Basic info

Project name: GNU Hurd
Project link: https://www.gnu.org/software/hurd/

Qualifications

ZeroVer's patent-pending zero-based versioning
scheme can obviously be used by everyone, but not every usage is
necessarily notable. Check that the first and at least one other
criterion apply:

• A current ZeroVer-compliant version (0.*) or long history of ZeroVer usage, and
• Very wide exposure (i.e., 1,000+ GitHub stars), or
• Active promotion as part of a paid product or service (e.g., Hashicorp Vault), or
• Relative maturity and infrastructural importance (e.g., Compiz, docutils)

Additional notability info

It's GNU Hurd.

Citation info

https://en.wikipedia.org/wiki/GNU_Hurd says "Initial release: 1990". I couldn't corroborate this, so I'm going with initial release being 0.1 according to their history page. I'm also taking release count from that page.
