FreeBSD is a free and open-source Unix-like operating system descended from Research Unix via the Berkeley Software Distribution (BSD). FreeBSD is a direct descendant of BSD, which was historically called "BSD Unix" or "Berkeley Unix" (in violation of the UNIX trademark). The first version of FreeBSD was released in 1993, and as of 2005 FreeBSD was the most widely used open-source BSD operating system, accounting for more than three-quarters of all installed BSD systems.1


Release Information

FreeBSD releases are classified into Production Releases and Legacy Releases. Production releases are best suited to users looking for the latest new features. Legacy releases are for users wishing to stay with a more conservative upgrade strategy.2

Tracking a Development Branch


FreeBSD-CURRENT is the “bleeding edge” of FreeBSD development and FreeBSD-CURRENT users are expected to have a high degree of technical skill. Less technical users who wish to track a development branch should track FreeBSD-STABLE instead.3


FreeBSD-STABLE is the development branch from which major releases are made. Changes go into this branch at a slower pace and with the general assumption that they have first been tested in FreeBSD-CURRENT. This is still a development branch and, at any given time, the sources for FreeBSD-STABLE may or may not be suitable for general use. It is simply another engineering development track, not a resource for end-users. Users who do not have the resources to perform testing should instead run the most recent release of FreeBSD.4

Upgrading FreeBSD

freebsd-update fetch

The system must now be rebooted with the newly installed kernel before the non-kernel components are updated.
shutdown -r now
After rebooting, freebsd-update(8) needs to be run again to install the new userland components:
freebsd-update install
After updating installed third-party applications...
freebsd-update install
Finally, reboot into 11.1-RELEASE
shutdown -r now
