Debian version history

Releases of Debian GNU/Linux, a computer operating system From Wikipedia, the free encyclopedia

Debian version history

Debian releases do not follow a fixed schedule. Recent releases have been made around every two years by the Debian Project. The most recent version of Debian is Debian version 12, codename "Bookworm".[1] The next up and coming release of Debian is Debian 13, codename "Trixie".[2]

Debian always has at least three active branches at any time: "stable", "testing" and "unstable".[3] 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.[4]

Naming convention

Debian distribution codenames are based on the names of characters from the Toy Story films. Debian's unstable trunk is named after Sid, a character who regularly destroyed his toys.[5]

Release cycle

Debian Unstable, known as "Sid", contains all the latest packages as soon as they are available, and follows a rolling-release model.[6]

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".[7]

On average about every two years, Debian Testing enters a "freeze" cycle, where new packages are held back unless they fix critical bugs.[8][9] This frozen state lasts on average 7 months (but can be as short as one month).[8] Once Debian Testing doesn't contain any more release critical bugs, it is declared "stable" and released with a version number.[9]

Future version
  1. The number of hardware architectures supported
  2. Extended long-term support (ELTS) provided by Freexian[10] but made available to all Debian users, as noted on official Debian pages. There is no kernel support, and only sponsored packages are supported.[11]
  3. Only 9 are candidates for stable releases.
  4. As of 07/05/2022
  5. As of 28/09/2024
  6. As of 28/09/2024

When a release transitions to long-term support phase (LTS-phase), security is no longer handled by the main Debian security team.[92] Only a subset of Debian architectures are eligible for Long Term Support, and there is no support for packages in backports.[93]

Release history

Summarize
Perspective

Debian 1.0 was never released, as a vendor accidentally shipped a development release with that version number.[94] The package management system dpkg and its front-end dselect were developed and implemented on Debian in a previous release. A transition from the a.out binary format to the ELF binary format had already begun before the planned 1.0 release. The only supported architecture was Intel 80386 (i386).[12]

Debian 1.1 (Buzz)

Debian 1.1 (Buzz), released 17 June 1996, contained 474 packages. Debian had fully transitioned to the ELF binary format and used Linux kernel 2.0.[95]

Debian 1.2 (Rex)

Debian 1.2 (Rex), released 12 December 1996, contained 848 packages maintained by 120 developers.[96]

Debian 1.3 (Bo)

Debian 11 (Bullseye) with GNOME

Debian 11 (Bullseye) was released on 14 August 2021.[1] It is based on the Linux 5.10 LTS kernel and will be supported for five years.[260]

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.[261]

Bullseye dropped the remaining Qt4/KDE 4 libraries and Python 2,[262][263] and shipped with Qt 5.15 KDE Plasma 5.20.[264] Available desktops include Gnome 3.38, KDE Plasma 5.20, LXDE 11, LXQt 0.16, MATE 1.24, and Xfce 4.16.[265][266][267]

Bullseye does not support the older big-endian 32-bit MIPS architectures.[268] This is not to be confused with the more common i386 32-bit architecture which is still supported.

The first of the code freezes, readying Debian 11 for release, began on 12 January 2021.[269]
