The Apache Beam community is pleased to announce the availability of the 0.5.0 release.
Apache Beam is a unified programming model for both batch and streaming data processing, enabling efficient execution across diverse distributed execution engines and providing extensibility points for connecting to different technologies and user communities. This release adds support for stateful pipelines via the new State API, and timers via the new Timer API. Additionally, the release adds new IO connectors for Elasticsearch and MQ Telemetry Transport (MQTT), along with a usual batch of bug fixes and improvements. For all major changes in this release, please refer to the release notes . The 0.5.0 release is now the recommended version; we encourage everyone to upgrade from any earlier releases. We thank all users and contributors who have helped make this release possible. If you haven't already, we'd like to invite you to join us, as we work towards our first release with API stability. - Davor Bonaci, on behalf of the Apache Beam community.  https://beam.apache.org/get-started/downloads/  https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12319527&version=12338859
