* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): add support for specifying Basic Auth password for notifiers via a file. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1567).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): provide the ability to fetch target responses on behalf of `vmagent` by clicking the `response` link for the needed target at `/targets` page. This feature may be useful for debugging responses from targets located in isolated environments.
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): show the total number of scrapes and the total number of scrape errors per target at `/targets` page. This information may be useful when debugging unreliable scrape targets.
* FEATURE: vmagent and single-node VictoriaMetrics: disallow unknown fields at `-promscrape.config` file. Previously unknown fields were allowed. This could lead to long-living silent config errors. The previous behaviour can be returned by passing `-promscrape.config.strictParse=false` command-line flag.
* BUGFIX: return proper results from `highestMax()` function at [Graphite render API](https://docs.victoriametrics.com/#graphite-render-api-usage). Previously it was incorrectly returning timeseries with min peaks instead of max peaks.
* BUGFIX: properly limit indexdb cache sizes. Previously they could exceed values set via `-memory.allowedPercent` and/or `-memory.allowedBytes` when `indexdb` contained many data parts. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2007).
