The Debian Long Term Support (LTS) Team hereby announces that Debian 11
"bullseye" support has reached its end-of-life today, 31 August 2026,
five years after its initial release on 14 August 2021.
Starting in September, Debian will not provide further security updates
for Debian 11. A subset of "bullseye" packages will be supported by
external parties. Detailed information can be found at Extended LTS [1].

The Debian LTS Team is currently providing security support for Debian
12 "bookworm", the current oldstable release. Thanks to the combined
efforts of different teams including the Security Team, the Release
Team, and the LTS Team, the Debian 12 life cycle encompasses five years.
Debian 12 will receive Long Term Support until 30 June 2028. The
supported architectures in Debian 12 LTS are amd64, i386, arm64, armhf
and ppc64el.

"bullseye" LTS, please refer to LTS/Using [2].

developers, sponsors and other Debian teams who are making it possible
to extend the life of previous stable releases, and who have made
Bullseye LTS a success.
