The latest Team Fortress 2 blog entry contains news about the next update that will be released within the next few days. Dispenser and teleporter level upgrades are among the new features with the next update. The Team Fortress 2 website lists the following updates:

• Teleporters will be upgradeable to level 3. As the teleporter is upgraded, the cooldown will decrease.
• Dispensers will be upgradeable to level 3. They will heal faster and generate metal faster as they are upgraded.
• Spies will be able to recharge their cloaking ability by picking up ammo off of the ground.
• We've made a bunch of minor changes by adding particle systems and upgrading the HUD to show things like deaths by critical hits, players that are overhealed, and giving more information to medics when people are calling for them.

There is also news about the next class pack that will be released, this time it's the Scout's turn. BONK! Visit the official Team Fortress 2 website for all the details.
