Portal 2 seemed as tight as Valve games always are when we played through it, but there apparently issues, and Valve has seemingly stamped them out.
The new PC patch fixes a bunch of crashing issues and glitches that got players stuck at certain points in the game.
This follows confirmation over the weekend of details regarding Portal 2's first downloadable content, which will pack new chambers, challenges and more for free.
Here's the patch change list:

# Fixed: Numerous localization bugs and improvements (also added Czech and Turkish localized text)
# Fixed: Overflow bug in keyvalues
# Fixed: Voice functionality regression (voice again enabled by default)
