| We are excited as this is the first release the Heron community has distributed a full set of convenience binaries from the released source code while under the Apache Foundation. |
| Heron has had several improvements implemented while in incubation, and the community has learned much along the way.</p> |
| <p>This is a major milestone in the incubation process at the Apache Incubator for Heron.<br> |
| We expect the release of convenience binaries to ease the adoption of Heron in organizations across the world. |
| This goal could not have been achieved without the solid community behind Heron.</p> |
| <p>Here are a few updates since the last release:</p> |
| <ul> |
| <li><a href="https://github.com/apache/incubator-heron/pull/3664/">Improving Kubernetes Resource Handling</a></li> |
| <li><a href="https://github.com/apache/incubator-heron/pull/3651">Adding Prometheus Metrics Rule</a></li> |
| <li><a href="https://github.com/apache/incubator-heron/pull/3669">Use Build Kit Docker feature to shrink the Docker image size</a></li> |
| <li><a href="https://github.com/apache/incubator-heron/pull/3677">Removing unused Bookkeeper Port</a></li> |
| <li><a href="https://github.com/apache/incubator-heron/pull/3688">Use the full featured Zookeeper config generation script</a></li> |
| <li><a href="https://github.com/apache/incubator-heron/pull/3133">Add sum/max/min reducers in Scala</a></li> |
| </ul> |
