Could you please adjust the RSS feed in the new build?

Ideally, <link> and <guid> should contain absolute URLs, not only relative paths.

Also, xmlns:atom is currently declared, but no atom:link is used. It would make sense to add this inside <channel>:

<atom:link href="https://www.mydomain.com/rss/news.xml" rel="self" type="application/rss+xml" />

Please also make sure that special characters are properly escaped in the XML. Especially & should be written as &amp;.

Example:

<channel>
  <title>mydomain.com - Latest News</title>
  <description>RSS feed for the latest news on kaufsonntag.de</description>
  <link>https://www.mydomain.com/</link>
  <atom:link href="https://www.mydomain.com/rss/news.xml" rel="self" type="application/rss+xml" />
  <language>de-DE</language>

Would it be possible to include this in the next build?

If it is not too complex, it would also be great to add the image path for the blog post header image.

This would be a very useful improvement. At the moment, the RSS feed can only be used in a limited way in its current form.
