As long as your Curator 4.x app targets ZooKeeper 3.5.x you should be binary 
compatible. However, there are a very few breaking changes (and thus the major 
version number increment) that we document here: 
https://github.com/apache/curator/blob/master/src/site/confluence/breaking-changes.confluence
 
<https://github.com/apache/curator/blob/master/src/site/confluence/breaking-changes.confluence>
 (the formatting will be better when we generate the website). Note: we have a 
new module that tests against ZooKeeper 3.5.x: 
https://github.com/apache/curator/tree/master/curator-test-zk35

Is there a particular concern you have?
