Regarding the title thing. Lots of news sites will have multiple titles that get swapped at random. The different wordings increase the click through rate. You might not be interested in title 1,2 or 3, but title 4 gets you to click.
But as for change logs for the actual article, none that I know of. The best you normally see is something like “last edited 5 minutes ago”
It’s non-stop-nut-November!
