iTerm2 2.0 (Intel)

What's new in this version:

Major New Features:
- Deep tmux integration:Have you ever had an ssh session lost because you had to reboot, had a network failure, or the power went out? Are you tired of giving up a keystroke to tmux or screen? Suffer no longer! iTerm2 and tmux are now deeply integrated. By installing a special version of tmux, it gains the ability to speak directly to iTerm2. When you run tmux with -CC, iTerm2 will open real, native windows or tabs for each tmux window. The whole state of your tmux session is reflected in native iTerm2 windows. As you interact with a window, your typing is sent back to tmux. Any time you resize a window, add a split pane, close a split pane, close a window, or open a window (with Shell->tmux->new window), that action happens in tmux as well as in iTerm2.
- A "Toolbelt" has been added. It's a drawer that opens to the right of a window and shows running jobs, paste history, a field for taking notes, and lets you open new windows/tabs/splits. Look for the Toolbelt menu.
- Add "triggers." A trigger is an action that is performed when text matching some regular expression is received in a terminal session.
- Add "coprocesses." A coprocess is a process, such as a script, that receives input from a terminal and whose output is fed into the terminal session as though the user were typing it. You can use them to automate interaction with scripts, download files with ZModem, and more.
- You can now edit the smart selection regexes in Prefs>Profiles>Advanced. You can also assign actions that are added to the context menu when you right click on text that matches a smart selection rule.
- Support for OS 10.7 features including fullscreen, retina graphics, and window restoration.

New Preferences:
- Add support for tiled background images (Foy Savas)

- Add next/previous pane action.

- Add hidden preference PinchToChangeFontSizeDisabled to turn off pinch to change font size
- Ask for confirmation before deleting a profile.
