Recently I noticed that dry hops suddenly are contributing IBUs in the recipe calculator. I was working out the hop bill for a bitter and noticed I had to use alarmingly little bittering hops to keep it within the expected range. I looked at several of my past dry hopped recipes and saw that they showed no IBU contribution from dry hops, but if I edited a previous one and saved it with no other changes, the IBUs jumped from 74 to 86 as it started counting the dry hops, at around 3% utilization? I wasn't able to find any explanation, release notes, etc for this change. I have read articles suggesting that dry hopping does add bitterness, and I might presume that's what's happening here, but I wanted to sanity check since I'm suddenly seeing large discrepancies and I want to know what I should listen to, here.
