Short and easy:

“The following improvements have been made to Color 1.0.4.

XDCAM Clip Relinking Is Fixed

XDCAM EX, HD, and 422 clips now relink properly.

ISO Changes in the RED Tab Appear Correctly

Instances where the Color UI did not accurately reflect changes made to the ISO parameter in the RED tab of the Primary In room have been fixed.

Improvements to the Blur Node in the Color FX Room

Adjusting the spread parameter of the Blur node no longer causes the clip to scale up.

Changing ISO on RAW footage is an important and powerful tool – now it (purportedly) works right. Just saw it, haven’t tested it yet myself…

Also, don’t forget, I do NOT recommend 10.5.6 at this time, esp. if you’re a Color user – see previous post…
