GNS3 version 2.0 beta 1 has been released. While this version is more stable than our previous alphas, please note it is not fully stable and some bugs are still expected. A final version of GNS3 2.0 will be released early next 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.
