+## [0.20.3] - 2024-02-23
+
+### Packaging
+
+- Add `portable-atomic` dependency. [#3619](https://github.com/PyO3/pyo3/pull/3619)
+- Check maximum version of Python at build time and for versions not yet supported require opt-in to the `abi3` stable ABI by the environment variable `PYO3_USE_ABI3_FORWARD_COMPATIBILITY=1`. [#3821](https://github.com/PyO3/pyo3/pull/3821)
+
+### Fixed
+
+- Use `portable-atomic` to support platforms without 64-bit atomics. [#3619](https://github.com/PyO3/pyo3/pull/3619)
+- Fix compilation failure with `either` feature enabled without `experimental-inspect` enabled. [#3834](https://github.com/PyO3/pyo3/pull/3834)
