Try https://kotlinlang.org/.

It works with JDK 6+.

What does this mean?

They probably require JDK8 for compiling/building the class files, but can you target 1.7?

Keen eye! The release is tagged and the artifacts are indeed on maven central, but we are holding the official announcement for a few days to be able to launch with a nice set of community libraries already published. So much for flying under the radar :-)

True Scala 2.12 generates byte code that requires a Java 8 VM. Scala 2.11 will be supported for a while longer, with as many as the 2.12 features implemented there first (those that don't require Java 8).

AFAIK no, 2.12 does a lot to be compatible with equivalent native features of JVM 8. The way to target JVM 7 bytecode is to stick with Scala 2.11.
