release
sqlite-utils 4.0rc3
For developers building AI workflows that rely on SQLite, compound foreign keys and consistent case handling improve schema management and reduce potential bugs when migrating databases.
What happened
Simon Willison has released sqlite-utils 4.0rc3, an update he had hoped would be the stable 4.0 release. However, as he worked through outstanding issues and pull requests—assisted by Claude and GPT models—the changelog grew. The most significant addition is support for introspecting and creating compound foreign keys. This introduces a subtle breaking change to the `table.foreign_keys` property, meaning the API now differs from rc2. Additionally, sqlite-utils now follows SQLite's convention for case-insensitive column names, a change that affected multiple parts of the codebase. Willison expects to gather feedback before finalizing the stable release.
Key takeaways
- sqlite-utils 4.0rc3 adds support for compound foreign keys (multiple columns).
- This introduces a breaking change to the `table.foreign_keys` property.
- Case-insensitive column names now follow SQLite's default behavior.
- The release was delayed because more changes accumulated during development.
- Willison used Claude and GPT models to help manage the backlog of issues.
