DO11 Defaults

A bit of a pathological question...

I like to keep an OCB for the 'default' settings that I can revert back to when checking on issues or trying to demonstrate to a new user or something... I'm also looking to roll some of the defaults from later betas that have changed during the beta program into my current v11 golden config. Can you say what the following difference in flags tie back to in Prefs?

v11.0.1.0:

settings5="0x100400200"

v11.1.0.0:

settings5="0x600000100400200"
