# Line 2444 | Line 2444 | produces normal smoothing unless normals are removed w
2444  
2445   Added exposure preservation to pcompos when possible (i.e., when
2446   there is only one input or inputs agree on exposure).
2447 +
2448 + Added -DSHARP_RGB compile-time option to use sharp RGB color space
2449 + rather than historic default.  This can make for more accurate color
2450 + calculations, but requires that materials be recalibrated.  The
2451 + PRIMARIES= line is also produced on output from rpict or rvu with
2452 + the correct set of primaries based on how the system was compiled.
2453 +
2454 + Added automatic flushing to the output of total, except when the -r
2455 + (running subtotals) option is used.
2456 +
2457 + Improved behavior of little-used -aw option, so that it avoids sea-level
2458 + rise caused by adding its own estimate back into the ambient level remainder.
2459 + It ended up being simple enough to derate the final average by the factor
2460 + corresponding to average surface absorpition, thus removing the average
2461 + from the final bounce estimate.
