## tip
* FEATURE: [VictoriaMetrics cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html): add `http://<vmselect>:8481/admin/tenants` API endpoint for returning a list of registered tenants. See [these docs](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#url-format) for details.
* FEATURE: [VictoriaMetrics enterprise](https://docs.victoriametrics.com/enterprise.html): add `-storageNode.filter` command-line flag for filtering the [discovered vmstorage nodes](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#automatic-vmstorage-discovery) with arbitrary regular expressions. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3353).
* FEATURE: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): allow using numeric values with `K`, `Ki`, `M`, `Mi`, `G`, `Gi`, `T` and `Ti` suffixes inside MetricsQL queries. For example `8Ki` equals to `8*1024`, while `8.2M` equals to `8.2*1000*1000`.
* FEATURE: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): add [range_normalize](https://docs.victoriametrics.com/MetricsQL.html#range_normalize) function for normalizing multiple time series into `[0...1]` value range. This function is useful for correlation analysis of time series with distinct value ranges. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3167).

Note that the `delete_series` handler should be used only in exceptional cases such as deletion of accidentally ingested incorrect time series. It shouldn't
be used on a regular basis, since it carries non-zero overhead.
- URL for listing [tenants](#multitenancy) with the ingested data on the given time range: `http://<vmselect>:8481/admin/tenants?start=...&end=...` .
The `start` and `end` query args are optional. If they are missing, then all the tenants with at least one sample stored in VictoriaMetrics are returned.
- URL for accessing [vmalert's](https://docs.victoriametrics.com/vmalert.html) UI: `http://<vmselect>:8481/select/<accountID>/prometheus/vmalert/`.
This URL works only when `-vmalert.proxyURL` flag is set. See more about vmalert [here](#vmalert).
