Laravel 5.5 contains a number of changes which require changes to the library. The full listing of breaking changes is available here. It appears to me the following changes need to be made
[ ] Updating Dependencies
PHP to 7.0
Illuminate/ to 5.5.
phpunit to ~.60
Requires a change to TestCase.php changing the underscores in the phpunit use statement to backslashes
[ ] Update the belongsToMany method signature
Likely rework the logic, as the names are now provided
[ ] Update relationship create methods
BelongsToMany, HasOneOrMany, and MorphOnOrMany signatures have changed
[ ] Soft Deleted models exists property now remains true, so update SimpleCRUDTest to reflect this
