I have experienced this. Asking questions about a new version of something, and having it closed with a pointed to a prior version of things that explicitly does not work any more.
Then edit your question to acknowledge the "duplicate" and clearly explain why your question is different. It will automatically go into a Reopen Queue where users will evaluate it and vote to reopen. The system's not perfect, so if it still doesn't get reopened, open a discussion on meta.
