OpenPnP 2.0 is a major update to OpenPnP and includes many new features and changes to existing features. As part of this upgrade, you will need to reconfigure your machine, but don't panic. Your old configuration is still available and you can downgrade back to 1.0 very easily. Keep reading.
OpenPnP uses a new configuration directory. Instead of .openpnp it uses .openpnp2. Your old configuration, if you had one, is still in .openpnp. If you would like to downgrade back to 1.0 please download the Legacy version.
