- rename section 1 to reflect contract-frozen (not bit-immutable) tags - document rolling-tag flip as the breaking-change event - require otel/grpc extensions installed but not loaded by default - state dev images are rebuilt on the FrankenPHP variant - add emergency exception to the one-version-per-year rule - flag ONBUILD reliability under BuildKit as verify-before-GA - call out v1 entrypoint change for the deprecation notice
