Hi From CodeSolid!
I realize it’s been a while; I just got back from a lovely vacation in Colombia. I realize you’re not hanging on my every word, but let me nevertheless tender a self-serving “Sorry for the delay.” Here’s the latest from CodeSolid and around the web.

SQLAlchemy Dataclass Example
The recent release of SQLAlchemy 2.0 included improved support for mapping database entities as Python dataclasses.
