1. Nine major changes
Sessions, the handshake and SSE resumption disappear; server/discover, subscriptions/listen, resultType and multi-round-trip retries reshape the operating foundation.
2. Twelve minor changes
Routing headers, cacheScope, ttlMs, error allocation, JSON Schema 2020-12, tracing and OAuth hardening still require concrete implementation work.
3. Four deprecation entries
Roots, Sampling, Logging, HTTP+SSE, two includeContext values and Dynamic Client Registration enter formal replacement paths.
4. Three maintenance changes
The numeric schema correction, feature lifecycle and repository-native SEP workflow affect validators, compatibility policy and release gates.
5. Export only the lens you need
The explorer filters locally and creates JSON or Markdown with public IDs and official links. It excludes search text and requests no code, repository, endpoint or credential.
Frequently asked questions
H/M Blindspot · hogarmas.net
Does the ledger cover the complete official changelog?
Yes. It represents each of the 28 numbered entries once and contract-tests every category total.
Is the candidate already the final specification?
No. The locked target points to July 28, 2026, and this site keeps the final version explicitly unverified.
Does the brief certify compatibility?
No. It summarizes public changes; it does not inspect an implementation or run a conformance suite.
