This is our first version that supports the stable Rust toolchain. The minimum required version is 1.39.0.
Thank you @davidhewitt @scalexm @tamuhey @konstin @Nateckert @Alexander-N @m-ou-se and all issue reporters 🙂

Maybe the most influential change is now #[pyclass] requires Send. Please see the migration guide for more.

Added

  • Support stable versions of Rust (>=1.39). #969
  • Add FFI definition PyObject_AsFileDescriptor. #938
  • Add PyByteArray::data, PyByteArray::as_bytes, and PyByteArray::as_bytes_mut. #967
  • Add GILOnceCell to use in situations where lazy_static or once_cell can deadlock. #975
  • Add Py::borrow, Py::borrow_mut, Py::try_borrow, and Py::try_borrow_mut for accessing #[pyclass] values. #976
  • Add IterNextOutput and IterANextOutput for returning from __next__ / __anext__. #997

Changed

  • Simplify internals of #[pyo3(get)] attribute. (Remove the hidden API GetPropertyValue.) #934
  • Call Py_Finalize at exit to flush buffers, etc. #943
  • Add type parameter to PyBuffer. #951
  • Require Send bound for #[pyclass]. #966
  • Add Python argument to most methods on PyObject and Py<T> to ensure GIL safety. #970
  • Change signature of PyTypeObject::type_object() - now takes Python argument and returns &PyType. #970
  • Change return type of PyTuple::slice() and PyTuple::split_from() from Py<PyTuple> to &PyTuple. #970
  • Change return type of PyTuple::as_slice to &[&PyAny]. #971
  • Rename PyTypeInfo::type_object to type_object_raw, and add Python argument. #975
  • Update num-complex optional dependendency from 0.2 to 0.3. #977
  • Update num-bigint optional dependendency from 0.2 to 0.3. #978
  • #[pyproto] is re-implemented without specialization. #961
  • PyClassAlloc::alloc is renamed to PyClassAlloc::new. #990
  • #[pyproto] methods can now have return value T or PyResult<T> (previously only PyResult<T> was supported). #996
  • #[pyproto] methods can now skip annotating the return type if it is (). #998

Removed

  • Remove ManagedPyRef (unused, and needs specialization) #930

Fixed

  • Fix passing explicit None to Option<T> argument #[pyfunction] with a default value. #936
  • Fix PyClass.__new__'s not respecting subclasses when inherited by a Python class. #990
  • Fix returning Option<T> from #[pyproto] methods. #996
  • Fix accepting PyRef<Self> and PyRefMut<Self> to #[getter] and #[setter] methods. #999
