DeVault: Announcing the Hare programming language

It's not 1.0 yet, and that comes with some obvious caveats. However, it is useful for many kinds of systems programs, has a pretty broad and mostly mature standard library, only a small number of non-disruptive future language changes planned, and lots of docs. There's no test suite to explicitly measure conformance against the (draft!) specification, but the compiler and standard library both have plenty of tests, some of which do directly verify their behavior against the spec.

So yes, it's still a work in progress, and that comes with its caveats, but it's also a lot more fleshed out than you might expect. We're planning on putting a lot of work into 1.0, more than most languages do, because we plan to feature freeze it there. We might have released 1.0 much sooner if not for that.
