@ -53,6 +53,7 @@ The sandbox cluster installation is running under the constant load generated by
* FEATURE: [vmctl](https://docs.victoriametrics.com/vmctl.html): rename cmd-line flag `vm-native-disable-retries` to `vm-native-disable-per-metric-migration` to better reflect its meaning.
* FEATURE: [vmctl](https://docs.victoriametrics.com/vmctl.html): add `-vm-native-src-insecure-skip-verify` and `-vm-native-dst-insecure-skip-verify` command-line flags for native protocol. It can be used for skipping TLS certificate verification when connecting to the source or destination addresses.
* FEATURE: [Alerting rules for VictoriaMetrics](https://github.com/VictoriaMetrics/VictoriaMetrics/tree/master/deployment/docker#alerts): add `job` label to `DiskRunsOutOfSpace` alerting rule, so it is easier to understand to which installation the triggered instance belongs.
* FEATURE: `vmstorage`: add tenant identifier for log messages regarding dropping excessive labels due to limits defined by `-maxLabelsPerTimeseries` or `-maxLabelValueLen` command-line flags. Previously, it was hard to understand to which tenant the dropped labels belong.
* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): add the ability to export and import query reports:
- add a `Query Analyzer` page that allows you to build graphs from `JSON` data containing the results of executing a query request.
- add an `Export query` button to the graph that saves the result of executing the query in `JSON`. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5497).
