[ANNOUNCE] Helix 0.6.2-incubating and 0.7.0-incubating

[Kanak Biscuitwala <ka...@apache.org>]

We are pleased to announce the 0.6.2 and 0.7.0 releases of the Apache Helix project!

Apache Helix is a generic cluster management framework built on top of Apache Zookeeper, that makes it easy to build partitioned, fault tolerant, and scalable distributed systems.

Programming the behavior of a distributed systems especially in the presence of failures can be tricky and error prone. Helix relieves the system developers of this burden by allowing them to declare the behavior of their distributed system via Finite State Machine. In addition to the features provided by Zookeeper, it provides additional capabilities like transparent failover with minimal downtime, cluster expansion and high scalability. By using Helix, you will continue to enjoy the many benefits of Apache Zookeeper while making it easier for
you to build your distributed system.

0.6.2-incubating is a new release with many bug fixes and stability improvements: http://helix.incubator.apache.org/site-releases/0.6.2-incubating-site/releasenotes/release-0.6.2-incubating.html
