=== What to use ===
To choose which release might suit your requirements best read http://people.debian.org/~osamu/newbie.html#best [http://lists.debian.org/debian-devel/2003/debian-devel-200301/msg01753.html addendum]
== Introduction ==
Debian is under continual development. The latest release is Debian <<DebianVersion(stable)>>. It is also (currently) known as '''[[DebianStable|stable]]''' or by its codename "[[DebianStretch|Stretch]]".
Line 13: Line 13:
=== Point releases ===
There are also point releases, which are updates to the stable releases. For the most part, these just add security updates. Debian 2.2r7 was released on July 13th 2002.
Each version also corresponds to a set of named software repositories (at least one per CPU architecture).
Line 16: Line 15:
Older releases include At any given time, there is one stable release of Debian, which has the support of the [[Teams/Security|Debian security team]]. When a new stable version is released, the security team will usually cover the previous version [[https://www.debian.org/security/faq#lifespan|for a year or so]], while they also cover the new/current version. Only stable is recommended for production use.

   * DebianSlink - v2.1 - March 1999
There are also two main development repositories '''[[DebianUnstable|unstable]]''' and '''[[DebianTesting|testing]]''' which are continually updated during the development of the next stable release. The latest packages arrive in unstable (which always has the codename "Sid"). Packages are automatically copied from unstable to testing when they meet criteria such as lack of [[https://www.debian.org/Bugs/Developer#severities|release-critical bugs]], and dependencies being satisfied by other packages in testing.
Line 27: Line 19:
(Did I forgot a version - add it. If you know some highlights of the versions please add.) == Choosing ==

End users should generally choose to run either stable or testing. Stable is recommended for applications requiring production-level stability and security (servers, firewalls etc) and is also recommended for those who are new to Linux. Testing is recommended for slightly more advanced users who want newer software on their desktops and who are capable of [[reportbug|reporting]] and fixing bugs to help Debian.

[[https://www.debian.org/doc/manuals/debian-faq/ch-choosing|Choosing a debian distribution]] discusses the pros and cons of choosing one Debian distribution over another. And the [[DebianSoftware|overview of software for Debian Stable]] describes common ways Debian stable is enhanced with newer software or otherwise given extended capabilities.

[[https://www.debian.org/doc/manuals/debian-faq/ch-ftparchives|The Debian FTP archives]] chapter of the [[https://www.debian.org/doc/manuals/debian-faq/|Debian FAQ]] has even more information .

== Current Releases/Repositories ==
 * [[DebianOldStable|oldstable]] - The previous stable release ([[DebianJessie|Jessie]]).
 * [[DebianStable|stable]] - The current stable release ([[DebianStretch|Stretch]]).
 * [[DebianTesting|testing]] - The next generation release ([[DebianBuster|Buster]]).
 * [[DebianUnstable|unstable]] - The unstable development release ([[DebianSid|Sid]]), where new or updated packages are introduced.

Also:

 * [[DebianExperimental|experimental]] - Not really a release ([[#Codenames|RC-Buggy]]), but a repository where packages are tested (experimented) if they are not suited for unstable.
 * [[Backports|backport]] - Not a release, but a repository for updated packages for {{{stable}}}.

Introduction

Debian is under continual development. The latest release is Debian 11.2. It is also (currently) known as stable or by its codename "Stretch".

Each version also corresponds to a set of named software repositories (at least one per CPU architecture).

At any given time, there is one stable release of Debian, which has the support of the Debian security team. When a new stable version is released, the security team will usually cover the previous version for a year or so, while they also cover the new/current version. Only stable is recommended for production use.

There are also two main development repositories unstable and testing which are continually updated during the development of the next stable release. The latest packages arrive in unstable (which always has the codename "Sid"). Packages are automatically copied from unstable to testing when they meet criteria such as lack of release-critical bugs, and dependencies being satisfied by other packages in testing.

Choosing

End users should generally choose to run either stable or testing. Stable is recommended for applications requiring production-level stability and security (servers, firewalls etc) and is also recommended for those who are new to Linux. Testing is recommended for slightly more advanced users who want newer software on their desktops and who are capable of reporting and fixing bugs to help Debian.

Choosing a debian distribution discusses the pros and cons of choosing one Debian distribution over another. And the overview of software for Debian Stable describes common ways Debian stable is enhanced with newer software or otherwise given extended capabilities.

The Debian FTP archives chapter of the Debian FAQ has even more information .

Current Releases/Repositories

Also:

  • experimental - Not really a release (RC-Buggy), but a repository where packages are tested (experimented) if they are not suited for unstable.

  • backport - Not a release, but a repository for updated packages for stable.
