* SECURITY: upgrade Go builder from Go1.20.4 to Go1.21.0.
* SECURITY: upgrade base docker image (Alpine) from 3.18.2 to 3.18.3. See [alpine 3.18.3 release notes](https://alpinelinux.org/posts/Alpine-3.15.10-3.16.7-3.17.5-3.18.3-released.html).
* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert.html): reset evaluation timestamp after modifying group interval. Before, there could have latency on rule evaluation time.
* BUGFIX: vmselect: fix timestamp alignment for Prometheus querying API if time argument is less than 10m from the beginning of Unix epoch.
* BUGFIX: vminsert: fixed decoding of label values with slash when accepting data via [pushgateway protocol](https://docs.victoriametrics.com/#how-to-import-data-in-prometheus-exposition-format). This fixes Prometheus golang client compatibility. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4692).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): close HTTP connections to [service discovery](https://docs.victoriametrics.com/sd_configs.html) servers when they are no longer needed. This should prevent from possible connection exhasution in some cases. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4724).
