* The [Scala](https://www.scala-lang.org/) programming language merged a number of [improvements](https://github.com/scala/scala-dev/issues/405) to make the output from its compiler more reproducible. This work is available in the [fifth milestone for the upcoming 2.13.0 release](https://github.com/scala/scala/releases/tag/v2.13.0-M5) and is intended to be [backported to the 2.12 tree](https://github.com/scala/scala/pull/7203)
