Recently I was searching Google for an answer to a question I have.
I came across what I thought would be a great answer in Google, but it turned out the answer was a "not supported" answer, which I know isn't the case now. And the fact the question was asked 5 months ago is a confirmation of the fact that the answer is based on a beta SDK that has changed since then.
What is the policy for keeping these types of questions fresh and relevant? They already have accepted answers and have been pretty much abandoned by the original poster, with no valid option to close or re-ask them.
So this is a policy question, in hopes that maybe a mechanism can be put in the system that allows a question to be marked as stale or based on a beta product.
