PhazePyre has just posted findings from the latest patch update, this is now live on the test server but as yet is unconfirmed if all changes will carry forward to live.

Locale
  • Item Name
    • Gas Grenade
    • Smoke Grenade
    • IO.Door.RestaurantDoor01
      • I feel like this may be an incorrect addition to the Locale files?
    • Renamed Flashbang to M-84 Stun Grenade
  • Item Description
    • Once deployed, the Smoke Grenade will emit a large cloud of Smoke that can be used to cover tactical movements.
  • General
    • [[key]] Claim [target]
    • You may not build structures in the quarantine area.
      • Quarantine area?! What does this mean!?
    • [[key]] Undo placement of [target]
      • *I really hope this put the structure into your inventory again, but I hope they take into account inventory space and have a "You don't have enough space to undo placement".
