What's New in SQLAlchemy 2.0?
Posted byon under
You may have heard that a major version of SQLAlchemy, version 2.0, has been released in January 2023. Or maybe you missed the announcement and this is news to you. Either way, I thought you'd be curious to know what's new in it, if it is worth upgrading and how difficult the upgrade is.
As with previous software reviews, this is going to be an opinionated overview. I have been using the SQLAlchemy ORM in web projects for a long time, so in this article I will discuss the features that affect my own work, both in positive or negative ways. If instead you are interested to see a list of every change that went into this new release, then the official change log is the place to go.
