ArgoUML is arriving the next stable release. Its a very interesting time since this is the first version that we have support of UML 1.4 and XMI 1.2 with the MDR library. The active core developers base has grown now with Ludo and Tom (kudos to them), which makes a big difference. We have development in installers and the new ArgoUML AndroMDA module.
I wouldn't say that our sail is fully inflated by a good steady wind, but, we're certainly going in that direction :-))
