Yeah well,with failing tests we can not merge it.

[MatteoGranziera]

@Uzlopak yes of course, any help for the tests?
Doesn't work using master either, could be tap version problem?

[Uzlopak]

Master is broken?
Will have a look shortly

Seems like it, updating the dependencies in my local branch breaks it.
