+## [0.22.2] - 2024-07-17
+
+### Packaging
+
+- Require opt-in to freethreaded Python using the `UNSAFE_PYO3_BUILD_FREE_THREADED=1` environment variable (it is not yet supported by PyO3). [#4327](https://github.com/PyO3/pyo3/pull/4327)
+
+### Changed
+
+- Use FFI function calls for reference counting on all abi3 versions. [#4324](https://github.com/PyO3/pyo3/pull/4324)
+- `#[pymodule(...)]` now directly accepts all relevant `#[pyo3(...)]` options. [#4330](https://github.com/PyO3/pyo3/pull/4330)
+
+### Fixed
+
+- Fix compile failure in declarative `#[pymodule]` under presence of `#![no_implicit_prelude]`. [#4328](https://github.com/PyO3/pyo3/pull/4328)
+- Fix compile failure due to c-string literals on Rust < 1.79. [#4353](https://github.com/PyO3/pyo3/pull/4353)
