Where does OmniFocus 2 keep the database file?

The database file seems to no longer live in the Library folder. Do you know where it resides in OF 2 so I can delete it?

The database file now is in a sandboxed container. The easiest way to get to the file is by opening the backup folder through ‘File’ → ‘Show Backups…’. The data file is in the same folder as the Backups folder.
