Support status guide

End of life (EOL) is the end of a product’s useful life. When a product reaches the end of its life cycle, the manufacturer no longer supports it. The following table explains the different phases of a product’s lifecycle. Testing status is when the product is initially released and EOL is when product support is no longer offered. The time between these two points is the support timeframe.


The software is not yet publicly available. It is in testing phase i.e., alpha, beta, release preview etc.


The software is actively supported by the vendor.

Phasing Out

The software will soon reach its end of life. You need to look for upgrade or migration options. The software will automatically go into phasing out status 2 months before end of life.

End Of Life

The software is no longer supported by the vendor. You need to make sure your system and environment are safe.

A newer version of Debian is released every 2 years and is then supported by a security team for 3 years. This means that users still have one whole year to upgrade to the latest version of Debian while the older version is still fully supported.

An LTS version of Debian releases is also offered which is supported for a total of 5 years, instead of the traditional 3. However, it is not maintained by the same security team. Instead, the LTS version is handled by a group of volunteers and companies.

Another version offered of the Debian operating system is the Extended LTS version. It is not an official project of the Debian community but offers support for a total of 10 years, which has been labeled as “Extended Support” in the table above.
