Hello BCM community friends.
I see in the SU list that the BCM450.R100.SU.System-016.201110 is available for BCM450R1 now while i have in my files the BCM450.R100.SU.System-017.201205-1.
Does anyone know if the 017 was removed due to bad build? or something similar?
Why the active SU is the 016 while there is the 017 released?

Thanks
