Debian Long Term Support
Debian Long Term Support (LTS) is a project to extend the lifetime of all Debian stable releases to (at least) 5 years. Debian LTS is handled by a group of volunteers and companies interested in making it a success.
Debian LTS is not handled by the Debian Security and Release teams. Thus the Debian LTS team takes over security maintenance of the various releases once the Debian Security team stops its work.
