Concerning this API endpoint:
An example JSON record given below, as sent by the stream. Notice when checking the diff https://arz.wikipedia.org/w/index.php?diff=5641431 it does not match the links in the JSON. This JSON record is sent repeatedly by the stream, maybe 10 days in a month and 1 to 7 times per day. The diff number and article title changes, but the set of links in the JSON stay the same repeating.
