Simon Willison has released version 4.0 of sqlite-utils, a Python library for interacting with SQLite databases. This update introduces significant new features including database schema migrations, nested transactions via a new `db.atomic()` method, and support for compound foreign keys. The migration system allows users to define a sequence of changes to a SQLite database schema in Python files, tracking applied migrations and applying pending ones. This feature is inspired by Django's migration system but is designed to be simpler for SQLite. AI
