> * Add a new module so that backward compatibility with 3.5 is ensured
> * Add new methods corresponding to {{ZooKeeper.addWatch()}}
> * Add a new recipe that enables a fully managed Persistent watch
> * Create new Cache recipes that use the new Persistent watch recipe
> * Replace internal usages of TreeCache/PathChildrenCache/NodeCache with new
> cache recipe
> * Deprecate TreeCache/PathChildrenCache/NodeCache
> * Updated docs/tests/etc
