+## [0.23.4] - 2025-01-10
+
+### Added
+
+- Add `PyList::locked_for_each`, which uses a critical section to lock the list on the free-threaded build. [#4789](https://github.com/PyO3/pyo3/pull/4789)
+- Add `pyo3_build_config::add_python_framework_link_args` build script API to set rpath when using macOS system Python. [#4833](https://github.com/PyO3/pyo3/pull/4833)
+
+### Changed
+
+- Use `datetime.fold` to distinguish ambiguous datetimes when converting to and from `chrono::DateTime<Tz>` (rather than erroring). [#4791](https://github.com/PyO3/pyo3/pull/4791)
+- Optimize PyList iteration on the free-threaded build. [#4789](https://github.com/PyO3/pyo3/pull/4789)
+
+### Fixed
+
+- Fix unnecessary internal `py.allow_threads` GIL-switch when attempting to access contents of a `PyErr` which originated from Python (could lead to unintended deadlocks). [#4766](https://github.com/PyO3/pyo3/pull/4766)
+- Fix thread-unsafe access of dict internals in `BoundDictIterator` on the free-threaded build. [#4788](https://github.com/PyO3/pyo3/pull/4788)
+* Fix unnecessary critical sections in `BoundDictIterator` on the free-threaded build. [#4788](https://github.com/PyO3/pyo3/pull/4788)
+- Fix time-of-check to time-of-use issues with list iteration on the free-threaded build. [#4789](https://github.com/PyO3/pyo3/pull/4789)
+- Fix `chrono::DateTime<Tz>` to-Python conversion when `Tz` is `chrono_tz::Tz`. [#4790](https://github.com/PyO3/pyo3/pull/4790)
+- Fix `#[pyclass]` not being able to be named `Probe`. [#4794](https://github.com/PyO3/pyo3/pull/4794)
+- Fix not treating cross-compilation from x64 to aarch64 on Windows as a cross-compile. [#4800](https://github.com/PyO3/pyo3/pull/4800)
+- Fix missing struct fields on GraalPy when subclassing builtin classes. [#4802](https://github.com/PyO3/pyo3/pull/4802)
+- Fix generating import lib for PyPy when `abi3` feature is enabled. [#4806](https://github.com/PyO3/pyo3/pull/4806)
+- Fix generating import lib for python3.13t when `abi3` feature is enabled. [#4808](https://github.com/PyO3/pyo3/pull/4808)
+- Fix compile failure for raw identifiers like `r#box` in `derive(FromPyObject)`. [#4814](https://github.com/PyO3/pyo3/pull/4814)
+- Fix compile failure for `#[pyclass]` enum variants with more than 12 fields. [#4832](https://github.com/PyO3/pyo3/pull/4832)
