Versioning & Changelog
Versioning policy
AIEP is intended to be stable. The web is built on interfaces that persist. AIEP therefore treats versioning as a core discipline.
What gets versioned
- schemas (semantic versioned, pinned per artefact via
protocolVersion/ R8) - protocol specification (current: 1.0)
- registry surfaces and policy documents
- canonical scoring coefficients α, β, γ (registry-versioned with Merkle proof)
- GENOME kernel (frozen —
GENOME_LOCKFILE.jsonbinds each deployment to a specific kernel version)
Compatibility
Breaking changes introduce a new major version. Old endpoints remain accessible or redirected. The meaning of an existing version is never altered silently — AI retrieval systems depend on stable, deterministic behaviour across time.
Changelog
Early public release. The Hub is live and actively being built. Specs, tooling, and integrations are shipping continuously. Entries below reflect what is published and confirmed.
