 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.
