tmux is a "terminal multiplexer". It allows a
number of terminals (or windows) to be accessed
and controlled from a single terminal. It is
intended to be a simple, modern, BSD-licensed
alternative to programs such as GNU screen.

The code has been switched to libevent. New commands/options were added. The commands set-window-option, and show-window-options have been changed to be aliases to set -w, and show -w respectively. Panes can now be referred to as top, bottom, top-left, etc. Server-wide options have been added which can be set with set-option -s, and shown with show-options -s. Permit S- prefix on keys for shift when the terminal/terminfo supports them. Window targets (-t flag) can now refer to the last window (!), next (+), and previous (-) window by number. Lots of mode keys added in copy mode. There are additional code reductions, bug fixes, and manpage enhancements.
