An update to Team Fortress 2 has been released. The update will be applied automatically when you restart Team Fortress 2. The major changes include:

• Added a new tag "Halloween 2013" to the Steam Workshop publish UI
• Fixed the Flex target preview in the Steam Workshop item import tool
• Fixed The Professor's Pineapple not drawing correctly for players in DirectX8
• Updated the teamplay_round_win event to fill out the winreason and flagcaplimit fields
  
  Notes missed from Monday's update:
• Updated Sentry Busters in Mann vs. Machine mode to damage teammates when they explode
• Switched Windows clients to use SDL 2.0 for controller support which enables hot-plugging controllers and configuring them through Steam Big Picture settings
