First, it would be my position that all software that is commonly available and used by end-users should be on topic. This specific piece of software has always been declared "alpha" by the creators. That's partly because they're so far from their own goal. The software saw its initial release in 1998. Over 20 years ago. ReactOS isn't "all-but-abandoned" in fact, there are 150 developers/users right now on IRC (Freenode/#ReactOS). That's 10% the size of Debian. The project has hundreds of committers on Github. This month it became self-hosting and was written about in The Register (which turned me onto it), and other publications
- ReactOS 0.4.9 release metes out stability and self-hosting, still looks like a '90s fever dream
- Btrfs now boots ReactOS, a free and open source alternative for Windows NT
- ReactOS 0.4.9 eleased
