I realize this is probably not exactly the right place, but it's the closest I could find.
The changelog page at https://matomo.org/changelog/ is missing an app-discoverable link to the RSS feed. The following one-line addition to the HTML head would resolve this:
<link rel="alternate" type="application/rss+xml" href="https://matomo.org/changelog/feed" title="Changelog Matomo">
I also noticed that the visual link to the RSS page is rendered twice, which I'm guessing is not intentional 🙂 .
