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.
Describe the new thing you want to do in appropriate detail. This may be fairly extensive and have large subsections of its own. Or it may be a few sentences. Use judgement based on the scope of the change.
