+## 3.35.9
+**`(fix):`** Fix generated error classes to correctly set the prototype chain, capture stack traces, and set the error name so `instanceof` checks behave as expected.
+Error classes now use `new.target.prototype` instead of the static class name for `Object.setPrototypeOf`,
+conditionally call `Error.captureStackTrace` for V8 environments, and set `this.name` dynamically.
