I would like to stay updated on the latest LibreOffice releases via RSS feed, like I did on SourceForge. Can you please provide a link to the release RSS feed?
I could not find a specific Libreoffice rss feed but the one of Document Foundation “press releases” seems the closest thing to it. They announce new releases with few other important news

If you want the RSS for the whole blog you can get it from here:
