This is likely. We re-designed the entire concept of privacy levels (hide only domains, hide domains + clients, hide everything) to give you more fine-grained control over what kind of statistics you want to gather for your network if you are privacy-concerned. This allows to get the most statistics still with a level of privacy you feel comfortable with.
Yeah, need to update the documentation in more places, I guess (I wrote it somewhere, but now cannot find it myself )
Use, e.g.
pihole -a privacylevel 0
to set it to zero (no blocking). There are also 1 (domains), 2 (domains + clients), and 3 (everything) as described on the settings page. They are immediately effective and do not require a restart of FTL (they are the only FTL config flag with this property, so far).
