      External Alert Source allows to override the Source link for alerts sent to AlertManager for cases where you want to build a custom link to Grafana, Prometheus or any other service. Supports templating - see https://docs.victoriametrics.com/vmalert.html#templating . For example, link to Grafana: -external.alert.source='explore?orgId=1&left=[\"now-1h\",\"now\",\"VictoriaMetrics\",{\"expr\": \"{{$expr|quotesEscape|crlfEscape|queryEscape}}\"},{\"mode\":\"Metrics\"},{\"ui\":[true,true,true,\"none\"]}]' .

 * BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert.html): fix panic if `vmagent` runs with `-clusterMode` command-line flag in [multitenant mode](https://docs.victoriametrics.com/vmalert.html#multitenancy). The issue has been introduced in [v1.82.0](https://docs.victoriametrics.com/CHANGELOG.html#v1820).
 * BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): do not show invalid error message in Kubernetes service discovery: `cannot parse WatchEvent json response: EOF`. The invalid error message has been appeared in [v1.82.0](https://docs.victoriametrics.com/CHANGELOG.html#v1820).
 * BUGFIX: `vmselect`: expose missing metric `vm_cache_size_max_bytes{type="promql/rollupResult"}` . This metric is used for monitoring rollup cache usage with the query `vm_cache_size_bytes{type="promql/rollupResult"} / vm_cache_size_max_bytes{type="promql/rollupResult"}` in the same way as this is done for other cache types.
-* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert.html): fix escaping of query params when using `external.alert.source` flag.  See this [issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3139).
