Important changes

The New Microflow Debugger

You can now debug your Mendix applications running at a remote location, using the new microflow debugger that is fully integrated into the Mendix Business Modeler.

Debugging your app: * Connect locally to the application running in your Modeler, or remotely to an application running in the Mendix Cloud or on premise. * Easily step through your microflows and inspect all available variables. * Enable and disable the debugger for cloud applications using the cloud dashboard.

Version selector

This application is installed automatically with the modeler and associates itself with Mendix project files and Mendix packages. It selects the correct modeler version to open the file when it is installed. If not, it will let you choose another modeler install or allow you to download the exact version in the Mendix App store.

Mobile image uploader

The image uploader widget can now be used in mobile forms. It allows you to take a new picture with the camera (iOS >= 6, Android >= 3) or choose an existing one (Android 2).

Remote runtime access

When running on premise and using a reverse proxy on a different server than the application, you should enable remote access to the runtime. For this, you need to have the latest version of the Windows service console or m2ee-tools for Linux.

Windows service console
  • set runtime server port listen address to ‘public’ in the configuration screen of your application.
m2ee-tools for Linux
  • update m2ee-tools to the newest version (0.4.4)
  • add the following configuration option to the ‘m2ee’ section of the m2ee.yaml configuration file: runtime_listen_addresses: “*”
