 * FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): add `exported_` prefix to metric names exported by scrape targets if these metric names clash with [automatically generated metrics](https://docs.victoriametrics.com/vmagent.html#automatically-generated-metrics) such as `up`, `scrape_samples_scraped`, etc. This prevents from corruption of automatically generated metrics. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3406).
 * FEATURE: [VictoriaMetrics cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html): improve error message when the requested path cannot be properly parsed, so users could identify the issue and properly fix the path. Now the error message links to [url format docs](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#url-format). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3402).
 * FEATURE: [vmctl](https://docs.victoriametrics.com/vmctl.html): add ability to copy data from sources via Prometheus `remote_read` protocol. See [these docs](https://docs.victoriametrics.com/vmctl.html#migrating-data-by-remote-read-protocol). The related issues: [one](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3132) and [two](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1101).
-* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): add `remoteWrite.sendTimeout` command-line flag to configure timeout for sending data to remote write URL. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3408)
+* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): add `-remoteWrite.sendTimeout` command-line flag, which allows configuring timeout for sending data to `-remoteWrite.url`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3408).
 
 * BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert.html): properly pass HTTP headers during the alert state restore procedure. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3418).
 * BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert.html): properly specify rule evaluation step during the [replay mode](https://docs.victoriametrics.com/vmalert.html#rules-backfilling). The `step` value was previously overriden by `datasource.queryStep` flag.
