+using new rayfifo calls.
+=====================
-<
+Version 4.1
->
+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
+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 (Release date 7/31/2014)
-+
-+
+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.
-+
-+
+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.
-+
-+
+Created rcollate program to resize and transpose matrix data for Andy
-+
+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.
-+
-+
+Created rmtxop utility to operate on multi-component matrices.  This
-+
+facilitates some daylight matrix calculations, and provides a general
-+
+tool for manipulating matrix data.
-+
-+
+****** COMPATIBILITY CHANGE ********
-+
+Introduced new Hessian-based error control in irradiance caching (ambient)
-+
+calculation.  Since the format of the stored ambient values is different,
-+
+the old files will be rejected with an error message and must be removed.
-+
+The programs may be compiled with the -DOLDAMB option if this is a problem.
-+
-+
+Added -p option to rcontrib to set function file parameters on a per-modifier
-+
+basis to simplify bin evaluation.
-+
-+
+Created rfluxmtx program to compute flux transfer matrices from a sender
-+
+surface to one or more receiver surfaces.  (Renamed the file klems_int.cal
-+
+to klems_full.cal in the process.)
-+
-+
+Added "-c" option to getinfo to execute command on data segment.
-+
-+
+=====================
-+
+Version 4.3
-+
-+
+Changed rmtxop so it writes out same type as lesser of inputs unless
-+
+direction otherwise using -f? option.
-+
-+
+Changed order of oconv arguments in rfluxmtx so user can specify input
-+
+octree using -i option at the end instead of (or in addition to) a
-+
+list of scene files.
-+
-+
+Added support for argument expansion to rfluxmtx and bug fixes.
-+
-+
+Fixed bug in indirect hemisphere sampling for some corner cases.
-+
-+
+Added default specular lobe to BSDF interpolation.
