 Added new "turbo" palette to falsecolor (thanks to Taoning).
 
 Nathaniel Jones created the "dcglare" program for annual glare
 simulations when the sun and sky are visible through the window.

+
+Added support for loading RGBE images into matrices in dctimestep.
+
+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
+between whitespace.
+
+Added ability of vwrays, pinterp, and pmblur2 to read encoded depth files.
+
+Added -o RxCxR1xC1 facility to perform blocking in rcollate.
+
+Made it so number of segments in genworm, genrev, and gensurf can be
+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.  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.
+
+Fix to glarendx issues with dgi calculation.
+
+Made it so rmtxop and dctimestep undo any exposure applied to Radiance
+pictures they may load.
+
+Added robjutil utility to manipulate Wavefront .OBJ files.
+
+Fixed a crash related to rtrace -om or -oM with mesh instances containing
+materials.
+
+Improved rtrace flushing function to handle any value for -x without
+deadlock on controlling process.
+
+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.
