It's normal, the timeline will keep changing even after you receive an interview notice. Next thing you are going to see is your interview appointment notification.
I'm in TX and filed in October as well, I did my interview on Monday and now awaits Oath ceremony date. In fact, after my interview, the timeline still showed 12 months to decision.
Based on what I've seen with October filers, you might be close to receiving your interview appointment soon.
I wish you all the best.
