Via HLDS:
Valve- Fixed the firing speed for the Pretty Boy's Pocket Pistol (now faster)
- Fixed a client/server crash related to contracts
- Fixed a server crash related to taunting
- Updated The Dragon's Fury such that extinguishing a teammate will return 20 health to the Pyro, matching other flamethrowers
- Abandon/disconnect dialogs now show controller hint icons when Steam Controller is active
- Removed trade restrictions from the Prinny items
Rumor has it:
- HUD file updates for those dialogs, and local syncs of Steam Datagram system configuration changes and the item schema: https://github.com/SteamDatabase/GameTracking-TF2/commit/4f7b3c9b10232e4a6c42fb96b3b77361f4b296eb
