 - `renovate` was updated to v41. See the upstream release notes for [v40](https://github.com/renovatebot/renovate/releases/tag/40.0.0) and [v41](https://github.com/renovatebot/renovate/releases/tag/41.0.0) for breaking changes.
 
+- The "NIXOS_EXTRA_MODULE_PATH" variable from configuration evaluation has been deprecated.
+  We recommend a workflow where you update the expression files instead, but if you wish to continue
+  to use this variable, you may do so with a module like:
+
+  ```nix
+  {
+    imports = [
+      (builtins.getEnv "NIXOS_EXTRA_MODULE_PATH")
+    ];
+  }
+  ```
+
+  This has the benefit that your configuration hints at the non-standard workflow.

 - `i18n.inputMethod.fcitx5.plasma6Support` has been removed because qt6 is the only one used for fcitx5-configtool now.
 
 - The `boot.readOnlyNixStore` has been removed. Control over bind mount options on `/nix/store` is now offered by the `boot.nixStoreMountOpts` option.
