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)
Because there will be a signature mismatch. Apps built by F-Droid will use the F-Droid signature, reproducible apps will use the dev signature.
