# Changelog All notable changes to this project will be documented in this file. The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/) and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html). ## Unreleased ### Added * `#[pyclass]` objects can now be returned from rust functions * `PyComplex` by kngwyu in [#226](https://github.com/PyO3/pyo3/pull/226) ### Removed * Removed most entries from the prelude. The new prelude is small and clear. * Slowly removing specialization uses ### Changed * Removes the types from the root module and the prelude. They now live in `pyo3::types` instead. * All exceptions are consturcted with `py_err` instead of `new`, as they return `PyErr` and not `Self`. * `as_mut` and friends take and `&mut self` instead of `&self` * `ObjectProtocol::call` now takes an `Option` for the kwargs instead of an `IntoPyDictPointer`. * `IntoPyDictPointer` was replace by `IntoPyDict` which doesn't convert `PyDict` itself anymore and returns a `PyDict` instead of `*mut PyObject`. * `PyTuple::new` now takes an `IntoIterator` instead of a slice * Updated to syn 0.15 ### Fixed * Added an explenation that the GIL can temporarily be released even while holding a GILGuard. * Lots of clippy errors ### Removed * The pyobject_extract macro ## [0.4.1] - 2018-08-20 ### Fixed * Fixed compilation on nightly since `use_extern_macros` was stabilized ### Changed * PyTryFrom's error is always to `PyDowncastError` ### Removed * The pyobject_downcast macro ## [0.4.0] - 2018-07-30 ### Removed * Conversions from tuples to PyDict due to [rust-lang/rust#52050](https://github.com/rust-lang/rust/issues/52050) ### Changed * Merged both examples into one * Rustfmt all the things :heavy_check_mark: * Switched to [Keep a Changelog](http://keepachangelog.com/en/1.0.0/) ## [0.3.2] - 2018-07-22 ### Changed * Replaced `concat_idents` with mashup ## [0.3.1] - 2018-07-18 ### Fixed * Fixed scoping bug in pyobject_native_type that would break rust-numpy ## [0.3.0] - 2018-07-18 ### Changed * 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. ### Added * 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 ## [0.2.7] - 2018-05-18 ### Fixed * Fix nightly breakage with proc_macro_path ## [0.2.6] - 2018-04-03 ### Fixed * Fix compatibility with TryFrom trait #137 ## [0.2.5] - 2018-02-21 ### Added * CPython 3.7 support ### Fixed * Embedded CPython 3.7b1 crashes on initialization #110 * Generated extension functions are weakly typed #108 * call_method*() crashes when the method does not exist #113 * Allow importing exceptions from nested modules #116 ## [0.2.4] - 2018-01-19 ### Added * Allow to get mutable ref from PyObject #106 * Drop `RefFromPyObject` trait * Add Python::register_any() method ### Fixed * Fix impl `FromPyObject` for `Py` * Mark method that work with raw pointers as unsafe #95 ## [0.2.3] - 11-27-2017 ### Fixed * Proper `c_char` usage #93 ### Changed * Rustup to 1.23.0-nightly 2017-11-07 ### Removed * Remove use of now unneeded 'AsciiExt' trait ## [0.2.2] - 09-26-2017 ### Changed * Rustup to 1.22.0-nightly 2017-09-30 ## [0.2.1] - 09-26-2017 ### Fixed * Fix rustc const_fn nightly breakage ## [0.2.0] - 08-12-2017 ### Changed * Allow to add gc support without implementing PyGCProtocol #57 * Refactor `PyErr` implementation. Drop `py` parameter from constructor. ### Added * Added inheritance support #15 * Added weakref support #56 * Added subclass support #64 * Added `self.__dict__` supoort #68 * Added `pyo3::prelude` module #70 * Better `Iterator` support for PyTuple, PyList, PyDict #75 * Introduce IntoPyDictPointer similar to IntoPyTuple #69 ## 0.1.0 - 07-23-2017 ### Added * Initial release [0.4.1]: https://github.com/pyo3/pyo3/compare/v0.4.0...v0.4.1 [0.4.0]: https://github.com/pyo3/pyo3/compare/v0.3.2...v0.4.0 [0.3.2]: https://github.com/pyo3/pyo3/compare/v0.3.1...v0.3.2 [0.3.1]: https://github.com/pyo3/pyo3/compare/v0.3.0...v0.3.1 [0.3.0]: https://github.com/pyo3/pyo3/compare/v0.2.7...v0.3.0 [0.2.7]: https://github.com/pyo3/pyo3/compare/v0.2.6...v0.2.7 [0.2.6]: https://github.com/pyo3/pyo3/compare/v0.2.5...v0.2.6 [0.2.5]: https://github.com/pyo3/pyo3/compare/v0.2.4...v0.2.5 [0.2.4]: https://github.com/pyo3/pyo3/compare/v0.2.3...v0.2.4 [0.2.3]: https://github.com/pyo3/pyo3/compare/v0.2.2...v0.2.3 [0.2.2]: https://github.com/pyo3/pyo3/compare/v0.2.1...v0.2.2 [0.2.1]: https://github.com/pyo3/pyo3/compare/v0.2.0...v0.2.1 [0.2.0]: https://github.com/pyo3/pyo3/compare/v0.1.0...v0.2.0
