NOTE 1: Update as FYI for others as well: Feedbro 4.2.2 fires "When new article arrives" rules for also updated articles. This means that when the feed author updates an article, you'll get a desktop notification if you have a matching rule.

We'll change this in 4.2.5 (currently in review queue) so that feed article update does NOT fire desktop notification, IFTTT, play sound actions and does NOT mark the updated article as unread.

NOTE 2: To everyone wondering why they got some duplicate entries in some of their Atom feeds: it can happen just once per feed and is related to an internal change (we added GUID checking and the old existing entries in your local database didn't have GUID values because those weren't supported before). Long story short: even if you might get some duplicates after updating due to this, you won't get them in the future for those feeds since the GUID checking will prevent that.

Can you send the feed URL that is causing this to feedbro.reader@gmail.com please?
