Dude on RouterOS

What’s the latest version combination of RouterOS and The DUDE I can run? I have a recent install (3.13) of RouterOS on an x86 system, but I can’t find a Dude package to download and install on it.

We are currently running the Dude 2.x on a Windows server, but would like to migrate it to RouterOS.

Dude is included in all packages,
