 ## tip
 
+* SECURITY: upgrade Go builder from Go1.20.3 to Go1.20.4. See [the list of issues addressed in Go1.20.4](https://github.com/golang/go/issues?q=milestone%3AGo1.20.4+label%3ACherryPickApproved).
 * SECURITY: serve `/robots.txt` content to disallow indexing of the exposed instances by search engines. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4128) for details.
 
 * FEATURE: [vmbackup](https://docs.victoriametrics.com/vmbackup.html): store backup creation and completion time in `backup_complete.ignore` file of backup contents. This is useful to determine point in time when backup was created and completed.
