    New Features

    Support for Open Nashorn

    Now your pipeline definitions can include your choice of JavaScript engine, either "Nashorn" or "OpenJDK Nashorn". You can select the JavaScript engine in the pipeline views. Your JavaScript pipeline stages are interpreted by the selected engine.

    While Nashorn is the default option, it is in the process of being deprecated and will eventually be removed, so it is recommended to use OpenJDK Nashorn when possible.
