   `future_into_py` functions now require future return type to be `Send`.
   [#60](https://github.com/PyO3/pyo3-async-runtimes/pull/60)
 - Change pyo3 `downcast` calls to `cast` calls [#65](https://github.com/PyO3/pyo3-async-runtimes/pull/65)
+- Use `pyo3::intern!` for method calls and `getattr` calls [#66](https://github.com/PyO3/pyo3-async-runtimes/pull/66)
