Welcome to the Beta Test 3.0 Download Page

Below are beta versions of the SETI@home 3.0 client. Though the eventual release number will be 3.0, the current build number is 2.66. Please click on the appropriate links to obtain the right versions for different operating systems.

Please note that you should download the software now because you will not be allowed to return to this page at a later time.

The Mac and Windows versions work just like regular SETI@home installers, in that you shouldn't have a current client running when you install the new software, and you will lose your current work unit in progress (you may want to wait until it's done). Hopefully things will be self explanatory.

The big change in 3.0 is vastly improved science - we are now searching for pulses and triplets as well as spikes and gaussians. Web pages describing these in more detail will be up soon on the main home page. Other improvements include optimized FFTs (for faster analysis of wave data) and various bug fixes.

Any and all feedback is welcome. Even if you have nothing but positive things to say. We want to know if something is working or not. Please send all comments to us via e-mail (beta@setiathome.berkeley.edu), but keep in mind we may not be able to respond immediately.

And now, the moment you've been waiting for.. The new clients!
