@@ -1832,3 +1832,62 @@ Added -c option to vwrays to repeat pixels for rtcontr
 Reworked rtcontrib program and renamed to rcontrib.  New version runs much
 faster, especially on multiprocessor systems, and doesn't require as much
 memory.  No longer calls rtrace; instead does all the work itself.
+
+Added -d option to genskyvec to produce direct-only (sun no sky) vector.
+
+Added Ashikhmin-Shirley anisotropic BRDF model (ashik2) with help
+from Nicolas Boneel.
+
+Added Ruby rewrite of objview.csh by Rob Guglielmetti.
+
+Fixed bug in reciprocity for tensor tree BTDF representations.  Thanks
+to Andy McNeil for identifying the problem.
+
+Added MNAME and ZNAME variables to ranimove for debugging & testing.
+
+Created pmblur2 command to take motion and depth buffers from ranimove
+to compute a better motion blur.
+
+****** COMPATIBILITY CHANGE ********
+Changed BSDF routines to use updated/corrected XML specification and
+removed depracated BSDF support from mkillum.
+
+Fixed behavior of i/o flushing in rcontrib with -c > 1 (averaging).  Thanks
+to Lars Grobe for help identifying this problem.
+
+Fixed bug in depth-of-field blur where view distance was measured from
+fore clipping plane rather than viewpoint.  Thanks to Peter A-B for
+pointing this out.
+
+Added options to dctimestep to allow multiple time steps (-n)
+and multiple output pictures or sensor files (-o).  Also added -i
+option to specify float (-if) or double (-id) input for sky matrix.
+
+Created gendaymtx program to compute annual sky patch matrix based
+on Ian Ashdown's implementation of Perez all-weather sky model.
+Output can be sent directly to dctimestep in ASCII or binary stream.
+
+Replaced existing gendaylit.c with improved version from Wendelin Sprenger
+and Jan Wienold of ISE.
+
+Improved accuracy of ambient calculation for large -ad settings.  Thanks
+to Lars Grobe for noticing the problem.
+
+Added -r option to gendaymtx to rotate the sky the specified number of
+degrees about the zenith as suggested by A. McNeil.
+
+Axel Jacobs added -pal eco color map that does a blue-red-yellow scale.
+
+Created bsdf2klems tool to convert from various BSDF representations to
+Klems basis matrix in XML file.
+
+Fixed problem with inappropriate reciprocity enforcement on tensor
+tree reduction in genBSDF.  (Thanks to A.McNeil for discovering issue.)
+
+Fixed bug in isotropic tensor tree sampling for impinging rays
+exactly normal to surface.  Thanks to Peter Apian-Bennewitz for
+discovering and pointing out the error.
+
+Fixed double-counting bug in mirror material with alternate type.
+Thanks to David Geisler-Moroder for spotting the problem and helping
+to fix it.
