The Facsimile project has adopted the newly released GNU General Public License (GPL) version 3 for all future releases.
Facsimile was previously distributed under version 2 of the GPL.
Update: Sources from the Subversion repository on SourceForge with revision numbers of 19 and higher are licensed under the GPLv3; those with revision numbers of 18 and lower are licensed under the GPLv2.
If you are using the Bazaar repository on Launchpad (which is mirrored from the SourceForge system), then be aware that the version numbers in this system differ from the Subversion system. View the COPYING file in order to accurately determine the license.
