--------------
This version is the first full release for the Python v4 client and _requires_ weaviate versions >= 1.23.7.
Since the previous RC, there have been a number of improvements and final bug fixes.
- The type of ``object.vector`` has changed from ``Optional[Dict[str, List[float]]]`` to ``Dict[str, List[float]]`` so that ``object.vector`` is never ``None``.
- Exporting and importing of collections has been tidied up and improved.
- A number of methods have had input validation added to them.
- Most exceptions are now unified under a few common classes.
