Changes

edge-24.11.3 brings local rate limiting to Linkerd! Using the new HTTPLocalRateLimitPolicy resource, you can attach rate limits to Servers to protect workloads from being overwhelmed by excessive traffic. Additionally, it improves metrics for TCPRoute and TLSRoute egress control, correctly handles the case where a Route type changes parents (fixing [issue #13280]), allows linkerd diagnostics endpoints to correctly handle workloads with multiple endpoints, and removes unneeded references to linkerd-base from the linkerd-control-plane chart README (thanks, Brandon Ros!).

edge-24.11.2 (November 8, 2024)

NOT RECOMMENDED

Overall status: NOT RECOMMENDED, use edge-24.11.3 instead

Cautions

linkerd diagnostics endpoints may not correctly show all endpoints for federated Services. We recommend using edge-24.11.3 instead, which fixes this issue.

Changes

edge-24.11.2 brings federated Services to Linkerd multicluster setups! Every federated Service appears exactly the same from every cluster (rather than having names like svc-cluster) and Linkerd seamlessly handles everything to gather the relevant endpoints from all clusters, without requiring application changes or HTTPRoute configuration.

Changes

edge-24.11.1 brings egress monitoring and control to Linkerd! Using the new EgressNetwork CRD as a parentRef for an HTTPRoute, GRPCRoute, TCPRoute, or TLSRoute, you can see which workloads are making egress calls and set policy on what's allowed and what isn't.

RECOMMENDED

Overall status: RECOMMENDED

Cautions

As of edge-24.10.5, if you configure a timeout on a GRPCRoute, a request that hits the timeout will correctly return a DEADLINE-EXCEEDED gRPC status rather than an UNAVAILABLE gRPC status.

Changes

edge-24.10.5 fixes a bug where requests that hit GRPCRoute timeouts would return gRPC status UNAVAILABLE instead of DEADLINE-EXCEEDED.

Changes

edge-24.10.3 adds hostname and zone_locality labels for outbound GRPC and HTTP metrics, providing the hostname and zone used for the target. It also allows configuring the service name for Linkerd's distributed traces (fixing #11157) and fixes a bug where the linkerd-jaeger injector could mistakenly alter annotations it shouldn't have, as well as a bug where the CNI plugin would silently fail if the underlying Node hit the inotify limit -- now it will detect the problem and crash so that the problem can be noticed and corrected. Finally, linkerd multicluster link now produces YAML that can be applied into clusters running versions prior to edge-24.9.3.

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.
