IRS Mail Alert: Just Got USPS Informed Delivery Notification After Waiting Since February - Anyone Else?

Finally got movement on my refund! Just received a USPS informed delivery notification showing mail coming from the IRS. Been waiting since February and this is the first update I've seen. I just checked my Informed Delivery app today (Thursday, Dec 7) at around 4:24 PM and saw that I have mail and packages arriving soon - specifically "1 Mailpieces" and "1 Packages" according to the app. The most exciting part is that there's an item from "INTERNAL REVENUE SERVICE" with status "Pre-Shipment USPS Awaiting Item" as of Dec 07 at around 3:24 PM CST. This is the first movement I've seen on my USPS Informed Delivery since I filed back in February. The notification just shows "Pre-Shipment" status, so I'm guessing they've created the shipping label but haven't dropped it off yet. Anyone else get something in the mail recently from the IRS? I'm trying not to get too excited but it's hard not to hope this is my refund and not just another delay letter. After waiting for over 10 months, I'm really anxious to see what this is! I checked all my other USPS features (Quick Tools, Send, Receive, Shop, Business, International, Help sections) but there's no additional info beyond what's in the Informed Delivery section. The app just says "Delivery Date Unknown" which is making the wait even harder!
