Fixed

• Fix memory leak in ArrayList by kngwyu #316

Fixed

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

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

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

Changes

• Replaced concat_idents with mashup

Changes

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

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

Changes

• Fix compatibility with TryFrom trait

Changes

• CPython 3.7 support

• Embedded CPython 3.7b1 crashes on initialization #110

• Allow to get mutable ref from PyObject #106

• Drop RefFromPyObject trait

• Add Python::register_any() method

• Fix impl FromPyObject for Py<T>

• Mark method that work with raw pointers as unsafe #95
