-----

* New functions
* :func:`iter_index` (from the Python itertools docs)
* :func:`transpose` (from the Python itertools docs)
* :func:`matmul` (from the Python itertools docs)

* Other changes
* The ``batched`` function is marked as deprecated and will be removed in a future major release. For Python 3.12 and above, use ``itertools.batched`` instead. (thanks to neutrinoceros)
* The type hints now used postponed evaluation of annotations from PEP 563 (thanks to Isira-Seneviratne)
* Some documentation issues were fixed (thanks to Voskov and jdkandersson)

-----

* Potentially breaking changes
* :func:`grouper` no longer accepts an integer as its first argument. Previously this raised a ``DeprecationWarning``.
