High Quality Content by WIKIPEDIA articles! In the Debian jargon, unstable is the development distribution of Debian. It is codenamed sid (after the boy next door who broke toys in Toy Story). As unstable never becomes testing, this codename is permanent, contrary to the codenames of stable and testing, which have volatile codenames (for instance, stable is currently[update] known as lenny, but was etch before Debian 5.0 was released). unstable has some newer packages, but suffers from an unusually high number of serious bugs, as many packages are new. In development periods, the number of bugs considered "Release-Critical" by the Debian project in unstable is typically between 2 and 3 times as many as the number in testing.
