  - Supervisorctl now supports persistent readline history.  To
    enable, add "history_file = <pathname>" to the '[supervisorctl']
    section in your supervisord.conf file.

  - Multiple commands may now be issued on one supervisorctl command
    line, e.g. "restart prog; tail -f prog".  Separate commands with a
    single semicolon; they will be executed in order as you would
    expect.
