Changes to Terminal in El Capitan Can someone please describe the changes made to Terminal.app in El Capitan? I've just noticed that mouse events started working in Tmux, which is awesome!

I had the following set in my tmux.conf:

setw -g mode-mouse on
set -g mouse-select-pane on
set -g mouse-resize-pane on
set -g mouse-select-window on


which did not work because Terminal prior to OS X 10.11 did not pass mouse events to underlying processes. Now it wonderfully works. What other changes are included in new Terminal?
The command lines are now marked with square brackets as in the screen snippet below.
