Score: 7.0/10 (Innovation: 7, Technical: 6, Documentation: 8, Utility: 7)

ChangeSpec defines an open standard JSON format for software change notifications, such as API breaking changes, security advisories, and terms of service updates. It aims to provide a consistent, machine-readable contract layer similar to CloudEvents or OpenAPI but focused on change communication. Its combination of a formal specification, multiple reference implementations, and transport bindings addresses a clear gap in the ecosystem.

Target audience: backend devs, devops, platform engineers
