We're releasing the versions for CPUs first. We'll release versions for graphics processing units (GPUs) and Android devices as they come available. We're releasing slowly so as not to overtax our download server. This update will happen automatically, unless you use a special version you got from another web site.
We've also made small changed to our science code to improve the Gaussian fitting routines. This means version 8 results are not compatible with version 7. So if you use a version of SETI@home you got from another site, or if you compile your own version, you'll need to get or build a version 8 application. I'm sure link will be made available in the Number Crunching forum.
A shout out to the volunteer developers (especially Urs, Jason and Raistmer) and all the beta testers for helping out.
Happy New Year!
