At any given time, there is one stable release of Debian, which has the support of the Debian security team. When a new stable version is released, the security team will usually cover the previous version for a year or so, while they also cover the new/current version. Only stable is recommended for production use.

Debian Long Term Support (LTS) is a project to extend the lifetime of all Debian stable releases to (at least) 5 years on a limited set of architectures. Debian LTS will not be handled by the Debian security team, but by a separate group of volunteers and companies. Not all packages of the Debian archive are supported by LTS, the debian-security-support package can check for unsupported packages.

A commercial offering for Extended Long Term Support (ELTS) is also available to further extend the lifetime of Debian releases to 10 years (5 supplementary years after the 5 years offered by the LTS project). It is not an official Debian project.

More information is available on the Debian website.
