Debian always has at least
three releases in active maintenance:
stabledistribution contains the latest officially released distribution of Debian.
This is the production release of Debian, the one which we primarily recommend using.
stabledistribution of Debian is version 9, codenamed stretch. It was initially released as version 9 on June 17th, 2017 and its latest update, version 9.8, was released on February 16th, 2019.
testingdistribution contains packages that haven't been accepted into a
stablerelease yet, but they are in the queue for that. The main advantage of using this distribution is that it has more recent versions of software.
testingdistribution is buster.
unstabledistribution is where active development of Debian occurs. Generally, this distribution is run by developers and those who like to live on the edge. It is recommended that users running unstable should subscribe to the debian-devel-announce mailing list to receive notifications of major changes, for example upgrades that may break.
unstabledistribution is always called sid.
Release life cycle
Debian announces its new stable release on a regular basis. Users can expect 3 years of full support for each release and 2 years of extra LTS support.
