• 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.
