# Changelog

All notable changes to this project are documented in this file.

## 1.21.0

**Release date:** 2022-05-06

This release comes with an option to disable cross-namespace references to Kubernetes
custom resources such as `AlertProivders` and `MetricProviders`. When running Flagger
on multi-tenant environments it is advised to set the `-no-cross-namespace-refs=true` flag.

In addition, this version enables Flagger to target Istio and Kuma multi-cluster setups.
When installing Flagger with Helm, the service mesh control plane kubeconfig secret
can be specified using `--set controlplane.kubeconfig.secretName`.
