 ## tip
 
 * BUGFIX: [cluster version](https://docs.victoriametrics.com/victorialogs/cluster/): evenly spread rerouted data across available `vlstorage` nodes. Previously, healthy nodes adjacent to unavailable nodes in the `-storageNode` list could receive much more data, resulting in uneven resource usage. See [#1548](https://github.com/VictoriaMetrics/VictoriaLogs/issues/1548).
+* BUGFIX: [data ingestion](https://docs.victoriametrics.com/victorialogs/data-ingestion/): keep the [`_stream` field](https://docs.victoriametrics.com/victorialogs/keyconcepts/#stream-fields) in sync with [extra fields](https://docs.victoriametrics.com/victorialogs/data-ingestion/#http-parameters) passed via the `VL-Extra-Fields` header. Previously, an extra field overriding a [stream field](https://docs.victoriametrics.com/victorialogs/keyconcepts/#stream-fields) value left the original `_stream` tags unchanged. See [#1571](https://github.com/VictoriaMetrics/VictoriaLogs/issues/1571).
 * BUGFIX: [data ingestion](https://docs.victoriametrics.com/victorialogs/data-ingestion/) and [querying](https://docs.victoriametrics.com/victorialogs/querying/): properly handle logs containing duplicate [stream field](https://docs.victoriametrics.com/victorialogs/keyconcepts/#stream-fields) names. Previously, [v1.52.0](https://github.com/VictoriaMetrics/VictoriaLogs/releases/tag/v1.52.0) could panic when ingesting such logs in single-node VictoriaLogs, drop them during ingestion in VictoriaLogs cluster, or panic when querying such data written by earlier releases. See [#1603](https://github.com/VictoriaMetrics/VictoriaLogs/issues/1603) and [#1604](https://github.com/VictoriaMetrics/VictoriaLogs/issues/1604).
