Includes a new status icon (the icon in the menu bar) more in keeping with recent OS X aesthetics and which includes Retina images. (The old icon may be selected as the 'Tunnelblick 3.3 icon' on the Appearance panel of the 'VPN Details…' window.)
Changes to Tunnelblick's handling of computer sleep:
Adds a 'Disconnect when computer goes to sleep' checkbox on the 'Advanced' settings window; it is checked by default.
Before reconnecting any configurations after the computer wakes up from sleep, Tunnelblick waits for an Internet connection if checking that the IP address changed is allowed; or waits for a timeout period (the default is five seconds) if it is not.
Allows selection of the display on which notification windows will be shown if multiple displays are available.
Includes several other enhancements and fixes a problem converting some OpenVPN configurations to Tunnelblick VPN Configurations.
