Scala compatibility

Currently we do support Scala 2.11 and 2.12, we cross publish versions.

Flink compatibility

We currently support only one Flink version (more or less latest one, please see flinkV in build.sbt). However, it should be possible to run Nussknacker with older Flink version.

While we don't provide out-of-the-box support as it would complicate the build process, there is separate repo with detailed instructions how to run Nussknacker with some of the older versions.
