## Breaking Changes

The `params` and `searchParams` types in
`app/(payload)/admin/[[...segments]]/page.tsx` and
`app/(payload)/admin/[[...segments]]/not-found.tsx` must be changed to
promises:

```diff
- type Args = {
-   params: {
-     segments: string[]
-   }
-   searchParams: {
-     [key: string]: string | string[]
-   }
- }

+ type Args = {
+   params: Promise<{
+     segments: string[]
+   }>
+   searchParams: Promise<{
+     [key: string]: string | string[]
+   }>
+ }

```
