Release Engineering Documentation
FreeBSD Release Engineering
This document details the approach used by the FreeBSD release engineering team to make production-quality releases of the FreeBSD Operating System. It describes the tools available for those interested in producing customized FreeBSD releases for corporate rollouts or commercial productization.
Release Engineering Team
The primary release engineering team is responsible for approving MFC requests during code freezes, setting release schedules, and all of the other responsibilities laid out in our charter.
Primary RE Team ([email protected]) : Glen Barber, Konstantin Belousov, Bryan Drewery, Marc Fonvieille, Xin Li, Colin Percival, Hiroki Sato, Gleb Smirnoff form the primary release engineering decision-making group.
The builders release engineering team is responsible for building and packaging FreeBSD releases on the various supported platforms.
Builders REs ([email protected]) : Marcel Moolenaar, Yoshihiro Takahashi, Nathan Whitehorn
The third party packages in the Ports Collection are managed by the portmgr@ team. Among many other responsibilities, the port managers keep the ports cluster running smoothly to produce binary packages.
Package Builders ([email protected]) : Mathieu Arnold, Antoine Brodin, Baptiste Daroussin, Bryan Drewery, Ren� Ladan, Steve Wills, Adam Weinberger
Old Releases
The FreeBSD Project does not maintain a complete archive of old release ISO images, but many of them are available at ftp://ftp-archive.FreeBSD.org/pub/FreeBSD-Archive/old-releases/.
Older releases that are no longer present on any FTP mirror might still be available from CD-ROM vendors.
