entries:
  - version: 1.19.1
    type: patch
    highlights:
      - Use mppx's public SSE session-controller type for metered streaming routes.
  - version: 1.19.0
    type: minor
    breaking: true
    highlights:
      - Enforce CAIP-2 network identifiers at the type level; new exported X402Network type (`eip155:${string}` | `solana:${string}`).
      - Friendly names like 'base-sepolia' are now rejected at compile time instead of throwing at construction.
      - Documented the keyless local-dev path; placeholder CDP keys serve correct 402 challenges via the hardcoded facilitator baseline.
  - version: 1.18.0
    type: minor
    highlights:
      - Add conditional settlement via `beforeSettle` returning 'skip' — a paid route can return its 2xx body without charging.
