Changes
This release correctly discovers ports and port opacity when using native sidecars, and fixes a race condition in the CNI plugin that could prevent proper deployment in some environments, particularly EKS.

Overall status: RECOMMENDED
Cautions
As of this release, the
proxy-initimage has been merged into theproxyimage, which simplifies image management and reduces overall image size. Users who were explicitly using theproxy-initimage should use theproxyimage in its place.Changes
This release correctly honors the
timeouts.requestvalue of HTTPRoutes in thegateway.networking.k8s.ioAPI group, to match the behavior ofpolicy.linkerd.ioHTTPRoutes.What's Changed

Overall status: NOT RECOMMENDED, use edge-25.11.3 instead
Cautions
In this release, mesh expansion does not correctly get certificates from SPIRE; we recommend using edge-25.11.3 instead.
Changes
This release fixes broken documentation URLs in CLI commands (thanks, beza!) and corrects a typo in the EgressNetwork and ExternalWorkload CRD definitions (thanks, YY!).

N/A
Changes
This release correctly includes pod metadata in OpenTelemetry traces, fixes the
workload_subscribersmetric to correctly track the total number of subscribers across all IP and port combinations (rather than only the most recent combination), and prevents a task leak when using federated services.What's Changed

This release prevents a possible crash when injecting proxies without tracing configured, and includes semantic convention labels
user-agent.original,http.request.header.content-length,http.request.header.content-type, andhttp.request.header.l5d-orig-prototo OpenTelemetry spans.What's Changed

vedge-25.10.3Compare Source
Overall status: NOT RECOMMENDED, use edge-25.10.7 instead
Cautions
This release includes one breaking change: it removes the
ip_port_subscribersmetric and replaces it with the lower-cardinalityworkload_subscribersmetric.Changes
This release removes the
linkerd.io/proxy-root-parentandlinkerd.io/proxy-root-parent-kindlabels added to injected pods in edge-25.10.2. It also fixes a potential deadlock that could result in leaked tasks and unneeded memory consumption, and allows configuring the destination controller's stream queue capacity. The default remains 100 for the moment; lower values may be better for improving responsiveness to readiness and liveness issues.What's Changed
Full Changelog: linkerd/linkerd2@edge-25.10.2...edge-25.10.3
vedge-25.10.2Compare Source
Overall status: NOT RECOMMENDED, use edge-25.10.7 instead
Cautions
This release drops support for the (long-deprecated) OpenCensus trace protocol. Additionally, it adds the
linkerd.io/proxy-root-parentandlinkerd.io/proxy-root-parent-kindlabels to injected pods, but this change was reverted in edge-25.10.3 due to unforeseen issues.Changes
This release adds support for setting OpenTelemetry tracing values via
resource.opentelemetry.io/<label>annotations on pods, making it simpler to customize tracing for specific workloads. Additionally, it moves native sidecar support to beta, adding theconfig.beta.linkerd.io/proxy-enable-native-sidecarannotation and deprecating the alpha annotation (although that will continue to function).What's Changed

vedge-25.10.1Compare Source
Overall status: RECOMMENDED
Cautions
This release drops support for the Linkerd Jaeger extension: instead, it supports directly configuring OpenTelemetry tracing by setting
controller.tracing.enableandcontroller.tracing.collector.endpointwhen installing Linkerd.Changes
This release guarantees that OpenTelemetry spans are flushed regularly, and not just when streams become idle. It also adds the
inbound_http_request_frame_size_bytesandinbound_grpc_request_frame_size_byteshistograms to metrics, to allow better visibility into request body sizes.What's Changed

vedge-25.9.4Compare Source
Overall status: RECOMMENDED
Cautions
Starting in this release, the
linkerd-crdsHelm chart will no longer install the Gateway API CRDs by default. To force the chart to install the Gateway API CRDs, setinstallGatewayAPI=truewhen installing the chart.If you previously used the
linkerd-crdschart to install the Gateway API CRDs, and you're running Linkerd 2.18/edge-25.4.4 or higher, upgrading with Helm will not uninstall the Gateway API CRDs. If you're upgrading from an earlier version, you will need to install the Gateway API CRDs manually.Changes
This release fixes an issue where native sidecar proxies could have stale endpoint data, resulting in problems routing traffic. Additionally, it correctly supports ReplacePrefixMatch in HTTPRoute RequestRedirect filters.
