FB 1.5 is even more stable than FB 1.0. FB 1.5 is faster the FB 1.0.
And, I have multiple customers that found the difference in
performance between FB 1.0 vs FB 1.5 substantially better. Also, I
have a customer that found FB 1.5 RC7 faster than RC6.

And, no problem issues have been reported.

But, be careful when installing FB 1.5 over FB 1.0. Uninstall FB 1.0
before installing FB 1.5, because the service name has changed.
