We’ve upgraded all Teleport clusters from version 13.3.0 to 13.3.8. Teleport is a tool we mostly use internally to provide secure and auditted access to (EC2) instances, Kubernetes clusters and several dashboards. The nodes will gradually be upgraded to the new version when new instances are launched.
These upgrades mostly bring security and bug fixes. You can find more information on this release in the Teleport changelog.
