Dear ftp-masters,
The package gns3 is unmaintained by upstream, package version is 0.8.7, our last released version is 1.4.5. All recent versions of GNS3 are distributed from our official PPA.
This creates confusion among user who install the package thinking it is the last version.
Official Debian maintainer is unreachable.
Please remove from Debian.
Thank you,
Jeremy
GNS3 development team
