SteamDB has spotted a small update for the game:
Size is close to 10 MB. Although unlikely, more info will be edited in if it does become available.
Autograph Avatar levels for The International 10 talent have once again become unobtainium and can no longer be purchased (enforced through both and through in the Compendium)
- Just a reminder, you have until the end of this month to use your levels before they expire, and Autograph Avatars themselves will become tradable and listable on the Steam Community Market early on 11/18/21 (specifically, at 2:00 AM PST/4:00 AM CST/1000 UTC)
