 - `pass` now does not contain `password-store.el`.  Users should get `password-store.el` from Emacs lisp package set `emacs.pkgs.password-store`.
 
+- `services.knot` now supports `.settings` from RFC42.  The change is not 100% compatible with the previous `.extraConfig`.
+
 - `mu` now does not install `mu4e` files by default.  Users should get `mu4e` from Emacs lisp package set `emacs.pkgs.mu4e`.
 
 - `mariadb` now defaults to `mariadb_1011` instead of `mariadb_106`, meaning the default version was upgraded from 10.6.x to 10.11.x. See the [upgrade notes](https://mariadb.com/kb/en/upgrading-from-mariadb-10-6-to-mariadb-10-11/) for potential issues.
