    Planning for V11

    About V11 release If around July 1 I install the then current snapshot, will I have to do a full reinstall when the official V11 release is announced? In other words, will an upgrade option be offered? If it is offered, would you recommend a full install anyway? I am new to FreeBSD. Thanks...
