+colored sky option.
+=========================
-<
+Version 5.3
->
+Version 5.3 (Released September 1, 2020)
+Created radcompare program to compare Radiance tool output to reference outputs
+during unit-testing.
+Added new depth, normal, and ID file types to radcompare.
+Added BigEndian= header line for automatic byte-swapping in rmtxop
-<
+and radcompare.  Doesn't work quite as automatically as it should
-<
+for pvalue -r, currently.
->
+and radcompare.
+Added new "turbo" palette to falsecolor (thanks to Taoning).
+Added -y option to gensky and gendaylit to support more accurate Michalsky
+solar position calculation.
-<
+Changed rsplit so specifying a space as the separator parses words
->
+Changed rsplit, so specifying a space as the separator parses words
+between whitespace.
+Added ability of vwrays, pinterp, and pmblur2 to read encoded depth files.
+given as expressions of previously defined variables, etc.
+Added -D and -n option to gendaymtx to output sun description and skip
-<
+matrix output on request.
->
+matrix output on request.  A -M option was also added to output solar
->
+modifiers for rcontrib.  Support also added for leap days in WEA input.
->
+Enhancements sponsored by Ladybug Tools.
+Updated eplus_uvf to work with IDF version 9.x, checking version number.
+Made it so rmtxop and dctimestep undo any exposure applied to Radiance
+pictures they may load.
-<
+Added objutil utility to manipulate Wavefront .OBJ files.
->
+Added robjutil utility to manipulate Wavefront .OBJ files.
+Fixed a crash related to rtrace -om or -oM with mesh instances containing
+materials.
+Eliminated unnecessary start-up procedures for rtrace when only ray-casting
+is needed (i.e., no tracing or value output).
-+
-+
+Improved isotropic sampling method in bsdf2ttree using "zipper" approach
-+
+applied in genBSDF.
-+
-+
+Added limit to memory used by high-resolution tensor tree BSDFs for
-+
+cumulative cache during MC sampling (rendering).  Limit set to 250MBytes
-+
+per BSDF for standard architectures.
-+
-+
+Added -n and -s options to bsdf2ttree to provide some user control
-+
+over super-sampling.
-+
-+
+Improved surface normal codec used by ambient file to store orthonormal
-+
+directions exactly.
-+
-+
+Improved peak extraction method, which was undervaluing transmission
-+
+in many cases.
-+
-+
+New version of evalglare from Jan Wienold.
-+
-+
+Added -u option to gendaymtx to elide data columns (time steps) when
-+
+the sun is not visible above the horizon.
-+
-+
+=========================
-+
+Version 5.4
-+
-+
+Added rcollate -c option to force operation to continue even if it
-+
+seems unnecessary.  Made tool more robust.
-+
-+
+Added -t option to rcontrib (and rfluxmtx) to report progress after the
-+
+given number of seconds.
-+
-+
+Added "test" target to makeall to run unit tests.
-+
-+
+Modified bsdf2ttree to allow different parameters per input SIR file.
-+
-+
+Fixed issues with very large matrix files (> 2GB) in dctimestep, rmtxop,
-+
+and rcollate.
-+
-+
+Added -rf and -rb options to rmtxop to load front or back reflectance
-+
+matrix data from XML file rather than transmission.  (Lars Grobe suggested.)
-+
-+
+Improved behavior for coincident surfaces with different materials.
-+
+Rather than returning one surface or the other based on floating-point
-+
+vagaries, opaque materials are now preferred over transparent ones.
-+
+If the materials are both transparent or both opaque, then whichever
-+
+surface appeared later in the scene description will be selected.
-+
+This came of a request for consistent behavior with legal CAD output
-+
+from Peter Apian-Bennewitz.
-+
-+
+Added explicit tests for on-edge intersections with polygons.  This should
-+
+eliminate stray rays and tiny light leaks that often appear even in
-+
+well-constructed geometry.
-+
-+
+Added "-s up" option to pabopto2bsdf to allow for 180 degree symmetry,
-+
+meaning that data repeats after 180 degree rotation (as distinguished
-+
+from "-s bilateral" whose data is mirrored about a vertical plane).
-+
+Thanks to Helen Rose Wilson for the suggestion and informing me that
-+
+such a thing exists.
-+
-+
+Removed upper limit on number of modifiers in rcontrib.
-+
-+
+Put cap on maximum ambient gradient to avoid over-extrapolation of
-+
+poorly computed irradiance cache values.
-+
-+
+Added robjutil +T option to triangulate all faces in .OBJ description.
-+
-+
+Altered BSDF library to have both front and back diffuse transmittance
-+
+values, which can be different.  This was necessary to avoid issues
-+
+caused by measurement and modeling discrepancies.
-+
-+
+Added pabopto2bsdf -g option to cull near-grazing scattering to avoid
-+
+issues with noise and negative values.
-+
-+
+Increased default dynamic range from 32 to 100 in pcond and normtiff.
-+
-+
+Added -o and -n options to genbox to create .OBJ output and segment
-+
+edges and corners for transparent materials.  Also added -s option
-+
+to control smoothing for .OBJ and Radiance with segmented rounding.
-+
-+
+Made it so robjutil with the +r option for Radiance output now
-+
+produces normal smoothing unless normals are removed with -n.
-+
-+
+Added exposure preservation to pcompos when possible (i.e., when
-+
+there is only one input or inputs agree on exposure).
-+
-+
+Added -DSHARP_RGB compile-time option to use sharp RGB color space
-+
+rather than historic default.  This can make for more accurate color
-+
+calculations, but requires that materials be recalibrated.  The
-+
+PRIMARIES= line is also produced on output from rpict or rvu with
-+
+the correct set of primaries based on how the system was compiled.
-+
-+
+Added automatic flushing to the output of total, except when the -r
-+
+(running subtotals) option is used.
-+
-+
+Improved behavior of little-used -aw option, so that it avoids sea-level
-+
+rise caused by adding its own estimate back into the ambient level remainder.
-+
+It ended up being simple enough to derate the final average by the factor
-+
+corresponding to average surface absorpition, thus removing the average
-+
+from the final bounce estimate.
-+
-+
+Introduced ies2rad upgrades by Randolph Fritz.  Randolph says it
-+
+fixes the following problems:
-+
-+
+. Generates correct Radiance geometry for spheres in 1995, 2002,
-+
+        and 2019 IES files.
-+
-+
+. Generates correct Radiance geometry for vertical cylinders that
-+
+        are taller than they are wide.
-+
-+
+. Ignores the file source ("File Generation Type") field in the
-+
+version of the file, which would otherwise be incorrectly used
-+
+        as an output multiplier.
-+
-+
+    It also offers the following enhancements:
-+
-+
+. Shape information is included in the .rad file comments.
-+
-+
+. 1995, 2002, and 2019-version luminous opening geometry is
-+
+        accounted for.
-+
-+
+. The 2002 and 2019 IES file versions are recognized and
-+
+        processed appropriately.
-+
-+
+. I have made an attempt to do something intelligent with less
-+
+        common "luminous opening" shapes in the 1995, 2002, and 2019 versions
-+
+        of the standard, though I have not implemented any support for new
-+
+        geometry; approximations are substituted and warning messages issued.
-+
+        Unfortunately, this code is not tested, since I don't have any IES
-+
+        files that use these shapes.
-+
-+
+Added support for depth-of-field blurring in vwrays using -pd option.
-+
+Also, made -c count work with vwrays -i, producing multiple samples
-+
+per indicated pixel position.  At the same time, support for the -pd
-+
+option was added to rtpict, which calls on vwrays for its samples.
-+
-+
+Fixed issue with BSDFs that didn't obey reciprocity, where direct
-+
+sampling wasn't following exactly with indirect sampling.  This was
-+
+discovered and reported by Jon Sargent.
-+
-+
+Created checkBSDF tool to test XML BSDF reciprocity and perform similar
-+
+sanity checks.
-+
-+
+Added -O option to pvalue and pextrem to report watts/sr/m^2 even if
-+
+picture is XYZE.
