We are proud to announce the version 0.3 of GNS3, this version is considered as a beta.
A lot of new features and bug-fixes are available, the most important are:
– Support of Ethernet, ATM and Frame-Relay switches 
– Included hub (Bridge of Dynamips) and cloud (external connections) devices 
– Added the Dynagen console (nearly all commands supported) 
– New GUI settings 
– Improved node configurator 
– Load and save in Dynagen INI-like configuration files 
– Multi-language support (howto for translators soon) 
A documentation has been written and is available in the documentation section on the website
Note: the official name of the project is now GNS3 (not gns-3 nor GNS-3)
Thank you for reporting bugs with details
