Hi Patrick, thanks for the quick update! Would it be possible to accept minor formatting inconsistencies still as valid answers? E.g., in the TodoTXT format I unintentionally put a space between "due:" and the corresponding (correct) date and therefore the test returns an error. Best regards, Nicolas

One argument would be, that for the Liskov Substitution Principle, there is actually a formal definition out there, s...

Hi, we have one clarification question regarding Task 2 of Exercise 4. In the assignment, it is stated, that we have to identify those fields and method declarations/definitions which cause their defining class to violate the Dependency-Inversion Principle .
