Thanks! Just added both, RSS at https://ccwatch.net/feed.xml and JSON Feed at https://ccwatch.net/feed.json. Wasn't sure whether to cap the number of items so I just went with all 230+ releases, full changelog content included. I hope that works well for you (and everyone else).
It's super simple. HTML + CSS + JS and a node script that's executed via CRON that populates `data.json` (every 10 minutes so I don't have to auth with Github). And then the "static" frontend just fetches the updated `data.json` and works with it. You can check the JSON here https://ccwatch.net/data.json.
