# 12.29.0

* **Batched outbox publishing** — Messages are now fetched and published in configurable batches, improving throughput.
* **Outbox circuit breaker** — Automatically stops polling when the message broker is unavailable and resumes once connectivity is restored.
* **Outbox health indicator** — Exposes outbox publisher status via `/actuator/health`.
* **Suppress outbox for Object Management** — A `suppressOutbox` property can be set on object management configurations to skip outbox writes for read-heavy integrations.
