Yes, for 8.0 in all predefined PhysicsLits gamma-nuclear interaction is ON 
by default, it is written in release notes. We choose this variant of 
defaults, because there are no visible CPU penalty, if this physics is 

About synchrotron radiation: we choosed OFF by default (as it was before), 
because field is not exist in each application.

Can you, please, briefly describe your application, so for better 
understanding what users need.
