Version 4.0 is now in public Beta stage.

Some of the features are not yet branched but it is fully operational. If you do not want to alter your current profile, you should create a new one and install OutWit Hub 4.0 on it.

Please do send us your feedback on the support system of outwit.com. It is very important to us: the OutWit Kernel represents a very large amount of code and thoroughly testing the application is starting to be a pretty heavy task. We are very grateful for all the help we receive in this phase.
