Hello,

The Apache Curator team is pleased to announce the release of version
4.1.0. Apache Curator is a Java/JVM
client library for Apache ZooKeeper[1], a distributed coordination service.
Apache Curator includes
a high-level API framework and utilities to make using Apache ZooKeeper
much easier and more reliable.
It also includes recipes for common use cases and extensions such as
service discovery and a Java 8
asynchronous DSL. For more details, please visit the project website:
http://curator.apache.org/

The most recent source release can be obtained from an Apache Mirror:
http://www.apache.org/dyn/closer.cgi/curator/
(mirror sync times may vary)

The binary artifacts for Curator are available from Maven Central and its
mirrors.
