Valve has been working hard on a brand new Steampowered Store that makes browsing easier and adds some new features to it aswell. One of the main new things is that you can immediatelly browse by game genre, check for free stuff and you’ll get a better overview of the most important things.
We expect the new update to be ready next week. It is not known yet if Valve will also release a new client with this update.
