CHANGES FROM 1.5 TO 1.6, 23 January 2012

* Extend the mode-mouse option to add a third choice which means the mouse
  does not enter copy mode.
* Add a -r flag to switch-client to toggle the client read-only flag.
* Add pane-base-index option.
* Support \ for line continuation in the configuration file.
* Framework for more powerful formatting of command output and use it for
  list-{panes,windows,sessions}. This allows more descriptive replacements
  (such as #{session_name}) and conditionals.
* Mark dead panes with some text saying they are dead.
* Reject $SHELL if it is not a full path.
* Add -S option to refresh-client to redraw status line.
* Add an else clause for if-shell.
* Try to resolve relative paths for loadb and saveb (first, using client
  working directory, if any, then default-path or session working directory).
* Support for \e[3J to clear the history and send the corresponding
  terminfo code (E3) before locking.
* When in copy mode, make repeat count indicate buffer to replace, if used.
* Add screen*:XT to terminal-overrides for tmux-in-tmux.
* Status-line message attributes added.
* Move word-separators to be a session rather than window option.
* Change the way the working directory for new processes is discovered. If
  default-path isn't empty, it is used. Otherwise, if a new window is created
  from the command-line, the working directory of the client is used. If not,
  platform specific code is used to retrieve the current working directory
  of the process in the active pane. If that fails, the directory where the
  session was created is used, instead.
* Do not change the current pane if both mouse-select-{pane,window} are
  enabled.
* Add \033[s and \033[u to save and restore cursor position.
* Allow $HOME to be used as default-path.
* Add CNL and CPL escape sequences.
* Calculate last position correctly for UTF-8 wide characters.
* Add an option allow-rename to disable the window rename escape sequence.
* Attributes for each type of status-line alert (ie bell, content and
  activity) added. Therefore, remove the superfluous options
  window-status-alert-{attr,bg,fg}.
* Add a -R flag to send-keys to reset the terminal.
* Add strings to allow the aixterm bright colours to be used when
  configuring colours.
* Drop the ability to have a list of keys in the prefix in favour of two
  separate options, prefix and prefix2.
* Flag -2 added to send-prefix to send the secondary prefix key.
* Show pane size in top right of display panes mode.
* Some memory leaks plugged.
* More command-prompt editing improvements.
* Various manpage improvements.
* More Vi mode improvements.
