+We are glad to present the new 2.3.0 release of Beam. This release includes
+multiple fixes and new functionalities. <!--more--> For more information
+please check the detailed release notes.
+# New Features / Improvements
+## Beam moves to Java 8
+The supported version of Java for Beam is now Java 8. The code and examples
+been refactored to use multiple of the advantages of the language, e.g.
+streams, improved type inference, etc.
+## Spark runner is now based on Spark 2.x
+Spark runner moves forward into the Spark 2.x development line, this would
+to benefit of improved performance, as well as open the runner for future
+compatibility with the Structured Streaming APIs. Notice that support for Spark
+1.x is finished with this release.
+## Amazon Web Services S3 Filesystem support
+Beam already supported AWS S3 via HadoopFileSystem, but this version brings a
+native implementation with the corresponding performance advantages of the S3
+## General-purpose writing to files
+This release contains a new transform, FileIO.write() / writeDynamic() that
+implements a general-purpose fluent and Java8-friendly API for writing to files
+using a FileIO.Sink. This API has similar capabilities to DynamicDestinations
+APIs from Beam 2.2 but is much easier to use and extend. The
+APIs for writing to files are deprecated by it, as is FileBasedSink.
+## Splittable DoFn support on the Python SDK
+This release adds the Splittable DoFn API for Python SDK and adds Splittable
+DoFn support for Python streaming DirectRunner.
+Progress continues to being able to execute Python on runners other then Google
+Cloud Dataflow and the Go SDK on any runner.
+# Miscellaneous Fixes
+* MapElements and FlatMapElements support using side inputs using the new
+ interface Contextful.Fn. For library authors, this interface is the
+ recommended choice for user-code callbacks that may use side inputs.
+* Introduces the family of Reify transforms for converting between explicit and
+ implicit representations of various Beam entities.
+* Introduces two transforms for approximate sketching of data: Count-Min Sketch
+ (approximate element frequency estimation) and HyperLogLog (approximate
+ cardinality estimation).
+* Staging files on Dataflow shows progress
+* Flink runner is based now on Flink version 1.4.0
+* BigtableIO now supports ValueProvider configuration
+* BigQueryIO supports writing bounded collections to tables with partition
+* KafkaIO moves to version 1.0 (it is still backwards compatible with versions
+* Added IO source for VCF files (Python)
+* Added support for backoff on deadlocks in JdbcIO.write() and connection
+* Improved performance of KinesisIO.read()
+* Many improvements to TikaIO
