 ## [Unreleased]
 
+## [0.3.1] - 2026-11-03
+
+### Changed
+- Each dialect's driver (`pg`, `mysql2`, `mssql`, `better-sqlite3`) is an optional peer dependency: you pass the driver object in, so npm no longer installs one you did not choose. A dialect works with any object offering the driver's API, the SQLite one with sql.js in a browser for example.
+- The docs use a to-do app as their example schema.
+
 ## [0.3.0] - 2026-11-02

 A procedure calls a database function at a path you choose. A `{name}` in the path passes that segment as the argument of the same name; the body's keys pass the others. Arguments are checked by name and type, and one with a default may be left out.
