- `python3.pkgs.flitBuildHook` has been removed. Use `flit-core` and `format = "pyproject"` instead.



-  Now `magma` defaults to `magma-hip` instead of `magma-cuda`. It also

   respects the `config.cudaSupport` and `config.rocmSupport` options.



- The `extend` function of `llvmPackages` has been removed due it coming from the `tools` attrset thus only extending the `tool` attrset. A possible replacement is to construct the set from `libraries` and `tools`, or patch nixpkgs.



- The `qemu-vm.nix` module now supports disabling overriding `fileSystems` with
