Apache Spark development continues to accelerate, with AMPLab-initiated components such as MLlib, GraphX, and Spark Streaming getting significant updates and improvements.   The release also has major performance enhancements and new features for SparkSQL (which has replaced the much-loved Shark implementation).

From the Apache Spark website: “Spark 1.1 represents the work of 171 contributors, the most to ever contribute to a Spark release!”
