I noticed that, but I actually prefer the new matte finish paper. In my opinion, easier to read and possibly more recyclable. I hope they stay with the new paper.
My collection of QST's has overwhelmed my storage ability, so I'll be keeping 5 years and recycling the older ones unless I can find someone interested.
The last few issues have been arriving in an envelope. They arrive in better shape than in the past, but I suppose the downside in increased mailing costs.
