
+this out.
+
+Added script to convert to/from ICT's Poskanzer Float Map, which I don't
+care to support officially due to its machine-dependent byte order.
+
+Fixed bug that caused incorrect reporting of non-surface in set when
+mixing meshes and instances.  (Thanks to Jack de Valpine for discovery.)
+
+Fixed innacuracy in calculation of diffuse transmission in the presence
+of pure specular (Fresnel reflection) using "trans" material.  Thanks
+to Christoph Reinhart for pointing out the error.
+
+Made internal change to tone-mapping library to use structure pointer
+rather than stack, making code re-entrant and more up to modern standards.
+
+Added -pd option to handle depth-of-field blur in rpict.  This requires
+that the view directon (-vd option) include focal distance information,
+which is now preserved by the various view file routines, and reported
+by the vwright command.
+
+Added DBLUR variable to ranimate and pmdblur script to handle simultaneous
+motion and depth-of-field blurring.  Thanks to Visarc for funding this work.
+
+Added setting of focus distance in rvu ("focus" command) and rholo
+('f'/"frame" command).
+
+Changed default remote shell in ranimate to "ssh" rather than "rsh",
+which has been abandoned on most Unix systems due to security issues.
+
+Fixed behavior of source primitive using illum with no alternate
+material.  These now become transparent so one can see the sky or
+light-probe background for use in image-based lighting.  Previously,
+the user needed to specify the background glow as the alternate
+material for a distant illum source to behave properly.  (This still
+works.)
+
+Fixed some minor problems and inconsistencies with 16-bit/channel
+TIFF i/o in ra_tiff.
+
+Created mksource program to generate distant sources for improved
+image-based lighting with light probes.
