 # zod-openapi
 
+## 5.2.0
+
+### Minor Changes
+
+- [#480](https://github.com/samchungy/zod-openapi/pull/480) [`5c3f98a`](https://github.com/samchungy/zod-openapi/commit/5c3f98a49a4377819b93993fb92a84510f794d28) Thanks [@samchungy](https://github.com/samchungy)! - Change `ZodUndefined` behaviour
+
+  This restores how `z.undefined()` is rendered to pre Zod v3.25.75.
+
+  It is now rendered as:
+
+  ```json
+  {
+    "not": {}
+  }
+  ```
+
+  If you want to override this behaviour you can customise this with the `override` function passed into the `createDocument` function.
+
+  eg.
+
+  ```ts
+  import { createDocument } from 'zod-openapi';
+
+  createDocument(
+    z.object({
+      name: z.undefined().optional(),
+    }),
+    {
+      override: (ctx) => {
+        if (ctx.zodSchema._zod.def.type === 'undefined') {
+          // This will change the behaviour back to throwing an error
+          delete ctx.jsonSchema.not;
+        }
+      },
+    },
+  );
+  ```
