Release Notes

Highlights Flux v2.9.5 is a patch release that moves helm-controller and source-controller back to upstream Helm, now at v4.2.4, dropping the temporary Flux fork. It hardens the handling of kubeconfig Secrets in helm-controller and kustomize-controller, which now reject kubeconfigs referencing files on the local filesystem and require credentials and certificates to be embedded inline. It also stops kustomize-controller from leaving behind the temporary directories of a previous process that exited without running its cleanup, and fixes a crash in post-build substitution where a substring expression with a negative length, e.g. ${VAR:2:-1}, panicked instead of counting back from the end of the string like Bash does. Across all controllers and the CLI, the fluxcd/pkg dependencies have been updated, bringing Kubernetes to 1.36.4. Users are encouraged to upgrade for the best experience. ℹ️ Please follow the Upgrade Procedure for Flux v2.7+ for a smooth upgrade from Flux v2.6 to the latest version. Fixes:

  • Validate kubeconfigs from .spec.kubeConfig Secrets, rejecting local file references in certificate-authority, tokenFile, client-certificate and client-key; credentials and certificates must be embedded inline (helm-controller, kustomize-controller)
  • Purge temporary directories at startup (kustomize-controller)
  • Fix panic on negative-length substring expressions in post-build substitution (kustomize-controller, flux CLI) Improvements:
  • Move back to upstream Helm v4.2.4, dropping the Flux fork (helm-controller, source-controller)
  • Update fluxcd/pkg dependencies, which bring Kubernetes to 1.36.4 (all controllers, flux CLI)
