Discover ArangoDB 3.0: New Cluster Features
The 3.0 release of ArangoDB will introduce a completely overhauled cluster and marks a major milestone on its road to “zero-maintenance” where you can keep focus on your product instead of your datacenter.

ArangoDB 3.0 Alpha Release: Getting Closer to the Future
There is this German saying “If it takes long enough, it will be all right in the end.” However, since just “all right” isn’t our quality standard this first alpha of 3.0 took us a bit longer to finish up than planned. We´d like to invite you to give this fully tested alpha a serious spin, test the new functionalities and share your thoughts and feedback with us on Slack in our “feedback30” channel
