+# 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`.
