    Hello.

    I am +1 to start wrapping up 3.0. I want to create some modeler
    documentation for the merge-stuff.

    I volunteered to join in on JPA, but lost motivation. At first it
    sounded like fun, but then I discovered that it was a lot of work ...
    and that I would probably not use it myself. I have a lot of respect
    for the work done and still think it is one of the most important
    things for cayenne after joining Apache.

    Regards,
    - Tore.
