# Line 1807 | Line 1807 | of KitWare and sponsored by NREL.  This includes a qt-
1807   driver for rvu, which is built in the new subdirectory src/qtrvu.
1808  
1809   =====================
1810 < Version 4.2
1810 > Version 4.2 (Release date 7/31/2014)
1811  
1812   Axel Jacobs added -cp and -palettes options to falsecolor.
1813  
# Line 1949 | Line 1949 | The programs may be compiled with the -DOLDAMB option
1949  
1950   Added -p option to rcontrib to set function file parameters on a per-modifier
1951   basis to simplify bin evaluation.
1952 +
1953 + Created rfluxmtx program to compute flux transfer matrices from a sender
1954 + surface to one or more receiver surfaces.  (Renamed the file klems_int.cal
1955 + to klems_full.cal in the process.)
1956 +
1957 + Added "-c" option to getinfo to execute command on data segment.
1958 +
1959 + =====================
1960 + Version 4.3
1961 +
1962 + Changed rmtxop so it writes out same type as lesser of inputs unless
1963 + direction otherwise using -f? option.
1964 +
1965 + Changed order of oconv arguments in rfluxmtx so user can specify input
1966 + octree using -i option at the end instead of (or in addition to) a
1967 + list of scene files.
1968 +
1969 + Added support for argument expansion to rfluxmtx and bug fixes.
1970 +
1971 + Fixed bug in indirect hemisphere sampling for some corner cases.
1972 +
1973 + Added default specular lobe to BSDF interpolation.
1974 +
1975 + Set minimum number of shadow checks before direct optimization (4).
1976 +
1977 + (Above changes included in 4.2.1 patch release.)
1978 +
1979 + ****** COMPATIBILITY CHANGE ********
1980 + Made header input and output the default behavior for dctimestep and
1981 + genskyvec.
1982 +
1983 + ****** COMPATIBILITY CHANGE ********
1984 + Changed pabopto2bsdf default behavior to add 90-degree rotation
1985 + to bring pgII's definition of "up" in line with Klems axis
1986 + conventions.  Introduced a new header variable "upphi" to
1987 + control this added rotation.  Using "#upphi 90" in each
1988 + BSDF input file gets back the original behavior, where it
1989 + assumes that the up direction is 90-degrees from the X-axis.
1990 + The default value of 0 corresponds to PAB's definition of
1991 + the X-axis as being "up".
