• The darwinModules option has been removed. This was added in the early days without full consideration. The removal will have no effect on most flakes considering that the flake option allows any attribute to be set. This attribute and related attributes should be added to the nix-darwin project instead.

• The nixpkgs input has been renamed to nixpkgs-lib to signify that the only dependency is on the lib attribute, which can be provided by either the nixpkgs?dir=lib subflake or by the nixpkgs flake itself.

• The templates now use the default, fixed nixpkgs?dir=lib dependency instead of a following nixpkgs dependency.

• perSystem is not a functionTo submodule anymore, but a deferredModule, which is a lot like a regular submodule, but possible to invoke multiple times, for each system.

  All perSystem value definitions must remove the system: argument. If you need system to be in scope, use the one in the module arguments.

  -perSystem = system: { config, lib, ... }:
  +perSystem = { config, lib, system, ... }:
  

  All perSystem option declarations must now use flake-parts-lib.mkPerSystemOption.

  {
    options.perSystem = mkPerSystemOption ({ config, ... }: {
      options = {
        # ...
      };
      # ...
    });
  }
  

• flake-modules-core is now called flake-parts.

• flake.overlay has been removed in favor of flake.overlays.default.
