Hi, I was wondering what the difference is between the “updated_at” field that is returned in the JSON response body and the “Last-Modified” response header. I noticed that when getting specific pull requests (using GET /repos/:owner/:repo/pulls/:pull_number), the “updated_at” field and “Last-Modified” header don’t always line up. I can’t figure out what has been modified, even after pull requests have been merged. Does the modification. have to do with something else?
