+- [#15383](https://github.com/emqx/emqx/pull/15383) Fixed a potential resource leak in the MQTT bridge. When the bridge failed to start, the topic index table was not properly cleaned up. This fix ensures that the index table is correctly deleted to prevent resource leaks.

 - [#14989](https://github.com/emqx/emqx/pull/14989) Optimized the Kinesis Connector and Action to significantly reduce the number of AWS API calls during startup and health checks. This change helps prevent exceeding AWS Kinesis API rate limits (e.g., `ListStreams` and `DescribeStream`), which previously led to frequent health check failures when using larger connection pools or multiple connectors.
 - [#15299](https://github.com/emqx/emqx/pull/15299) Fixed a `badarg` error that occurred when exporting OpenTelemetry metrics.

+### Enhancements

+- [#15331](https://github.com/emqx/emqx/pull/15331) Fixed an issue in the InfluxDB action where line protocol conversion failed if the `timestamp` in `WriteSyntax` was left blank and no timestamp field was provided in the rule.
+  Now the system's current millisecond value is used instead, and millisecond precision is enforced.
+- [#15274](https://github.com/emqx/emqx/pull/15274) Improved the resilience of Postgres, Matrix, and TimescaleDB connectors by triggering a full reconnection on any health check failure. Previously, failed health checks could leave the connection in a broken state, causing operations to hang and potentially leading to out-of-memory issues.
+- [#15224](https://github.com/emqx/emqx/pull/15224) Fixed an issue where updating an External Schema Registry via the Dashboard would unintentionally overwrite the existing password with `******`. The password is now correctly preserved during updates.
