Debian Unstable (also known by its codename "Sid") is not strictly a release, but rather a rolling development version of the Debian distribution containing the latest and greatest packages which have been introduced into the Debian system. If you are a hardcore developer or tester you should use this release. If you are a power user you might also consider using Debian Testing. The best practices described below are applicable to testing users as well.
