# Version UPCOMING (TBD)
* Renamed `SqliteConnection` to `Connection`. The old name remains as a typealias.
* Adds a variety of `..._named` methods for executing queries using named placeholder parameters.
* Adds `backup` feature that exposes SQLite's online backup API.
* Adds `functions` feature that allows user-defined scalar functions to be added to
