Hi there, the current trunk of Tobago has some important changes inside since last the release:
* update of Bootstrap to current release * updating the theme build Dependent of how "deep" an application uses Tobago, there will be some migration steps needed. We document these steps in the demo [1]. To comply with "semantic versioning" [2] Tobago 3.1 needs to be renamed to Tobago 4.0.
