Valve has announced a major Steam update featuring "hundreds of changes" designed to improve the user interface, performance and functionality of the digi download service.
An opt-in beta for the update - which introduces library customisation tools for sorting games and allows users to track all of their achievements "in a standardised cross-game fashion", among other features - is now available.
"We made hundreds of changes to the Steam client as a result of customer feedback on the interface, performance, and functionality," said Steam dev director John Cook.
"For example, we swapped out the Internet Explorer rendering engine with WebKit, which gives us a bunch of size, stability and performance benefits. This release of Steam leaves us well prepared for another year of strong growth."
Valve also said that Steam has grown by 200 per cent in the last year and now commands 25 million users and offers over 1,000 games.
