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 +
