Team, Since version 2.4.0 Spark team decided to introduce support for Scala 2.12 and remain 2.11 for backward compatibility. As part of BAHIR-107, I have been working to upgrade code base to Scala 2.12 and Spark 2.4.0 ( https://github.com/apache/bahir/pull/76/files). Do we plan to continue support for Scala 2.11? In my opinion, Bahir should follow Spark in terms of Scala binary compatibility. I have already checked that transitive dependencies that I had to upgrade (org.json4s:json4s-jackson and com.twitter:algebird-core) provide artifacts for both - Scala 2.11 and 2.12.
