-`programs.light` was removed from nixpkgs due to the corresponding package being unmaintained upstream. `brightnessctl` and `programs.acpilight` offer replacements.
-`ceph` has been upgraded to v20. See the [Ceph "tentacle" release notes](https://docs.ceph.com/en/latest/releases/tentacle/#v20-2-0-tentacle) for details and recommended upgrade procedure.
Note that **upgrades of server-side components are one-way**, and downgrading e.g. an OSD from *Tentacle* to *Squid* is not just not supported but is known to break.
- The `networking.wireless` module has been security hardened by default: the `wpa_supplicant` daemon now runs under an unprivileged user with restricted access to the system.
As part of these changes, `/etc/wpa_supplicant.conf` has been deprecated: the NixOS-generated configuration file is now linked to `/etc/wpa_supplicant/nixos.conf` and `/etc/wpa_supplicant/imperative.conf` has been added for imperatively configuring `wpa_supplicant` or when using [allowAuxiliaryImperativeNetworks](#opt-networking.wireless.allowAuxiliaryImperativeNetworks).
