GNS3 version 2.0 beta 4 has been released. This should be the last BETA version before moving to release candidates, please note it is not fully stable yet and some bugs are still expected. A final version of GNS3 2.0 will be released early this year.
Major new features of 2.0 include “save as you go” (thanks to a new architecture), smart packet capture, VPCS/clouds/switches templates, cloud node refactoring, a new NAT node and much more. Please see What’s new in GNS3 version 2.0 for a detailed overview.
IMPORTANT: No rollback is possible once you open a project in version 2.0. Backup all your projects, settings and snapshot the GNS3 VM. Version 2.0 is in beta stage which means many things could be broken or not work as expected. Please do not upgrade if you are working on something important like a certification etc.
Files for Windows and Mac OS X can be downloaded from here
For an installation from our PPA (Ubuntu based Linux):
sudo add-apt-repository -r ppa:gns3/ppa
sudo add-apt-repository ppa:gns3/unstable
sudo apt-get update
sudo apt-get install gns3-gui
For other Linux users we recommend an installation via Pypi.
pip3 install gns3-gui==2.0.0b4
pip3 install gns3-server==2.0.0b4
Linux users may have to log out and log back in to refresh groups, otherwise they may no longer have access to uBridge (required to run GNS3).
Snapshot the VM!! If you want to be able to rollback to a previous version of GNS3. In the VM, you must select "version" in the menu and change it to 2.0dev
