-CHANGES FROM 1.1 TO 1.2, 10 March 2010
-
-* Switch to libevent.
-* Emulate the ri (reverse index) capability, ergo allowing tmux to at least
-  start on Sun consoles (TERM=sun, or sun-color).
-* Assign each entry a number, or lowercase letter in choose mode, and accept
-  that as a shortcut key.
-* Permit top-bit-set characters to be entered in the status line.
-* Mark no-prefix keys with (no prefix), rather than [] in list-keys.
-* New command show-messages (alias showmsgs), and new session option
-  message-limit, to show a per-client log of status lines messages up to the
-  number defined by message-limit.
-* Do not interpret #() for display-message to avoid leaking commands.
-* New window options window-status-format, and window-status-current-format to
-  control the format of each window in the status line.
-* Add a -p flag to display-message to print the output, instead of displaying
-  it in the status line.
-* Emulate il1, dl1, ich1 to run with vt100 feature set.
-* New command capture-pane (alias capturep) to copy the entire pane contents
-  to a paste buffer.
-* Avoid duplicating code by adding a -w flag to set-option, and show-options to
-  set, and show window options. The commands set-window-option, and
-  show-window-options are now aliases.
-* Panes can now be referred to as top, bottom, top-left, etc.
-* Add server-wide options, which can be set with set-option -s, and shown with
-  show-options -s.
-* New server option quiet (like -q from the command line).
-* New server option escape-time to set the timeout used to detect if escapes
-  are alone, part of a function key, or meta sequence.
-* New session options pane-active-border-bg, pane-active-border-fg,
-  pane-border-bg, and pane-border-fg to set pane colours.
-* Make split-window accept a pane target, instead of a window.
-* New command join-pane (alias joinp) to split, and move an existing pane into
-  the space (the opposite of break-pane), thus simplifying calls to
-  split-window, followed by move-window.
-* Permit S- prefix on keys for shift when the terminal/terminfo supports them.
-* Window targets (-t flag) can now refer to the last window (!), next (+), and
-  previous (-) window by number.
-* Mode keys to jump to the bottom/top of history, end of the next word, scroll
-  up/down, and reverse search in copy mode.
-* New session option display-panes-active-colour to display the active pane in
-  a different colour with the display-panes command.
-* Read the socket path from $TMUX if it's present, and -L, and -S are not
-  given.
-* Vi-style mode keys B, W, and E to navigate between words in copy mode.
-* Start in more mode when configuration file errors are detected.
-* Rectangle copy support added.
-* If attach-session was specified with the -r flag, make the client read-only.
-* Per-window alternate-screen option.
-* Make load-buffer work with FIFOs.
-* New window option word-separators to set the characters considered as word
-  separators in copy mode.
-* Permit keys in copy mode to be prefixed by a repeat count, entered with [1-9]
-  in vi mode, or M-[1-9] in emacs mode.
-* utf8 improvements.
-* As usual, additional code reduction, bug fixes, and manpage enhancements.
