Its shipped artifacts are Helm charts, Go modules, a Rust crate of the proxy gRPC bindings, and CLI installers. Only the Buoyant-operated Helm repo (helm.buoyant.cloud) and the Linkerd edge channel are actively released; the open-source stable Helm channel and the Homebrew tap have not moved since 2024 and 2023 respectively, which is recorded below as a currency finding rather than a defect in the enterprise product. packages: - name: linkerd-enterprise-control-plane registry: helm registry_url: https://helm.buoyant.cloud official: true language: helm version: 2.20.2 published: '2026-08-26' install: helm install linkerd-enterprise-control-plane -n linkerd --repo https://helm.buoyant.cloud linkerd-enterprise-control-plane description: Buoyant Enterprise for Linkerd control plane chart. - name: linkerd-enterprise-crds registry: helm registry_url: https://helm.buoyant.cloud official: true language: helm version: 2.20.2 published: '2026-08-26' description: Buoyant Enterprise for Linkerd CRD chart. - name: linkerd-enterprise-multicluster registry: helm registry_url: https://helm.buoyant.cloud official: true language: helm version: 2.20.2 published: '2026-08-26' description: Buoyant Enterprise for Linkerd multi-cluster extension chart. - name: linkerd-buoyant registry: helm registry_url: https://helm.buoyant.cloud official: true language: helm version: 0.40.6 published: '2026-09-02' description: >- The Buoyant Extension aggregate chart — installs the Buoyant Cloud agent and the Linkerd dashboard components that talk to api.buoyant.cloud. - name: linkerd-preview-control-plane registry: helm registry_url: https://helm.buoyant.cloud official: true language: helm version: 26.8.4 published: '2026-08-25' description: Preview (pre-release) channel of the Buoyant Enterprise Linkerd control plane. - name: github.com/BuoyantIO/linkerd-buoyant registry: go registry_url: https://pkg.go.dev/github.com/BuoyantIO/linkerd-buoyant official: true language: go version: v0.40.6 published: '2026-08-26' description: >- Go module for the Buoyant Cloud agent and the linkerd-buoyant CLI extension.

CURRENCY FINDING — the stable channel index has not published a new chart since 2024-02-20; Buoyant moved stable/supported releases into Buoyant Enterprise for Linkerd and the OSS project now ships on the edge channel.

CURRENCY FINDING — the formula declares version "stable-2.12.4" and installs by shelling out to https://buoyant.cloud/install-edge, so the pinned version string no longer describes what is installed. published is null because a Homebrew tap has no registry metadata endpoint and the GitHub commit API was rate-limited at probe time; the version was read from the formula source. - name: linkerd CLI registry: cdn registry_url: https://run.linkerd.io/install official: true language: shell version: null published: null install: curl --proto '=https' --tlsv1.2 -sSfL https://run.linkerd.io/install | sh description: >- Official open-source Linkerd CLI installer.
