Version.getRevision() has been removed in these 3 versions of ZooKeeper. It has been restored in version 3.5.8 and 3.6.1 and will remain for backward compatibility reasons until version 3.7.0 most likely. Keep in mind this function is deprecated and only returns -1, as git has a string hash and not an integer revision number. Please use getRevisionHash() instead.

Metric "followers" (or "zk_followers") renamed to "learners" ("zk_learners") in 3.6.0

Please note that in ZOOKEEPER-3117 we corrected the name of a metric that contained (even in the previous ZK versions) the number of all Learners connected to the ZooKeeper Leader. The learners can be either followers or observers, so the previous ('follower') name was misleading. This metric gets exposed e.g. on the admin API or with the "mntr" 4 letter word command.
