| 1668 |  | ===================== | 
| 1669 |  | Version 4.0 | 
| 1670 | + |  | 
| 1671 | + | Added -n option to rvu to provide parallel rendering. | 
| 1672 | + |  | 
| 1673 | + | ****** COMPATIBILITY CHANGE ******** | 
| 1674 | + | Changed ".pic" extension to ".hdr" in all sources and documentation | 
| 1675 | + | to improve interoperability with other software, since this has become | 
| 1676 | + | the de facto extension for Radiance RGBE and XYZE pictures.  Since file | 
| 1677 | + | extensions were never more than a convention in Radiance, this does not | 
| 1678 | + | affect operation, but may require the update of scripts, etc. written | 
| 1679 | + | by others that assume the ".pic" suffix for Radiance output. |
