CHANGES FROM 3.3a to 3.4
* Add options keep-last and keep-group to destroy-unattached to keep the last
session whether in a group.
* Don't allow paste-buffer into dead panes.
* Add -t to source-file.
* Rewrite combined character handling to be more consistent and to support
newer Unicode combined characters.
* Add basic support for SIXEL if built with --enable-sixel.
* Add a session, pane and user mouse range types for the status line and add
format variables for mouse_status_line and mouse_status_range so they can be
associated with different commands in the key bindings.
* Add flag (-o) to next-prompt/previous-prompt to go to OSC 133 command output.
* Add options and flags for menu styles (menu-style, menu-border-style) similar
to those existing for popups.
* Add support for marking lines with a shell prompt based on the OSC 133 extension.
* Check for libterminfo for NetBSD.
* Add "us" to styles for underscore colour.
* Add flags (-c and -y) to change the confirm key and default behaviour of
confirm-before.
* Use ncurses' new tparm_s function (added in 6.4-20230424) instead of tparm so
it does not object to string arguments in c apabilities it doesn't already
know. Also ignore errors from tparm if using previous ncurses versions.
* Set default lock command to vlock on Linux if present at build time.
* Discard mouse sequences that have the right form but actually are invalid.
* Add support for spawning panes in separate cgroups with systemd and a
configure flag (--disable-cgroups) to turn off.
* Add a format (pane_unseen_changes) to show if there are unseen changes while
in a mode.
* Remove old buffer when renaming rather than complaining.
* Add an L modifier like P, W, S to loop over clients.
* Add -f to list-clients like the other list commands.
* Extend display-message to work for control clients.
* Add a flag to display-menu to select the manu item selected when the menu is
open.
* Have tmux recognise pasted text wrapped in bracket paste sequences, rather
than only forwarding them to the program inside.
* Have client return 1 if process is interrupted to an input pane.
* Query the client terminal for foreground and background colours and if OSC 10
or 11 is received but no colour has been set inside tmux, return the colour
from the first attached client.
* Add send-keys -K to handle keys directly as if typed (so look up in key
table).
* Process escape sequences in show-buffer.
* Add a -l flag to display-message to disable format expansion.
* Add paste-buffer-deleted notification and fix name of paste-buffer-changed.
* Do not attempt to connect to the socket as a client if systemd is active.
* Add scroll-top and scroll-bottom commands to scroll so cursor is at top or
bottom.
* Add a -T flag to capture-pane to stop at the last used cell instead of the
full width. Restore the previous behaviour by making it default to off unless
-J is used.
* Add message-line option to control where message and prompt go.
* Notification when a paste buffer is deleted.
* Add a Nobr terminfo(5) capability to tell tmux the terminal does not use bright
colours for bold.
* Change g and G to go to top and bottom in menus.
* Add a third state "all" to allow-passthrough to work even in invisible panes.
* Add support for OSC 8 hyperlinks.
* Store the time lines are scrolled into history and display in copy mode.
* Add a %config-error reply to control mode for configuration file errors since
reporting them in view mode is useless.
* A new feature flag (ignorefkeys) to ignore terminfo(5) function key
definitions for rxvt.
* Pass through first argument to OSC 52 (which clipboards to set) if the
application provides it.
* Expand arguments to send-keys, capture-pane, split-window, join-pane where it
makes sense to do so.
* Ignore named buffers when choosing a buffer if one is not specified by the user.
CHANGES FROM 3.3 TO 3.3a
* Do not crash when run-shell produces output from a config file.
* Do not unintentionally turn off all mouse mode when button mode is also
present.
CHANGES FROM 3.2a TO 3.3
* Add an ACL list for users connecting to the tmux socket. Users may be
forbidden from attaching, forced to attach read-only, or allowed to attach
read-write. A new command, server-access, configures the list. File system
permissions must still be configured manually.
* Emit window-layout-changed on swap-pane.
* Better error reporting when applying custom layouts.
* Handle ANSI escape sequences in run-shell output.
* Add pane_start_path to match start_command.
* Set PWD so shells have a hint about the real path.
* Do not allow pipe-pane on dead panes.
* Do not report mouse positions (incorrectly) above the maximum of 223 in
normal mouse mode.
* Add an option (default off) to control the passthrough escape sequence.
* Support more mouse buttons when the terminal sends them.
* Add a window-resized hook which is fired when the window is actually resized
which may be later than the client resize.
* Add next_session_id format with the next session ID.
* Add formats for client and server UID and user.
* Add argument to refresh-client -l to forward clipboard to a pane.
* Add remain-on-exit-format to set text shown when pane is dead.
* With split-window -f use percentages of window size not pane size.
* Add an option (fill-character) to set the character used for unused areas of
a client.
* Add an option (scroll-on-clear) to control if tmux scrolls into history on
clear.
* Add a capability for OSC 7 and use it similarly to how the title is set (and
controlled by the same set-titles option).
* Add support for systemd socket activation (where systemd creates the Unix
domain socket for tmux rather than tmux creating it). Build with
--enable-systemd.
* Add an option (pane-border-indicators) to select how the active pane is shown
on the pane border (colour, arrows or both).
* Support underscore styles with capture-pane -e.
* Make pane-border-format a pane option rather than window.
* Respond to OSC 4 queries
* Fix g/G keys in modes to do the same thing as copy mode (and vi).
* Bump the time terminals have to respond to device attributes queries to three
seconds.
* If automatic-rename is off, allow the rename escape sequence to set an empty
name.
* Trim menu item text more intelligently.
* Add cursor-style and cursor-colour options to set the default cursor style
and colour.
* Accept some useful and non-conflicting emacs keys in vi normal mode at the
command prompt.
* Add a format modifier (c) to force a colour to RGB.
* Add -s and -S to display-popup to set styles, -b to set lines and -T to set
popup title. New popup-border-lines, popup-border-style and popup-style
options set the defaults.
* Add -e flag to set an environment variable for a popup.
* Make send-keys without arguments send the key it is bound to (if bound to a
key).
* Try to leave terminal cursor at the right position even when tmux is drawing
its own cursor or selection (such as at the command prompt and in choose
mode) for people using screen readers and similar which can make use of it.
* Change so that {} is converted to tmux commands immediately when parsed. This
means it must contain valid tmux commands. For commands which expand %% and
%%%, this now only happens within string arguments. Use of nested aliases
inside {} is now forbidden. Processing of commands given in quotes remains
the same.
* Disable evports on SunOS since they are broken.
* Do not expand the file given with tmux -f so it can contain :s.
* Bump FORMAT_LOOP_LIMIT and add a log message when hit.
* Add a terminal feature for the mouse (since FreeBSD termcap does not have kmous).
* Forbid empty session names.
* Improve error reporting when the tmux /tmp directory cannot be created or
used.
* Give #() commands a one second grace period where the output is empty before
telling the user they aren't doing anything ("not ready").
* When building, pick default-terminal from the first of tmux-256color, tmux,
screen-256color, screen that is available on the build system (--with-TERM
can override).
* Do not close popups on resize, instead adjust them to fit.
* Add a client-active hook.
* Make window-linked and window-unlinked window options.
* Do not configure on macOS without the user making a choice about utf8proc
(either --enable-utf8proc or --disable-utf8proc).
* Do not freeze output in panes when a popup is open, let them continue to
redraw.
* Add pipe variants of the line copy commands.
* Change copy-line and copy-end-of-line not to cancel and add -and-cancel
variants, like the other copy commands.
* Support the OSC palette-setting sequences in popups.
* Add a pane-colours array option to specify the defaults palette.
* Add support for Unicode zero-width joiner.
* Make newline a style delimiter as well so they can cross multiple lines for
readability in configuration files.
* Change focus to be driven by events rather than scanning panes so the
ordering of in and out is consistent.
* Add display-popup -B to open a popup without a border.
* Add a menu for popups that can be opened with button three outside the popup
or on the left or top border. Resizing now only works on the right and bottom
borders or when using Meta. The menu allows a popup to be closed, expanded to
the full size of the client, centered in the client or changed into a pane.
* Make command-prompt and confirm-before block by default (like run-shell). A
new -b flags runs them in the background as before. Also set return code for
confirm-before.
* Change cursor style handling so tmux understands which sequences contain
blinking and sets the flag appropriately, means that it works whether cnorm
disables blinking or not. This now matches xterm's behaviour.
* More accurate vi(1) word navigation in copy mode and on the status line. This
changes the meaning of the word-separators option: setting it to the empty
string is equivalent to the previous behavior.
* Add -F for command-prompt and use it to fix "Rename" on the window menu.
* Add different command histories for different types of prompts ("command",
"search" etc).
CHANGES FROM 3.2 TO 3.2a
* Add an "always" value for the "extended-keys" option; if set then tmux will
forward extended keys to applications even if they do not request them.
* Add a "mouse" terminal feature so tmux can enable the mouse on terminals
where it is known to be supported even if terminfo(5) says otherwise.
* Do not expand the filename given to -f so it can contain colons.
* Fixes for problems with extended keys and modifiers, scroll region,
source-file, crosscompiling, format modifiers and other minor issues.
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.
* Add 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-active-border-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 replies 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 are 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
be used 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),
CHANGED FROM 3.1b TO 3.1c
* Do not write after the end of the array and overwrite the stack when
colon-separated SGR sequences contain empty arguments.
CHANGES FROM 3.1a TO 3.1b
* Fix build on systems without sys/queue.h.
* Fix crash when allow-rename is on and an empty name is set.
CHANGES FROM 3.1 TO 3.1a
* Do not close stdout prematurely in control mode since it is needed to print
exit messages. Prevents hanging when detaching with iTerm2.
CHANGES FROM 3.0a TO 3.1
* Only search the visible part of the history when marking (highlighting)
search terms. This is much faster than searching the whole history and solves
problems with large histories. The count of matches shown is now the visible
matches rather than all matches.
* Search using regular expressions in copy mode. search-forward and
search-backward use regular expressions by default; the incremental versions
do not.
* Turn off mouse mode 1003 as well as the rest when exiting.
* Add selection_active format for when the selection is present but not moving
with the cursor.
* Fix dragging with modifier keys, so binding keys such as C-MouseDrag1Pane and
C-MouseDragEnd1Pane now work.
* Add -a to list-keys to also list keys without notes with -N.
* Do not jump to next word end if already on a word end when selecting a word;
fixes select-word with single character words and vi(1) keys.
* Fix top and bottom pane calculation with pane border status enabled.
* Add support for adding a note to a key binding (with bind-key -N) and use
this to add descriptions to the default key bindings. A new -N flag to
list-keys shows key bindings with notes. Change the default ? binding to use
this to show a readable summary of keys. Also extend command-prompt to return
the name of the key pressed and add a default binding (/) to show the note
for the next key pressed.
* Add support for the iTerm2 DSR 1337 sequence to get the terminal version.
* Treat plausible but invalid keys (like C-BSpace) as literal like any other
unrecognised string passed to send-keys.
* Detect iTerm2 and enable use of DECSLRM (much faster with horizontally split
windows).
* Add -Z to default switch-client command in tree mode.
* Add ~ to quoted characters for %%%.
* Document client exit messages in the manual page.
* Do not let read-only clients limit the size, unless all clients are
read-only.
* Add a number of new formats to inspect what sessions and clients a window is
present or active in.
* Change file reading and writing to go through the client if necessary. This
fixes commands like "tmux loadb /dev/fd/X". Also modify source-file to
support "-" for standard input, like load-buffer and save-buffer.
* Add ~/.config/tmux/tmux.conf to the default search path for configuration
files.
* Bump the escape sequence timeout to five seconds to allow for longer
legitimate sequences.
* Make a best effort to set xpixel and ypixel for each pane and add formats for
them.
* Add push-default to status-left and status-right in status-format[0].
* Do not clear search marks on cursor movement with vi(1) keys.
* Add p format modifier for padding to width and allow multiple substitutions
in a single format.
* Add -f for full size to join-pane (like split-window).
* Do not use bright when emulating 256 colours on an 8 colour terminal because
it is also bold on some terminals.
* Make select-pane -P set window-active-style also to match previous behaviour.
* Do not truncate list-keys output.
* Turn automatic-rename back on if the \033k rename escape sequence is used
with an empty name.
* Add support for percentage sizes for resize-pane ("-x 10%"). Also change
split-window and join-pane -l to accept similar percentages and deprecate the
-p flag.
* Add -F flag to send-keys to expand formats in search-backward and forward
copy mode commands and copy_cursor_word and copy_cursor_line formats for word
and line at cursor in copy mode. Use for default # and * binding with vi(1)
keys.
* Add formats for word and line at cursor position in copy mode.
* Add formats for cursor and selection position in copy mode.
* Support all the forms of RGB colour strings in OSC sequences rather than
requiring two digits.
* Limit lazy resize to panes in attached sessions only.
* Add an option to set the key sent by backspace for those whose system uses ^H
rather than ^?.
* Change new-session -A without a session name (that is, no -s option also) to
attach to the best existing session like attach-session rather than a new
one.
* Add a "latest" window-size option which tries to size windows based on the
most recently used client. This is now the default.
* Add simple support for OSC 7 (result is available in the pane_path format).
* Add push-default and pop-default for styles which change the colours and
attributes used for #[default]. These are used in status-format to restore
the behaviour of window-status-style being the default for
window-status-format.
* Add window_marked_flag.
* Add cursor-down-and-cancel in copy mode.
* Default to previous search string for search-forward and search-backward.
* Add -Z flag to rotate-window, select-pane, swap-pane, switch-client to
preserve zoomed state.
* Add -N to capture-pane to preserve trailing spaces.
* Add reverse sorting in tree, client and buffer modes.
CHANGES FROM 3.0 TO 3.0a
* Do not require REG_STARTEND.
* Respawn panes or windows correctly if default-command is set.
* Add missing option for after-kill-pane hook.
* Fix for crash with a format variable that doesn't exist.
* Do not truncate list-keys output on some platforms.
* Do not crash when restoring a layout with only one pane.
CHANGES FROM 2.9 TO 3.0
* Workaround invalid layout strings generated by older tmux versions and add
some additional sanity checks
* xterm 348 now disables margins when resized, so send DECLRMM again after
resize.
* Add support for the SD (scroll down) escape sequence.
* Expand arguments to C and s format modifiers to match the m modifier.
* Add support for underscore colours (Setulc capability must be added with
terminal-overrides as described in tmux(1)).
* Add a "fill" style attribute for the fill colour of the drawing area (where
appropriate).
* New -H flag to send-keys to send literal keys.
* Format variables for pane mouse modes (mouse_utf8_flag and mouse_sgr_flag)
and for origin mode (origin_flag).
* Add -F to refresh-client for flags for control mode clients, only one flag
(no-output) supported at the moment.
* Add a few vi(1) keys for menus.
* Add pane options, set with set-option -p and displayed with show-options -p.
Pane options inherit from window options (so every pane option is also
a window option). The pane style is now configured by setting window-style
and window-active-style in the pane options; select-pane -P and -g now change
the option but are no longer documented.
* Do not document set-window-option and show-window-options. set-option -w and
show-options -w should be used instead.
* Add a -A flag to show-options to show parent options as well (they are marked
with a *).
* Resize panes lazily - do not resize unless they are in an attached, active
window.
* Add regular expression support for the format search, match and substitute
modifiers and make them able to ignore case. find-window now accepts -r to
use regular expressions.
* Do not use $TMUX to find the session because for windows in multiple sessions
it is wrong as often as it is right, and for windows in one session it is
pointless. Instead use TMUX_PANE if it is present.
* Do not always resize the window back to its original size after applying a
layout, keep it at the layout size until it must be resized (for example when
attached and window-size is not manual).
* Add new-session -X and attach-session -x to send SIGHUP to parent when
detaching (like detach-client -P).
* Support for octal escapes in strings (such as \007) and improve list-keys
output so it parses correctly if copied into a configuration file.
* INCOMPATIBLE: Add a new {} syntax to the configuration file. This is a string
similar to single quotes but also includes newlines and allows commands that
take other commands as string arguments to be expressed more clearly and
without additional escaping.
A literal { and } or a string containing { or } must now be escaped or
quoted, for example '{' and '}' instead of { or }, or 'X#{foo}' instead of
X#{foo}.
* New <, >, <= and >= comparison operators for formats.
* Improve escaping of special characters in list-keys output.
* INCOMPATIBLE: tmux's configuration parsing has changed to use yacc(1). There
is one incompatible change: a \ on its own must be escaped or quoted as
either \\ or '\' (the latter works on older tmux versions).
Entirely the same parser is now used for parsing the configuration file
and for string commands. This means that constructs previously only
available in .tmux.conf, such as %if, can now be used in string commands
(for example, those given to if-shell - not commands invoked from the
shell, they are still parsed by the shell itself).
* Add support for the overline attribute (SGR 53). The Smol capability is
needed in terminal-overrides.
* Add the ability to create simple menus. Introduces new command
display-menu. Default menus are bound to MouseDown3 on the status line;
MouseDown3 or M-MouseDown3 on panes; MouseDown3 in tree, client and
buffer modes; and C-b < and >.
* Allow panes to be empty (no command). They can be created either by piping to
split-window -I, or by passing an empty command ('') to split-window. Output
can be sent to an existing empty window with display-message -I.
* Add keys to jump between matching brackets (emacs C-M-f and C-M-b, vi %).
* Add a -e flag to new-window, split-window, respawn-window, respawn-pane to
pass environment variables into the newly created process.
* Hooks are now stored in the options tree as array options, allowing them to
have multiple separate commands. set-hook and show-hooks remain but
set-option and show-options can now also be used (show-options will only show
hooks if given the -H flag). Hooks with multiple commands are run in index
order.
* Automatically scroll if dragging to create a selection with the mouse and the
cursor reaches the top or bottom line.
* Add -no-clear variants of copy-selection and copy-pipe which do not clear the
selection after copying. Make copy-pipe clear the selection by default to be
consistent with copy-selection.
* Add an argument to copy commands to set the prefix for the buffer name, this
(for example) allows buffers for different sessions to be named separately.
* Update session activity on focus event.
* Pass target from source-file into the config file parser so formats in %if
and %endif have access to more useful variables.
* Add the ability to infer an option type (server, session, window) from its
name to show-options (it was already present in set-option).
CHANGES FROM 2.9 TO 2.9a
* Fix bugs in select-pane and the main-horizontal and main-vertical layouts.
CHANGES FROM 2.8 TO 2.9
* Attempt to preserve horizontal cursor position as well as vertical with
reflow.
* Rewrite main-vertical and horizontal and change layouts to better handle the
case where all panes won't fit into the window size, reduce problems with
pane border status lines and fix other bugs mostly found by Thomas Sattler.
* Add format variables for the default formats in the various modes
(tree_mode_format and so on) and add a -a flag to display-message to list
variables with values.
* Add a -v flag to display-message to show verbose messages as the format is
parsed, this allows formats to be debugged
* Add support for HPA (\033[`).
* Add support for origin mode (\033[?6h).
* No longer clear history on RIS.
* Extend the #[] style syntax and use that together with previous format
changes to allow the status line to be entirely configured with a single
option.
Now that it is possible to configure their content, enable the existing code
that lets the status line be multiple lines in height. The status option can
now take a value of 2, 3, 4 or 5 (as well as the previous on or off) to
configure more than one line. The new status-format array option configures
the format of each line, the default just references the existing status-*
options, although some of the more obscure status options may be eliminated
in time.
