Spitfire 0.24.0 release notes
Released: 2026-10-10
- NATS step: core publish, subscribe (shared with a queue group) and request/reply; publish to JetStream (measured to the stream's ack) and consume from a pull consumer (a durable consumer shared by the runner's VUs, created to start from new messages when missing). Publishes are stamped: steps that wait for messages or consume from JetStream measure nats_e2e_latency for the same runner's messages (as with Kafka).
- NATS connection type: servers; user/password, token, NKey seed or a .creds file (stored encrypted); TLS; shared connections per runner or one per VU; JetStream domain.
