Byteman 2.2.2 has been released and is available from the Maven Central repository and the Byteman project downloads page.
This is a maintenance release which fixes a few bugs (including a regression introduced into script bminstall.sh in release 2.2.1).
The release also introduces one significant new feature, a plugin model to manage loading, unloading and checking the status of the Byteman agent's rule base. So, if you don't like the agent opening a socket listener from within your application you can replace Byteman's TransformListener class with a POJO of your choice and have it take control. Special thanks are due to Red Hat's Gary Brown for contributing the code for this feature.
