On June 21 Simon Willison released sqlite-utils 4.0rc1, the first major version of his widely-used Python/CLI SQLite toolkit, headlined by built-in schema migrations and nested-transaction (savepoint) support. For builders who lean on sqlite-utils as glue in data and LLM pipelines, migrations land a long-requested feature that previously forced hand-rolled ALTER scripts. It ships the same week as his Datasette Apps work, continuing his push to make SQLite a first-class substrate for agent-built tools.
