- Requires Erlang 26 – nodes on older Erlang versions will fail to start (breaking change).
- Fixes many bugs in core broker, CLI tools, MQTT, management API and several plugins (e.g., resilient quorum queue ops, faster shutdown, corrected MQTT timestamps, duplicate‑key issue).
- Adds minor feature enhancements such as optional OpenID Connect logout, extra TLS client settings, JMS Topic Exchange state storage and updates ra dependency to 2.10.0.
