[dependabot]

Bumps pyo3 from 0.25.1 to 0.27.2.

Release notes

Sourced from pyo3's releases.

PyO3 0.27.2

This patch contains very minor fixes for the PyO3 0.27 series:

• Workaround a rustc 1.92+ crash compiling PyO3 with both debug assertions and optimizations enabled.
• Fix runtime crash when subclassing dicts on PyPy and GraalPy.

There are also a number of documentation improvements applied across the codebase.

Thank you to the following contributors for the improvements:

PyO3 0.27.1

This release fixes a clippy lint regression in PyO3 0.27.0, and exposes the PySendResult type (the return value from Bound<PyIterator>::send).

Thank you to the following contributors for the improvements:

PyO3 0.27.0

This release is the first PyO3 release to be tested against Python 3.14.0 final. There are no significant changes to 3.14 support since PyO3 0.26 which was tested against the 3.14 release candidates.

Support for PyPy 3.9 and PyPy 3.10 (both no longer supported upstream) has been dropped.

The FromPyObject trait has been reworked in a similar fashion to the IntoPyObject trait introduced in PyO3 0.23. This has established a performant and flexible implementation of both these traits and no further changes to the traits are anticipated in the future. Thank you for the patience upgrading through these incremental improvements at the core of PyO3.

The .downcast() family of functions are now deprecated in favour of the .cast() family of functions, which are an incremental improvement to API usability and to error messages on failed conversions.

Operations on the PyCapsule type have been changed without deprecation to fix some issues with lifetimes of return values (in .name() and .reference() specifically). The capsule API now also encourages checking of capsule names, which is one of the few defences available to protect the validity of casting data read by the capsule API.

There are also many other incremental improvements, bug fixes and smaller features.

Please consult the migration guide for help upgrading.

Thank you to everyone who contributed code, documentation, design ideas, bug reports, and feedback. The following contributors' commits are included in this release:
