Debian GNU/Linux 3.1 -- Credits (or Blame)
Release management
This release of Debian was managed by Anthony Towns, Steve Langasek, and Colin Watson.
Installation System
The rewritten installation system featured in this release was made possible through the efforts of many Debian developers, translators, documenters, testers, and users -- too many to mention, in fact. Joey Hess led the team during the period of the Sarge release.
