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.
1680 +
1681 + Added -N option to objview to support multiprocessing.
1682 +
1683 + Improved sampling of circular sources (source, sphere, ring types) with
1684 + quite a bit of help from David Geisler-Moroder.
1685 +
1686 + Added "rpict" and "rvu" variables to rad, and made these as well as
1687 + the "oconv", "mkillum" and "pfilt" variables accept an alternate
1688 + command path in each case.  Change suggested by Lars Grobe based
1689 + on similar Radzilla (radz) facility by Carsten Bauer.
1690 +
1691 + Fixed rad -v N specification to use actual view name if one.
1692 +
1693 + Fixed error in mkillum calculation where it neglected indirect
1694 + source contributions from BTDF illum's.
1695 +
1696 + Added GMT and LATLONG header lines for Greenwich Mean Time and
1697 + degrees North Latitude / East Longitude.
1698 +
1699 + Added gendaylit to distribution (finally).
1700 +
1701 + Added ability in vwright(1) to get view from command line arguments.
1702 +
1703 + Created genklemsamp(1) utility to generate samples suitable for
1704 + BSDF-based annual calculations.  This is the first Perl script to
1705 + be added to Radiance.  Hopefully, others will follow.
1706 +
1707 + Added klems_int.cal file to compute Klems bins for windows.
