F-Droid Build Status was updated to 5.6.4 and no one will get this update. Why? Well, the app is now built reproducibly so if you have it installed you need to uninstall it and then reinstall it. (Yes, we wish this switch to be easier to perform, but the UI is not there yet)
The update is for f-droid itself. It wont auto update itself to the new version.
If i read it correctly the uninstall/install part is for the F-Droid Build Status App and not for F-droid itself.
Ahh. I misunderstood.
