@klein0r Cool many thanks for this huge update! Just tell when you are done then I do a final look over it and we can release that (minor or major WDYT?)

@Apollon77 I'm done so far. I will respond / check further issues if this is merged. Please release a major version, since I've changed a lot (e.g. admin config requires to re-enter all passwords). See added message in the io-package.json.

@Apollon77 ping before dependabot creates merge conflicts by end of month 😄
