 Added "-c" option to getinfo to execute command on data segment.
 
 =====================
-Version 4.3
+Version 5.0
 
 Changed rmtxop so it writes out same type as lesser of inputs unless
-direction otherwise using -f? option.
+directed 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.
+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.
+
+Set minimum number of shadow checks before direct optimization (4).
+
+(Above changes included in 4.2.1 patch release.)
+
+****** COMPATIBILITY CHANGE ********
+Made header input and output the default behavior for dctimestep and
+genskyvec.
+
+****** COMPATIBILITY CHANGE ********
+Changed pabopto2bsdf default behavior to add 90-degree rotation
+to bring pgII's definition of "up" in line with Klems axis
+conventions.  Introduced a new header variable "upphi" to
+control this added rotation.  Using "#upphi 90" in each
+BSDF input file gets back the original behavior, where it
+assumes that the up direction is 90-degrees from the X-axis.
+The default value of 0 corresponds to PAB's definition of
+the X-axis as being "up".
+
+Fixed bug in rsensor related to having many rows (altitude) and
+few columns (azimuth) in sensitivity file.
+
+Fixed floating point round-off error in new Hessian calculation
+for some sytems (Windows, primarily).
+
+Fixed bug in tensor tree BSDF code that caused bus error on
+some systems, and may have been source of other errors as well.
+
+(Above changes included in 4.2.2 patch release.)
+
+Improved ambient extrapolation to avoid zero values.  Actual
+threshold set to 5% of recorded value.
+
+Changed anisotropic Gaussian and Ashikhmin models so that
+illegal orientation vectors are dealt with more gracefully.
+
+Created wrapBSDF tool and incorporated into genBSDF along
+with new rfluxmtx computation.
+
+Initial check-in of Roland Schregle's photon map integration.
+New 5.0a version designation as suggested by Andy McNeil.
+
+Added left-hand coordinate sytems to rfluxmtx to correct
+problems with coordinate axis orientations pointed out by
+David Geisler-Moroder.
+
+Added color output to genBSDF (+C option) and support for
+color rendering of Klems and tensor tree data.
+
+Fixed another bug in rsensor that caused rays to be generated
+on opposite side of hemisphere even where sensitivity was zero.
+
+Fixed bug discovered by Jacob Jonsson in Klems BSDF
+interpolator that caused it to over-predict normal
+transmittance and reflectance.
+
+Added ability to read input from commands in dctimestep
+and rmtxop.
+
+Added photon map support to rad.  Fixed some double-counting
+issues in photon-mapping spotted by David Geisler-Moroder.
+
+Added photon map support to trad.
+
+Fixed bug in antimatter source testing when antimatter
+definition follows potential obstructor in input.
+
+Fixed issue with missing character type identifier at head
+of genBSDF XML output.
+
+Prompted by Roland S., added option to have pcompos -a order
+rows from top rather than bottom of image.
+
+Changed dctimestep to accept matrix as well as BTDF input
+in the VTDs invocation mode.  This permits the output of
+rmtxop to be used in a pinch when combining multiple BTDF
+layers, although interreflection between layers is not
+accounted for properly as it is in the WINDOW program.
+
+Added Jan Wienold et al.'s evalglare to distribution.
+
+Hopeful fix to deadlock issue under Mac OS X 10.10.x (Yosemite).
