- `buildPythonPackage`, `buildPythonApplication` and the Python building setup hooks now support both `__structuredAttrs = true` and `__structuredAttrs = false`.
- `services.dex` now restarts upon changes to the `.environmentFile` or entries in `.settings.staticClients[].secretFile` when the entry is a `path` type. - `services.dex` now restarts upon changes to the `.environmentFile` or entries in `.settings.staticClients[].secretFile` when the entry is a `path` type.
- `nixos-rebuild-ng`, a full rewrite of `nixos-rebuild` in Python, is available for testing. You can enable it by setting [system.rebuild.enableNg](options.html#opt-system.rebuild.enableNg) in your configuration (this will replace the old `nixos-rebuild`), or by adding `nixos-rebuild-ng` to your `environment.systemPackages` (in this case, it will live side-by-side with `nixos-rebuild` as `nixos-rebuild-ng`). It is expected that the next major version of NixOS (25.11) will enable `system.rebuild.enableNg` by default. - `nixos-rebuild-ng`, a full rewrite of `nixos-rebuild` in Python, is available for testing.

- The representation of the flags attributes as shell/environment variables for most Python building setup hooks are now the same as `stdenv.mkDerivation` and other build helpers -- they are space-separated environment variables when `__structuredAttrs = false` and Bash arrays when `__structuredAttrs = true`, and are concatenated to the command without Bash-evaluation. The following behaviour changes are introduced during the conversion:
- The following flags are no longer Bash-expanded before concatenated to the command:
- `disabledTests` and `disabledTestPaths` for `pytestCheckHook`. (`disabledTestPaths` used to be expanded twice before concatenation.)
- `setupPyBuildFlags` and `setupPyGlobalFlags` for `setuptoolsBuildHook`.
- `pytestFlags` and `unittestFlags` replace `pytestFlagsArray` and `unittestFlagsArray` and become the new and conforming interface.
- `pytestFlagsArray` and `unittestFlagsArray` are kept for compatibility purposes. They continue to be Bash-expanded before concatenated. This compatibility layer will be removed in future releases.
