# 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.

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 1924 | Line 1924 | volumetric objects.
1924  
1925   Changed dctimestep so that output matrices (-n > 1) are preceded by a
1926   header, and added support for float and double output formats with -o[fd].
1927 +
1928 + Introduced eplus_adduvf program to compute user view factors for EnergyPlus.
1929 +
1930 + Changed image-plane sampling in rpict to use Hilbert curve, which gives
1931 + less of a brushed/striped appearance to output pixels with -u- (default).
1932 +
1933 + Added ltview and ltpict Perl scripts contributed by Axel Jacobs, inspired
1934 + by Rob Guglielmetti.
1935 +
1936 + Added header variables for NROWS, NCOLS and NCOMP to help standardize
1937 + matrix files.  This functionality has been incorporated into
1938 + rcollate, gendaymtx, and dctimestep.
1939 +
1940 + Created rmtxop utility to operate on multi-component matrices.  This
1941 + facilitates some daylight matrix calculations, and provides a general
1942 + tool for manipulating matrix data.
1943 +
1944 + ****** COMPATIBILITY CHANGE ********
1945 + Introduced new Hessian-based error control in irradiance caching (ambient)
1946 + calculation.  Since the format of the stored ambient values is different,
1947 + the old files will be rejected with an error message and must be removed.
1948 + The programs may be compiled with the -DOLDAMB option if this is a problem.
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.
