- The packages `iw` and `wirelesstools` (`iwconfig`, `iwlist`, etc.) are no longer installed implicitly if wireless networking has been enabled.

- The `fileSystems.<name>.fsType` option no longer has a default value and must be specified by the user. The value `"auto"` still works as before, though its use is generally discouraged.

- `services.uptime` has been removed because the package it relies on does not exist anymore in nixpkgs.

- `services.kubernetes.addons.dns.coredns` has been renamed to `services.kubernetes.addons.dns.corednsImage` and now expects a
