 * FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): add [increase_prometheus](https://docs.victoriametrics.com/stream-aggregation/#increase_prometheus) and [total_prometheus](https://docs.victoriametrics.com/stream-aggregation/#total_prometheus) outputs, which can be used for `increase` and `total` aggregations when the first sample of every new [time series](https://docs.victoriametrics.com/keyconcepts/#time-series) must be ignored.
 * FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): expose `vm_streamaggr_flush_timeouts_total` and `vm_streamaggr_dedup_flush_timeouts_total` [counters](https://docs.victoriametrics.com/keyconcepts/#counter) at [`/metrics` page](https://docs.victoriametrics.com/#monitoring), which can be used for detecting flush timeouts for stream aggregation states. Expose also `vm_streamaggr_flush_duration_seconds` and `vm_streamaggr_dedup_flush_duration_seconds` [histograms](https://docs.victoriametrics.com/keyconcepts/#histogram) for monitoring the real flush durations of stream aggregation states.
 * FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): improve trace display for better visual separation of branches. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5926).
+* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): use the provided `-remoteWrite.tlsServerName` as `Host` header in requests to `-remoteWrite.url`. This allows sending data to https remote storage by IP address instead of hostname. Thanks to @minor-fixes for initial idea and [the pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5802).
 
 * BUGFIX: do not drop `match[]` filter at [`/api/v1/series`](https://docs.victoriametrics.com/url-examples/#apiv1series) if `-search.ignoreExtraFiltersAtLabelsAPI` command-line flag is set, since this broke the `/api/v1/series` requests.
