 + `apps.emqx.io/v2beta1 EMQX`.
 
-  + Fix the issue of sometimes the new EMQX pod can't start, including scale-up and blue-green deployment.
+  + Sometimes the updated statefulSet / replicaSet will not be ready, because the EMQX node can not be started. Then we will roll back EMQX CR spec, the EMQX operator controller will create a new statefulSet / replicaSet. But the new statefulSet / replicaSet will be the same as the previous one, so we didn't need to create it, just change the EMQX status.
