RSS Feed Location Change
The RSS feed that was available on https://f-droid.org/feed.xml now returns a 404.
Due to !254 (merged), the correct URL is now https://f-droid.org/feed/index.xml .
https://f-droid.org/feed/ will redirect to https://f-droid.org/feed/index.html
(note HTML not XML), which is why the error still exists.
The solution is another redirect, or some .htaccess
trickery involving default index files, or at least a new post on the blog mentioning the change.
