>             Project: Apache RocketMQ
>          Issue Type: Bug
>          Components: rocketmq-broker
>    Affects Versions: 4.0.0-incubating
>            Reporter: Eric Liu
>            Assignee: yukon
>             Fix For: 4.1.0-incubating
>
>
> When consumers in one group have different subscriptions(with tag), broker 
> will select the one has latest client version. Although when this consumer 
> shutdown, broker would not update the subscription until someone in group  
> restart, so other consumers will miss messages by the dead consumer's tag.
> Broker should refresh the  group's subscriptions when someone was off-line.
