Hellooooooooooooooo everybody !!! Nicolas thought that it would be wiser to send a warning to everybody about patches #13747 and #13742, which make backward-incompatible to Sage **and are now positively reviewed**. They affect the default behaviour of two objects :
#13747 (Changes the behaviour of Permutations) : permutation methods are currently written to handle permutations on 1...n. Hence, creating a permutation with different input values should be forbidden. Now, it is. Use the optional flag Permutation( whatever, check_input = True) to get the old behaviour back #13742 (Changes to Posets) : The former meaning of "facade = None" (which is the default parameter) was "facade = False". Now, it means "facade = True". If you want to get the old behaviour back, explicitely add "facade = False" to your Poset( .... ) calls. Besides, the "facade" argument is now... "documented". And by this I mean "as documented as I can make it" :-) That's all. And there will be no problem with your code until Jeroen comes back from his well-deserved vacations :-) Have fuuuuuuuuuuuuuuuuuuuuuuunn !
