 - The `power.ups` module now generates `upsd.conf`, `upsd.users` and `upsmon.conf` automatically from a set of new configuration options. This breaks compatibility with existing `power.ups` setups where these files were created manually. Back up these files before upgrading NixOS.
 
+- `programs.nix-ld.libraries` no longer sets `baseLibraries` via the option's default but in config and now merges any additional libraries with the default ones.
+  This means that `lib.mkForce` must be used to clear the list of default libraries.
+
 - `pdns` was updated to version [v4.9.x](https://doc.powerdns.com/authoritative/changelog/4.9.html), which introduces breaking changes. Check out the [Upgrade Notes](https://doc.powerdns.com/authoritative/upgrading.html#to-4-9-0) for details.
 
 - `unrar` was updated to v7. See [changelog](https://www.rarlab.com/unrar7notes.htm) for more information.
