[ANN] Ultra 0.3.4 released

[W. David Jarvis]

Hey all - 

This is, tbh, not a particularly impressive release, and is mostly just keeping the project's dependencies up-to-date. It does clear some of the way forward for future ClojureScript support in Ultra, but it's not quite there yet. Still, for those feeling in need of a refresher (especially if you weren't already on 0.3.3), go nuts! :)
