I'd be grateful if someone could say a bit about why GNUnet is interesting. I looked at it some 4-5 years ago for some P2P work, and concluded at the time that it was entirely unsable. Has much changed?
> For users, GNUnet offers anonymous and non-anonymous file-sharing, a fully decentralized and censorship-resistant replacement for DNS and a mechanism for IPv4-IPv6 protocol translation and tunneling (NAT-PT with DNS-ALG).
Even strict adherence to semver allows this because the major version is 0. You can do anything you want until your 1.0 release. https://semver.org/ says:
> Major version zero (0.y.z) is for initial development. Anything MAY change at any time. The public API SHOULD NOT be considered stable.
That said, the GNUnet project has never, AFAIK, said they are following semver. Semver isn't the only versioning scheme around.
