Added
- Added new `HyerHyperDual` number for the calculation of third partial derivatives. [51](https://github.com/itt-ustutt/num-dual/pull/51)
- Added new functions `first_derivative`, `gradient`, `jacobian`, `second_derivative`, `hessian`, `third_derivative`, `second_partial_derivative`, `partial_hessian`, `third_partial_derivative` and `third_partial_derivative_vec` that provide a convenient interface for the calculation of derivatives. [52](https://github.com/itt-ustutt/num-dual/pull/52)
- Added new functions `try_first_derivative`, `try_gradient`, `try_jacobian`, `try_second_derivative`, `try_hessian`, `try_third_derivative`, `try_second_partial_derivative`, `try_partial_hessian`, `try_third_partial_derivative` and `try_third_partial_derivative_vec` that provide the same functionalities for fallible functions. [52](https://github.com/itt-ustutt/num-dual/pull/52)
- Implemented the `RealField` and `ComplexField` traits from `nalgebra` for `DualVec`. [59](https://github.com/itt-ustutt/num-dual/pull/59)
- Added the `python_macro` feature that provides the `impl_dual_num` macro. [63](https://github.com/itt-ustutt/num-dual/pull/63)
Changed
- Renamed `derive*` methods to `derivative*`. [52](https://github.com/itt-ustutt/num-dual/pull/52)
- Generalized the implementation of vector dual numbers to use both statically and dynamically sized arrays internally. [58](https://github.com/itt-ustutt/num-dual/pull/58)
- Removed `Copy`, `Send` and `Sync` as supertraits of `DualNum`. The individual dual number data types still implement the traits if they are statically allocated. [58](https://github.com/itt-ustutt/num-dual/pull/58)
- Renamed type aliases from, e.g., `DualVec` to `DualSVec` and `DualDVec` for statically and dynamically allocated dual numbers, respectively. [58](https://github.com/itt-ustutt/num-dual/pull/58)
Removed
- Removed the `StaticMat` struct in favor of the analogous implementations from `nalgebra`. [52](https://github.com/itt-ustutt/num-dual/pull/52)
- Removed the `derive*` methods for vector types due to the change to `nalgebra`. [52](https://github.com/itt-ustutt/num-dual/pull/52)
- Removed the `derive*` functions in Python in favor of the aforementioned new functions. [52](https://github.com/itt-ustutt/num-dual/pull/52)
- Removed the `build_wheel` workspace crate. The main crate is now also used to build the Python package. [63](https://github.com/itt-ustutt/num-dual/pull/63)
