I use 4.1.4 in a production environment, and I guess many of us also do
so. You might decide to wait for a "final" release, but even GA versions
of MySQL have bugs. Actually all versions have bugs - you might run into
them or might not. The "core" is usually very stable.
Considering the quality of MySQL, I think in most scenarios you can use
it when it reaches beta stage.
