-- The short descriptions for unstable and experimental suggest that packages go through experimental and sometimes directly to unstable. My understanding is that new (either updated or packages that don't exist in Debian) go to unstable unless the maintainer wants to receive some testing in experimental before uploading it to unstable. There is no migration from experimental to unstable. -- AndreiPopescu

Debian is released on a regular basis. During development of a release, there are a set of development releases that always exist. These are stable (the current release), testing, the next release which is currently in development, and unstable, the release which is constantly updated and in active development. Only stable is recommended for production use.

Current Releases

  • [:DebianOldStable:oldstable] - The previous stable release (3.1) ([:DebianSarge:sarge])

  • [:DebianStable:stable] - The current stable release (4.0) ([:DebianEtch:etch])

  • [:DebianTesting:testing] - The next generation release ([:DebianLenny:lenny])

  • [:DebianUnstable:unstable] - The unstable development release ([:DebianSid:sid]) (new packages are introduced here too)

  • [:DebianExperimental:experimental] - Not really a release, but where new packages are introduced
