byobu (5.38-0ubuntu1) saucy; urgency=low

  [ Dustin Kirkland ]
  * usr/bin/byobu-janitor: LP: #1173620
    - there is no "grey" in tmux
  * usr/bin/byobu-launch:
    - append, rather than prepend, $PROMPT_COMMAND, as double-semi-colons
      are illegal, thanks to Christian Mäder in github for patch
  * usr/bin/byobu, usr/lib/byobu/include/Makefile.am,
    usr/lib/byobu/include/tmux-detach-all-but-current-client,
    usr/share/byobu/keybindings/f-keys.tmux,
    usr/share/byobu/keybindings/f-keys.tmux.disable,
    usr/share/doc/byobu/help.tmux.txt: LP: #939870
    - add a new keybinding, Alt-F6, which detaches all other clients
      + often used to maximize your tmux session, since tmux reduces
        the available size of your terminal to the smallest connected
        session
  * usr/bin/byobu: LP: #1176956
    - handle unlimted ulimits
  * usr/share/man/man1/byobu.1: LP: #1121414
    - document PuTTY UTF-8 configuration
      + thanks to Chris Holmes
  * usr/bin/byobu-keybindings, usr/bin/Makefile.am,
    usr/share/man/man1/byobu-keybindings.1,
    usr/share/man/man1/Makefile.am: LP: #1118755
    - added a new executable and manpage: byobu-keybindings
    - this is a command line utility for toggling Byobu's keybindings
      on an off
    - useful when Shift-F12 is not usable (Linux console tty), and
      when ctrl-a-! is not usable (tmux)
  * usr/bin/byobu-ctrl-a: LP: #1045070
    - check if the user has already chosen an escape sequence and if so,
      don't bother them with the ctrl-a question

  * usr/bin/byobu-reconnect-sockets, usr/lib/byobu/include/shutil: LP: #1162432
    - fix reconnect on zsh
