   The `{aclUse,superUser,disableActions}` attributes have been renamed, `pluginsConfig` now also accepts an attribute set of booleans, passing plain PHP is deprecated.
   Same applies to `acl` which now also accepts structured settings.
 
+- The `zsh` package changes the way to set environment variables on NixOS systems where `programs.zsh.enable` equals `false`.  It now sources `/etc/set-environment` when reading the system-level `zshenv` file.  Before, it sourced `/etc/profile` when reading the system-level `zprofile` file.

 - The `wordpress` service now takes configuration via the `services.wordpress.sites.<name>.settings` attribute set, `extraConfig` is still available to append  additional text to `wp-config.php`.
 
 - To reduce closure size in `nixos/modules/profiles/minimal.nix` profile disabled installation documentations and manuals. Also disabled `logrotate` and `udisks2` services.
