Due to the nature of the balance changes the NS team is making in NS v3.2, they decided to open up testing in a public beta so they can get more feedback. Installing the beta will not interfere with your current NS install so clan players and others can continue playing without being affected. There are a lot of changes in v3.2, including four new maps, quite a few interface changes, HLTV improvements and more. The full changelog is here, and we suggest you read it while you download to avoid confusion!
