is 3.5.0-rc1 client compatible with 3.4.6 server?

I need to use the new feature of ZOOKEEPER-1355
<https://issues.apache.org/jira/browse/ZOOKEEPER-1355>
zk.updateServerList(newServerList) that is only available in 3.5 release at
client side. But our server is still at 3.4.6. do you seen any issues with
using 3.5 client with 3.4 server ?

Thanks,
Steven

this is running in cloud/aws env. During zookeeper server push, I need to
call updateServerList with the same list of hostnames. The purpose is to
refresh the resolved private IP even though hostname or public IP is still
the same.

I am trying to get some confirmation regarding general usage of 3.5 client
with 3.4 server.

w.r.t. updateServerList itself, I think it should work. However you'll have
to get newServerList from somewhere - I don't think you can get it from the
API in 3.4.6. The client has the new getConfig() and reconfig() commands
but the server won't recognize them.

I'm not sure what else could break, perhaps others can comment.
