Ah, OK.  Makes sense now.  

Yes, the changlog should be more clear that this is referring to a
signal name, e.g. 

       ...there is an 1 sysclk cycle window where the SR_SInterruptz
       signal could be asserted low.

(also note that I think the  "for once cycle" that ends that phrase in
the original changelog is redundant, since it already says a "1 sysclk
cycle window".
