 ## Backward Incompatibilities {#sec-release-21.11-incompatibilities}
 
+- The `services.wakeonlan` option was removed, and replaced with `networking.interfaces.<name>.wakeOnLan`.
+
 - The `security.wrappers` option now requires to always specify an owner, group and whether the setuid/setgid bit should be set.
   This is motivated by the fact that before NixOS 21.11, specifying either setuid or setgid but not owner/group resulted in wrappers owned by nobody/nogroup, which is unsafe.
