I've noticed something strange in v2.0 beta (I've updated to the latest Dec 25th release and the problem remains).
In both 1.8.5 and 2.0 I have enabled the option:
Preferences > Advanced > Load camera orientation angles from XMP metadata
In 1.8.5 this loads Yaw, Pitch, Roll from the XMP metadata.
In 2.0 this only loads Yaw. Pitch and Roll are always 0 (zero).
It's strange that it does load Pitch, but not the other two.
Thank you.
