# 2023-05-30
- Fix a strictness issue in `perInput`, affecting `inputs'`, `self'`.
This has caused infinite recursions and potentially performance issues since
the introduction of these module arguments.
# 2023-05-08
- Add [`importApply`](https://flake.parts/define-module-in-separate-file.html?highlight=importApply#importApply) for bringing variables from the flake scope into module files.
- Add `mkDeferredModuleOption` as a generic name for the implementation of `mkPerSystemOption`.
# 2023-03-26
- Add preliminary support for `disabledModules` for modules exposed via the importable `flakeModules` module.
This requires a Nixpkgs of 2023-03-09 or newer.
# 2023-01-05
- Add importable `easyOverlay` module for defining an overlay "easily" by reusing `perSystem`.
This is not for consuming overlays.
# 2022-12-25
- Added a new `flake.flakeModules` option so a flake can expose a module
to be used in a downstream flake's flake-parts usage. `.flakeModule` is
now an alias for `.flakeModules.default`.
Option only available if `flake-parts.flakeModules.flakeModules` is imported.

# 2022-12-17
- The old syntax `mkFlake { inherit self; }` is now strongly discouraged in
favor of:
```nix
outputs = inputs@{ flake-parts, ... }:
flake-parts.lib.mkFlake { inherit inputs; } { /* module */ }
```
This fixes an infinite recursion that occurs with the old syntax when
using the `inputs` module argument in `imports`.
If you're under the impression that this already worked, that's probably
because you were using `inputs` from the lexical scope (ie directly from
the flake outputs function arguments), rather than in a separate module file.

# 2022-12-07
- 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](https://flake.parts/options/flake-parts.html#opt-flake)
allows any attribute to be set. This attribute and related attributes should
be added to the nix-darwin project instead.

# 2022-10-11
- 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.
2022-10-11 18:20:13 +00:00
- The templates now use the default, _fixed_ `nixpkgs?dir=lib` dependency instead
of a _following_ `nixpkgs` dependency.

# 2022-05-25
- `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.
```diff
-perSystem = system: { config, lib, ... }:
+perSystem = { config, lib, system, ... }:
```
All `perSystem` option declarations must now use `flake-parts-lib.mkPerSystemOption`.
```nix
{
options.perSystem = mkPerSystemOption ({ config, ... }: {
options = {
# ...
};
# ...
});
}
```
- `flake-modules-core` is now called `flake-parts`.
- `flake.overlay` has been removed in favor of `flake.overlays.default`.
