Sure it it -- it's had quite a few releases. Just because stuff
depends on unstable releases of libraries, doesn't mean it's not been
released. I was playing with it in Fedora 11 and now use it every day
using F12 alpha.

I still support 0.4.x and 0.5.x, but 0.4.x is is feature freeze and
bug-fix only mode. 0.5.x is where all the cool new stuff happens.
0.4.x will be deprecated when 0.6.0 is released.

I don't think that's a really good idea, I mean, the only_trusted
stuff is very important in 0.5.x.
