New update out.

[Vampie Cakes]

Updates to Team Fortress 2 have been released. The updates will be applied automatically when your Steam client is restarted. The specific changes include:

Team Fortress 2

    * The Engineer's teleporters can now be upgraded to level three. It will recharge faster the higher level it is
    * The Engineer's dispensers can now be upgraded to level three. It will give out metal and heal faster as it is upgraded
    * Spies will be able to recharge their cloaking ability by picking up ammo off of the ground or from health cabinets
    * Some changes to the second part of the first stage of Goldrush to give the attackers more of an advantage
    * Any weapons that fire bullets (shotguns, sniper's machine gun, heavy's minigun, etc.) can now break apart the Demoman's stickybombs
    * The icon on the HUD for a person calling for Medic will now give more information to the medic (if the target is low on health, on fire, etc.)
    * Added an achievement tracker that will allow people to choose specific achievements that they are trying to get
    * There is now a custom icon for death messages when the player was killed from a critical hit
    * Added a new particle effect for when a player enters the water
    * Added smoke to the feet of a rocket jumping soldier
    * Players will now have some particles swirling around them so other players can see when they are overhealed.

[Je$t]

well they don't do damage when you shoot them.  they just explode and go away.

Medic fires needles from the needle gun and Blutsaugher.

I don't know if that counts , so further testing needed on that as well as midair sticky destroying.
I'm thinking it only applies to sticky traps just a guess though.

If you look at the TF2 Blog , scout gets the next upgrade.
