• New deployment mode: Kubernetes scheduler backend
• PySpark performance and enhancements
• New structured streaming execution engine: continuous processing
• Data source v2 APIs for both structured streaming and Spark SQL
• ML on structured streaming
• Image reader
• Stable codegen engine
• Spark History Server v2
• Native ORC support
• Vectorized ORC and SQL cache readers
• Stream-stream Join
