 - the `ankisyncd` package and its `services.ankisyncd` have been removed, use [`services.anki-sync-server`](#opt-services.anki-sync-server.enable) instead.
 
+- The `octoprint` service has gained an `enableRaspberryPi` option, which will
+  be disabled for state versions following 25.05. Users running on Raspberry Pi
+  should enable the option to restore full functionality.
+
 - `nodePackages.vscode-css-languageserver-bin`, `nodePackages.vscode-html-languageserver-bin`,
   and `nodePackages.vscode-json-languageserver-bin` were dropped due to an unmaintained upstream.
   The `vscode-langservers-extracted` package is a maintained drop-in replacement.
