PyO3 v0.5.2

Fixed

• Fix undeterministic segfaults when creating many objects by kngwyu in #281

PyO3 v0.5.1

yanked

PyO3 v0.5.0

Added

• #[pyclass] objects can now be returned from rust functions
• PyComplex by kngwyu in #226
• PyDict::from_sequence(), equivalent to dict([(key, val), ...])
• Bindings for the datetime standard library types: PyDate, PyTime, PyDateTime, PyTzInfo, PyDelta with associated ffi types, by pganssle #200.
• PyString, PyUnicode, and PyBytes now have an as_bytes() method that returns &[u8].
• PyObjectProtocol::get_type_ptr() by ijl in #242

Removed

• Removed most entries from the prelude. The new prelude is small and clear.
• Slowly removing specialization uses
• PyString, PyUnicode, and PyBytes no longer have a data() method
  (replaced by as_bytes()) and PyStringData has been removed.

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<&PyDict> 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
• Splitted PyTypeObject into PyTypeObject without the create method and PyTypeCreate with requires PyObjectAlloc<Self> + PyTypeInfo + Sized.
• Ran cargo edition --fix which prefixed path with crate:: for rust 2018
• Renamed async to pyasync as async will be a keyword in the 2018 edition.
• Starting to use NonNull<*mut PyObject> for Py and PyObject by ijl #260

Fixed

• Added an explanation that the GIL can temporarily be released even while holding a GILGuard.
• Lots of clippy errors
• Fix segfault on calling an unknown method on a PyObject
• Work around a bug in the rust compiler by kngwyu #252
• Fixed a segfault with subclassing pyo3 create classes and using __class__ by kngwyu #263

Removed

• The pyobject_extract macro

PyO3 v0.5.0-alpha.2

v0.5.0-alpha.2

PyO3 v0.4.1

Fixed

• Fixed compilation on nightly since use_extern_macros was stabilized

Changed

• PyTryFrom's error is always to PyDowncastError

Removed

• The pyobject_downcast macro

PyO3 0.4.0

Removed

• Conversions from tuples to PyDict due to rust-lang/rust#52050

Changed

• Merged both examples into one
• Rustfmt all the things ✔️
• Switched to Keep a Changelog

PyO3 0.3.2

Changes

• Replaced concat_idents with mashup

PyO3 0.3.1

Changes

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

PyO3 0.3.0

Changes

• Upgraded to syn 0.14 which means much better error messages 🎉
• 128 bit integer support by kngwyu (#137)
• proc_macro has been stabilized on nightly (rust-lang/rust#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, #186)
• Always clone in getters. This allows using the get-annotation on all Clone-Types

PyO3 0.2.7

0.2.7 backports the compilation fix with current nightlies, so pyo3 stays usable until 0.3 is released.
