Hi Sean - thanks for the great question! For module and addon products, there is a patch notification on the game page to notify you of an update to your game. For art packs, this does not exist. It is entirely up to creators how they manage their publicity around launches and updates. They are always welcome to include patch notes in their product, update their product page description to show patch notes, post on the marketplace forums, etc. There is no built in, opt in way for creators to notify anyone who has purchased, and that is a great suggestion for both general and the suggestion forums!
