 - There is a new NixOS option when writing NixOS tests `testing.initrdBackdoor`, that enables `backdoor.service` in initrd. Requires `boot.initrd.systemd.enable` to be enabled. Boot will pause in stage 1 at `initrd.target`, and will listen for commands from the `Machine` python interface, just like stage 2 normally does. This enables commands to be sent to test and debug stage 1. Use `machine.switch_root()` to leave stage 1 and proceed to stage 2.

+### Breaking changes {#sec-release-23.11-lib-breaking}
+
+- [`lib.lists.foldl'`](https://nixos.org/manual/nixpkgs/unstable#function-library-lib.lists.foldl-prime)
+  now always evaluates the initial accumulator argument first.
+  If you depend on the lazier behavior, consider using [`lib.lists.foldl`](https://nixos.org/manual/nixpkgs/unstable#function-library-lib.lists.foldl)
+  or [`builtins.foldl'`](https://nixos.org/manual/nix/stable/language/builtins.html#builtins-foldl') instead.
+- [`lib.attrsets.foldlAttrs`](https://nixos.org/manual/nixpkgs/unstable#function-library-lib.attrsets.foldlAttrs)
+  now always evaluates the initial accumulator argument first.
+- Now that the internal NixOS transition to Markdown documentation is complete,
+  `lib.options.literalDocBook` has been removed after deprecation in 22.11.
+- `lib.types.string` is now fully deprecated and gives a warning when used.
+
+### Additions and improvements {#sec-release-23.11-lib-additions-improvements}
+
+- [`lib.fileset`](https://nixos.org/manual/nixpkgs/unstable#sec-functions-library-fileset):
+  A new sub-library to select local files to use for sources,
+  designed to be easy and safe to use.
+
+  This aims to be a replacement for `lib.sources`-based filtering.
+  To learn more about it, see [the tutorial](https://nix.dev/tutorials/file-sets).
+
+- [`lib.gvariant`](https://nixos.org/manual/nixpkgs/unstable#sec-functions-library-gvariant):
+  A partial and basic implementation of GVariant formatted strings.
+  See [GVariant Format Strings](https://docs.gtk.org/glib/gvariant-format-strings.html) for details.
+
+  :::{.warning}
+  This API is not considered fully stable and it might therefore
+  change in backwards incompatible ways without prior notice.

+
+  [`mkPackageOption`](https://nixos.org/manual/nixpkgs/unstable#function-library-lib.options.mkPackageOption).
+  now also supports the `pkgsText` attribute.
+
+Module system:
+- Options in the `options` module argument now have the `declarationPositions` attribute
+  containing the position where the option was declared:
+  ```
+  $ nix repl -f '<nixpkgs/nixos>'
+  [...]
+  nix-repl> :p options.environment.systemPackages.declarationPositions
+  [ {
+    column = 7;
+    file = "/nix/store/vm9zf9wvfd628cchj0hdij1g4hzjrcz9-source/nixos/modules/config/system-path.nix";
+    line = 62;

+- Improved error message for option declarations missing `mkOption`
+
+### Deprecations {#sec-release-23.11-lib-deprecations}
+
+- `lib.meta.getExe pkg` (also available as `lib.getExe`) now gives a warning if `pkg.meta.mainProgram` is not set,
+  but it continues to default to the derivation name.
+  Nixpkgs accepts PRs that set `meta.mainProgram` on packages where it makes sense.
+  Use `lib.getExe' pkg "some-command"` to avoid the warning and/or select a different executable.
