Valve are like master chefs: always dabbling, always sticking their fingers in the pot, making sure everything is just right. Which is why they released a big Team Fortress 2 patch today.

There are bug fixes, there are gameplay tweaks, and there are slight changes to the Spy's abilities, for whom side-stabbing has returned and who will now automatically show the primary weapon of their disguise when activated.

The full patch notes are below:

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

Gameplay changes

Added a duck timer that prevents duck spamming while running around on-ground

In-air, players are only allowed to duck once before they touch ground again

Fixed several bounding box issues with jumping, falling, and rocket jump air-walking. Bounding box should be much more accurate there now

Increased backstab check so that Spies can side-stab again

When disguising, Spies now always start showing the primary weapon in their disguise, and can then switch it with the last-disguise key

TF2 Fixes

Fixed flamethrower loophole that resulted in the flame effect being stuck on while the flamethrower wasn't really firing

Fixed exploit that allowed players to circumvent the force-fire timeout on the pipebomb launcher

Fixed a bug that caused Natasha's slow on hit effect to be inverted from 75% to 25%

Restored sawmill_logs.mdl file, fixing some user maps that used it

Fixed some localization issues with Scout achievement strings

Removed the "Final" phrasing in the map loading screen

Engine fixes

Fixed a server crash on startup under Linux

Fixed a buffer overflow issue related to network string tables

Gamestats uploading is now done asynchronously. This fixes the client timeout issues on map changes

CP_Junction

Fixed an exploit where engineers could build a teleporter exit in an invalid area

Fixed a few bad overlay assignments and other minor issues
