Linux port of Alex Kan's?

The science done by optimized apps is the same. You don't miss anything. AKv8 is the fastest one.

Are they able to use all work units that 6.03 can use and do they perform the same analysis? Or does 6.03 have a newer, better analysis and with using an older piece of software I might miss signals?
So what made the version numbers rise from 5.x to 6.x?

The graphics for stock builds. 6.x are built with a separate graphics app in order to match what BOINC 6 had to do to work within Windows Vista guidelines.
Note that 6.03 doesn't run on Win95, and Eric Korpela's advice was to use 5.27 with an app_info.xml file. As far as the signal analysis is concerned, any version of setiathome_enhanced back to the 5.1x versions is fine. Credit claims can be enough different to annoy other users, though.
The CUDA app (both stock and the builds included in Raistmer's packages) has some things missing so in some cases it bails out with an "unsupported function" error (though BOINC doesn't know that's what the -12 exit code means so it calls it "unknown").

So it's safe to use 2.4L (SSE only) and pretend having 5.27 ?

It annoys me, too. Credits claimed dropped by roughly a factor of 3, computation time dropped by a factor of 2-2.5. So in the same time I do more work for less credits than with the default app. I guess one needs SSE2 or SSE3 to have enough speedup to compensate the lesser credits with the increased number of WUs.
So I have to decide if I care most about credits, than I use the default app again, or if I care most about science and helping the project, then I stay with the optimized app.
Perhaps I should just try AP, although I guess it will take weeks to figure out if that pays off.
