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 12, codenamed bookworm. It was initially released as version 12.0 on June 10th, 2023 and its latest update, version 12.1, was released on July 22nd, 2023.
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 trixie.
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.
