PyO3 0.22.2

This release contains some minor reliability fixes building upon PyO3 0.22.1.

As PyO3 is still working on supporting freethreaded Python (upcoming in 3.13), support has been gated behind an UNSAFE_PYO3_BUILD_FREE_THREADED=1 environment variable to avoid unsuspecting users running into broken builds.

Packages built for the abi3 stable ABI will now use FFI functions for refcounting instead of inline reference count modifications on all versions of the stable ABI (previously only abi3 builds for 3.12 and up would use FFI functions). This helps mitigate interactions of old versions of the stable ABI with future CPython releases which do more complex reference counting (e.g. immortal objects, freethreaded reference counting).

The #[pymodule] declarative module now supports directly receiving options. (E.g. #[pymodule(name = "foo")], which would previously have been written as two attributes #[pymodule] #[pyo3(name = "foo")].)

A compile error on Rust 1.78 related to use of c"" literals has been fixed.

PyO3 0.22.1

This patch release improves some cases related to new functionality in PyO3 0.22.

PartialEq<bool> has been added for Bound<'py, PyBool>.

The #[pyo3(submodule)] attribute has been added for declarative modules to stop submodules from generating an external C symbol for importing the submodule directly (which is typically never used). Declarative modules will also now correctly add items annotated with full-path attributes like #[pyo3::prelude::pyfunction].

The #[pyclass(eq)] option will no longer raise a TypeError on comparison against types not in the signature.

A #[setter] in #[pymethods] with an Option<T> input will no longer raise a deprecation warning.

A regression has been fixed in conversions for 128-bit integers on big-endian platforms.

PyO3 0.22.0

This release introduces support for Python 3.13. Please note that Python 3.13 is still in beta, and while breaking changes are not expected it is very possible that code compiled against Python 3.13 beta versions will be incompatible with the final 3.13 release later in the year.

The minimum supported Rust version has been increased to Rust 1.63.

PyO3's deferred reference counting used to implement Clone for Py<T> without the global interpreter lock has been demonstrated to be impossible to implement safely in the general case and has consequently been changed to panic instead of deferring when cloning Py<T> without the GIL being held. Given the nature of panics inside Clone operations being a potential footgun, this implementation has been moved behind the opt-in py-clone feature.
