CHANGES FROM 2.0 to 2.1 18 October 2015<p>Incompatible Changes
====================<p>* Mouse-mode has been rewritten. There's now no longer options for:
- mouse-resize-pane
- mouse-select-pane
- mouse-select-window
- mode-mouse<p><pre><code> Instead there is just one option: 'mouse' which turns on mouse support
entirely.</code></pre>
* 'default-terminal' is now a session option. Furthermore, if this is set
to 'screen-<i>' then emulate what screen does. If italics are wanted, this
can be set to 'tmux' but this is still new and not necessarily supported
on all platforms with older ncurses installs.
</i> The c0-* options for rate-limiting have been removed. Instead, a backoff
approach is used.
