# Changelog

## 0.3.1

* Fixed scoping bug in pyobject_native_type that would break rust-numpy

## 0.3.0

* Upgraded to syn 0.14 which means much better error messages :tada:
* 128 bit integer support by [kngwyu](https://github.com/kngwyu) ([#137](https://github.com/PyO3/pyo3/pull/173))
* `proc_macro` has been stabilized on nightly ([rust-lang/rust#52081](https://github.com/rust-lang/rust/pull/52081)). This means that we can remove the `proc_macro` feature, but now we need the `use_extern_macros` from the 2018 edition instead.
* All proc macro are now prefixed with `py` and live in the prelude. This means you can use `#[pyclass]`, `#[pymethods]`, `#[pyproto]`, `#[pyfunction]` and `#[pymodinit]` directly, at least after a `use pyo3::prelude::*`. They were also moved into a module called `proc_macro`. You shouldn't use `#[pyo3::proc_macro::pyclass]` or other longer paths in attributes because `proc_macro_path_invoc` isn't going to be stabilized soon.
* Renamed the `base` option in the `pyclass` macro to `extends`.
* `#[pymodinit]` uses the function name as module name, unless the name is overrriden with `#[pymodinit(name)]`
* The guide is now properly versioned.
* A few internal macros became part of the public api ([#155](https://github.com/PyO3/pyo3/pull/155), [#186](https://github.com/PyO3/pyo3/pull/186))
* Always clone in getters. This allows using the get-annotation on all Clone-Types
