Show rpcap interface names in a tooltip when hovering an entry in the interface menu (Windows only).
Qemuwrapper support for the new Qemu networking syntax.
Option to send Qemu and Qemu-img paths to an external Qemuwrapper.
Possibility to use stylesheets from the view menu, for now only the ‘Energy saving’ theme is available.
Tooltip for clouds.
User guidance: status bar messages.
Splash screen at startup.
Small improvements and bug fixes all over the place.

Known issues:

Mac OS X: VirtualBox VMs cannot communicate with IOS VMs.
Win XP 64-bit: one Dynamips process stays alive after closing GNS3.
When using Qemu Manager on Linux: VM is stuck on “Booting from Hard Disk” message.

Notes for Mac OS X:

OSX 10.7 Lion: to use GNS3 with VirtualBox, you must copy a library included in our GNS3 Application to VirtualBox Application. (i.e. /Applications/GNS3.app/Contents/Resources/VBoxPython2.7.so to /Applications/VirtualBox.app/Contents/MacOS/VBoxPython2.7.so)
Qemu is not included in our DMG. You will have to patch and compile it yourself (sorry!).
