[Wine] updating wine version?

[tparker]

I have stuck with an older version of wine because it ran everything 
wine-compatible that I needed and didn't give me any trouble, but the 
newest WOW update won't even let me into the log in screen and the only 
fix I have found and not tried is to switch to a newer wine version 
(although that seems to be crashing a lot for people, but that looks 
more like a WOW problem than a wine one).

I'm not having luck finding anything online that gives me clear-to-a 
linux-newbie instructions for how to change versions. Can anyone point 
me to something? I found some instructions on the wine-wiki but ran into 
trouble getting them to work, all I could find on the Ubuntu forums 
stayed with the older versions in the repositories.

Also, should I be using the absolute newest wine version or is one 
slightly older more stable?
