In the early days of WPf2b the WP (WordPress.org) support forum was a friendly place and covered more than just support. As WPf2b matured so did the forum, but recently things have changed – and not for the better.
Using the "California Consumer Privacy Act" as an excuse, MaxMind have decided to make it far more difficult to use their geolocation databases; quite how the CCPA applies to a country database is beyond me, but that's what they've done.
Put simply, you now need to register and then get a license key. WPf2b v4.3 adds support for this new inconvenience, and v4.4 will add support for a database that doesn't require registration.

WPf2b v4.3 now fully supports multisite networks in both the Free and Premium versions.
The biggest change is that WPf2b is now a "network-only" plugin; in other words, it can only be activated at the network level. Previously you could activate WPf2b for individual sites, which frankly made no sense at all.
For the Free version this has no effect beyond individual site admins no longer being able to see the WPf2b settings, but for the Premium version there are two important changes:
