Sugar vs Sugar-0.84 on Karmic

[David Robert Lewis (ethnopunk)]

I've finally done a complete upgrade and am curious to see where the 
Ubuntu Sugar project is in  terms of Karmic

There are now two different version of sugar in the repos. Sugar and 
Sugar-84. Which one do you recommend for ordinary users of karmic?  
Would I be correct in assuming Sugar is now stable, and .84 is purely 
development?

Regards
