 * BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): fix for `showLegend` and `alias` flags in predefined panels. [See this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7565)
 * BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert): improve the correctness of alert [state restoration](https://docs.victoriametrics.com/vmalert/#alerts-state-on-restarts). Previously, it could result in false-positive alerts if alert was resolved shortly before vmalert restart.
 * BUGFIX: [vmalert-tool](https://docs.victoriametrics.com/vmalert-tool/): exit immediately with error message if no test file is found under specified `-files`.
+* BUGFIX: [vmalert-tool](https://docs.victoriametrics.com/vmalert-tool/): print an error message if no rule group is found in `rule_files`.
 * BUGFIX: `vmselect` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/cluster-victoriametrics/): Properly handle [multitenant](https://docs.victoriametrics.com/cluster-victoriametrics/#multitenancy-via-labels) query request errors and correctly perform search for available tenants. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7549) for details. This is follow-up after [v1.106.1](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.106.1) release changes.
 * BUGFIX: `vmselect` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/cluster-victoriametrics/): properly set `multitenant` cache expiration duration with `search.tenantCacheExpireDuration`. Previously flag always used default value.
