+Welcome to OpenPnP 2.0!
+
+Your configuration is safe.
+
+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.
+
+For a list of all the changes in OpenPnP 2.0, please go to Menu -> About.
+
+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 Stable version from http://openpnp.org/downloads/.
+
+If you are interested in trying the new features in OpenPnP, please be aware that it is currently
+under heavy development and breaking changes are expected to happen regularly until at least
+the third quarter of 2019.
+
+If you have any questions, or problems, or just want to discuss the new features, please join
+the discussion group at http://groups.google.com/group/openpnp.
+
+Thanks for trying OpenPnP 2.0. Onward!
