Release notes

Sourced from pyo3's releases.

PyO3 0.28.3

This patch contains several fixes for stability of the PyO3 0.28.x series:

Python::attach and Python::try_attach will no longer return before the thread initializing the interpreter has finished runnning site.py when using the auto-initialize feature.

Fix unsoundness in PyBytesWriter::write_vectored when targeting the Python 3.15 prerelease interpreter.

Fix possible deadlock in .into_pyobject() implementation for C-like #[pyclass] enums.

A couple of edge cases causing compile failures were also fixed.

Thank you to the following contributors for the improvements:

@alex @bschoenmaeckers @chirizxc @davidhewitt @Embers-of-the-Fire @Icxolu @maurosilber @ngoldbaum
