 # Changelog
 
+## 0.5.3
+
+- Bumped `Version::API_SPEC_VERSION` to the Apify OpenAPI spec `v2-2026-08-27T071624Z`. Covers the
+  removal of `pricingInfos` from the Create Actor request body (never implemented by this client),
+  the `RequestWithoutId`/`RequestBase` bundling fix (this client already enforces the `uniqueKey`/
+  `url` requirement client-side), and additive error-response/enum/format documentation fixes
+  (nullable `notice`, unformatted `pictureUrl`, `401` on `GET /v2/users/{userId}`, a new `ErrorType`
+  member, `409` on `PUT /v2/schedules/{scheduleId}`). None of this client's typed models expose
+  those fields or enums, so no client code or public interface change.
+
