@ -25,6 +25,7 @@ The following tip changes can be tested by building VictoriaMetrics components f
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): add `__meta_kubernetes_endpoints_name` label for all ports discovered from endpoint. Previously, ports not matched by `Service` did not have this label. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4154) for details. Thanks to @thunderbird86 for discovering and [fixing](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/4253) the issue.
* BUGFIX: fix possible infinite loop during `indexdb` rotation when `-retentionTimezoneOffset` command-line flag is set and the local timezone is not UTC. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4207). Thanks to @faceair for [the fix](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/4206).
* BUGFIX: [alerts-health](https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/deployment/docker/alerts-health.yml): update threshold for `TooHighMemoryUsage` alert from 90% to 80%, since 90% is too high for production environments.
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): properly handle the `vm_promscrape_config_last_reload_successful` metric after config reload. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4260).
* BUGFIX: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation.html): suppress `series after dedup` error message in logs when `-remoteWrite.streamAggr.dedupInterval` command-line flag is set at [vmagent](https://docs.victoriametrics.com/vmgent.html) or when `-streamAggr.dedupInterval` command-line flag is set at [single-node VictoriaMetrics](https://docs.victoriametrics.com/).
