Debian is a free and open-source operating system developed based on Linux. It is one of the oldest and most imporant Linux distributions and serves as the base for many other distributions. With one of the largest and most active communities in FOSS software, Debian is constantly being updated and improved by its developers. Major releases are made around every two years by the Debian Project although Debian releases do not follow a fixed schedule. The most recent version of Debian is Debian version 13, codename "Trixie". The next up and coming release of Debian is Debian 14, codename "Forky".

Debian always has at least three active branches at any time: "stable", "testing" and "unstable". The stable branch is considered the primary release and what most people refer to when talking about Debian. The testing branch contains packages that have been imported from unstable. Testing has significantly more up-to-date packages than stable and is frozen some time before a release to become the next version of Debian. The unstable release (also known as Sid) is the branch where active development takes place. It is the most volatile version of Debian.

When the Debian stable branch is replaced with a newer release, the current stable becomes an "oldstable" release. When the Debian stable branch is replaced again, the oldstable release becomes the "oldoldstable" release. Oldoldstable is eventually moved to the archived releases repository.

01Naming convention

Debian distribution codenames are based on the names of characters from the Toy Story films. Debian's unstable branch is named after Sid, a character who regularly destroyed his toys.

02Release cycle

Debian Unstable, known as "Sid", contains all the latest packages as soon as they are available, and follows a rolling-release model.

Once a package has been in Debian Unstable for 2-10 days (depending on the urgency of the upload), doesn't introduce critical bugs and doesn't break other packages (among other conditions), it is included in Debian Testing, also known as "next-stable".

On average about every two years, Debian Testing enters a "freeze" cycle, where new packages are held back unless they fix critical bugs. This frozen state lasts on average 7 months (but can be as short as one month). Once Debian Testing doesn't contain any more release critical bugs, it is declared "stable" and released with a version number.

When a release transitions to long-term support phase (LTS-phase), security is no longer handled by the main Debian security team. Only a subset of Debian architectures are eligible for Long Term Support, and there is no support for packages in backports.

04Release history

Debian 1.0 was never released, as a vendor accidentally shipped a development release with that version number. The package management system dpkg and its front-end dselect were developed and implemented on Debian in a previous release.

Debian 11 (Bullseye)

Debian 11 (Bullseye) was released on 14 August 2021. It is based on the Linux 5.10 LTS kernel and will be supported for five years.

On 12 November 2020, it was announced that "Homeworld", by Juliette Taka, will be the default theme for Debian 11, after winning a public poll held with eighteen choices.

Bullseye dropped the remaining Qt4/KDE 4 libraries and Python 2, and shipped with Qt 5.15 KDE Plasma 5.20. Available desktops include Gnome 3.38, KDE Plasma 5.20, LXDE 11, LXQt 0.16, MATE 1.24, and Xfce 4.16.

Bullseye does not support the older big-endian 32-bit MIPS architectures.

The first of the code freezes, readying Debian 11 for release, began on 12 January 2021.

Development freeze timetable:

  • 12 January 2021: transition freeze

Debian 12 (Bookworm)

Debian 12 (Bookworm) was released on 10 June 2023. It is based on Linux kernel v6.1 LTS, and uses GNOME 43 as its default desktop environment, but as usual many other desktops are available, such as KDE Plasma 5.27, LXDE 11, LXQt 1.2.0, MATE 1.26, and Xfce 4.18.

Bookworm raised the compatibility level of its 32 bit x86 PC port from i586 to i686 compatibility.

Debian 12 (Bookworm) is the last version of Debian with KDE Plasma 5.

Starting with Debian 12, non-free firmware packages from the "non-free-firmware" section of the Debian archive was enabled by default in the official installer and live images if and when the system determines that these packages are required, such as with modern Wi-Fi cards and modern graphics cards. A change was also made to the Debian Social Contract to allow for this change to be made.

On 13 October 2022, the Release Team announced the freeze development milestone timeline for this release:

  • 12 January 2023: transition and toolchain
  • 12 February 2023: soft freeze
  • 12 March 2023: hard freeze

Debian 13 (Trixie)

Debian 13, codenamed Trixie, was released 9 August 2025. It uses the v6.12 LTS kernel.

Debian 13 adds support for 64 bit RISC-V.

Debian 13 drops support for the mipsel architecture, and drops the installers for the i386 (all 32-bit x86 CPUs) and armel architectures.

Debian directs users to keep i386 systems on Debian 12 or retiring the system in question, as the remaining packages are intended for running 32-bit x86 software on 64-bit systems and require the SSE2 CPU instruction set that most 32-bit x86 CPUs don't support.

Debian 13 features KDE Plasma 6.

  • [2024-12-31]: Debian Installer Trixie Alpha 1 release
  • [2025-03-15]: Transition and Toolchain Freeze
