Scala 2.11.0 was released in April 2014 and support for 2.11.x ended in Nov 2017. Scala 2.12.0 was released in Nov 2016 and Scala 2.13.0 will be released in Q1 2019. Given this, it's time to consider dropping support for Scala 2.11 so that we keep the testing matrix manageable and for better interop with Java 8 functional interfaces introduced by Scala 2.12.
