 - [sortingx-1.2.3](https://github.com/linjing-lab/sorting-algorithms/tree/v1.2.3) is the package that corrected the situation where elements are equal in `compare`, support more input data, like data as `[['Jack', (98, 100)], ['Bob', (98, 99)], ['Jessi', (98, 97)]]` and key as `lambda x: x[1][0]`.
 - [sortingx-1.3.0](https://github.com/linjing-lab/sorting-algorithms/tree/v1.3.0) is the final version that fully aligned with the `sorted`', reduces redundant data exchanging. like data as `[('Alex', 97, 90, 98, 95), ('Jack', 97, 88, 98, 92), ('Peter', 92, 95, 92, 96), ('Li', 97, 89, 98, 92)]` and key as `key=lambda x: x[1]`.
 - [sortingx-1.3.1](https://github.com/linjing-lab/sorting-algorithms/tree/v1.3.1) is the improved version from v1.3.0, and pre-operations from `_utils` are more conise to reduce shallow copy in Runtime.
+- [sortingx-1.3.2](https://github.com/linjing-lab/sorting-algorithms/tree/v1.3.2) is the optimized version from v1.3.1, and shrink the returns of calling intrinsic function named `__len__` to get length of `__iterable`.
