-**Update notes:** [vmalert](https://docs.victoriametrics.com/vmalert.html) by default hides values of `-remoteWrite.url`, `-remoteRead.url` and `-datasource.url` in logs and at `http://vmalert:8880/flags` for security reasons. See the corresponding SECURITY change in the Chagelog below for additional info.
+**Update note 1:** [vmalert](https://docs.victoriametrics.com/vmalert.html) by default hides values of `-remoteWrite.url`, `-remoteRead.url` and `-datasource.url` in logs and at `http://vmalert:8880/flags` for security reasons. See the corresponding SECURITY change in the Chagelog below for additional info.
+**Update note 2:** [vmalert](https://docs.victoriametrics.com/vmalert.html) by default alert's source now contains a link to vmalert's UI instead of JSON representation. To switch to the old behavior set `-external.alert.source=vmalert/api/v1/alert?group_id={{.GroupID}}&alert_id={{.AlertID}}`.
 
 * SECURITY: [vmalert](https://docs.victoriametrics.com/vmalert.html): do not expose `-remoteWrite.url`, `-remoteRead.url` and `-datasource.url` command-line flag values in logs and at `http://vmalert:8880/flags` page by default, since they may contain sensitive data such as auth keys. This aligns `vmalert` behaviour with [vmagent](https://docs.victoriametrics.com/vmagent.html), which doesn't expose `-remoteWrite.url` command-line flag value in logs and at `http://vmagent:8429/flags` page by default. Specify `-remoteWrite.showURL`, `-remoteRead.showURL` and `-datasource.showURL` command-line flags for showing values for the corresponding `-*.url` flags in logs.

 * FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): add a legend in the top right corner for shortcut keys. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2813).
 * FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): add `toTime()` template function in the same way as Prometheus 2.38 [does](https://github.com/prometheus/prometheus/pull/10993). See [these docs](https://prometheus.io/docs/prometheus/latest/configuration/template_reference/#numbers).
 * FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): add `$alertID` and `$groupID` template variables. These variables may be used for templating annotations or `-external.alert.source` command-line flag. See the full list of supported variables [here](https://docs.victoriametrics.com/vmalert.html#templating).

 * BUGFIX: prevent from excess CPU usage when the storage enters [read-only mode](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#readonly-mode).
 * BUGFIX: improve performance for requests to [/api/v1/labels](https://docs.victoriametrics.com/url-examples.html#apiv1labels) and [/api/v1/label/.../values](https://docs.victoriametrics.com/url-examples.html#apiv1labelvalues) when the filter in the `match[]` query arg matches small number of time series. The performance for this case has been reduced in [v1.78.0](https://docs.victoriametrics.com/CHANGELOG.html#v1780). See [this](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2978) and [this](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1533) issues.
