On 12 July 2026, three years after the initial release, the regular
support for Debian 12, alias "bookworm", has come to an end. The Debian
Long Term Support (LTS)=C2=A0[1] Team is taking over security support from
the Security and Release Teams.

Information for users
---------------------

Bookworm LTS will be supported until 30 June 2028.

Where possible, users are encouraged to upgrade their machines to Debian
13, alias "trixie", the current Debian stable release. The life cycle of
Debian releases encompasses three years of regular support plus two
years of Long Term Support. Debian 12 will thus receive Long Term
Support until 30 June 2028, five years after the initial release.

Users that need to stick with Debian 12 can find relevant information
about Debian Long Term Support at LTS/Using=C2=A0[2]. Important information
and updates regarding Bookworm LTS specifically can be found at LTS/
Bookworm=C2=A0[3].

    3: https://wiki.debian.org/LTS/Bookworm

Debian 12 LTS users are invited to subscribe to the announcement mailing
list=C2=A0[4] to receive notifications about security updates, or to follow
the latest advisories through the LTS Security Information=C2=A0[5] webpage=
.

A few packages are not covered by the Bookworm LTS support. Non-
supported packages installed in users' machines can be identified by
installing the debian-security-support=C2=A0[6] package. If debian-security=
-
support detects an unsupported package which is critical to you, please
get in touch with <[email protected]>.

ppc64el supported as a Bookworm LTS architecture.
-------------------------------------------------

One of the differences between regular support and long term support is
the set of supported architectures. The Debian LTS team is pleased to
announce that 64-bit Little Endian PowerPC (ppc64el) will be supported,
for the first time, as an LTS architecture. The supported architectures
in Debian 12 LTS are thus amd64, i386, arm64, armhf and ppc64el.


Bullseye LTS reaching end of support.
-------------------------------------

Debian 11, alias "bullseye", was initially released on 14 August 2021,
and its two years of Long Term Support will end on 31 August 2026. Users
of Debian 11 LTS are strongly encouraged to upgrade to Debian 12, and
then to Debian 13.

Debian and its LTS Team would like to thank all contributing users,
developers, sponsors and other Debian teams who are making it possible
to extend the life of previous stable releases.

If you rely on Debian LTS, please consider joining the team=C2=A0[7],
providing patches, testing or funding the efforts=C2=A0[8].
