Overall status: RECOMMENDED
Cautions
This release requires that the Kubernetes API server be able to use TLS v1.3. That's been supported since Kubernetes v1.19, and Linkerd currently requires at least Kubernetes v1.22, so this shouldn't be an issue for anyone. It also validates that proxy.runAsRoot be set if proxyInit.closeWaitTimeoutSecs is set -- this was a functional requirement anyway, but we now validate it at install time.
Changes
Welcome to 2025! This first release of the year bumps the minimum TLS version when talking to the API server to v1.3 (see the CAUTIONS above), adds proper iptables support for RHEL nodes, allows Linkerd to talk to running Pods which haven't passed readiness checks yet (thanks, Tuomo!), and allows specifying both podAnnotations per deployment (thanks, Takumi Sue!) and labels for the Viz dashboard (thanks, omer2500!). It also validates that proxy.runAsRoot is set if you try to set proxyInit.closeWaitTimeoutSecs, correctly handles proxy log levels with quotes, cleans up CLI output of port forwarding errors, adds the pod UID and proxy container name to the environment, fixes a bug with installing extensions with Helm in IPv6 clusters, and removes some unneeded CNI configuration values. Finally, thanks to Joakim Roubert for cleaning up some development shell scripting!
