+## [v0.48.2](https://github.com/VictoriaMetrics/operator/releases/tag/v0.48.2) - 27 Sep 2024
+
 - [operator](https://docs.victoriametrics.com/operator/): properly expose `vm_app_version` metric tag with `version` and `short_version` build info. It was broken since v0.46.0 release.
 - [operator](https://docs.victoriametrics.com/operator/): changes default value for `controller.maxConcurrentReconciles` from `1` to `5`. It should improve reconcile performance for the most installations.
 - [operator](https://docs.victoriametrics.com/operator/): expose new runtime metrics `rest_client_request_duration_seconds`, `sched_latencies_seconds`. It allows to better debug operator reconcile latencies.
