+We are happy to present the new 2.13.0 release of Beam. This release includes both improvements and new functionality.
+See the [download page]({{ site.baseurl }}/get-started/downloads/#2130-2019-05-21) for this release.<!--more-->
+For more information on changes in 2.13.0, check out the
+[detailed release notes](https://jira.apache.org/jira/secure/ReleaseNote.jspa?projectId=12319527&version=12345166).
+
+## Highlights
+
+### I/Os
+
+* Support reading query results with the BigQuery storage API.
+* Support KafkaIO to be configured externally for use with other SDKs.
+* BigQuery IO now supports BYTES datatype on Python 3.
+* Avro IO support enabled on Python 3.
+* For Python 3 pipelines, the default Avro library used by Beam AvroIO and Dataflow workers was switched from avro-python3 to fastavro.
+
+
+### New Features / Improvements
+
+* Flink 1.8 support added.
+* Support to run word count on Portable Spark runner.
+* ElementCount metrics in FnApi Dataflow Runner.
+* Support to create BinaryCombineFn from lambdas.
+
+
+### Breaking Changes
+* When writing BYTES Datatype into Bigquery with Beam Bigquery IO on Python DirectRunner, users need to base64-encode bytes values before passing them to Bigquery IO. Accordingly, when reading bytes data from BigQuery, the IO will also return base64-encoded bytes. This change only affects Bigquery IO on Python DirectRunner. New DirectRunner behavior is consistent with treatment of Bytes by Beam Java Bigquery IO, and Python Dataflow Runner.
+
+
+### Bugfixes
+
+* Various bug fixes and performance improvements.
