People are legitimately clamoring for V6.1.0, just as they were with 6.0.9.
The betas have remained in limited use because there must still be issues. Overall betas are stable but the speed bump issue (true of other versions of V6), which is dependent on the machines, may be enough to make sure 6.1.0 has corrected this issue and is not with it's own demons. Otherwise there will be a lot of nashing of teeth.
(I am using 6.0.8, didn't see the improvement in 6.0.9 being important enough, thought I would leap frog over it, but admit it is taking longer than I anticipated. I am patient.)
