WRKJRNA Change - V5R2 or Security Level 50?

We recently moved to V5R2.  Shortly afterwards we moved to security level
50.   Today we noticed that WRKJRNA has changed:  before F13 displayed the
journaled files, and several options were available by putting a number next
to the journal receiver.   

The new screen looks like this:

                         Work with Journal Attributes

 

Journal  . . . . . . :   MIJ010JL        Library  . . . . . . :   PRDDTA1

Is this something I missed when we did the V5R2 upgrade, or due to changing
to security level 50?    I suspect that it is due to security level 50, as
we've been on V5R2 for almost a month and I should have noticed if that
caused the change.    We went to security level 50 on Memorial day, so that
seems the more likely cause to me, but my manager is suprised that a
security level change would cause the screen layout to change.  

I don't have a problem with it, we just want to know what caused the change.
