[Wine] Wine for Umbutu - Beta packages???

[PeterAnton]

On the Wine download page for Umbutu, it warns that the packages are Beta. 

I'm new to both Wine and Umbutu and have not yet tried to install either.  I read something about Umbutu having Wine repository files?  Does Umbutu include Wine?  Or is it just ready to accept Wine as an add-on.  Are there any stable versions of Wine for Umbutu?  If so, where do I get them?
