SQLAlchemy is a Python SQL toolkit and database object mapping (ORM) framework. It contains a complete set of enterprise-level persistence patterns designed for efficient and high-performance database access.

The release announcement reads that SQLAlchemy 2.0.0rc3 contains a small number of relatively minor feature enhancements and bug fixes, as well as testing as an update to the wheel builder plugin on Pypi. Applications that have not been tested in the 2.0 series should ensure that they have identified their requirements, as pip install will start fetching the 2.0 series by default instead of 1.4 when released.

2.0 aims toAdapted to practical use in modern Python, the development team spent more than three years upgrading the SQLAlchemy use-case model and architecture. They say that since the first release of SQLAlchemy in 2006, three major Python paradigms have emerged: Python 3, pep-484 type support, and asyncio. The 2.0 update of SQLAlchemy is precisely to adapt to the constant changes in the Python community. And the Python community is larger than it was 16 years ago, with more new developers who have higher standards for rigor, ease of use, and documentation.

According to the plan, SQLAlchemy 2.0 will release the final official version as soon as next week.
