 * FEATURE: leave the last raw sample per each `-dedup.minScrapeInterval` discrete interval when the [deduplication](https://docs.victoriametrics.com/#deduplication) is enabled. This aligns better with the [staleness rules in Prometheus](https://prometheus.io/docs/prometheus/latest/querying/basics/#staleness) comparing to the previous behaviour when the first sample per each `-dedup.minScrapeInterval` was left.
 * FEATURE: [VictoriaMetrics cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html): add ability to disable peer TLS certificate verification with `-cluster.tlsInsecureSkipVerify` command-line flag. See [mTLS docs](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#mtls-protection) for details. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2490).
 * FEATURE: add a handler for `/api/v1/status/buildinfo` endpoint, which is used by Grafana starting from v8.5.0 . See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2515).
+* FEATURE: add ability to proxy alerting API requests from Grafana to vmalert by passing `-vmalert.proxyURL` command-line flag to single-node VictoriaMetrics or to `vmselect` at cluster version of VictoriaMetrics. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1739).
 
 * BUGFIX: export staleness markers as `null` values from [JSON export API](https://docs.victoriametrics.com/#how-to-export-data-in-json-line-format). Previously they were exported as `NaN` values. This could break the exported JSON parsing, since `NaN` values aren't supported by [JSON specification](https://www.json.org/).
 * BUGFIX: [VictoriaMetrics cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html): close `vmselect->vmstorage` connections if they were idle for more than 30 seconds. Expose `vm_tcpdialer_conns_idle` metric at `http://vmselect:8481/metrics` with the number of idle connections to `vmstorage`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2508).
