In this release, we also support for arbitrary stateful operations in a stream, and Apache Kafka 0.10 support for both reading and writing using the streaming and batch APIs. In addition to extending new functionality to SparkR, MLlib, and GraphX, the release focuses on usability, stability, and refinement, resolving over 1100 tickets.
This blog post discusses some of the high-level changes, improvements and bug fixes:
Production ready Structured Streaming
Expanding SQL functionalities
New distributed machine learning algorithms in R
Additional Algorithms in MLlib and GraphX
