This release is the first PyO3 release to be dual-licensed under Apache 2.0 OR MIT licensing (expanding from just Apache 2.0 of previous releases).
Python 3.12 stable is now supported. The minimum supported Rust version has been increased to Rust 1.56.
The __eq__, __ne__, __lt__, __le__, __gt__ and __ge__ magic methods are now usable in #[pymethods] to implement Python operators as an alternative to the __richcmp__ method PyO3 already offered.
#[pyclass(rename_all = "renaming_rule")] has been added to rename all fields of structs exposed to Python (e.g. rename_all = "snake_case") .
PyDict::get_item now returns Result<Option<&PyAny>> instead of just Option<&PyAny>. The previous implementation which ignored Python errors used APIs now considered deprecated by the Python language designers; it is now considered best practice to bubble up any exception raised during dictionary __getitem__. For most users migration for this change will simply require addition of a ? on each use of PyDict::get_item.
Note that Python 3.7 is end of life but PyO3 will continue to support for now as a number of downstream Python packages still have high proportions of downloads on 3.7. A future release is expected to drop Python 3.7 when these numbers reduce.
There have been numerous other smaller improvements, changes and fixes. For full details see the CHANGELOG.
Thank you to everyone who contributed code, documentation, design ideas, bug reports, and feedback. The following users' commits are included in this release:
Add as_ptr and into_ptr inherent methods for Py, PyAny, PyRef, and PyRefMut. #3359
Implement DoubleEndedIterator for PyTupleIterator and PyListIterator. #3366
Add #[pyclass(rename_all = "...")] option: this allows renaming all getters and setters of a struct, or all variants of an enum. Available renaming rules are: "camelCase", "kebab-case", "lowercase", "PascalCase", "SCREAMING-KEBAB-CASE", "SCREAMING_SNAKE_CASE", "snake_case", "UPPERCASE". #3384
Add FFI definitions PyObject_GC_IsTracked and PyObject_GC_IsFinalized on Python 3.9 and up (PyPy 3.10 and up). #3403
Add types for None, Ellipsis, and NotImplemented. #3408
Add FFI definitions for the Py_mod_multiple_interpreters constant and its possible values. #3494
Add FFI definitions for PyInterpreterConfig struct, its constants and Py_NewInterpreterFromConfig. #3502
Changed
Change PySet::discard to return PyResult<bool> (previously returned nothing). #3281
Optimize implmentation of IntoPy for Rust tuples to Python tuples. #3321
Change PyDict::get_item to no longer suppress arbitrary exceptions (the return type is now PyResult<Option<&PyAny>> instead of Option<&PyAny>), and deprecate PyDict::get_item_with_error. #3330
Deprecate FFI definitions which are deprecated in Python 3.12. #3336
