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). From Anindya Mukherjee. + +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. + + Additions to the #[] syntax are: "align" to specify alignment (left, centre, + right), "list" for the window list and "range" to configure ranges of text + for the mouse bindings. + + The "align" keyword can also be used to specify alignment of entries in tree + mode and the pane status lines. + +* Add E: and T: format modifiers to expand a format twice (useful to expand the + value of an option). + +* The individual -fg, -bg and -attr options have been removed; they + were superseded by -style options in tmux 1.9. + +* Allow more than one mode to be opened in a pane. Modes are kept on a stack + and retrieved if the same mode is entered again. Exiting the active mode goes + back to the previous one. + +* When showing command output in copy mode, call it view mode instead (affects + pane_mode format). + +* Add -b to display-panes like run-shell. + +* Handle UTF-8 in word-separators option. + +* New "terminal" colour allowing options to use the terminal default colour + rather than inheriting the default from a parent option. + +* Do not move the cursor in copy mode when the mouse wheel is used. + +* Use the same working directory rules for jobs as new windows rather than + always starting in the user's home. + +* Allow panes to be one line or column in size. + +* Go to last line when goto-line number is out of range in copy mode. + +* Yank previously cut text if any with C-y in the command prompt, only use the + buffer if no text has been cut. + +* Add q: format modifier to quote shell special characters. + +* Add StatusLeft and StatusRight mouse locations (keys such as + MouseDown1StatusLeft) for the status-left and status-right areas of the + status line. + +* Add -Z to find-window. + +* Support for windows larger than the client. This adds two new options, + window-size and default-size, and a new command, resize-window. The + force-width and force-height options and the session_width and session_height + formats have been removed. + + The new window-size option tells tmux how to work out the size of windows: + largest means it picks the size of the largest session, smallest the smallest + session (similar to the old behaviour) and manual means that it does not + automatically resize windows. aggressive-resize modifies the choice of + session for largest and smallest as it did before. + + If a window is in a session attached to a client that is too small, only part + of the window is shown. tmux attempts to keep the cursor visible, so the part + of the window displayed is changed as the cursor moves (with a small delay, + to try and avoid excess redrawing when applications redraw status lines or + similar that are not currently visible). + + Drawing windows which are larger than the client is not as efficient as those + which fit, particularly when the cursor moves, so it is recommended to avoid + using this on slow machines or networks (set window-size to smallest or + manual). + + The resize-window command can be used to resize a window manually. If it is + used, the window-size option is automatically set to manual for the window + (undo this with "setw -u window-size"). resize-window works in a similar way + to resize-pane (-U -D -L -R -x -y flags) but also has -a and -A flags. -a + sets the window to the size of the smallest client (what it would be if + window-size was smallest) and -A the largest. + + For the same behaviour as force-width or force-height, use resize-window -x + or -y. + + If the global window-size option is set to manual, the default-size option is + used for new windows. If -x or -y is used with new-session, that sets the + default-size option for the new session. + + The maximum size of a window is 10000x10000. But expect applications to + complain and higher memory use if making a window that big. The minimum size + is the size required for the current layout including borders. + + The refresh-client command can be used to pan around a window, -U -D -L -R + moves up, down, left or right and -c returns to automatic cursor + tracking. The position is reset when the current window is changed. + +CHANGES FROM 2.7 TO 2.8 + +* Make display-panes block the client until a pane is chosen or it + times out. + +* Clear history on RIS like most other terminals do. + +* Add an "Any" key to run a command if a key is pressed that is not + bound in the current key table. + +* Expand formats in load-buffer and save-buffer. + +* Add a rectangle_toggle format. + +* Add set-hook -R to run a hook immediately. + +* Add README.ja. + +* Add pane focus hooks. + +* Allow any punctuation as separator for s/x/y not only /. + +* Improve resizing with the mouse (fix resizing the wrong pane in some + layouts, and allow resizing multiple panes at the same time). + +* Allow , and } to be escaped in formats as #, and #}. + +* Add KRB5CCNAME to update-environment. + +* Change meaning of -c to display-message so the client is used if it + matches the session given to -t. + +* Fixes to : form of SGR. + +* Add x and X to choose-tree to kill sessions, windows or panes. + +CHANGES FROM 2.6 TO 2.7 + +* Remove EVENT_* variables from environment on platforms where tmux uses them + so they do not pass on to panes. + +* Fixes for hooks at server exit. + +* Remove SGR 10 (was equivalent to SGR 0 but no other terminal seems to do + this). + +* Expand formats in window and session names. + +* Add -Z flag to choose-tree, choose-client, choose-buffer to automatically + zoom the pane when the mode is entered and unzoom when it exits, assuming the + pane is not already zoomed. This is now part of the default key bindings. + +* Add C-g to exit modes with emacs keys. + +* Add exit-empty option to exit server if no sessions (defaults to on). + +* Show if a filter is present in choose modes. + +* Add pipe-pane -I to to connect stdin of the child process. + +* Performance improvements for reflow. + +* Use RGB terminfo(5) capability to detect RGB colour terminals (the existing + Tc extension remains unchanged). + +* Support for ISO colon-separated SGR sequences. + +* Add select-layout -E to spread panes out evenly (bound to E key). + +* Support wide characters properly when reflowing. + +* Pass PWD to new panes as a hint to shells, as well as calling chdir(). + +* Performance improvements for the various choose modes. + +* Only show first member of session groups in tree mode (-G flag to choose-tree + to show all). + +* Support %else in config files to match %if; from Brad Town in GitHub issue + 1071. + +* Fix "kind" terminfo(5) capability to be S-Down not S-Up. + +* Add a box around the preview label in tree mode. + +* Show exit status and time in the remain-on-exit pane text; from Timo + Boettcher in GitHub issue 1103. + +* Correctly use pane-base-index in tree mode. + +* Change the allow-rename option default to off. + +* Support for xterm(1) title stack escape sequences (GitHub issue 1075 from + Brad Town). + +* Correctly remove padding cells to fix a UTF-8 display problem (GitHub issue + 1090). + +CHANGES FROM 2.5 TO 2.6, 05 October 2017 + +* Add select-pane -T to set pane title. + +* Fix memory leak when lines with BCE are removed from history. + +* Fix (again) the "prefer unattached" behaviour of attach-session. + +* Reorder how keys are checked to allow keys to be specified that have a + leading escape. GitHub issue 1048. + +* Support REP escape sequence (\033[b). + +* Run alert hooks based on options rather than always, and allow further bells + even if there is an existing bell. + +* Add -d flag to display-panes to override display-panes-time. + +* Add selection_present format when in copy mode (allows key bindings that do + something different if there is a selection). + +* Add pane_at_left, pane_at_right, pane_at_top and pane_at_bottom formats. + +* Make bell, activity and silence alerting more consistent by: removing the + bell-on-alert option; adding activity-action and silence-action options with + the same possible values as the existing bell-action; adding a "both" value + for the visual-bell, visual-activity and visual-silence options to trigger + both a bell and a message. + +* Add a pane_pipe format to show if pipe-pane is active. + +* Block signals between forking and resetting signal handlers so that the + libevent signal handler doesn't get called in the child and incorrectly write + into the signal pipe that it still shares with the parent. GitHub issue 1001. + +* Allow punctuation in pane_current_command. + +* Add -c for respawn-pane and respawn-window. + +* Wait for any remaining data to flush when a pane is closed while pipe-pane is + in use. + +* Fix working out current client with no target. GitHub issue 995. + +* Try to fallback to C.UTF-8 as well as en_US.UTF-8 when looking for a UTF-8 + locale. + +* Add user-keys option for user-defined key escape sequences (mapped to User0 + to User999 keys). + +* Add pane-set-clipboard hook. + +* FAQ file has moved out of repository to online. + +* Fix problem with high CPU usage when a client dies unexpectedly.
