-* Option to request multiple responses when using command-prompt.
-* Improved environment handling.
-* Combine wrapped lines when pasting.
-* Option to override terminal settings (terminal-overrides).
-* Use the full range of ACS characters for drawing pane separator lines.
-* Customisable mode keys.
-* Status line colour options, with embedded colours in status-left/right, and
-  an option to centre the window list.
-* Much improved layouts, including both horizontal and vertical splitting.
-* Optional visual bell, activity and content indications.
-* Set the utf8 and status-utf8 options when the server is started with -u.
-* display-message command to show a message in the status line, by default some
-  information about the current window.
-* Improved current process detection on NetBSD.
-* unlink-window -k is now the same as kill-window.
-* attach-session now works from inside tmux.
-* A system-wide configuration file, /etc/tmux.conf.
-* A number of new commands in copy mode, including searching.
-* Panes are now specified using the target (-t) notation.
-* -t now accepts fnmatch(3) patterns and looks for prefixes.
-* Translate \r into \n when pasting.
-* Support for binding commands to keys without the prefix key
-* Support for alternate screen (terminfo smcup/rmcup).
-* Maintain data that goes off screen after reducing the window size, so it can
-  be restored when the size is increased again.
-* New if-shell command to test a shell command before running a tmux command.
-* tmux now works as the shell.
-* Man page reorganisation.
-* Many minor additions, much code tidying and several bug fixes.
