 * **Ideal for big data**: Works well with large amounts of time series data from APM, Kubernetes, IoT sensors, connected cars, industrial telemetry, financial data and various [Enterprise workloads](https://docs.victoriametrics.com/victoriametrics/enterprise/).
 * **Query language**: Supports both PromQL and the more performant MetricsQL.
 * **Easy to setup**: No dependencies, single [small binary](https://medium.com/@valyala/stripping-dependency-bloat-in-victoriametrics-docker-image-983fb5912b0d), configuration through command-line flags, but the default is also fine-tuned; backup and restore with [instant snapshots](https://medium.com/@valyala/how-victoriametrics-makes-instant-snapshots-for-multi-terabyte-time-series-data-e1f3fb0e0282).
-* **Global query view**: Multiple Prometheus instances or any other data sources may ingest data into VictoriaMetrics and be queried via a single query.

 **Update Note 1:** `vmselect` and `vminsert` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/), and `vmagent`: default value of `-enableMultitenancyViaHeaders` command-line flag has changed from `false` to `true`. This change enables support of [multitenancy via headers for cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#multitenancy-via-headers) and [for vmagent](https://docs.victoriametrics.com/victoriametrics/vmagent/#multitenancy-via-headers) by default. With this change, mentioned components will start supporting URLs with omitted tenant ID in the path: `https://<vmselect>:8481/select/prometheus/api/v1/query` will become a valid URL. To disable multitenancy via headers and simplified URLs set `--enableMultitenancyViaHeaders=false` on vmagent, vminsert and vmselect.

-* BUGFIX: [vmsingle](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/) and `vmselect` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/): change the HTTP response code for [Prometheus querying API](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#prometheus-querying-api-usage) requests from `422 Unprocessable Entity` to `400 Bad Request` when request parameters are missing or incorrect. See [#11330](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/11330).
-* BUGFIX: [vmsingle](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/) and `vminsert` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/): skip labels with empty name at [/api/v1/import](https://docs.victoriametrics.com/victoriametrics/#how-to-import-data-in-json-line-format). Previously such a label replaced the metric name, so a series sent with `"metric":{"__name__":"foo","":"bar"}` was stored under the name `bar`. Other ingestion protocols already skip such labels. See [#4962](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4962).
-* BUGFIX: [vmalert](https://docs.victoriametrics.com/victoriametrics/vmalert/): properly update group-level `eval_delay` and `eval_alignment` for existing groups during runtime when config reload is triggered periodically or manually via `/-/reload`. Previously, these settings weren't updated after config reload during runtime. See [#11374](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/11374).
-* BUGFIX: `vmselect` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/): scale the default `-search.maxConcurrentRequests` with the number of available CPU cores instead of capping it at 16. See [#11191](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/11191). Thanks to @Dhru1Tanna for contribution.
