We updated the web UI to make keeping forks in sync with their upstream repositories more intuitive. "Fetch upstream" has been renamed to "Sync fork," which better describes the button's behavior. If the sync causes a conflict, the web UI prompts users to contribute their changes to the upstream, discard their changes, or resolve the conflict.
