I'm running the 4-23 nightly.
I've noticed that the RSS 2.0 feed sends the entire body of my post with the feed (which I don't want), but the RSS .92 sends only a short summary.
I went back to edit one of the longer entries and typed in an excerpt and updated it, but alas, it's still sending the entire body of text.
Everything validates just fine, I'd just prefer if they only got a summary or short excerpt.
I'm sorry if this was brought up earlier and I missed it. My keyword search came up fruitless.
