Team Fortress 2's Jungle Inferno update will launch today

Normally it’s pretty hard to halt an inferno, but Team Fortress 2’s Jungle Inferno update, which was meant to launch yesterday, seems to have been more of a small blaze. Valve is rectifying this, fanning the flames and adding some finishing touches, and it should be out today.

“Typically we ship updates on a Thursday, so those of you expecting the Jungle Inferno Update to flip live today, you might want to sit down for this next part,” a post made yesterday reads. “If you're already in a comfortable sitting position, you might want to sit up straighter, because we're about to tell you we're delaying a day and we don't want you to twist your lumbar.”
It’s almost finished, but Valve’s doing some stress testing right now. It will launch early today, says the developer.

When it does arrive, you’ll be able to check out the new map, Mercenary Park, along with a bunch of community maps, taunts, war paint and Pyro items.
