I enjoy the option to subscribe to the Releases category, but I’m getting too many emails about beta software.
Please consider separating the RC releases and the Final release announcements into their own categories.
Alternatively, I would consider subscribing to a tag, but if you look at the latest final release announcement you will see no tags on it.
You could subscribe to the RSS feed of the Release tags at the Nextcloud git repository:

We rather try to cut down on the number of categories, so it would be rather a tag to discuss. Like major-release and minor-release? Or just one for both. All the testing stuff, we already added a beta tag in the past (often afterwards), and also related problems and questions regarding testing of versions that were not released yet.
