Getting Started

Announcing the release of Apache Samza 1.6.0

We are thrilled to announce the release of Apache Samza 1.6.0.

Bug Fixes:

In 1.6 release we fixed multipe issues and refactored some code. This includes correct shutdown flow for Kafka clients (and thus avoiding confusing error messages), consolidation of Beam and High/Low Samza launch workflow, and more. For applications that are already on Samza 1.5.0, updating your dependencies to use Samza 1.6.0 should be sufficient to upgrade. For applications that are on version 1.4 & below, please see instructions for 1.5.1 upgrade.
