+the stack limit.
+==============================
-<
+Version 3.6
->
+Version 3.6 (Released 10/21/04)
+Modified 4-byte RGBE encoding routine to avoid problems
+when one or two primary values is negative and the other(s)
+correctly.
+=====================
-<
+Version 3.7
->
+Version 3.7 (Released 7/25/05)
+Fixed bug in source occluder cache which caused consistency error
+for distant sources and mist materials.  (Thanks to Mark Stock for
+behavior so I documented it rather than changing it.
+=====================
-<
+Version 3.8
->
+Version 3.8 (Released 10/17/06)
+Fixed Russian roulette ray termination, which was doing the opposite of
+what it should have been doing, resulting in overestimated values below
+Added -h option to pcompos and pcomb to eliminate verbose headers.
+=====================
-<
+Version 3.9
->
+Version 3.9 (Released 3/30/08)
+Added -spec option to falsecolor to restore original spectral color scale.
+Also added "-s auto" option to automatically set the maximum value.
+record (which can now be done with -c 0).
+=====================
-<
+Version 4.0
->
+Version 4.0 (Released 3/12/10)
+Added -n option to rvu to provide parallel rendering.
+extensions were never more than a convention in Radiance, this does not
+affect operation, but may require the update of scripts, etc. written
+by others that assume the ".pic" suffix for Radiance output.
-+
-+
+Added -N option to objview to support multiprocessing.
-+
-+
+Improved sampling of circular sources (source, sphere, ring types) with
-+
+quite a bit of help from David Geisler-Moroder.
-+
-+
+Added "rpict" and "rvu" variables to rad, and made these as well as
-+
+the "oconv", "mkillum" and "pfilt" variables accept an alternate
-+
+command path in each case.  Change suggested by Lars Grobe based
-+
+on similar Radzilla (radz) facility by Carsten Bauer.
-+
-+
+Fixed rad -v N specification to use actual view name if one.
-+
-+
+Fixed error in mkillum calculation where it neglected indirect
-+
+source contributions from BTDF illum's.
-+
-+
+Added GMT and LATLONG header lines for Greenwich Mean Time and
-+
+degrees North Latitude / East Longitude.
-+
-+
+Added gendaylit to distribution (finally).
-+
-+
+Added ability in vwright(1) to get view from command line arguments.
-+
-+
+Created genklemsamp(1) utility to generate samples suitable for
-+
+BSDF-based annual calculations.  This is the first Perl script to
-+
+be added to Radiance.  Hopefully, others will follow.
-+
-+
+Added klems_int.cal file to compute Klems bins for windows.
-+
-+
+Created genskyvec  utility to sample a particular sky and
-+
+evaluate average radiance over the standard Tregenza sky patches.
-+
-+
+Created dctimestep program to compute a set of sensor values or
-+
+a combined image for a particular time using the daylight
-+
+coefficient method.
-+
-+
+Created src/rt/rayfifo.c for first-in/first-out handling of
-+
+multiprocessing by raypcalls.c.
-+
-+
+Added -n option to rtrace for executing on multiple cores
-+
+using new rayfifo calls.
-+
-+
+=====================
-+
+Version 4.1 (Released 11/04/2011)
-+
-+
+Changed ranimate behavior so remote login under a different user
-+
+doesn't necessarily require the presence of the originating user's
-+
+home directory.
-+
-+
+Changed standard transmission function normalization back to what
-+
+it was in version 3.5, following recommendation of David Geisler-Moroder,
-+
+who pointed out that the revised BTDF increased too much at grazing.
-+
-+
+Changed rad behavior with -N >1 on single view to call rpiece.
-+
-+
+Updated SCons build system for MINGW compilation, thanks to Christian
-+
+Kohler.
-+
-+
+Added -u option to rlam for unbuffered output.
-+
-+
+Modified dctimestep to accept sky vector and daylight coefficient matrix
-+
+or list of images to sum together, as suggested by Andy McNeil.
-+
-+
+Created genBSDF script to generate BSDF in Windows XML format.
-+
-+
+Modified mkillum to accept detailed geometry from BSDF XML files.
-+
-+
+Altered obj2rad to ignore zero normals (thanks to Jack de Valpine for
-+
+suggestions and help).
-+
-+
+Fixed bug in genklemsamp that caused non-uniform sampling over surfaces.
-+
-+
+Fixed bugs in rhoptimize and rhcopy for 64-bit compilation.
-+
-+
+Made a change to avoid problem using gcc --fast-math compile option.
-+
-+
+****** COMPATIBILITY CHANGE ********
-+
+Changed behavior of rtrace and rtcontrib so that every scanline is
-+
+not flushed when both -x and -y are set.  This avoids flush delays
-+
+in rtcontrib for large numbers of output files and delays while
-+
+rendering images using rtrace with the -n option.
-+
-+
+Added ability for rsensor to output ray origins and directions
-+
+rather than actually loading octree and computing sensor value.
-+
-+
+Fixed old bug in obj2rad where it would stop processing and
-+
+report a syntax error if the "void" type is used in the map file.
-+
-+
+Updated reflection model according to EGSR 2010 paper by David
-+
+Geisler-Moroder and Arne Duer.
-+
-+
+Replaced C-shell version of falsecolor with Perl script written
-+
+by Axel Jacobs.
-+
-+
+****** COMPATIBILITY CHANGE ********
-+
+Changed -sj (specular jitter) option to something called specular
-+
+sampling (-ss), which if set less than 1 has the same behavior as
-+
+the old -sj, but when set greater than 1, spawns multiple ray
-+
+samples from semi-specular surfaces.
-+
-+
+Fixed bug noticed by Randolph Fritz that caused ambient sync errors.
-+
-+
+Fixed bug in findglare for reading picture files under Windows.
-+
-+
+Added options to pvalue to note other color spaces on reverse conversion.
-+
+Thanks to Erich Philips for the feature request.
-+
-+
+Added BSDF data-driven material type with full sampling support.
-+
-+
+Added BRDF calculations to genBSDF.
-+
-+
+Bug fixes in rsensor thanks to help from David Geisler-Moroder.
-+
-+
+Added variable-resolution BSDF support in renderers and genBSDF.
-+
-+
+Created pkgBSDF program to extract BSDF geometry and put it
-+
+together with surface description suitable for inclusion in
-+
+a Radiance scene.
-+
-+
+Muted warning for "no light sources found" when there is at least
-+
+one glow object and interreflections are on (-ab > 0).
-+
-+
+Fixed long-standing bug that caused underestimation of reflection
-+
+when specular component was below -st threshold in non-metals.
-+
-+
+Checked in cross-platform cmake build system created by Bill Hoffman
-+
+of KitWare and sponsored by NREL.  This includes a qt-based
-+
+driver for rvu, which is built in the new subdirectory src/qtrvu.
-+
-+
+=====================
-+
+Version 4.2
-+
-+
+Axel Jacobs added -cp and -palettes options to falsecolor.
-+
-+
+Fixed bug in matrix output of genBSDF introduced shortly before 4.1 release.
-+
-+
+Made rvu more responsive in multi-processing mode when changing parameters.
-+
+Explicit "new" command not needed to show changes, because it goes back
-+
+to "immediate mode" once something is changed.  Processing will be slow
-+
+but response time quick until next "new" command.
-+
-+
+Fixed major bug in transmitting proxy material sampling.
-+
-+
+Patched cmake build tools (changes by Zack Galbreath).
-+
-+
+Removed requirement for pflip -h to be given input file (can pipe from stdin).
-+
-+
+Added "Number of processes" slider to trad "Action" pane to control rad -N
-+
+option for rvu and batch rendering.
-+
-+
+Added -c option to vwrays to repeat pixels for rtcontrib.
-+
-+
+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.
