What is the best way to preceed if we notice an answer that is not correct anymore for instance after a protocol update?

The three options I see are:

  • Adding a comment to the answer to notify the author: fair to him but assume he is still participating and willing to update the text.
  • Editing the answer: I think it requires an approbation by the initial author (who may never come again) and the reward for the new author is small.
  • Adding a new answer: it gives more reward to the new author, it may become the accepted answer (helpful for futur readers).

I seems to me that the polite way would be to let a comment and then to add a new answer after some time without response.

    While a comment first followed by an answer would be polite, i think a new answer is ultimately what is desired. Ideally people would flag the previous answer for moderation and we could edit it to add a note that the answer may be out of date? This way a new reader is made aware that they should read the other answers.
