+Version 4.2 (Release date 7/31/2014)
 
 Axel Jacobs added -cp and -palettes options to falsecolor.
 
@@ -1946,3 +1946,69 @@ Introduced new Hessian-based error control in irradian
 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.
+
+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.
