Team Fortress 2 major update released and source available for modders via the Source SDK

It wasn't just Counter-Strike: Source and Day of Defeat: Source that received big updates today, as Valve also published a new update for Team Fortress 2 along with updating the Source SDK to include TF2! This is a big one for modders, since you now have the source available for TF2!

As announced on the official TF2 website, having the Source SDK updated to include "all the Team Fortress 2 client and server game code" means modders can do a whole lot with it. This includes building entire conversions, which can be released on Steam. This SDK is under a "non-commercial basis" so everything made with it must be free. Valve included a little word on TF2 items though:

Players have a lot of investment in their TF2 inventories, and Steam Workshop contributors have created of a lot of that content. The majority of items in the game now are thanks to the hard work of the TF2 community. To respect that, we're asking TF2 mod makers continue to respect that connection, and to not make mods that have the purpose of trying to profit off Workshop contributors' efforts. We're hoping that many mods will continue to allow players access their TF2 inventory, if this makes sense for the mod.

Fixed player voice commands being abruptly ended when the player enters shallow water

It's funny to see a bug that originates from Quake (later transported to Quake 2) carry on this far long into TF2's lifetime. In Quake, it was often used to your advantage to hide jump sounds since you exited the water shortly after jumping from shallow water.
