Debian 0.01 through 0.90 (August-December 1993)
Debian 0.91 (January 1994): This release had a simple package system which could install and uninstall packages. The project had grown to several dozen people at this point.
Debian 0.93R5 (March 1995): Responsibility for each package was clearly
assigned to a developer by this point, and the package manager
dpkg) was used to install packages after the installation of a
Debian 0.93R6 (November 1995):
dselect appears. This was the last
Debian release using the a.out binary format; there were about 60 developers.
The first master.debian.org server was built by Bdale Garbee and hosted by HP
in parallel with the 0.93R6 release. The deployment of an explicit master
server on which Debian developers would construct each release led directly to
the formation of the Debian mirror network, and indirectly to the development
of many of the policies and procedures used to manage the project today.
Debian 1.0 was never released: InfoMagic, a CD vendor, accidentally shipped a development release of Debian and entitled it 1.0. On December 11th 1995, Debian and InfoMagic jointly announced that this release was screwed. Bruce Perens explains that the data placed on the "InfoMagic Linux Developer's Resource 5-CD Set November 1995" as "Debian 1.0" is not the Debian 1.0 release, but an early development version which is only partially in the ELF format, will probably not boot or run correctly, and does not represent the quality of a released Debian system. To prevent confusion between the premature CD version and the actual Debian release, the Debian Project has renamed its next release to "Debian 1.1". The premature Debian 1.0 on CD is deprecated and should not be used.
The hosting of master.debian.org moved from HP to i-Connect.Net around the end of 1995. Michael Neuffer and Shimon Shapiro, founders of i-Connect.Net, hosted master on their own hardware for a little more than a year. During this time, they provided many services to Debian, including running what was essentially the New Maintainer process of the day, and significantly aiding the growth of the early Debian mirror network.
Debian 1.1 Buzz (June 17th, 1996): This was the first Debian release with a code name. It was taken, like all others so far, from a character in one of the Toy Story movies... in this case, Buzz Lightyear. By this time, Bruce Perens had taken over leadership of the Project from Ian Murdock, and Bruce was working at Pixar, the company that produced the movies. This release was fully ELF, used Linux kernel 2.0, and contained 474 packages.
Debian 1.2 Rex (December 12th, 1996): Named for the plastic dinosaur in the Toy Story movies. This release consisted of 848 packages maintained by 120 developers
Debian 1.3 Bo (June 5th, 1997): Named for Bo Peep, the shepherdess. This release consisted of 974 packages maintained by 200 developers.
Debian 2.0 Hamm (July 24th, 1998): Named for the piggy-bank in the Toy Story movies. This was the first multi-architecture release of Debian, adding support for the Motorola 68000 series architectures. With Ian Jackson as Project Leader, this release made the transition to libc6, and consisted of over 1500 packages maintained by over 400 developers.
Debian 2.1 Slink (March 9th, 1999): Named for the slinky-dog in the
movie. Two more architectures were added,
SPARC. With Wichert
Akkerman as Project Leader, this release consisted of about 2250 packages and
required 2 CDs in the official set. The key technical innovation was the
introduction of apt, a new package management interface. Widely emulated, apt
addressed issues resulting from Debian's continuing growth, and established a
new paradigm for package acquisition and installation on Open Source operating
Debian 2.2 Potato (15 August 2000): Named for "Mr Potato
Head" in the Toy Story movies. This release added support for
With Wichert still serving as Project Leader, this release consisted of more
than 3900 binary packages derived from over 2600 source packages maintained by
more than 450 Debian developers.
Debian 3.0 Woody (19 July 2002): Named for the main character the
Toy Story movies: "Woody" the cowboy. Even more
architectures were added in this release:
MIPS (big endian),
MIPS (little endian) and
S/390. This is
also the first release to include cryptographic software due to the
restrictions for exportation being lightened in the US, and also the
first one to include KDE, now that the license issues with QT were resolved.
With Bdale Garbee recently appointed Project Leader, and more than 900 Debian
developers, this release contained around 8,500 binary packages and 7 binary
CDs in the official set.
Debian 3.1 Sarge (6 June 2005): named for the sergeant of the Green
Plastic Army Men. No new architectures were added to the release, although an
unofficial AMD64 port was published at the same time and distributed through
Alioth project hosting
site. This release features a new installer:
debian-installer, a modular piece of software that feature automatic
hardware detection, unattended installation features and was released fully
translated to over thirty languages. It was also the first release to include
a full office suite: OpenOffice.org. Branden Robinson had just been appointed
as Project Leader. This release was made by more than nine hundred Debian
developers, and contained around 15,400 binary packages and 14 binary CDs in
the official set.
Debian 4.0 Etch (8 April 2007): named for the sketch toy in the movie.
One architecture was added in this release:
AMD64, and official
was dropped. This release continued using the debian-installer, but
featuring in this release a graphical installer, cryptographic verification of
downloaded packages, more flexible partitioning (with support for encrypted
partitions), simplified mail configuration, a more flexible desktop selection,
simplified but improved localization and new modes, including a rescue
mode. New installations would not need to reboot through the installation
process as the previous two phases of installation were now integrated. This
new installer provided support for scripts using composed characters and
complex languages in its graphical version, increasing the number of available
translations to over fifty. Sam Hocevar was appointed Project Leader the very
same day, and the project included more than one thousand and thirty Debian
developers. The release contained around 18,000 binary packages over 20 binary
CDs (3 DVDs) in the official set. There were also two binary CDs available to
install the system with alternate desktop environments different to the default
Debian 5.0 Lenny (February 2009): named for the wind up binoculars in
the Toy Story movies. One architecture was added in this release:
ARM EABI (or
armel), providing support for newer ARM processors and deprecating the
old ARM port (arm). The
m68k port was not included in
this release, although it was still provided in the unstable
distribution. This release did not feature the
although much work on the port had been done to make it qualify it did not meet
requirements for this release.
Support of small factor devices in this release was increased by the added support for Marvell's Orion platform which was used in many storage devices and also provided supported several Netbooks. Some new build tools were added which allowed Debian packages to be cross-built and shrunk for embedded ARM systems. Also, netbooks of varied vendors were now supported and the distribution provided software more suitable for computers with relatively low performance.
It was also the first release to provide free versions of Sun's Java technology, making it possible to provide Java applications in the main section.
Debian 6.0 Squeeze (February 2011): named for the green three-eyed aliens.
The release was frozen on August 6, 2010, with many of the Debian developers gathered at the 10th DebConf at New York City.
While two architectures (alpha and hppa) were dropped, two architectures of the
port (kfreebsd-i386 and kfreebsd-amd64) were made available as
technology preview, including the kernel and userland tools as well as
common server software (though not advanced desktop features yet). This was
the first time a Linux distribution has been extended to also allow use of a
The new release introduced a dependency based boot sequence, which allowed for parallel init script processing, speeding system startup.
Debian 7.0 Wheezy (May 2013): named for the rubber toy penguin with a red bow tie.
The release was frozen on June 30, 2012, very close to the Debian developers gathering in the 12th DebConf at Managua, Nicaragua.
One architecture was included in this release (armhf) and this release introduced multi-arch support, which allowed users to install packages from multiple architectures on the same machine. Improvements in the installation process allowed visually impaired people to install the system using software speech for the first time.
This was also the first release that supported the installation and booting in devices using UEFI firmware.
Debian 8 Jessie (April 2015): named for the cow girl doll who first appeared in Toy Story 2.
This release introduced for the first time the systemd init system as default. Two new architectures were introduced: arm64 and ppc64el and three architectures were dropped: s390 (replaced by s390x), ia64 and sparc. The Sparc architecture had been present in Debian for 16 years, but lacked developer support to make it maintenable in the distribution.
The release included many security improvements such as a new kernel that nullified a whole set of security vulnerabilities (symlink attacks), a new way to detect packages which were under security support, more packages built with hardened compiler flags and a new mecahnism (needrestart) to detect sub-systems which had to be restarted in order to propagate security updates after an upgrade.
Debian 9 Stretch (June 2017): named for the toy rubber octopus with suckers on her eight long arms that appeared in Toy Story 3.
The release was frozen on February 7th, 2017.
Support for the powerpc architecture was dropped in this release, whileas the mips64el architecture was introduced. This release introduced debug packages with a new repository in the archive, packages from this repository provided debug symbols automatically for packages.
Debian 10 Buster (no release date yet): named for Andy's pet dog, received as Christmas present in the end of Toy Story.
Debian 11 Bullseye (no release date yet): named for Woody's wooden toyhorse that appeared in Toy Story 2.
