- `PyErr::new_type` now takes an optional docstring and now returns `PyResult<Py<PyType>>` rather than a `ffi::PyTypeObject` pointer. [#2027](https://github.com/PyO3/pyo3/pull/2027)
- Deprecate `PyType::is_instance`; it is inconsistent with other `is_instance` methods in PyO3. Instead of `typ.is_instance(obj)`, use `obj.is_instance(typ)`. [#2031](https://github.com/PyO3/pyo3/pull/2031)
- `PyErr::new_type` now takes an optional docstring and now returns `PyResult<Py<PyType>>` rather than a `ffi::PyTypeObject` pointer.
- The `create_exception!` macro can now take an optional docstring. This docstring, if supplied, is visible to users (with `.__doc__` and `help()`) and
accompanies your error type in your crate's documentation.
- `__getitem__`, `__setitem__` and `__delitem__` in `#[pymethods]` now implement both a Python mapping and sequence by default. [#2065](https://github.com/PyO3/pyo3/pull/2065)

- `PyDateTimeAPI` does not implicitly call `PyDateTime_IMPORT` anymore to reflect the original Python API more closely. Before the first call to `PyDateTime_IMPORT` a null pointer is returned. Therefore before calling any of the following FFI functions `PyDateTime_IMPORT` must be called to avoid undefined behaviour: [#2126](https://github.com/PyO3/pyo3/pull/2126)
