We’ve upgraded all Teleport clusters to 15.4.21. 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. You can find more information on this release in the Teleport changelog.
Headsup: This will most likely be the last upgrade of Teleport. Due to the license change in v16 we will replace Teleport with Tailscale an easy way for us to connect to our customer environments in a secure way. We will provide more information on this in the coming weeks.
