N/A

Changes

This release fixes an error in the CLI in order to allow the linkerd multicluster CLI commands to work correctly even when some of the clusters in a multicluster setup are running releases prior to edge-24.9.3. Additionally, creating a link with linkerd multicluster link --set enableNamespaceCreation=true will allow Linkerd multicluster to create the namespace into which it mirrors services.

RECOMMENDED

Overall status: RECOMMENDED

Cautions

If you're using Linkerd multicluster with clusters running edge-24.9.2 or earlier, you'll need to upgrade your Linkerd CLI to at least edge-24.10.2 for the linkerd multicluster commands to work correctly.

Changes

This release supports native OpenTelemetry tracing: use --set webhook.collectorTraceProtocol=opentelemetry to use it. The default is still opencensus for the OpenCensus wire protocol. Additionally, the proxy addresses issue #13023 by setting a 30-second TCP_USER_TIMEOUT on TCP connections to allow Linkerd to do a better job of cleaning up half-open connections (thanks, Vadim Makerov!)

Changes

edge-24.9.3 fixes a panic that would occur if a retried response arrived before the retried request was complete. This is allowed by the spec and was seen in the field with retries enabled for wire-grpc. Additionally, it supports configuring the timeout and failure threshold for health probes for the multicluster gateway.

RECOMMENDED

Overall status: RECOMMENDED

Cautions

Starting in edge-24.9.2, the timestamp in JSON-formatted proxy logs are now ISO8601 strings, for example

{"timestamp":"2024-09-09T13:38:56.919918Z","level":"INFO","fields":{"message":"Using single-threaded proxy runtime"},"target":"linkerd2_proxy::rt","threadId":"ThreadId(1)"}

Changes

This release allows Linkerd Viz to get Prometheus basic-auth credentials from a Secret (set prometheusCredsSecret when installing Viz), switches the proxy to use ISO8601 timestamps when logging JSON (fixing issue 12505), publishes a variety of new internal metrics about how the proxy runtime is performing, and publishes the proxy's current time as a metric to make it easier to know when certificates need to be rotated. It also allows setting TCP_USER_TIMEOUT for TCP sockets (thanks, Vadim Makerov!), updates the Helm documentation to include recently-added values, and removes some redundant dashes in the identity controller's Helm templates. Finally, it also includes the org.opencontainers.image.source label in all the Linkerd Docker images (thanks, Maxime Brunet!).

Changes

This release adds the new linkerd viz stat-inbound and linkerd viz stat-outbound commands to easily examine statistics for Gateway API routes, and adds dualstack support for ExternalWorkload. It also adds Helm support for tuning liveness and readiness probe timeouts (thanks @kristjankullerkann-wearemp!) and configuring externalTrafficPolicy for multicluster gateways (thanks Lauri Kuittinen!).

Changes

In addition to dependency upgrades, this edge release has two fixes for Linkerd Viz: it correctly supports setting the group ID using the linkerd-viz Helm chart (thanks, @mozemke!) and it cleans up font downloading to avoid WAF errors.

Changes

This release makes certain that Linkerd won't attempt to bind to IPv6 addresses at all unless IPv6 is enabled.

What's Changed

  • build(deps): bump actions/upload-artifact from 4.3.4 to 4.3.5 by @dependabot in #12937
  • Only bind to IPv6 addresses when disableIPv6=false by @alpeb in #12938

RECOMMENDED

Overall status: RECOMMENDED

Cautions

If you don't have the GRPCRoute CRD installed at all, Linkerd will run without GRPCRoute support. If you add the CRD after starting Linkerd, you'll need to restart the control plane for Linkerd to be able to use GRPCRoutes.

Changes

This release makes GRPCRoute optional: if you don't have the GRPCRoute CRD installed, Linkerd will run without any GRPCRoute functionality rather than failing to start. It also improves the status text when an HTTPRoute is incorrectly configured with parentRef pointing to a headless service, to make this situation easier to debug, and makes certain that trace-level logs honor proxy.logHTTPHeaders.
