 **Update note 1: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): perform deduplication for all received data when specifying `-streamAggr.dedupInterval` or `-remoteWrite.streamAggr.dedupInterval` command-line flag. Previously, if the `-remoteWrite.streamAggr.config` or `-streamAggr.config` is set, only series that matched aggregation config were deduplicated. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6711#issuecomment-2288361213) for details.**
 
+**Update note 2: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): default value of `-loggerMaxArgLen` cmd-line flag was increased from 1000 to 5000. This should improve visibility on errors produced by very long queries.**

 * SECURITY: upgrade Go builder from Go1.23.0 to Go1.23.1. See the list of issues addressed in [Go1.23.1](https://github.com/golang/go/issues?q=milestone%3AGo1.23.1+label%3ACherryPickApproved).
 * SECURITY: upgrade base docker image (Alpine) from 3.20.2 to 3.20.3. See [alpine 3.20.3 release notes](https://alpinelinux.org/posts/Alpine-3.17.10-3.18.9-3.19.4-3.20.3-released.html).

 * BUGFIX: [Single-node VictoriaMetrics](https://docs.victoriametrics.com/) and `vmstorage` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/cluster-victoriametrics/): properly track `vm_missing_tsids_for_metric_id_total` metric. See this [issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6931) for details.
 * BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert): do not send notifications without labels to Alertmanager. Such notifications are rejected by Alertmanager anyway. Before, vmalert could send alert notifications even if no label-value pairs left after applying `alert_relabel_configs` from [notifier config](https://docs.victoriametrics.com/vmalert/#notifier-configuration-file).
 * BUGFIX: [MetricsQL](https://docs.victoriametrics.com/metricsql/): properly handle `c1 AND c2` and `c1 OR c1` queries for constants `c1` and `c2`. Previously such queries could return unexpected results. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6637).
+* BUGFIX: all VictoriaMetrics components: increase default value of `-loggerMaxArgLen` cmd-line flag from 1000 to 5000. This should improve visibility on errors produced by very long queries.
