 * FEATURE: add ability to accept metrics from [DataDog agent](https://docs.datadoghq.com/agent/) and [DogStatsD](https://docs.datadoghq.com/developers/dogstatsd/). See [these docs](https://docs.victoriametrics.com/Single-server-VictoriaMetrics.html#how-to-send-data-from-datadog-agent). This option simplifies the migration path from DataDog to VictoriaMetrics. See also [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/206).
 * FEATURE: vmagent [enterprise](https://victoriametrics.com/enterprise.html): add support for data reading and writing from/to [Apache Kafka](https://kafka.apache.org/). See [these docs](https://docs.victoriametrics.com/vmagent.html#kafka-integration).
+* FEATURE: vmui: switch to [μPlot](https://github.com/leeoniya/uPlot) and add ability to naturally scroll and zoom graphs. See [these docs](https://docs.victoriametrics.com/#vmui). Thanks to @Loori-R.
 * FEATURE: vmstorage: stop accepting new data if `-storageDataPath` directory contains less than `-storage.minFreeDiskSpaceBytes` of free space. This should prevent from `out of disk space` crashes. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/269).
 * FEATURE: calculate quantiles in the same way as Prometheus does in such functions as [quantile_over_time](https://docs.victoriametrics.com/MetricsQL.html#quantile_over_time) and [quantile](https://docs.victoriametrics.com/MetricsQL.html#quantile). Previously results from VictoriaMetrics could be slightly different than results from Prometheus. See [this](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1625) and [this](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1612) issues.
 * FEATURE: add `rollup_scrape_interval(m[d])` function to [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html), which returns `min`, `max` and `avg` values for the interval between samples for `m` on the given lookbehind window `d`.
 * FEATURE: add `topk_last(k, q)` and `bottomk_last(k, q)` functions to [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html), which return up to `k` time series from `q` with the maximum / minimum last value on the graph.
-* FEATURE: vmui: add ability to naturally scroll and zoom graphs. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1634).
 
 * BUGFIX: align behavior of the queries `a or on (labels) b`, `a and on (labels) b` and `a unless on (labels) b` where `b` has multiple time series with the given `labels` to Prometheus behavior. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1643).
 * BUGFIX: vmagent: fix `openstack_sd_config` service discovery when both `domain_name` and `project_id` config options are set. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1655).

+VictoriaMetrics provides UI for query troubleshooting and exploration. The UI is available at `http://victoriametrics:8428/vmui`.
+The UI allows exploring query results via graphs and tables. Graphs support scrolling and zooming:
+
+* Drag the graph to the left / right in order to move the displayed time range into the past / future.
+* Hold `Ctrl` (or `Cmd` on MacOS) and scroll up / down in order to zoom in / out the graph.
