We recently adopted it to provide a sane base to our Javascript. Personally, I LOVE it. It's cleaned up our code so much.
My problem with it is that it seems to have gone somewhat stale. It's been almost a year since the last update, and at least for the JS target, a number of the great external libraries never made the hop over to the 3.0 codebase.
Development hasn't stalled at all, neither for the JS target nor for most other targets. The core compiler is being improved constantly, which benefits all targets, and there have been improvements in the JS code generator, too (which isn't easy, the code quality has been very high, already).
Oh I definitely have nothing bad to say about Haxe. I was mostly just referring about some of the external libraries that never made the jump over from legacy, which could be indicative of developers jumping ship.
You make a great point; just because a project doesn't put out updates once a week doesn't mean it's stale. There are some other great projects like haproxy and redis that are clean enough and stable enough that regular updates aren't necessary.
I guess you sort of grow accustomed to that mentality when dealing with some other common OSS projects
You should try the nightly builds or compiling straight from Git. They are stable enough for many purposes (and if you report a bug chances are that its fix will soon be available) and you can take advantage of new features.
By the way, there's a new release planned for the next weeks.
