Version 0.12 added support for the [online backup API](https://www.sqlite.org/backup.html). ### Added - Added support for the online backup API ([#47](https://github.com/zombiezen/go-sqlite/issues/47)). - Documented the `OpenFlags`. ### Changed - `OpenNoMutex` and `OpenFullMutex` no longer have an effect on `sqlite.OpenConn`. `OpenNoMutex` (i.e. [multi-thread mode](https://www.sqlite.org/threadsafe.html)) is now the only supported mode. `*sqlite.Conn` has never been safe to use concurrently from multiple goroutines, so this is mostly to prevent unnecessary locking and to avoid confusion.
