 * FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): support [reusable templates](https://prometheus.io/docs/prometheus/latest/configuration/template_examples/#defining-reusable-templates) for rules annotations. The path to the template files can be specified via `-rule.templates` flag. See more about this feature [here](https://docs.victoriametrics.com/vmalert.html#reusable-templates). Thanks to @AndrewChubatiuk for [the pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2532).
 * FEATURE: [vmctl](https://docs.victoriametrics.com/vmctl.html): add `influx-prometheus-mode` command-line flag, which allows to restore the original time series written from Prometheus into InfluxDB during data migration from InfluxDB to VictoriaMetrics. See [this feature request](https://github.com/VictoriaMetrics/vmctl/issues/8). Thanks to @mback2k for [the pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2545).
 
+* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert.html): proxy `/rules` requests to vmalert from Grafana's alerting UI. This removes errors in Grafana's UI for Grafana versions older than 8.5.*. See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2583.
 * BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): do not return values from [label_value()](https://docs.victoriametrics.com/MetricsQL.html#label_value) function if the original time series has no values at the selected timestamps.
 * BUGFIX: [VictoriaMetrics cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html): limit the number of concurrently established connections from vmselect to vmstorage. This should prevent from potentially high spikes in the number of established connections after temporary slowdown in connection handshake procedure between vmselect and vmstorage because of spikes in workload. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2552).
 * BUGFIX: [vmctl](https://docs.victoriametrics.com/vmctl.html): fix build for Solaris / SmartOS. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1322#issuecomment-1120276146).
