        **IMPORTANT!!!**: For all ComNetsEmu users and developers:
        
        **Please** run the upgrade process described [here](https://git.comnets.net/public-repo/comnetsemu#upgrade-comnetsemu-and-dependencies) when there is a new release
        published [here](https://git.comnets.net/public-repo/comnetsemu/-/tags).
        New features, fixes and other improvements require run the upgrade script **manually**.
        But the script will check and perform upgrade automatically and it does not take much time if you have a good network connection.
