## Other changes

* Local conversation history and project code-search indexes now use RSQLite, replacing DuckDB. Persistent data is stored in btw's user cache and separated by project; install RSQLite to enable this storage.

* btw now requires ellmer (>= 0.4.2). The `set_model()` compatibility shim was removed, and `client_get_models()` now delegates to ellmer's `models_list()` generic, replacing a bespoke per-provider dispatch table (#214).

# btw 1.4.0
