You can ftp the 5.01 patch from ftp://ftp.corel.com/pub/Bryce/5.0.1 Last time I checked, it was still not shown on Corel's website as an update. It lists a few of the fixes. One thing that's not mentioned in the patch, but is fixed, is the problem with the cloud frequency/amplitude graph. Previously if you clicked and drag, the settings jumped to some off-the-wall value instead of starting at the current setting. This made that method pretty much unusable. Also it mentions fixing the tree lab instability. I didn't even mess with it pre-patch, it tended to freeze a lot. If you do network rendering, be sure to grab the lightning update as well, the previous client won't work.
