# Linkerd edge-26.9.1

> Networking & Messaging · 2026-09-04

A maintenance release updates the proxy and dependencies, fixes destination behavior, and tightens multicluster credential and `Link` resource handling. The changes concern proxy, destination, and multicluster components, alongside routine dependency updates.

## Action needed
- **[breaking]** Cluster credential secrets and the `exec` auth provider
  - Cluster credential secrets created by `linkerd multicluster link` use the token auth provider. The `exec` auth provider is disallowed because it is not used or necessary.
- **[breaking]** `Link` resource lookup scope
  - `Link` resource lookups are restricted to the `linkerd-multicluster` namespace.

## Other recorded changes
- 17 (value_changed 16, defect_corrected 1)
