I did some major updating today and every post I updated, even ones published in 2005, got picked up again by the RSS feed. It’s the exact opposite problem this guy is having – https://en.forums.wordpress.com/topic/how-can-i-force-an-update-to-rss
I posted this question a couple of years ago when I noticed the exact same problem. I don’t want my subscribers to get a new update in their reader every time I update a post (because we all know it happens, you push “publish” and then notice a huge spelling issue or something).
In small words – I update old posts, old posts show up again in RSS feed. This should not be happening.
