In Wallabag 2.3.0 author and publication date are available. Please show them in the app.

If I understood the app code correctly, it is using this API wrapper written by @di72nn. So, first the API wrapper needs to have these new fields, then one can add this to the app (which shouldn't be that hard).
This is still an issue. Is it hard to fix?
