This minor release includes the following changes:

New Feature

• Enhanced the HTTP Kill API to allow terminating sessions for a specific tenant user or all sessions associated with a tenant. For more details, check the API documentation.

Improvements

Clustering

• Optimized recovery speed by not caching unresolved InetAddress when the hostname cannot be resolved temporarily.
• Improved clustering stability by retrying domain resolution with a timeout when joining the clusterConfig.clusterDomainName. The timeout is controlled by the system property cluster_domain_resolve_timeout_seconds.

Docker

• Reduced the final image size by using a smaller base image and optimizing layer instructions.
• Included necessary tools for diagnosing various networking issues.

Others

• Improved backpressure protection by considering heap usage and slowdown timeout.
• Introduced a dedicated event type, 'OutOfTenantResource,' to signal when a tenant hits the resource limit.
• Adjusted the upper bound for MaxUserPayloadBytes to 256MB to comply with the MQTT specification.
• Support building with OpenJDK 22 (#86 ）
