A look at the PyPy 2.0 release
Minix used to be a simple OS for teaching OS concepts (not researching, AFAIK). It tries to be usable as a general purpose (embedded) OS now, so that's not really an excuse anymore.
The Hurd is GNU's replacement for Unix, not a research project.
Research OSs may not go anywhere in most cases, however that does not make OSs that are not going anywhere research OSs.
MINIX 3.2.1 released

True IMHO for Minix before the 3.0 release.

Yeah, but I would consider the resilience work done via the EU grant mentioned above in a comment puts it into the research OS space. It certainly tries to be embedded, but I think AST is kidding himself if he believes that he can outcompete the BSDs, much less Linux or commercial options like QNX if one desires a pure RTOS.

Well, it certainly started out as a intended Unix replacement to complete the GNU ecosystem since a GPLed kernel was the last missing piece. But looking at its history and detours with the attempted replacement of Mach with L4 and Coyotos I think they definitely strayed into the research space. It was probably never intended that way, but things tend to change a bit over 20 years :).

Yep. I still think it applies to both the current Hurd as well as Minix 3.0 to some extend, but the discussion about what is a research OS and what not is about as decisive as talking about hybrid kernels (see ), i.e. the NT as well as OSX kernels are prime example where nebulous claims just cloud up the whole discussion.
