CHANGES FROM 3.1c TO 3.2
* Add a flag to disable keys to close a message.
* Permit shortcut keys in buffer, client, tree modes to be configured with a
format (-K flag to choose-buffer, choose-client, choose-tree).
* Add a current_file format for the config file being parsed.
* When display-message used in config file, show the message after the config
file finishes.
* Add client-detached notification in control mode.
* Improve performance of format evaluation.
* Make jump command support UTF-8 in copy mode.
* Support X11 colour names and other colour formats for OSC 10 and 11.
* Add "pipe" variants of "copy-pipe" commands which do not copy.
* Include "focused" in client flags.
* Send Unicode directional isolate characters around horizontal pane borders if
the terminal supports UTF-8 and an extension terminfo(5) capability "Bidi" is
present.
* Add a -S flag to new-window to make it select the existing window if one
with the given name already exists rather than failing with an error.
* Addd a format modifier to check if a window or session name exists (N/w or
N/s).
* Add compat clock_gettime for older macOS.
* Add a no-detached choice to detach-on-destroy which detaches only if there
are no other detached sessions to switch to.
* Add rectangle-on and rectangle-off copy mode commands.
* Change so that window_flags escapes # automatically. A new format
window_raw_flags contains the old unescaped version.
* Add -N flag to never start server even if command would normally do so.
* With incremental search, start empty and only repeat the previous search if
the user tries to search again with an empty prompt.
* Add a value for remain-on-exit that only keeps the pane if the program
failed.
* Add a -C flag to run-shell to use a tmux command rather than a shell command.
* Do not list user options with show-hooks.
* Remove current match indicator in copy mode which can't work anymore since we
only search the visible region.
* Make synchronize-panes a pane option and add -U flag to set-option to unset
an option on all panes.
* Make replacement of ##s consistent when drawing formats, whether followed by
[ or not. Add a flag (e) to the q: format modifier to double up #s
* Add -N flag to display-panes to ignore keys.
* Change how escaping is processed for formats so that ## and # can be used in
styles.
* Add a 'w' format modifier for string width.
* Add support for Haiku.
* Expand menu and popup -x and -y as formats.
* Add numeric comparisons for formats.
* Fire focus events even when the pane is in a mode.
* Add -O flag to display-menu to not automatically close when all mouse buttons
are released.
* Allow fnmatch(3) wildcards in update-environment.
* Disable nested job expansion so that the result of #() is not expanded again.
* Use the setal capability as well as (tmux's) Setulc.
* Add -q flag to unbind-key to hide errors.
* Allow -N without a command to change or add a note to an existing key.
* Add a -w flag to set- and load-buffer to send to clipboard using OSC 52.
* Add -F to set-environment and source-file.
* Allow colour to be spelt as color in various places.
* Add n: modifier to get length of a format.
* Respond to OSC colour requests if a colour is available.
* Add a -d option to display-message to set delay.
* Add a way for control mode clients to subscribe to a format and be notified
of changes rather than having to poll.
* Add some formats for search in copy mode (search_present, search_match).
* Do not wait on shutdown for commands started with run -b.
* Add -b flags to insert a window before (like the existing -a for after) to
break-pane, move-window, new-window.
* Make paste -p the default for ].
* Add support for pausing a pane when the output buffered for a control mode
client gets too far behind. The pause-after flag with a time is set on the
pane with refresh-client -f and a paused pane may be resumed with
refresh-client -A.
* Allow strings in configuration files to span multiple lines - newlines and
any leading whitespace are removed, as well as any following comments that
couldn't be part of a format. This allows long formats or other strings to be
annotated and indented.
* Instead of using a custom parse function to process {} in configuration
files, treat as a set of statements the same as outside {} and convert back
to a string as the last step. This means the rules are consistent inside and
outside {}, %if and friends work at the right time, and the final result
isn't littered with unnecessary newlines.
* Add support for extended keys - both xterm(1)'s CSI 27 ~ sequence and the
libtickit CSI u sequence are accepted; only the latter is output. tmux will
only attempt to use these if the extended-keys option is on and it can detect
that the terminal outside supports them (or is told it does with the
"extkeys" terminal feature).
* Add an option to set the pane border lines style from a choice of single
lines (ACS or UTF-8), double or heavy (UTF-8), simple (plain ASCII) or number
(the pane numbers). Lines that won't work on a non-UTF-8 terminal are
translated back into ACS when they are output.
* Make focus events update the latest client (like a key press).
* Store UTF-8 characters differently to reduce memory use.
* Fix break-pane -n when only one pane in the window.
* Instead of sending all data to control mode clients as fast as possible, add
a limit of how much data will be sent to the client and try to use it for
panes with some degree of fairness.
* Add an active-pane client flag (set with attach-session -f, new-session -f
or refresh-client -f). This allows a client to have an independent active
pane for interactive use (the window client pane is still used for many
things however).
* Add a mark to copy mode, this is set with the set-mark command (bound to X)
and appears with the entire line shown using copy-mode-mark-style and the
marked character in reverse. The jump-to-mark command (bound to M-x) swaps
the mark and the cursor positions.
* Add a -D flag to make the tmux server run in the foreground and not as a
daemon.
* Do not loop forever in copy mode when search finds an empty match.
* Fix the next-matching-bracket logic when using vi(1) keys.
* Add a customize mode where options may be browsed and changed, includes
adding a brief description of each option. Bound to C-b C by default.
* Change message log (C-b ~) so there is one for the server rather than one per
client and it remains after detach, and make it useful by logging every
command.
* Add M-+ and M-- to tree mode to expand and collapse all.
* Change the existing client flags for control mode to apply for any client,
use the same mechanism for the read-only flag and add an ignore-size flag.
refresh-client -F has become -f (-F stays for backwards compatibility) and
attach-session and switch-client now have -f flags also. A new format
client_flags lists the flags and is shown by list-clients by default.
This separates the read-only flag from "ignore size" behaviour (new
ignore-size) flag - both behaviours are useful in different circumstances.
attach -r and switchc -r remain and set or toggle both flags together.
* Store and restore cursor position when copy mode is resized.
* Export TERM_PROGRAM and TERM_PROGRAM_VERSION like various other terminals.
* Add formats for after hook command arguments: hook_arguments with all the
arguments together; hook_argument_0, hook_argument_1 and so on with
individual arguments; hook_flag_X if flag -X is present; hook_flag_X_0,
hook_flag_X_1 and so on if -X appears multiple times.
* Try to search the entire history first for up to 200 ms so a search count can
be shown. If it takes too long, search the visible text only.
* Use VIS_CSTYLE for paste buffers also (show \012 as \n).
* Change default formats for tree mode, client mode and buffer mode to be more
compact and remove some clutter.
* Add a key (e) in buffer mode to open the buffer in an editor. The buffer
contents is updated when the editor exits.
* Add -e flag for new-session to set environment variables, like the same flag
for new-window.
* Improve search match marking in copy mode. Two new options
copy-mode-match-style and copy-mode-current-match-style to set the style for
matches and for the current match respectively. Also a change so that if a
copy key is pressed with no selection, the current match (if any) is copied.
* Sanitize session names like window names instead of forbidding invalid ones.
* Check if the clear terminfo(5) capability starts with CSI and if so then
assume the terminal is VT100-like, rather than relying on the XT capability.
* Improve command prompt tab completion and add menus both for strings and -t
and -s (when used without a trailing space). command-prompt has additional
flags for only completing a window (-W) and a target (-T), allowing C-b ' to
only show windows and C-b . only targets.
* Change all the style options to string options so they can support formats.
Change pane-border-active-style to use this to change the border colour when
in a mode or with synchronize-panes on. This also implies a few minor changes
to existing behaviour:
- set-option -a with a style option automatically inserts a comma between the
old value and appended text.
- OSC 10 and 11 no longer set the window-style option, instead they store the
colour internally in the pane data and it is used as the default when the
option is evaluated.
- status-fg and -bg now override status-style instead of the option values
being changed.
* Add extension terminfo(5) capabilities for margins and focus reporting.
* Try $XDG_CONFIG_HOME/tmux/tmux.conf as well as ~/.config/tmux/tmux.conf for
configuration file (the search paths are in TMUX_CONF in Makefile.am).
* Remove the DSR 1337 iTerm2 extension and replace by the extended device
attributes sequence (CSI > q) supported by more terminals.
* Add a -s flag to copy-mode to specify a different pane for the source
content. This means it is possible to view two places in a pane's history at
the same time in different panes, or view the history while still using the
pane. Pressing r refreshes the content from the source pane.
* Add an argument to list-commands to show only a single command.
* Change copy mode to make copy of the pane history so it does not need to
freeze the pane.
* Restore pane_current_path format from portable tmux on OpenBSD.
* Wait until the initial command sequence is done before sending a device
attributes request and other bits that prompt a reply from the terminal. This
means that stray relies are not left on the terminal if the command has
attached and then immediately detached and tmux will not be around to receive
them.
* Add a -f filter argument to the list commands like choose-tree.
* Move specific hooks for panes to pane options and windows for window options
rather than all hooks being session options. These hooks are now window
options:
window-layout-changed
window-linked
window-pane-changed
window-renamed
window-unlinked
And these now pane options:
pane-died
pane-exited
pane-focus-in
pane-focus-out
pane-mode-changed
pane-set-clipboard
Any existing configurations using these hooks on a session rather than
globally (that is, set-hook or set-option without -g) may need to be changed.
* Show signal names when a process exits with remain-on-exit on platforms which
have a way to get them.
* Start menu with top item selected if no mouse and use mode-style for the
selected item.
* Add a copy-command option and change copy-pipe and friends to pipe to it if
used without arguments, allows all the default copy key bindings to be
changed to pipe with one option rather than needing to change each key
binding individually.
* Tidy up the terminal detection and feature code and add named sets of
terminal features, each of which are defined in one place and map to a
builtin set of terminfo(5) capabilities. Features can be specified based on
TERM with a new terminal-features option or with the -T flag when running
tmux. tmux will also detect a few common terminals from the DA and DSR
responses.
This is intended to make it easier to configure tmux's use of terminfo(5)
even in the presence of outdated ncurses(3) or terminfo(5) databases or for
features which do not yet have a terminfo(5) entry. Instead of having to grok
terminfo(5) capability names and what they should be set to in the
terminal-overrides option, the user can hopefully just give tmux a feature
name and let it do the right thing.
The terminal-overrides option remains both for backwards compatibility and to
allow tweaks of individual capabilities.
* Support mintty's application escape sequence (means tmux doesn't have to
delay to wait for Escape, so no need to reduce escape-time when using
mintty).
* Change so main-pane-width and height can be given as a percentage.
* Support for the iTerm2 synchronized updates feature (allows the terminal to
avoid unnecessary drawing while output is still in progress).
* Make the mouse_word and mouse_line formats work in copy mode and enable the
default pane menu in copy mode.
* Add a -T flag to resize-pane to trim lines below the cursor, moving lines out
of the history.
* Add a way to mark environment variables as "hidden" so they can be used by
tmux (for example in formats) but are not set in the environment for new
panes. set-environment and show-environment have a new -h flag and there is a
new %hidden statement for the configuration file.
* Change default position for display-menu -x and -y to centre rather than top
left.
* Add support for per-client transient popups, similar to menus but which are
connected to an external command (like a pane). These are created with new
command display-popup.
* Change double and triple click bindings so that only one is fired (previously
double click was fired on the way to triple click). Also add default double
and triple click bindings to copy the word or line under the cursor and
change the existing bindings in copy mode to do the same.
* Add a default binding for button 2 to paste.
* Add -d flag to run-shell to delay before running the command and allow it to
run without a command so it just delays.
* Add C-g to cancel command prompt with vi keys as well as emacs, and q in
command mode.
* When the server socket is given with -S, create it with umask 177 instead of
117 (because it may not be in a safe directory like the default directory in
/tmp).
* Add a copy-mode -H flag to hide the position marker in the top right.
* Add number operators for formats (+, -, *, / and m),
CHANGES FROM 2.1 to 2.2 10 April 2016
Incompatible Changes
====================
* The format strings which referenced time have been removed. Instead:
#{t:window_activity}
can be used.
* Support for TMPDIR has been removed. Use TMUX_TMPDIR instead.
* UTF8 detection how happens automatically if the client supports it, hence
the:
mouse-utf8
utf8
options has been removed.
* The:
mouse_utf8_flag
format string has been removed.
* The -I option to show-messages has been removed. See:
#{t:start_time}
format option instead.
Normal Changes
==============
* Panes are unzoomed with selectp -LRUD
* New formats added:
#{scroll_position}
#{socket_path}
#{=10:...} -- limit to N characters (from the start)
#{=-10:...} -- limit to N characters (from the end)
#{t:...} -- used to format time-based formats
#{b:...} -- used to ascertain basename from string
#{d:...} -- used to ascertain dirname from string
#{s:...} -- used to perform substitutions on a string
* Job output is run via the format system, so formats work again
* If display-time is set to 0, then the indicators wait for a key to be
pressed.
* list-keys and list-commands can be run without starting the tmux server.
* kill-session learns -C to clear all alerts in all windows of the session.
* Support for hooks (internal for now), but hooks for the following have been
implemented:
alert-bell
alert-silence
alert-activity
client-attached
client-detached
client-resized
pane-died
pane-exited
* RGB (24bit) colour support. The 'Tc' flag must be set in the external TERM
entry (using terminal-overrides or a custom terminfo entry).

CHANGES FROM 1.9 to 1.9a 22 February 2014
NOTE: This is a bug-fix release to address some important bugs which just
missed the 1.9 deadline, but were found afterwards.
Normal Changes
==============
* Fix crash due to uninitialized lastwp member of layout_cell
* Fix -fg/-bg/-style with 256 colour terminals.
CHANGES FROM 1.8 to 1.9, 20 February 2014
NOTE: This release has bumped the tmux protocol version. It is therefore
advised that the prior tmux server is restarted when this version of tmux is
installed, to avoid protocol mismatch errors for newer clients trying to
talk to an older running tmux server.
Incompatible Changes
====================
* 88 colour support has been removed.
* 'default-path' has been removed. The new-window command accepts '-c' to
cater for this. The previous value of "." can be replaced with: 'neww -c
$PWD', the previous value of '' which meant current path of the pane can
be specified as: 'neww -c "#{pane_current_path}"'
Deprecated Changes
==================
* The single format specifiers: #A -> #Z (where defined) have been
deprecated and replaced with longer-named equivalents, as listed in the
FORMATS section of the tmux manpage.
* The various foo-{fg,bg,attr} commands have been deprecated and replaced
with equivalent foo-style option instead. Currently this is still
backwards-compatible, but will be removed over time.
Normal Changes
==============
* A new environment variable TMUX_TMPDIR is now honoured, allowing the
socket directory to be set outside of TMPDIR (/tmp/ if not set).
* If -s not given to swap-pane the current pane is assumed.
* A #{pane_syncronized} format specifier has been added to be a conditional
format if a pane is in a syncronised mode (c.f. syncronize-panes)
* Tmux now runs under Cygwin natively.
* Formats can now be nested within each other and expanded accordingly.
* Added 'automatic-rename-format' option to allow the automatic rename
mechanism to use something other than the default of
#{pane_current_command}.
* new-session learnt '-c' to specify the starting directory for that session
and all subsequent windows therein.
* The session name is now shown in the message printed to the terminal when
a session is detached.
* Lots more format specifiers have been added.
* Server race conditions have been fixed; in particular commands are not run
until after the configuration file is read completely.
* Case insensitive searching in tmux's copy-mode is now possible.
* attach-session and switch-client learnt the '-t' option to accept a window
and/or a pane to use.
* Copy-mode is only exited if no selection is in progress.
* Paste key in copy-mode is now possible to enter text from the clipboard.
* status-interval set to '0' now works as intended.
* tmux now supports 256 colours running under fbterm.
* Many bug fixes!
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.
* Panes can now emit focus notifications for certain applications
which use those.
* run-shell and if-shell now accept formats.
* 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 1.7 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.

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 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.
