 ### Added
 - Add Rayon global thread pool control via `FEOS_MAX_THREADS` and `set_num_threads()`/ `get_num_threads()` to Python. [#346](https://github.com/feos-org/feos/pull/346)
 - Added DIPPR107 parameterization for ideal gas heat capacities of Burkhardt et al. [#344](https://github.com/feos-org/feos/pull/344)
+- Implemented `IdealGasAD<D>` for `Dippr`. [#357](https://github.com/feos-org/feos/pull/357)
 
 ### Fixed
 - Fixed the calculation of temperature and pressure derivatives of dew and bubble points. [#347](https://github.com/feos-org/feos/pull/347)
