There are no releases on the GitHub page: https://github.com/Megus/defold-router @megus.sugem you really should create releases as it becomes a whole lot easier to lock down a specific version of the lib in your game.project file.
You can still lock down a specific version though:
- Browse the changes here: https://github.com/Megus/defold-router/commits/master
- Click the <> button next to the change you wish to use
- Click Clone or Download and then right click Download ZIP and copy the link.
- Paste the link as a dependency in game.project
