 ## v1.87.x long-time support release (LTS)
 
 * SECURITY: upgrade base docker image (alpine) from 3.17.2 to 3.17.3. See [alpine 3.17.3 release notes](https://alpinelinux.org/posts/Alpine-3.17.3-released.html).
+* SECURITY: upgrade Go builder from Go1.20.2 to Go1.20.3. See [the list of issues addressed in Go1.20.3](https://github.com/golang/go/issues?q=milestone%3AGo1.20.3+label%3ACherryPickApproved).
 
 * BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly convert [VictoriaMetrics historgram buckets](https://valyala.medium.com/improving-histogram-usability-for-prometheus-and-grafana-bc7e5df0e350) to Prometheus histogram buckets when VictoriaMetrics histogram contain zero buckets. Previously these buckets were ignored, and this could lead to missing Prometheus histogram buckets after the conversion. Thanks to @zklapow for [the fix](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/4021).
 * BUGFIX: [vmagent](https://docs.victoriametrics.com/vmgent.html): fix CPU and memory usage spikes when files pointed by [file_sd_config](https://docs.victoriametrics.com/sd_configs.html#file_sd_configs) cannot be re-read. See [this_issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3989).
