Since I still have both cans, I checked the June Tailor. For the most part, the text is pretty much the same (and both are suitable for both cotton and polyester) until you get to this point on the back. The old can stopped after positioning the fabric and it being tacky. After that the new can says:
Laundering will remove or diminish adhesive properties. Dry clean to remove completely.
I know I over-sprayed in the beginning and I think most people do. There's a fine and rather precise balance for me to get enough spray to hold everything securely but light enough to dissipate. If I'm giving the gift on a timeline, I like to be done complete with first washing two weeks before gifting just to make sure most of it gets out. Too much and too soon a wash and you can get sticky lint/thread worms on the quilt.
The last project I did with the new can that smelled so strongly to me I let sit for a week before I began and it held together pretty well. I was using pretty puffy batting and don't feel it held too securely to it so I did put in a just a few (like 10-12) pins until I got a couple of stabilizing rows in. It's been about 4-6 weeks now I think and I'm finishing up the hand sewing of the binding (no, it doesn't really take me that long! been busy on other things) and I no longer notice any odor. If there is anything report after I wash it, I'll report back.
