Valve rolled out the Smissmas 2017 update today for Team Fortress 2. The update includes new community-created taunts, new Winter 2017 Cosmetic Case, a Stuffed Stocking gift for all players that log in, a War Paint Case, and just general changes to the game itself.

I didn't have any screenshots from the Smissmas update to share, so the header is from the Jungle Inferno update that came out recently for the game.
