Release
sqlite-utils 4.0rc3 — Python CLI utility and library for manipulating SQLite databases
I hoped to release sqlite-utils 4.0 stable this weekend, but as I worked through the backlog of issues and PRs with a combination of Claude Fable 5 and GPT-5.5 the changelog since rc2 kept getting bigger.
The biggest new feature is support for introspecting and creating compound foreign keys - a feature that involves a subtle breaking change to table.foreign_keys and hence needed to land for the 4.0 stable release.
sqlite-utils also now follows SQLite's convention for case insensitive column names, which turned out to touch a bunch of different places at once.
