Not the very latest, but still 4.1 (thanks to Edgar by the way)

I would do so if I could, but it is not easy. At the moment muO is an 
application, not a package: it changes many things in the host image, 
including appearance, behavior of menus, and many small 
improvements/fixes (IMO of course) which make it difficult to coexist 
with some packages.

The solution would be to break muO into core components (compatible, 
without side-effects, suitable for FunSqueak) on one side, and 
dispensable look&feel components on the other side. I'll do so in the 
future, but I don't know when...
