Many people here don't seem to understand what is meant by backwards compatibility in the context of the JVM. Scala has very good source compatibility, this means that scala code from 2012 compiles just fine with the latest scala compiler.
Compared to Java, Scala has poor binary compatibility between mayor releases: a library compiled with scala 2.10 will not work with scala 2.11 In java you can use jars created with java 1.3 in your java 8 project.
Go doesn't guarantee binary compatibility either, they (just like scala) guarantee source compatibility.
