Zookeeper version in github?

Hi folks,

I am using Zookeeper 3.4.6 for a while. Recently, I clone the Zookeeper code
from github (https://github.com/apache/zookeeper). When I build it to
generate jar file, I find that the version is 3.6.0 !!!!!!. I haven’t heard
about this version, as I know there is new version called 3.5.0.

So can anyone tell me what is the version of zookeeper that is located in
the Github?

Thank you

Ibrahim
