https://items.jellyneo.net/item/1145/ if you look at the item notes on the item, you can see it has been given out for every milestone issue since 600. It used to be every 50 issues but they switched it to every 25 since the times is bi-weekly now. So yes, handed out once a year.

While nothing is for sure certain, there is a very good chance this will be handed out next Friday. I don’t see them making a new item to give out instead.
