# Nixpkgs 25.05 (2025.05/??) {#sec-nixpkgs-release-25.05}

## Backward Incompatibilities {#sec-nixpkgs-release-25.05-incompatibilities}

<!-- To avoid merge conflicts, consider adding your item at an arbitrary place in the list instead. -->

- `services.rippled` has been removed, as `rippled` was broken and had not been updated since 2022.

- `services.rippleDataApi` has been removed, as `ripple-data-api` was broken and had not been updated since 2022.

- The `rustPlatform.fetchCargoTarball` function is deprecated, because it relied on `cargo vendor` not changing its output format to keep fixed-output derivation hashes the same, which is a Nix invariant, and Cargo 1.84.0 changed `cargo vendor`'s output format.
  It should generally be replaced with `rustPlatform.fetchCargoVendor`, but `rustPlatform.importCargoLock` may also be appropriate in some circumstances.
  `rustPlatform.buildRustPackage` users must set `useFetchCargoVendor` to `true` and regenerate the `cargoHash`.

### Titanium removed {#sec-nixpkgs-release-25.05-incompatibilities-titanium-removed}

- `titaniumenv`, `titanium`, and `titanium-alloy` have been removed due to lack of maintenance in Nixpkgs.

## Nixpkgs Library {#sec-nixpkgs-release-25.05-lib}

### Breaking changes {#sec-nixpkgs-release-25.05-lib-breaking}

- Structure of the `functor` of some types has changed. `functor` is an implementation detail and should not be relied upon. If you did rely on it let us know in this [PR](https://github.com/NixOS/nixpkgs/pull/363565).
  - [`lib.types.enum`](https://nixos.org/manual/nixos/unstable/#sec-option-types-basic): Previously the `functor.payload` was the list of enum values directly. Now it is an attribute set containing the values in the `values` attribute.
  - [`lib.types.separatedString`](https://nixos.org/manual/nixos/unstable/#sec-option-types-string): Previously the `functor.payload` was the seperator directly. Now it is an attribute set containing the seperator in the `sep` attribute.

- The `tinycc` package now has the `dev`, `doc` and `lib` outputs, thus,
`tinycc.out` may now only provide the tcc and cross compilers binaries.

- The `virtualisation.hypervGuest.videoMode` option has been removed. Standard tooling can now be used to configure display modes for Hyper-V VMs.

### Deprecations {#sec-nixpkgs-release-25.05-lib-deprecations}

`functor` is an implementation detail and should not be relied upon, but since its status wasn't clear and it has had some use cases without alternatives, changes are being handled as gracefully as possible. Deprecations within functor:
- `functor.wrapped` is now deprecated for some types and using it will give a warning with migration instructions. It is deprecated for these types:
    - `lib.types.attrsWith`
    - `lib.types.listOf`
