 McNeil's 5-phase annual simulation method.
 
 Added epw2wea conversion program by Christoph Reinhart.
+
+Implemented Perlin's improved noise function with help from Rahul Narain.
+This will change the appearance of renderings using this function.
+
+Added "origin" command to rvu as requested by John Mardaljevic
+to place view origin at selected point in scene.
+
+Switch to Perl versions of objview and objpict written by Axel Jacobs.
+
+Improved rendering speed of scenes with aliases by not entering new
+modifiers into table if they are the same as the previously defined
+modifier for that name.
+
+Made it so icalc and rcalc search RAYPATH directories for *.cal files
+given on command line.  This simplifies script writing and makes these
+utilities consistent with other tools in Radiance.
+
+Added triangulation routine to handle convex polygons in obj2mesh.
+
+****** COMPATIBILITY CHANGE ********
+Made backface visibility apply to all material types, including
+transparent and translucent materials (except dielectric and interface).
+This makes the option useful in cases where adjacent trans surfaces
+are placed next to each other by a modeler that only understands
+volumetric objects.
+
+Changed dctimestep so that output matrices (-n > 1) are preceded by a
+header, and added support for float and double output formats with -o[fd].
+
+Introduced eplus_adduvf program to compute user view factors for EnergyPlus.
+
+Changed image-plane sampling in rpict to use Hilbert curve, which gives
+less of a brushed/striped appearance to output pixels with -u- (default).
+
+Added ltview and ltpict Perl scripts contributed by Axel Jacobs, inspired
+by Rob Guglielmetti.
+
+Added header variables for NROWS, NCOLS and NCOMP to help standardize
+matrix files.  This functionality has been incorporated into
+rcollate, gendaymtx, and dctimestep.
