 ## Backward Incompatibilities {#sec-release-23.11-incompatibilities}
 
+- The `boot.loader.raspberryPi` options have been marked deprecated, with intent for removal for NixOS 24.11. They had a limited use-case, and do not work like people expect. They required either very old installs ([before mid-2019](https://github.com/NixOS/nixpkgs/pull/62462)) or customized builds out of scope of the standard and generic AArch64 support. That option set never supported the Raspberry Pi 4 family of devices.
+
 - `python3.pkgs.sequoia` was removed in favor of `python3.pkgs.pysequoia`. The latter package is based on upstream's dedicated repository for sequoia's Python bindings, where the Python bindings from [gitlab:sequoia-pgp/sequoia](https://gitlab.com/sequoia-pgp/sequoia) were removed long ago.
 
 - `writeTextFile` now requires `executable` to be boolean, values like `null` or `""` will now fail to evaluate.
