 ## tip
 
+
+## [v1.84.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.84.0)
+
+Released at 25-11-2022
+
+* FEATURE: add support for [Pushgateway data import format](https://github.com/prometheus/pushgateway#url) via `/api/v1/import/prometheus` url. See [these docs](https://docs.victoriametrics.com/#how-to-import-data-in-prometheus-exposition-format) and [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1415). Thanks to @PerGon for [the intial implementation](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3360).
+* 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).
 * FEATURE: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): add [range_linear_regression](https://docs.victoriametrics.com/MetricsQL.html#range_linear_regression) function for calculating [simple linear regression](https://en.wikipedia.org/wiki/Simple_linear_regression) over the input time series on the selected time range. This function is useful for predictions and capacity planning. For example, `range_linear_regression(process_resident_memory_bytes)` can predict future memory usage based on the past memory usage.
 * FEATURE: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): add [range_stddev](https://docs.victoriametrics.com/MetricsQL.html#range_stddev) and [range_stdvar](https://docs.victoriametrics.com/MetricsQL.html#range_stdvar) functions.
-* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): improve structure project, change state management, reduce bundle size, remove Material-UI. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3298)
+* FEATURE: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): optimize `expr1 op expr2` query when `expr1` returns an empty result. In this case there is no sense in executing `expr2` for `op` not equal to `or`, since the end result will be empty according to [PromQL series matching rules](https://prometheus.io/docs/prometheus/latest/querying/operators/#vector-matching). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3349). Thanks to @jianglinjian for pointing to this case.
+* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): add the ability to upload/paste JSON to investigate the trace. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3308) and [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3310).
+* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): reduce JS bundle size from 200Kb to 100Kb. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3298).
+* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): add the ability to hide results of a particular query by clicking the `eye` icon. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3359).
+* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): add copy button to row on Table view. The button copies row in MetricQL format. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2815).
+* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): add compact table view. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3241).
+* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): add the ability to "stick" a tooltip on the chart by clicking on a data point. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3321) and [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3376)
