A new update for the PC and Mac versions of Portal 2 is now live on Steam, offering a number of bug fixes.

The patch, which will be applied automatically when you restart your Steam client, smooths over a few glitches and makes a couple of minor gameplay tweaks.

Here's the full list of changes:

Released this week on PC, PlayStation 3 and Xbox 360, Portal 2 scored a perfect 10/10 from Eurogamer's Oli Welsh.

However, its launch hasn't been incident-free – a number of users decided to shellac the PC version's Metacritic user score page, claiming the game was too short, featured excessive DLC and was a port of the console game.
