Re xmpp.org update: I added some more redirects for blog posts and I think I covered them all now. I also added data driven announcements (e.g. for upcoming events) which can be enabled/edited via an announcement.json file. I think it's ready now :)
Thanks! :) I put the new software rendering in a separate branch for later, in case anyone wonders. What I pushed to the repo can be considered as an unmodified port (content-wise).
