Changelog

Sourced from pyo3's changelog.

[0.27.1] - 2025-10-21

Fixed

• Fix clippy:declare_interior_mutable_const warning from #[pyfunction]. #5538
• Expose pyo3::types::PySendResult in public API. #5539

[0.27.0] - 2025-10-19

Packaging

• Extend range of supported versions of hashbrown optional dependency to include version 0.16. #5428
• Bump optional num-bigint dependency minimum version to 0.4.4. #5471
• Test against Python 3.14 final release. #5499
• Drop support for PyPy 3.9 and 3.10. #5516
• Provide a better error message when building an outdated PyO3 for a too-new Python version. #5519

Added

• Add FromPyObjectOwned as convenient trait bound for FromPyObject when the data is not borrowed from Python. #4390
• Add Borrowed::extract, same as PyAnyMethods::extract, but does not restrict the lifetime by deref. #4390
• experimental-inspect: basic support for #[derive(IntoPyObject)] (no struct fields support yet). #5365
• experimental-inspect: support #[pyo3(get, set)] and #[pyclass(get_all, set_all)]. #5370
• Add PyTypeCheck::classinfo_object that returns an object that can be used as parameter in isinstance or issubclass. #5387
• Implement PyTypeInfo on datetime.* types even when the limited API is enabled. #5388
• Implement PyTypeInfo on PyIterator, PyMapping and PySequence. #5402
• Implement PyTypeInfo on PyCode when using the stable ABI. #5403
• Implement PyTypeInfo on PyWeakrefReference when using the stable ABI. #5404
• Add pyo3::sync::RwLockExt trait, analogous to pyo3::sync::MutexExt for readwrite locks. #5435
• Add PyString::from_bytes. #5437
• Implement AsRef<[u8]> for PyBytes. #5445
• Add CastError and CastIntoError. #5468
• Add PyCapsuleMethods::pointer_checked and PyCapsuleMethods::is_valid_checked. #5474
• Add Borrowed::cast, Borrowed::cast_exact and Borrowed::cast_unchecked. #5475
• Add conversions for jiff::civil::ISOWeekDate. #5478
• Add conversions for &Cstr, Cstring and Cow<Cstr>. #5482
• add #[pyclass(skip_from_py_object)] option, to opt-out of the FromPyObject: PyClass + Clone blanket impl. #5488
• Add PyErr::add_note. #5489
• Add FromPyObject impl for Cow<Path> & Cow<OsStr>. #5497
• Add #[pyclass(from_py_object)] pyclass option, to opt-in to the extraction of pyclasses by value (requires Clone). #5506

Changed

• Rework FromPyObject trait for flexibility and performance: #4390
  • Add a second lifetime to FromPyObject, to allow borrowing data from Python objects (e.g. &str from Python str).
  • Replace extract_bound with extract, which takes Borrowed<'a, 'py, PyAny>.
• Optimize FromPyObject implementations for Vec<u8> and [u8; N] from bytes and bytearray. #5244
• Deprecate #[pyfn] attribute. #5384
• Fetch type name dynamically on cast errors instead of using PyTypeCheck::NAME. #5387
• Deprecate PyTypeCheck::NAME in favour of PyTypeCheck::classinfo_object which provides the type information at runtime. #5387
