Hello again,
just figured out that my rolling restart problems may be caused by
ZOOKEEPER-3829 (c.f. https://github.com/apache/zookeeper/pull/1356),
so I tried to set reconfigEnabled=true as a workaround, but that fails
as Zookeeper attempts to bind to x.x.x.1 instead of 0.0.0.0 (config
still lists 0.0.0.0 for the local node, respectively) during startup
in that case, so that's apparently not feasible in a Docker
environment:

Are there any plans to release 3.6.2 including the above fix?
