I think a major backwards compatibility is the order of keyword arguments with default values. Several year ago I had to do mass replacements in my code. I needed Graph.edges(labels=False) and I did `G.edges(False)`. Sage release made the first argument of .edges `vertices` instead of `labels` and my code failed. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
