When you log into Steam -- if you haven't already done so last night -- you'll be prompted with a rather hefty update.  Unfortunately, the Scout update for Team Fortress 2 is nowhere in sight, but there are other fixes applied with this most recent patch. 

Team Fortress 2 sees the most changes, with a little notation at the bottom of the update list for Day of Defeat: Source.

Team Fortress 2

• Sticky bombs now get a reduced close range damage ramp up (like Rocket Launcher & Syringe Gun)

  • Ultimately reduces damage done by sticky bombs to enemies <512 units from the Demoman

• Moved the unlockable system over to the new item backend:

  • Added a warning dialog to the loadout screen telling clients when the server they're on could not get their loadout

• Made "tf_damage_disablespread" a replicated convar, so clients can see the value of it on the server they're connected to

• Renamed "mp_stalemate_at_timelimit" to "mp_match_end_at_timelimit", to better explain its function now that stalemate is optional

• Fixed muzzle flashes & shell ejections still playing when viewmodels are hidden

• Server tags can now be used to include or exclude servers from the list

Team Fortress 2 and Day of Defeat: Source
Protected several more commands from client exploitation
