## tip
* FEATURE: vmauth: add ability to set madatory query args in `url_prefix`. For example, `url_prefix: http://vm:8428/?extra_label=team=dev` would add `extra_label=team=dev` query arg to all the incoming requests. See [the example](https://docs.victoriametrics.com/vmauth.html#auth-config) for more details.
* FEATURE: add OpenTSDB migration option to vmctl. See more details [here](https://docs.victoriametrics.com/vmctl#migrating-data-from-opentsdb).
Thanks to @johnseekins!
* FEATURE: improved new time series registration speed on systems with many CPU cores. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1244). Thanks to @waldoweng for the idea and [draft implementation](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1243).
* FEATURE: vmagent: list user-visible endpoints at `http://vmagent:8429/`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1251).
* FEATURE: vmalert: use the same technique as Grafana for determining evaluation timestamps for recording rules. This should make consistent graphs for series generated by recording rules compared to graphs generated for queries from recording rules in Grafana. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1232).
* FEATURE: log metrics with dropped labels if the number of labels in the ingested metric exceeds `-maxLabelsPerTimeseries`. This should simplify debugging for this case.
* BUGFIX: vmagent: properly update `role: endpoints` and `role: endpointslices` scrape targets if the underlying service changes in `kubernetes_sd_config`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1240).

* BUGFIX: vmagent: properly update `role: endpoints` and `role: endpointslices` scrape targets if the underlying service objects are updated in `kubernetes_sd_config`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1240).
* BUGFIX: vmagent: apply `scrape_timeout` on receiving the first response byte from `stream_parse: true` scrape targets. Previously it was applied to receiving and *processing* the full response stream. This could result in false timeout errors when scrape target exposes millions of metrics as described [here](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1017#issuecomment-767235047).
* BUGFIX: vmagent: eliminate possible data race when obtaining value for the metric `vm_persistentqueue_bytes_pending`. The data race could result in incorrect value for this metric.
* BUGFIX: vmstorage: remove empty directories on startup. Such directories can be left after unclean shutdown on NFS storage. Previously such directories could lead to crashloop until manually removed. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1142).
