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 2.3 to 2.4 20 April 2017

Incompatible Changes
====================

* Key tables have undergone major changes. Mode key tables are no longer
separate from the main key tables. All mode key tables have been removed,
together with the -t flag to bind-key and unbind-key.

The emacs-edit, vi-edit, emacs-choose and vi-choose tables have been replaced
by fixed key bindings in the command prompt and choose modes. The mode-keys
and status-keys options remain.

The emacs-copy and vi-copy tables have been replaced by the copy-mode and
copy-mode-vi tables. Commands are sent using the -X and -N flags to
send-keys. So the following:

bind -temacs-copy C-Up scroll-up
bind -temacs-copy -R5 WheelUpPane scroll-up

Becomes:

bind -Tcopy-mode C-Up send -X scroll-up
bind -Tcopy-mode WheelUpPane send -N5 -X scroll-up

This changes allows the full command parser (including command sequences) and
command set to be used - for example, the normal command prompt with editing
and history is now used for searching, jumping, and so on instead of a custom
one. The default C-r binding is now:

bind -Tcopy-mode C-r command-prompt -p'search up' "send -X search-backward '%%'"

There are also some new commmands available with send -X, such as
copy-pipe-and-cancel.
* set-remain-on-exit has gone -- can be achieved with hooks instead.
* Hooks: before hooks have been removed and only a selection of commands now
have after hooks (they are no longer automatic). Additional hooks have been
added.
* The xterm-keys option now defaults to on.

Normal Changes
==============

* Support for mouse double and triple clicks.
* BCE (Background Colour Erase) is now supported.
* All occurrences of a search string in copy mode are now highlighted;
additionally, the number of search results is displayed. The highlighting
updates interactively with the default emacs key bindings (incremental
search).
* source-file now understands glob patterns.
* Formats now have simple comparisons:

#{==:a,b}
#{!=:a,b}

* There are the following new formats:

- #{version} -- the tmux server version;
- #{client_termtype} -- the terminal type of the client;
- #{client_name} -- the name of a client;
- #{client_written} -- the number of bytes written to the client.

* The configuration file now accepts %if/%endif conditional blocks which are
processed when it is parsed; the argument is a format string (useful with the
new format comparison options).
* detach-client now has -E to execute a command replacing the client instead of
exiting.
* Add support for custom command aliases, this is an array option which
contains items of the form "alias=command". This is consulted when an
unknown command is parsed.
* break-pane now has -n to specify the new window name.
* OSC 52 support has been added for programs inside tmux to set a tmux buffer.
* The mouse "all event" mode (1003) is now supported.
* Palette setting is now possible (OSC 4 and 104).
* Strikethrough support (a recent terminfo is required).
* Grouped sessions can now be named (new -t).
* terminal-overrides and update-environment are now array options (the previous
set -ag syntax should work without change).
* There have been substantial performance improvements.

CHANGES FROM 2.2 to 2.3 29 September 2016

Incompatible Changes
====================

None.

Normal Changes
==============

* New option 'pane-border-status' to add text in the pane borders.
* Support for hooks on commands: 'after' and 'before' hooks.
* 'source-file' understands '-q' to suppress errors for nonexistent files.
* Lots of UTF8 improvements, especially on MacOS.
* 'window-status-separator' understands #[] expansions.
* 'split-window' understands '-f' for performing a full-width split.
* Allow report count to be specified when using 'bind-key -R'.
* 'set -a' for appending to user options (@foo) is now supported.
* 'display-panes' can now accept a command to run, rather than always
selecting the pane.
