| 1807 |  | driver for rvu, which is built in the new subdirectory src/qtrvu. |

| 1809 |  | ===================== | 
| 1810 | < | Version 4.2 |

| 1812 |  | Axel Jacobs added -cp and -palettes options to falsecolor. | 
| 1813 |  |  | 
| 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. |
