SkyNews on Foxtel carried an interview with a pax on the flight who said there was a noticeable pressure change. ABC news article here:

Visions of the captain being sucked out like that BA BAC 1-11 in England a few years ago probably elicited a rapid control input and quick tightening of the five-point harness...
I suspect the pressure change noticed by the pax was due to the quick descent and catching the cabin which always hurts a bit, rather than an actual hull breach via the cracked windscreen.
...But for the facts, we will have to wait for the enquiry.
