@ -35,6 +35,7 @@ The following tip changes can be tested by building VictoriaMetrics components f
* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): show `median` instead of `avg` in graph tooltip and line legend, since `median` is more tolerant against spikes. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3706).
* FEATURE: allow setting zero value for `-search.latencyOffset` command-line flag. This may be needed in [some cases](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2061#issuecomment-1299109836). Previously the minimum supported value for `-search.latencyOffset` command-line flag was `1s`.
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): immediately cancel in-flight scrape requests during configuration reload when [stream parsing mode](https://docs.victoriametrics.com/vmagent.html#stream-parsing-mode) is disabled. Previously `vmagent` could wait for long time until all the in-flight requests are completed before reloading the configuration. This could significantly slow down configuration reload. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3747).
* BUGFIX: prevent from possible data ingestion slowdown and query performance slowdown during [background merges of big parts](https://docs.victoriametrics.com/#storage) on systems with small number of CPU cores (1 or 2 CPU cores). The issue has been introduced in [v1.85.0](https://docs.victoriametrics.com/CHANGELOG.html#v1850) when implementing [this feature](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3337). See also [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3790).
* BUGFIX: properly parse timestamps in milliseconds when [ingesting data via OpenTSDB telnet put protocol](https://docs.victoriametrics.com/#sending-data-via-telnet-put-protocol). Previously timestamps in milliseconds were mistakenly multiplied by 1000. Thanks to @Droxenator for the [pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3810).
