+CHANGES FROM 1.7 to 1.8, 26 March 2013
+
+Incompatible Changes
+====================
+
+* layout redo/undo has been removed.
+
+Normal Changes
+==============
+
+* Add halfpage up/down bindings to copy mode.
+* Session choosing fixed to work with unattached sessions.
+* New window options window-status-last-{attr,bg,fg} to denote the last
+  window which was active.
+* Scrolling in copy-mode now scrolls the region without moving the mouse
+  cursor.
+* run-shell learnt '-t' to specify the pane to use when displaying output.
+* Support for middle-click pasting.
+* choose-tree learns '-u' to start uncollapsed.
+* select-window learnt '-T; to toggle to the last window if it's already
+  current.
+* New session option 'assume-paste-time' for pasting text versus key-binding
+  actions.
+* choose-* commands now work outside of an attached client.
+* Aliases are now shown for list-commands command.
+* Status learns about formats.
+* Free-form options can be set with set-option if prepended with an '@'
+  sign.
+* capture-pane learnt '-p' to send to stdout, and '-e' for capturing escape
+  sequences, and '-a' to capture the alternate screen, and '-P' to dump
+  pending output.
+* Many new formats added (client_session, client_last_session, etc.)
+* Control mode, which is a way for a client to send tmux commands.
+  Currently more useful to users of iterm2.
+* resize-pane learnt '-x' and '-y' for absolute pane sizing.
+* Config file loading now reports errors from all files which are loaded via
+  the 'source-file' command.
+* 'copy-pipe' mode command to copy selection and pipe the selection to a
+  command.
+* Changes panes can now emit focus notifications for certain applications
+  which use those.
+* run-shell and if-shell now accept format placeholders.
+* resize-pane learnt '-Z' for zooming a pane temporarily.
+* new-session learnt '-A' to make it behave like attach-session.
+* set-option learnt '-o' to prevent setting an option which is already set.
+* capture-pane and show-options learns '-q' to silence errors.
+* New command 'wait-for' which blocks a client until woken up again.
+* Resizing panes will now reflow the text inside them.
+* Lots and lots of bug fixes, fixing memory-leaks, etc.
+* Various manpage improvements.
+
+CHANGES FROM 1.6 to 1.7, 13 October 2012
+
+* tmux configuration files now support line-continuation with a "\" at the
+  end of a line.
+* New option status-position to move the status line to the top or bottom of
+  the screen.
+* Enforce history-limit option when clearing the screen.
+* Give each window a unique id, like panes but prefixed with @.
+* Add pane id to each pane in layout description (while still accepting
+  the old form).
+* Provide defined ways to set the various default-path possibilities: ~
+  for home directory, . for server start directory, - for session start
+  directory and empty for the pane's working directory (the default). All
+  can also be used as part of a relative path (eg -/foo). Also provide -c
+  flags to neww and splitw to override default-path setting.
+* Add -l flag to send-keys to send input literally (without translating
+  key names).
+* Allow a single option to be specified to show-options to show just that
+  option.
+* New command "move-pane" (like join-pane but allows the same window).
+* join-pane and move-pane commands learn "-b" option to place the pane to
+  the left or above.
+* Support for bracketed-paste mode.
+* Allow send-keys command to accept hex values.
+* Add locking around "start-server" to avoid race-conditions.
+* break-pane learns -P/-F arguments for display formatting.
+* set-option learns "-q" to make it quiet, and not print out anything.
+* copy mode learns "wrap-search" option.
+* Add a simple form of output rate limiting by counting the number of
+  certain C0 sequences (linefeeds, backspaces, carriage returns) and if it
+  exceeds a threshold (current default 250/millisecond), start to redraw
+  the pane every 100 milliseconds instead of making each change as it
+  comes. Two configuration options - c0-change-trigger and
+  c0-change-interval.
+* find-window learns new flags:  "-C", "-N", "-T" to match against either or
+  all of a window's content, name, or title.  Defaults to all three options
+  if none specified.
+* find-window automatically selects the appropriate pane for the found
+  matches.
+* show-environment can now accept one option to show that environment value.
+* Exit mouse mode when end-of-screen reached when scrolling with the mouse
+  wheel.
+* select-layout learns -u and -U for layout history stacks.
+* kill-window, detach-client, kill-session all  learn "-a" option for
+  killing all but the current thing specified.
+* move-window learns "-r" option to renumber window sequentially in a
+  session.
+* New session option "renumber-windows" to automatically renumber windows in
+  a session when a window is closed.  (see "move-window -r").
+* Only enter copy-mode on scroll up.
+* choose-* and list-* commands all use "-F" for format specifiers.
+* When spawning external commands, the value from the "default-shell" option
+  is now used, rather than assuming /bin/sh.
+* New choose-tree command to render window/sessions as a tree for selection.
+* display-message learns new format options.
+* For linked-windows across sessions, all flags for that window are now
+  cleared across sessions.
+* Lots and lots of bug fixes, fixing memory-leaks, etc.
+* Various manpage improvements.
+
+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.
+
+CHANGES FROM 1.3 TO 1.4, 27 December 2010
+
+* Window bell reporting fixed.
+* Show which pane is active in the list-panes output.
+* Backoff reworked.
+* Prevent the server from dying when switching into copy mode when already
+  in a different mode.
+* Reset running jobs when the status line is enabled or disabled.
+* Simplify xterm modifier detection.
+* Avoid crashing in copy mode if the screen size is too small for the
+  indicator.
+* Flags -n and -p added to switch-client.
+* Use UTF-8 line drawing characters on UTF-8 terminals, thus fixing some
+  terminals (eg putty) which disable the vt100 ACS mode switching sequences
+  in UTF-8 mode. On terminals without ACS, use ASCII equivalents.
+* New server option exit-unattached added.
+* New session option destroy-unattached added.
+* Fall back on normal session choice method if $TMUX exists but is invalid
+  rather than rejecting.
+* Mark repeating keys with "(repeat)" in the key list.
+* When removing a pane, don't change the active pane unless the active pane
+  is actually the one being removed.
+* New command last-pane added.
+* AIX fixes.
+* Flag -a added to unbind-key.
+* Add XAUTHORITY to update-environment.
+* More info regarding window and pane flags is now shown in list-*.
+* If VISUAL or EDITOR contains "vi" configure mode-keys and status-key to vi.
+* New window option monitor-silence and session option visual-silence added.
+* In the built-in layouts distribute the panes more evenly.
+* Set the default value of main-pane-width to 80 instead of 81.
+* Command-line flag -V added.
+* Instead of keeping a per-client prompt history make it global.
+* Fix rectangle copy to behave like emacs (the cursor is not part of the
+  selection on the right edge but on the left it is).
+* Flag -l added to switch-client.
+* Retrieve environment variables from the global environment rather than
+  getenv(3), thus allowing them to be updated during the configuration file.
+* New window options other-pane-{height,width} added.
+* More minor bugs fixed and manpage improvements.
+
+CHANGES FROM 1.2 TO 1.3, 18 July 2010
+
+* New input parser.
+* Flags to move through panes -UDLR added to select-pane.
+* Commands up-pane, and down-pane removed, since equivalent behaviour is now
+  available through the target flag (-t:+ and -t:-).
+* Jump-forward/backward in copy move (based on vi's F, and f commands).
+* Make paste-buffer accept a pane as a target.
+* Flag -a added to new-window to insert a window after an existing one, moving
+  windows up if necessary.
+* Merge more mode into copy mode.
+* Run job commands explicitly in the global environment (which can be modified
+  with setenv -g), rather than with the environment tmux started with.
+* Use the machine's hostname as the default title, instead of an empty string.
+* Prevent double free if the window option remain-on-exit is set. 
+* Key string conversions rewritten.
+* Mark zombie windows as dead in the choose-window list.
+* Tiled layout added.
+* Signal handling reworked.
+* Reset SIGCHLD after fork to fix problems with some shells.
+* Select-prompt command removed. Therefore, bound ' to command-prompt -p index
+  "select-window -t:%%" by default.
+* Catch SIGHUP and terminate if running as a client, thus avoiding clients from
+  being left hanging around when, for instance, a SSH session is disconnected.
+* Solaris 9 fixes (such as adding compat {get,set}env(3) code).
+* Accept none instead of default for attributes.
+* Window options window-status-alert-{alert,bg,fg} added.
+* Flag -s added to the paste-buffer command to specify a custom separator.
+* Allow dragging to make a selection in copy mode if the mode-mouse option is
+  set.
+* Support the mouse scroll wheel.
+* Make pipe-pane accept special character sequences (eg #I).
+* Fix problems with window sizing when starting tmux from .xinitrc.
+* Give tmux sockets (but not the containing folder) group permissions.
+* Extend the target flags (ie -t) to accept an offset (for example -t:+2), and
+  make it wrap windows, and panes.
+* New command choose-buffer added.
+* New server option detach-on-destroy to set what happens to a client when the
+  session it is attached to is destroyed. If on (default), the client is
+  detached. Otherwise, the client is switched to the most recently active of
+  the remaining sessions.
+* The commands load-buffer, and save-buffer now accept a dash (-) as the file
+  to read from stdin, or write to stdout.
+* Custom layouts added.
+* Additional code reduction, bug fixes, and manpage enhancements.

-* How is tmux different from GNU screen? What else does it offer?
+* How is tmux different from GNU screen?
 
-tmux offers several advantages over screen:
+tmux and GNU screen have many similarities. Some of the main differences I am
+aware of are (bearing in mind I haven't used screen for a few years now):
 
-- a clearly-defined client-server model: windows are independent entities which
+- tmux uses a client-server model. Each server has single Unix domain socket in
-  may be attached simultaneously to multiple sessions and viewed from multiple
+  /tmp and within one server there are multiple sessions which may be attached
-  clients (terminals), as well as moved freely between sessions within the same
+  to multiple clients (terminals).
-  tmux server;
-- a consistent, well-documented command interface, with the same syntax
-  whether used interactively, as a key binding, or from the shell;
-- easily scriptable from the shell;
-- multiple paste buffers;
-- choice of vi or emacs key layouts;
-- an option to limit the window size;
-- a more usable status line syntax, with the ability to display the first line
-  of output of a specific command;
-- a cleaner, modern, easily extended, BSD-licensed codebase.
 
-There are still a few features screen includes that tmux omits:
+  This has advantages, notably: windows may be linked simultaneously to
+  multiple sessions; windows may be moved freely between sessions; and a client
+  may be switched between sessions easily (C-b D). There is one major
+  disadvantage: if the server crashes, game over, all sessions die. In
+  practice, however, tmux is quite stable and gets more so as people report any
+  bugs they hit :-).
 
-- builtin serial and telnet support; this is bloat and is unlikely to be added
+  This model is different from screen, where typically each new screen instance
-  to tmux;
+  is independent. tmux supports the same behaviour by using multiple servers
-- wider platform support, for example IRIX and HP-UX, and for odd terminals.
+  with the -L option but it is not typically recommended.
+
+- Different command interfaces. One of the goals of tmux is that the shell
+  should be easily usable as a scripting language - almost all tmux commands
+  can be used from the shell and behave identically whether used from the
+  shell, from a key binding or from the command prompt. Personally I also find
+  tmux's command interface much more consistent and clearer, but this is
+  subjective.
+
+- tmux calls window names (what you see in the status line) "names", screen
+  calls them "titles".
+
+- tmux has a multiple paste buffers. Not a major one but comes in handy quite a
+  lot.
+
+- tmux supports automatically renaming windows to the running application
+  without gross hacks using escape sequences. Its even on by default.
+
+- tmux has a choice of vi or emacs key layouts. Again, not major, but I use
+  emacs so if tmux did support only one key set it would be emacs and then all
+  the vi users would get humpy. Key bindings may be completely reconfigured in
+  any case.
+
+- tmux has an option to limit the window size.
+
+- tmux has search in windows (C-b f).
+
+- The window split (pane) model is different. tmux has two objects, windows and
+  panes; screen has just windows. This difference has several implications:
+
+  * In screen you can have a window appear in several layouts, in tmux a pane
+  can only be in one window (fixing this is a big todo item but quite
+  invasive).
+
+  * tmux layouts are immutable and do not get changed unless you modify them.
+
+  * In tmux, all panes are closed when you kill a window.
+
+  * tmux panes do not have individual names, titles and so on.
+
+  I think tmux's model is much easier to manage and navigate within a window,
+  but breaking panes off from and joining them to windows is more clumsy.
+
+  tmux also has support for preset pane layouts.
+
+- tmux's status line syntax is more readable and easier to use. I think it'd be
+  hard for anyone to argue with this. tmux doesn't support running a command
+  constantly and always using the last line of its output, commands must be run
+  again each time.
+
+- tmux has modern, easily extended code. Again hard to argue screen is better
+  if you have looked at the code.
+
+- tmux depends on libevent. I don't see this as a disadvantage: libevent is
+  small and portable, and on modern systems with current package management
+  systems dependencies are not an issue. libevent brings advantages in code
+  simplicity and performance.
+
+- screen allows the window to be bigger than the terminal and can pan around
+  it. tmux limits the size to the largest attached client. This is a big todo
+  item for tmux but it is not trivial.
+
+- screen has builtin serial and telnet support; this is bloat and is unlikely
+  to be added to tmux.
+
+- screen has support for updating utmp. Nobody has really come up with a clean,
+  portable way to do this without making tmux setuid or setgid yet.
+
+- Environment handling is different.
+
+- tmux tends to be more demanding on the terminal so tends to show up terminal
+  and application bugs which screen does not.
+
+- screen has wider platform support, for example IRIX, and for odd terminals.

+* How can I blank the tmux window?
+
+GNU screen has a feature whereby it will blank the screen after a period of
+inactivity. To do the same thing in tmux, use the lock-command setting, for
+example (with GNU bash):
+
+set -g lock-command 'tput civis && read -s -n1'
+
+This will remove the cursor and tell the shell to quit once a key has been
+pressed. For zsh, use "read -s -k1".
+
+In addition, it's possible to have both blanking and locking (for instance via
+lock(1) or vlock(1)) by using the following:
+
+bind x set lock-command '/usr/bin/vlock' \; lock-client \; set lock-command 'tput civis && read -s -n1'
+
+* 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
+
+* How can I make tmux use my terminal's scrollback buffer?
+
+Normally, tmux enables the terminal's "alternate screen". Most terminals (such
+as xterm) do not save scrollback for the alternate screen. You might prefer
+tmux to use the normal screen, so it uses your terminal's scrollback
+buffer. This way, you can access the scrollback buffer as usual, for example
+using the mouse wheel - although there is no guarantee output inside tmux will
+always (or ever) be added to the scrollback.
+
+You can make tmux use the normal screen by telling it that your terminal does
+not have an alternate screen. Put the following in ~/.tmux.conf:
+
+        set -g terminal-overrides 'xterm*:smcup@:rmcup@'
+
+Adjust if your $TERM does not start with xterm.
+
+tmux will still emulate the alternate screen for applications run under tmux,
+so you don't really lose anything with this setting. The only disadvantage is
+that when you exit tmux, it will not restore whatever was there before you
+started.
+
+* How do I see the default configuration?
+
+Show the default session options by starting a new tmux server with no
+configuration file:
+
+        $ tmux -Lfoo -f/dev/null start\; show -g
+
+Or the default window options:
+
+        $ tmux -Lfoo -f/dev/null start\; show -gw

-Welcome to tmux!
-
-tmux is a "terminal multiplexer", it enables a number of terminals (or windows)
-to be accessed and controlled from a single terminal. tmux is intended to be a
-simple, modern, BSD-licensed alternative to programs such as GNU screen.
-
-This release runs on OpenBSD, FreeBSD, NetBSD, Linux and OS X and may still
-run on Solaris and AIX (although they haven't been tested in a while). It is
-usable, although there remain a number of missing features and some remaining
-bugs are expected.
-
-Since the 1.2 release that tmux depends on libevent. Download the stable
-version from:
-
-	http://www.monkey.org/~provos/libevent/
-
-tmux consists of a server part and multiple clients. The server is created when
-required and runs continuously unless killed by the user. Clients access the
-server through a socket in /tmp. Multiple sessions may be created on a single
-server and attached to a number of clients. Each session may then have a number
-of windows and windows may be linked to a number of sessions. Commands are
-available to create, rename and destroy windows and sessions; to attach and
-detach sessions from client terminals; to set configuration options; to split
-windows into several simultaneously displayed panes; and to bind and unbind
-command keys (invoked preceded by a prefix key, by default ctrl-b). Please see
-the tmux(1) man page for further information.
-
-The following is a summary of major features implemented in this version:
-
-- Basic multiplexing, window switching, attaching and detaching.
-- Window listing and renaming.
-- Key binding.
-- Handling of client terminal resize.
-- Terminal emulation sufficient to handle most curses applications.
-- A optional status line (enabled by default).
-- Window history and copy and paste.
-- Support for VT100 line drawing characters.
-- A large command set.
-- Vertical window splitting and layout.
-- Automatic server locking on inactivity by running an external command.
-- A configuration file.
-- UTF-8 support.
-
-A more extensive, but rough, todo list is included in the TODO file.
-
-tmux also depends on several features of the client terminal (TERM), if these
-are missing it may refuse to run, or not behave correctly.
-
-tmux supports UTF-8. To use it, the utf8 option must be set on each window;
-this may be turned on for all windows by setting it as a global option, see
-tmux(1) and the FAQ file. As of 0.9, tmux attempts to autodetect a
-UTF-8 capable terminal by checking the LC_ALL, LC_CTYPE and LANG environment
-variables. list-clients may be used to check if this is detected correctly; if
-not, the -u command-line flag may be specified.
-
-A Vim syntax file is available in the examples directory. To install it:
-
-- Drop the file in the syntax directory in your runtimepath (such as
-  ~/.vim/syntax/tmux.vim).
-- Make the filetype recognisable by adding the following to filetype.vim
-  in your runtimepath (~/.vim/filetype.vim):
-
-	augroup filetypedetect
-		au BufNewFile,BufRead .tmux.conf*,tmux.conf* setf tmux
-	augroup END
-
-- Switch on syntax highlighting by adding "syntax enable" to your vimrc file.
-
-For debugging, running tmux with -v or -vv will generate server and client log
-files in the current directory.

SYNCING

@@ -0,0 +1,174 @@
+Preamble
+========
+
+Tmux on SourceForge has two git repositories [1] "tmux-code" and "tmux-openbsd".
+Here's a description of them:
+
+* "tmux-code" is the portable version, the one which contains code for other
+  operating systems, and autotools, etc., which isn't found or needed in the
+  OpenBSD base system.
+
+* "tmux-openbsd" is the version of tmux in OpenBSD base system which provides
+  the basis of the portable tmux version.
+
+Note:  The "tmux-openbsd" repository is actually handled by "git cvsimport"
+running at 15 minute intervals, so a commit made to OpenBSD's tmux CVS
+repository will take at least that long to appear in this git repository.
+(It might take longer, depending on the CVS mirror used to import the
+OpenBSD code).
+
+It is assumed that the person doing the sync has read/write access to the
+tmux-code repository on SourceForge already.
+
+If you've never used git before, git tracks meta-data about the committer
+and the author, as part of a commit, hence:
+
+% git config [--global] user.name "Your name"
+% git config [--global] user.email "you@yourdomain.com"
+
+Note that, if you already have this in the global ~/.gitconfig option, then
+this will be used.  Setting this per-repository would involve not using the
+"--global" flag above.   If you wish to use the same credentials always,
+pass the "--global" option, as shown.
+
+This is a one-off operation once the repository has been cloned, assuming
+this information has ever been set before.
+
+Cloning repositories
+====================
+
+This involves having both tmux-code and tmux-openbsd cloned, as in:
+
+% cd /some/where/useful
+% git clone ssh://${USER}@git.code.sf.net/p/tmux/tmux
+% git clone ssh://${USER}@git.code.sf.net/p/tmux/tmux-openbsd
+
+Note that you do not need additional checkouts to manage the sync -- an
+existing clone of either repositories will suffice.  So if you already have
+these checkouts existing, skip that.
+
+Adding in git-remotes
+=====================
+
+Because the portable "tmux-code" git repository and the "tmux-openbsd"
+repository do not inherently share any history between each other, the
+history has been faked between them.  This "faking of history" is something
+which has to be told to git for the purposes of comparing the "tmux" and
+"tmux-openbsd" repositories for syncing.  To do this, we must reference the
+clone of the "tmux-openbsd" repository from the "tmux-code" repository, as
+shown by the following command:
+
+% cd /path/to/tmux-code
+% git remote add obsd-tmux file:///path/to/tmux-openbsd
+
+So that now, the remote "obsd-tmux" can be used to reference branches and
+commits from the "tmux-openbsd" repository, but from the context of the
+portable "tmux-code" repository, which makes sense because it's the "tmux"
+repository which will have the updates applied to them.
+
+Fetching updates
+================
+
+To ensure the latest commits from "tmux-openbsd" can be found from within
+"tmux-code", we have to ensure the "master" branch from "tmux-openbsd" is
+up-to-date first, and then reference that update in "tmux-code", as in:
+
+% cd /path/to/tmux-openbsd
+% git checkout master
+% git pull
+
+Then back in "tmux-code":
+
+% cd /path/to/tmux-code
+% git fetch obsd-tmux-code
+
+Creating the necessary branches
+===============================
+
+Now that "tmux-code" can see commits and branches from "tmux-openbsd" by way
+of the remote name "obsd-tmux", we can now create the master branch from
+"tmux-openbsd" in the "tmux-code" repository:
+
+% git checkout -b obsd-master obsd-tmux/master
+
+Adding in the fake history points
+================================= 
+
+To tie both the "master" branch from "tmux-code" and the "obsd-master"
+branch from "tmux-openbsd" together, the fake history points added to the
+"tmux-code" repository need to be added.  To do this, we must add an
+additional refspec line, as in:
+
+% cd /path/to/tmux-code
+% git config --add remote.origin.fetch '+refs/replace/*:refs/replace/*'
+% git fetch origin
+
+Performing the Sync
+===================
+
+Make sure the "master" branch is checked out:
+
+% git checkout master
+
+The following will show commits on OpenBSD not yet synched with "tmux-code":
+
+% git log master..obsd-master
+
+From there, merge the result in, fixing up any conflicts which might arise.
+
+% git merge obsd-master
+
+Then ensure things look correct by BULDING the result of that sync:
+
+% make clean && ./autogen.sh && ./configure && make
+
+Compare the git merge result with what's on origin/master -- that is, check
+which commits you're about to push:
+
+% git log origin/master..master
+
+And if happy:
+
+% git push origin master
+
+Release tmux for next version
+=============================
+
+1. Comment the "found_debug=yes" line in configure.ac, since releases
+   don't have debugging enabled, otherwise make(1) aborts when
+   preparing the distribution.
+
+2. Update and commit README and CHANGES.  The former should be checked for
+   anything outdated and updated with a list of things that might break
+   upgrades and the latter should mention all the major changes since
+   the last version.
+
+3. Tag with:
+
+   % git tag -a 1.X
+
+   Where "1.X" is the next version.
+
+   Push the tag out with:
+
+   % git push 1.X
+
+4. Build the tarball with make dist.  Now that it's using autoconf there
+   shouldn't be any weird files (such as the original and rejection files
+   from patch(1)) but it doesn't hurt taking a quick look at it.
+
+5. Split the release changes into a new file.  This should be named
+   tmux-$VERSION-readme to make sourceforge show it automagically in specific
+   parts of the project page.
+
+6. Upload the tarball and the above file. Make the tarball the default
+   download by selecting all operating systems under the file details.
+
+7. Run make update-index.html upload-index.html to replace %%VERSION%%.
+
+8. Bump version in configure.ac and uncomment "found_debug=yes" to create
+   a debug build by default.
+
+9. Update freshmeat.

-- window creation/idle time
+NOTES
-- better errors when creating new windows/sessions (how?)
+=====
+
+This file describes rough notes regarding ideas for potential future tmux
+development.  It's not necessarily guaranteed that items in this TODO file
+will ever get implemented.
+
+It is asked therefore, that anyone thinking of undertaking a task in this
+TODO file, email tmux-users@lists.sf.net to discuss the feature.
+
+Thie file is split up between tmux user interface (UI) issues, and terminal
+compatibility issues.
+
+TMUX UI ISSUES
+==============
+
 - implicitly add exec to the commands for new windows (switch to disable it)?
-- it would be nice to have multichar commands eg C-b K K
+- bring back detach-session to detach all clients on a session?
-- commands:
- 	extend list-clients to list clients attached to a session (-a for all?)
-	bring back detach-session to detach all clients on a session?
 - allow fnmatch for -c, so that you can, eg, detach all clients
 - garbage collect window history (100 lines at a time?) if it hasn't been used
-  in $x time (need window creation/use times)
+  in $x time
-- lift SHRT_MAX limits for history?
 - flags to centre screen in window
-- better terminal emulation
 - activity/bell should be per-window not per-link? what if it is cur win in
   session not being watched?
-- next prev word etc in command prompt
-- many more info() displays for various things
-- input.c is too complicated. simplify?
-- use a better termcap internally instead of screen, perhaps xterm
-- fix rxvt cursor fg issue (text under cursor can have non-white fg)
 - should be able to move to a hidden pane and it would be moved into view. pane
   number in status line/top-right would be cool for this
 - support other mouse modes (highlight etc) and use it in copy mode
 - set-remain-on-exit is a bit of a hack, some way to do it generically?
-- set-option should be set-session-option and should be overall global options
-      also quiet, utf8 and maybe other flags?
-  -g is a bit unexpected in conf file
-- clear window title on exit
-- the output code (tty.c) could do with optimisation depending on term
-  capabilities
 - would be nice to be able to use "--" to mark start of command w/ neww etc
   to avoid quoting
 - make command sequences more usable: don't require space after ;, handle
   errors better
-- attach should have a flag to create session if it doesn't exist
 - choice and more mode would be better per client than per window?
 - hooks to which commands may be attached, for example: tmux add-hook
   "new-session" if-shell "[ -e $HOME/.tmux-session.conf ]" source-file
   $HOME/.tmux-session.conf
-- get it passing all the vttest tests that don't require resizing the terminal
-- esc seq to set window name and title should be documented, and name variant
-  should clear automatic-rename
 - way to set socket path from config file
-- XXX once env stuff is in, default-path and VISUAL/EDITOR should be picked up
-  when session is started
-- what about utmp etc? can tmux update it like screen? setgid?
 - warts on current naming:
   	- display-time but message-fg/bg/attr
 	- list-* vs show-*
 	- server-info
 	- up-pane/down-pane/swap-pane -U/swap-pane -D vs next-*/previous-*
 	- split-window -> split-pane??
-- tidy up and prioritise todo list ;-)
-- neww and attach can create a session if none exists?
-       would work fine with config file since
-- a way for force-width/height to apply to only one pane (how?)
-- command to list what is actually running in each window with command line,
-  pid (need some adaption of the osdep code)
-- support for bce
-- it would be nice if the start/end line keys in copy mode were aware of
-  wrapped lines
 - some way to force a screen to use the entire terminal even if it is forced
   to be smaller by other clients. pan smaller terminal? (like screen F)
-		-- idea of a "view" onto a window, need base x/y offsets
+	-- idea of a "view" onto a window, need base x/y offsets for redraw
-		   for redraw
-- handle resize better in copy mode
-- way to copy stuff that is off screen due to resize
 - commands should be able to succeed or fail and have || or && for command
   lists
-- support the mouse wheel to scroll through history
+- some way to keep a command running continually and just use its last line of
-- some way to KEEP a command running continually and just use its LAST line of
   output
-- bind commands to mouse buttons
 - UTF-8 to a non-UTF-8 terminal should not be able to balls up
   the terminal - www/ruby-addressable; make regress
-- copy mode needs a tidy/cleanup
-- ability to save history (to buffer?)
-- multiple keys could be done with tables, ie have prefixes go and instead
-	bind -n ^A prefix-table "default"
-  where prefix-table sets command lookup table and sets prefix flag, then next
-  key is looked up in that table
-- UTF-8 should be a pointer into a combined string buffer
-- check irssi (term_charset) works with UTF-8
 - support esc-esc to quit in modes
 - fix ctrl+F1-F4 output. to what?
-- look into xterm clearing its selection when scrolling etc
+- better utf8 support: window names, prompt input, message display
-- better utf8 support:
-  	 window names
-	 prompt input
-	 message display
-	 copy and paste cursor and wide characters
-	 ...?
-- option so that when session is destroyed, attach client to another session
-  rather than exiting
-- session history for client and last-session command
-- option to change status line colour when current window is in a mode?
 - option to move copy mode indicator into status line
-- list-buffer/show-buffer should display UTF-8
 - selection behaviour closer to vi in vi mode
 - live update: server started with -U connects to server, requests sessions and
   windows, receives fds
-- convert status line history to be server global (anything else?)
-- something for -t "last window in session" so a session can be used as a stack
-- command to show a tree of sessions-windows-panes (active marked with *)
 - sort out inheriting config from shell on new sessions/windows:
         should pick up default-path/termios/etc from client if possible,
 	else leave empty/default
-- define custom layouts
 - link panes into multiple windows
-- -h option to capture-pane to capture the history as well
 - bells should be passed between sessions with visual-bell etc
-- use screen-256color when started on 256 colour terminal??
-- if-shell/run-shell should block further command execution in the same command
   sequence until its shell exits, to allow them to be used from the config file
 - better session sharing: create-socket command to create socket somewhere (-r
   flag for readonly)
-- allow buffer to be specified when copying in copy mode
+- multiline status line (no?)
-- multiline status line
-- flag for absolute pane size to resize-pane
-- sanity check input to socket
-- stdin fd should be passed up to parent so load-buffer and others could use it
-  for nonattaching clients
-- environment should be set up for jobs
-- select-buffer command
-- fix jobs so they block in config file rather than executing at an arbitrary
-  future point -- need state stored in client so other clients can proceed
-- rectangle copy:
-	when selecting leftward, cursor should be inside block per emacs
-	key to rotate corner at which cursor is
-- double C-a should walk back over wrapped lines like C-e
 - support title stack, both internally and externally
 	http://docs.freebsd.org/cgi/getmsg.cgi?fetch=1149299+0+archive/2010/freebsd-questions/20100207.freebsd-questions
-- copy buffers should be global, limit can be server option, nuke copy-buffer
+- some way to pad # stuff with spaces, #!2T maybe
-  command
+- a binding to "scroll down and exit at bottom" copy mode
-- command to show status line information briefly when it is off
+- some way to pass keystrokes in copy mode through to underlying window. why?
+- last window update time and # replacement for it for display-message
+- find-window across sessions - other ways to make session handling easier?
+- ' and " should be parsed the same (eg "\e" vs '\e') in config and command
+  prompt?
+- command to toggle selection not to move it in copy-mode
+- audit of escape sequence support vs xterm
+- support binding keys to mouse (mouse-select-pane -> mouse-keys or something,
+  mouse click == select-pane -t %%, mouse scroll up == copy-mode)
+- bind commands to key sequences? -- make it so ALL keys go through a table,
+  first an implicit table in which C-b is the only default binding to a
+  command that says "next key from $othertable" and so on. means -n can
+  go away as well
+- monitor, bell etc should monitor /all/ panes in the window not just one
+- a history of commands that can be reversed (reverse member of each command,
+  and a buffer)
+- info() when changing to same window
+- way to add dest for break-pane; maybe some easier way to unbreak-pane
+- case insensitive searching
+- incremental searching in copy mode.
+- configurable borders and empty space filler for when panes < window?
+- mouse-select-pane will screw up with !MODE_MOUSE_STANDARD (it sets the
+  flag on w/o checking the others before calling tty_update_mode)
+- pass shell commands as argv rather than strings, allow them to be specified
+  in commands without quotes
+- named buffers and allow gaps in the stack
+- monitor-activity is broken in several ways with multiple clients
+- monitor-activity should be more powerful (eg set a region)
+- maybe a way to put pane names instead of window names in status line
+- support for borderless panes
+- wait-for command 20130222153957.GY6782@yelena.nicm.ath.cx
+- last-pane across sessions
+- panes should have names like windows
+- command-prompt doesn't work if made read-only. why?
+- option to quote format eg #{session_name:quoted}
+- formats need conditions for >0 (for #P)
+- fetch full command line on !Linux, and add option to strip prefixes
+  such as "sh " "/bin/sh " etc etc
+- synchronize-windows option
+- append to buffer in copy mode
+- way to paste w/o trailing whitespace
+- flag to switch-client to switch all clients
+- history of layouts and undo/redo flags to selectl
+- way to tag a layout as a number/name
+- optimize pane redraws, 20120318184853.GK10965@yelena.nicm.ath.cx
+- support multibyte key strings
+- allow commands to be executed when certain patterns in a screen
+  are clicked on with the mouse
+- flag to make next/previous commands skip a window
+- way to do tmux command/run-shell from mode keys
+- send command to all windows
+- choose-pane command (augment choose-tree to do this?)
+- choose-mode and copy-mode are very similar. Perhaps make choose-mode a subset
+  of copy-mode in that it inherits key-bindings and other traits but not all
+- add -c for new-session like new-window
+- flag to choose-* for sort order (eg sort windows/sessions/clients by last
+  used time) - perhaps using formats (but what about numeric sort)?
+- instead of separate window and session options, just one master options list
+  with each option having a type (window or session), then options on window,
+  on session, and global. for window options we look window->session->global,
+  and for session we look session->global
+- maybe keep last layout + size around and if size reverts just put it back
+- way to set hints/limits about pane size for resizing
+- revamp layouts: they are too complicated, should be more closely integrated,
+  should support hints, layout sets should just be a special case of custom
+  layouts, and we should support panes that are not attached to a cell at
+  all. this could be the time to introduce panelink to replace layout_cell
+- run-shell/if-shell should support formats
+- attach should take a pane and select it as well as attaching
+- attach should have a flag to create session if it doesn't exist. or better
+  new a flag to attach it
+
+TERMINAL ISSUES
+================
+
+- use a better termcap internally instead of screen, perhaps xterm
+- clear window title on exit (see using xterm title stack)
+- get it passing all the vttest tests that don't require resizing the terminal
+- support for bce
+- use screen-256color when started on 256 colour terminal?
+* We need a tmux terminfo entry to document the extensions we are using in
+  upstream terminfo. Must NOT change (only add or remove) anything from
+  TERM=screen so we can fallback!
