+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.
+
+CHANGES FROM 1.4 TO 1.5, 09 July 2011
+
+* Support xterm mouse modes 1002 and 1003.
+* Change from a per-session stack of buffers to one global stack. This renders
+  copy-buffer useless and makes buffer-limit now a server option.
+* Fix most-recently-used choice by avoiding reset the activity timer for
+  unattached sessions every second.
+* Add a -P option to new-window and split-window to print the new window or
+  pane index in target form (useful to pass it into other commands).
+* Handle a # at the end of a replacement string (such as status-left)
+  correctly.
+* Support for UTF-8 mouse input (\033[1005h) which was added in xterm 262.
+  If the new mouse-utf8 option is on, UTF-8 mouse input is enabled for all
+  UTF-8 terminals. The option defaults to on if LANG etc are set in the same
+  manner as the utf8 option.
+* Support for HP-UX.
+* Accept colours of the hex form #ffffff and translate to the nearest from the
+  xterm(1) 256-colour set.
+* Clear the non-blocking IO flag (O_NONBLOCK) on the stdio file descriptors
+  before closing them (fixes things like "tmux ls && cat").
+* Use TMPDIR if set.
+* Fix next and previous session functions to actually work.
+* Support -x and -y for new-session to specify the initial size of the window
+  if created detached with -d.
+* Make bind-key accept characters with the top-bit-set and print them as octal.
+* Set $TMUX without the session when background jobs are run.
+* Simplify the way jobs work and drop the persist type, so all jobs are
+  fire-and-forget.
+* Accept tcgetattr/tcsetattr(3) failure, fixes problems with fatal() if the
+  terminal disappears while locked.
+* Add a -P option to detach to HUP the client's parent process (usually causing
+  it to exit as well).
+* Support passing through escape sequences to the underlying terminal by using
+  DCS with a "tmux;" prefix.
+* Prevent tiled producing a corrupt layout when only one column is needed.
+* Give each pane created in a tmux server a unique id (starting from 0), put it
+  in the TMUX_PANE environment variable and accept it as a target.
+* Allow a start and end line to be specified for capture-pane which may be
+  negative to capture part of the history.
+* Add -a and -s options to lsp to list all panes in the server or session
+  respectively. Likewise add -s to lsw.
+* Change -t on display-message to be target-pane for the #[A-Z] replacements
+  and add -c as target-client.
+* The attach-session command now prefers the most recently used unattached
+  session.
+* Add -s option to detach-client to detach all clients attached to a session.
+* Add -t to list-clients.
+* Change window with mouse wheel over status line if mouse-select-window is on.
+* When mode-mouse is on, automatically enter copy mode when the mouse is
+  dragged or the mouse wheel is used. Also exit copy mode when the mouse wheel
+  is scrolled off the bottom.
+* Provide #h character pair for short hostname (no domain).
+* Don't use strnvis(3) for the title as it breaks UTF-8.
+* Use the tsl and fsl terminfo(5) capabilities to update terminal title and
+  automatically fill them in on terminals with the XT capability (which means
+  their title setting is xterm-compatible).
+* Add a new option, mouse-resize-pane. When on, panes may be resized by
+  dragging their borders.
+* Fix crash by resetting last pane on {break,swap}-pane across windows.
+* Add three new copy-mode commands - select-line, copy-line, copy-end-of-line.
+* Support setting the xterm clipboard when copying from copy mode using the
+  xterm escape sequence for the purpose (if xterm is configured to allow it).
+* Support xterm(1) cursor colour change sequences through terminfo(5) Cc
+  (set) and Cr (reset) extensions.
+* Support DECSCUSR sequence to set the cursor style with two new terminfo(5)
+  extensions, Cs and Csr.
+* Make the command-prompt custom prompts recognize the status-left option
+  character pairs.
+* Add a respawn-pane command.
+* Add a couple of extra xterm-style keys that gnome terminal provides.
+* Allow the initial context on prompts to be set with the new -I option to
+  command-prompt. Include the current window and session name in the prompt
+  when renaming and add a new key binding ($) for rename session.
+* Option bell-on-alert added to trigger the terminal bell when there is an
+  alert.
+* Change the list-keys format so that it shows the keys using actual tmux
+  commands which should be able to be directly copied into the config file.
+* Show full targets for lsp/lsw -a.
+* Make confirm-before prompt customizable with -p option like command-prompt
+  and add the character pairs #W and #P to the default kill-{pane,window}
+  prompts.
+* Avoid sending data to suspended/locked clients.
+* Small memory leaks in error paths plugged.
+* Vi mode improvements.

+* vim displays reverse video instead of italics, while less displays italics
+  (or just regular text) instead of reverse. What's wrong?
+
+Screen's terminfo description lacks italics mode and has standout mode in its
+place, but using the same escape sequence that urxvt uses for italics. This
+means applications (like vim) looking for italics will not find it and might
+turn to reverse in its place, while applications (like less) asking for
+standout will end up with italics instead of reverse. To make applications
+aware that tmux supports italics and to use a proper escape sequence for
+standout, you'll need to create a new terminfo file with modified sgr, smso,
+rmso, sitm and ritm entries:
+
+	$ mkdir $HOME/.terminfo/
+	$ screen_terminfo="screen"
+	$ infocmp "$screen_terminfo" | sed \
+	  -e 's/^screen[^|]*|[^,]*,/screen-it|screen with italics support,/' \
+	  -e 's/%?%p1%t;3%/%?%p1%t;7%/' \
+	  -e 's/smso=[^,]*,/smso=\\E[7m,/' \
+	  -e 's/rmso=[^,]*,/rmso=\\E[27m,/' \
+	  -e '$s/$/ sitm=\\E[3m, ritm=\\E[23m,/' > /tmp/screen.terminfo
+	$ tic /tmp/screen.terminfo
+
+And tell tmux to use it in ~/.tmux.conf:
+	
+	set -g default-terminal "screen-it"
+
+If your terminal supports 256 colors, use:
+
+	$ screen_terminfo="screen-256color"
+
+instead of "screen". See the FAQ entry about 256 colors support for more info.
+Also note that tmux will still display reverse video on terminals that do not
+support italics.
+
+If your urxvt cannot display italics at all, make sure you have an italics
+capable font enabled, for example, add to ~/.Xdefaults:
+
+	urxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
