I noticed that a lot of news websites change their news article ( change the title or add and remove sentances and words from the article) without any notice.
All of that left me wondering if there is any news website with changelogs or that is based on git or anything similar that would result in documenting the changes in news articles.
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”
