RECOMMENDED

Overall status: RECOMMENDED

Cautions

It's no longer possible or necessary to explicitly set proxy-init's resource requests or limits; see the Changes section for more information.

Changes

This release changes the proxy-init container to always request the same amount of memory and CPU as the proxy itself, and removes the ability to explicitly set proxy-init's requests because there's now no need to do so. (This doesn't increase the resources required for the pod as a whole, because the proxy-init container completes before the proxy starts, letting the proxy reuse resources requested by the proxy-init container.) It also continues work on upcoming GRPCRoute support. Finally, if proxy.logHTTPHeaders is somehow empty, it correctly defaults to "off".

RECOMMENDED

Overall status: RECOMMENDED

Cautions

This release includes one breaking change: the proxy's /shutdown endpoint is now disabled by default. See Changes for how to reenable it.

Changes

This release disables the proxy's /shutdown endpoint by default; it can be reenabled by using --set proxy.enableShutdownEndpoint=true when installing or upgrading. Beyond that, it fixes several bugs: EndpointSlices with no hostname field are supported (thanks, Adrian Callejas!), DNS resolution errors are correctly logged (and the resolver's log level can be configured), the proxy's administration endpoints function correctly on systems using IPv4-mapped IPv6, and the init container and CNI plugin will not attempt to start on systems that configure IPv6 but don't support ip6tables. Finally, it supports controlling whether or not HTTP headers are logged in debug output (with the default being "not"), JSON output for the link, unlink, allow, and allow-scrapes CLI commands, and fixes a typo in the output of linkerd diagnostics (thanks, John Howard!)

RECOMMENDED

Overall status: RECOMMENDED

Cautions

In this release, IPv6 is off by default for the entire control plane. To use IPv6, you'll need to explicitly set it -- see the Changes section below.

Changes

This release switches IPv6 off by default for the entire control plane, including the Linkerd CNI plugin. Set disableIPv6 to false to enable IPv6.

NOT RECOMMENDED

Overall status: NOT RECOMMENDED; use edge-24.5.5 instead

Cautions

In this release, IPv6 support is off by default for most of the control plane, but it is mistakenly on by default in the Linkerd CNI plugin. We recommend using edge-24.5.5 instead, which has the fix for that error.

Changes

This release adds support for JSON output to the linkerd inject, linkerd uninject and linkerd profile commands, and a --token flag to linkerd diagnostics policy that allows specifying the context token to use so that you can see how specific clients will see policies. It also adds support for setting the group ID for the control plane (thanks, Nico Feulner!), switches IPv6 to off by default for the control plane, adds support for several proxy settings to the linkerd-control-plane chart, allows overriding how many cores control-plane components can use, correctly supports Gateway API producer routes, fixes a race conditions around EndpointSlice updates, and fixes intermittent routing failures with HTTPRoute (issue 12610).

RECOMMENDED

Overall status: RECOMMENDED, but see Cautions

Cautions

If you use the Linkerd CNI plugin on GKE, you will need to disable IPv6 or use edge-24.5.5 instead.

Changes

This release removes an internal limit on the number of concurrent gRPC streams to the control plane, leaving available memory as the only constraint.

RECOMMENDED

Overall status: RECOMMENDED, but see Cautions

Cautions

If you use the Linkerd CNI plugin on GKE, you will need to explicitly disable IPv6 or use edge-24.5.5 instead.

If you don't use set enableHttpRoutes to false when installing this release, it will install the grpcroute.gateway.networking.k8s.io CRD into your cluster and remove it when Linkerd is uninstalled.

Changes

This release adds support for IPv6. It defaults to enabled: set disableIPv6 to true when installing to disable it. It also correctly sets the backend_not_found status on HTTPRoutes with no backends. Finally, it adds the Gateway API GRPCRoute resource as part of continued work on support for GRPCRoutes, although this edge release doesn't attach any functionality to the CRD.
