This one is breaking, right? (due to the feed view being renamed)

[Gummibeer]

No, I've kept the feed view which now only includes the atom view. This way it non BC and in the next major release the feed view could get removed.

During next major release it could also be an idea to remove the feed type from config or make it an array to allow to render the same feed in multiple types. The route should get a suffix .rss, .atom or .json for the new JSON feed type.

Thanks! I think we can create a new major version when PHP 7.4 arrives. For this (and other package) the plan is to create PHP 7.4 only new major version where we can use typed properties, short closures and all the sweetness that PHP 7.4 brings to the table.
