 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 lengths 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.
+
+Modified gensky behavior so if time is given with standard time zone
+designation, any -m option is ignored.
+
+Added -n option to mkillum for (shared memory) parallel processing.
+
+Fixed a long-standing bug in parallel processing code that only
+seemed to manifest with the new mkillum -n option, where rtrace
+would deadlock upon termination.  The reason it never showed up
+before is because I always closed processes in the reverse order
+of opening them in other programs.  I went through and found similar
+(potential) bugs in the rview device subprocess code and util/netproc.c.
+
+Corrected the normalization of the Gaussian reflectance model.  This will
+cause an increase in specularity for low-lying light sources.
+Thanks to Don Walters of Boeing and Arne Duer of the Univ. of Innsbruck
+for pointing out this error.  The square root used for the two cosines
+in the denominator of the normalization factor should not be present.
+This was a serious mistake I made in the original model, which went
+undiscovered (at least to my knowledge) for over a decade.  I think
+Bruce Walter of Cornell may have known about it, but I never heard
+the details of his discovery.
+
+Enabled the -p option for primary conversion without tone-mapping
+in ra_bmp.  Also provides for XYZE input conversion to RGB.
+
+Fixed what I consider a bug in pvalue -o when taking XYZE files on input,
+where it was inappropriately undoing the exposure value so that it always
+reported radiance rather than XYZ values with Y in cd/m^2.
+
+Made it so ra_bmp only produces run-length encoded 8-bit output for
+grayscale images that are tone-mapped.  This minimizes circumstances
+under which output scanline order is reversed.
+
+Fixed bug in rcalc where it sometimes wasn't parsing the input format
+correctly.
+
+=====================
+Version 3.7
+
+Fixed bug in source occluder cache which caused consistency error
+for distant sources and mist materials.  (Thanks to Mark Stock for
+finding the problem.)
+
+Fixed serious bug in source drawing routines for rpict, where the edges
+of light sources were appearing through obstructions.  (Thanks to Veronica
+Sundstedt for pointing this out.)
+
+(The above were included in the 3.6.1 patch release.)
+
+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.
