Breaking changes

- SQLAlchemy: Upgraded to v2 (340)

Downstream packages will require SQLAlchemy v2 at a minimum.

Benefits in include: Built-in types for mypy, being able to use SQLAlchemy
core API against ORM entities.

Development

- Move from pytest's `tmp_dir` (`py.path.local`) to `tmp_path` (`pathlib.Path`),
346
- Remove unnecessary use of `typing_extension`'s `TypedDict` (346)

Note: `typing_extension`'s `TypedDict` is still
used for `NotRequired` `TypedDict`s until the minimum python version supports
them ([3.11](https://www.python.org/downloads/release/python-3110/) via [PEP-655](https://peps.python.org/pep-0655/))

Breaking changes

- **Python 3.7 Dropped**

Python 3.7 support has been dropped (343)

Its end-of-life is June 27th, 2023 and Python 3.8 will add support for
`typing.TypedDict` and `typing.Protocol` out of the box without needing
`typing_extensions`.

Development

- **Improved typings**

Move to strict mypy typings (324)

This will make future refactoring simplifications easier and maintain code
quality in the long term, in addition to more intelligent completions.
