I tried to subscribe to the software RSS feeds (e.g. https://mikrotik.com/download.rss and https://mikrotik.com/current.rss) but they just give me errors (No feed found) when I try to subscribe in Feedbin (my RSS feed reader). What is the recommended way of staying on top of RouterOS releases?

Expirienced the same problem with two other Feedreaders.
Is there any other way of notifications?

https://mikrotik.com/current.rss works with Inoreader, also available by direct link, no issues.
