I'm getting the following error:


ken@ken-Presario-CQ57-Notebook-PC:~$ notmuch new
Error: Notmuch database at /home/ken/Mail/.notmuch
        has a newer database format version (3) than supported by this
        version of notmuch (1). Refusing to open this database in
        read-write mode.

Can anyone help me fix this?
