+## 1.8.0
+
+**Release date:** 2021-03-23
+
+This release comes with support for the SMI `v1alpha2` and `v1alpha3` TrafficSplit APIs.
+
+For SMI compatible service mesh solutions like Open Service Mesh, Consul Connect or Nginx Service Mesh,
+[Prometheus MetricTemplates](https://docs.flagger.app/usage/metrics#prometheus) can be used to implement
+the request success rate and request duration checks.

+
+```yaml
+apiVersion: flagger.app/v1beta1
+kind: Canary
+metadata:
+  name: my-canary
+spec:
+  provider: "smi:v1alpha3" # or "smi:v1alpha2"
