   > Will the zookeeper team test the compatibility for 3.4.x server when releasing new 3.5.x zookeeper?
   
   They should be compatible as long as you're not using some new API. There was a discussion about the topic on the user list recently: http://markmail.org/thread/gtjod534odnb3w4y
   HBase has been mentioned in the thread by Enrico who's running it with 3.5 client against 3.4 servers. (I'm not sure about the specifics.)
   
   > And what is the advantage to upgrade to 3.5.x? 
   
   Support 3.5 servers, take advantage of new features, performance, stability improvements. Please check out the release notes.
   
   > The 3.4.x will be EOL soon?
   
   I think 3.4.x will be EOL later rather than sooner. We're going to have a new major release 3.6.0 some time this year and after that we'll deco the 3.4.x branch in order to avoid supporting 3 major branches at the same time.
