# Line 1382 | Line 1382 | care to support officially due to its machine-dependen
1382   Fixed bug that caused incorrect reporting of non-surface in set when
1383   mixing meshes and instances.  (Thanks to Jack de Valpine for discovery.)
1384  
1385 < Fixed innacuracy in calculation of diffuse transmission in the presence
1385 > Fixed inaccuracy in calculation of diffuse transmission in the presence
1386   of pure specular (Fresnel reflection) using "trans" material.  Thanks
1387   to Christoph Reinhart for pointing out the error.
1388  
# Line 1471 | Line 1471 | still use biased ray termination.)
1471  
1472   Added rtcontrib -r option to recover partial output.
1473  
1474 < Added -R rendering option for pure Monte Carlo sampling.
1475 < (Got rid of -DMC compile option, whicht his makes superfluous.)
1474 > Added -u rendering option for pure Monte Carlo sampling.
1475 > (Got rid of -DMC compile option, which this makes superfluous.)
1476 >
1477 > Changed -t option of rlam to accept strings as well as single characters.
1478 >
1479 > Fixed bug in rcalc with -l option where it would sometimes go into an
1480 > infinite loop.
1481 >
1482 > Fixed truly ancient bug in bounding box computation for cones, which
1483 > could (and did) cause missing segments.
1484 >
1485 > Added -z option to normtiff to output LZW-compressed files.
1486 >
1487 > Last change to total causes it to produce results when it sees an empty
1488 > line on the input.  This was not intentional, but I decided I like this
1489 > behavior so I documented it rather than changing it.

1491 > =====================
1492 > Version 3.8
1493 >
1494 > Fixed Russian roulette ray termination, which was doing the opposite of
1495 > what it should have been doing, resulting in overestimated values below
1496 > minimum ray sampling weight (serious).
1497 >
1498 > Changed mksource to use 98th percentile (rather than 99th) for threshold.
1499 >
1500 > (Above changes included in 3.7.1 patch release.)
1501 >
1502 > Eliminated writing of EXPOSURE= line in ra_tiff -r when source TIFF
1503 > does not have STONITS set.
1504 >
1505 > Fixed bug in ambient calculation that caused black values for multiple
1506 > bounces in some scenes.  Thanks to Mark Stock for creating and sharing
1507 > the sophisticated test scene that demonstrated this problem.
1508 >
1509 > Fixed bug in antimatter using Russian Roulette sampling.
1510 >
1511 > (Above changes included in 3.7.2 patch release 22 Aug 2005.)
1512 >
1513 > Created fieldcomb script to combine alternate fields in a rendering
1514 > sequence.  (Development generously sponsored by Iebele Abel.)
1515 >
1516 > Added missing preload of mesh objects for more efficient memory use
1517 > during parallel rendering -- this was a serious oversight.
1518 >
1519 > Created ran2tiff program to automate exposure setting of animation
1520 > sequences using a moving histogram in combination with pcond, and
1521 > converting frames to TIFF.
1522 >
1523 > Eliminated SPEED macro from makeall and source tree.
1524 >
1525 > Added -pj option to vwrays to allow jittering of sample locations.
