No it's not. Maybe the development is bit slow, because it's not funded by big players. Didn't tried nightly builds, but there is some prerelease available:
It's got commits from 2 months ago, I keep a few projects that go a few months at a time without activity. I wouldn't say it's abandoned, though maybe the devs aren't finding the time for it (or they're preparing some big update that isn't quite ready yet).
