25.1 Synopsis

FreeBSD is under constant development between releases. Some people prefer to use the officially released versions, while others prefer to keep in sync with the latest developments. However, even official releases are often updated with security and other critical fixes.

This chapter describes how to track the development system and the basic tools for keeping a FreeBSD system up-to-date.
